Title: Aerokits Sea Rover, I think
Post by: madwelshman on December 03, 2020, 10:53:57 pm
Hi folks,[/size]So, last night I rescued what I believe to be an Aerokits Sea Rover (unless anyone can tell me different?)
It is slightly damaged, to say the least and incomplete too.At some point, someone has fitted an additional 2 shafts to it and it ran 3 electric motors after the ic motor had been removed.My plan is to remove the two additional shafts and if I can get hold of a plan, remake the damaged parts (cabin sides mainly from what I can see so far), plus the missing parts (cabin roof etc), fit a nice brushless motor (nothing too silly) and then once finished, just enjoy using it.So my question is, does anyone have a set of plans for a Sea Rover? PDF or paper, I don't mind which.Attached is the only picture from the advert. It was crying out to be saved and to get some attention.Will

Hi folks,


So last night, I rescued what I believe to be an Aerokits Sea Rover (unless anyone can tell me different?)
It is slightly damaged, to say the least and incomplete too.


At some point, someone has fitted an additional two shafts to it, so it ran with 3 electric motors after the ic motor had been removed.


My plan is to remove the extra 2 shafts and if I can get hold of a plan, remake the damaged parts (cabin sides mainly from what I can see so far), plus the missing parts (cabin roof etc), fit a nice brushless motor (nothing too silly) and then once finished, just enjoy using it.


So my question is, does anyone have a plan for a Sea Rover please?  PDF or Paper, i don't mind which.

Some strange 'Stuff' inside the hull  :o
It's almost like epoxy that hasn't cured, but isn't sticky either.  It's got a sort of waxy feel to it and if you try to break big bits that I dug out, they just snap quite easily.


One picture shows some of said 'Stuff' on the bow after I have dug it out.


Anyone know what it might be?

I see that it says Spearfish on the stand but if it's 42" it has the look of a Huntsman 28 about it.

Well done Harry but can you make it quicker next time!  :-)

Chris,
Yes it does say Spearfish on there, but is the wrong shape/profile hull to be a Spearfish.
I think it's either a 28 or a Huntress.

Yes and the model length was 42", I have one here that I built many years ago.

I will try to look out an old ad for the model when I get a chance but if you google "Veron Huntsman" you'll find lots of reference ...  :-))

Post by: ChrisF on December 04, 2020, 02:29:38 pm
It could be a Veron kit build which is why I said that the 42" length suggested it being a Huntsman 28. But Vic Smeed also produced drawings for a 42" version as well, so it could be either, but the Veron is probably more common.

Here's the Veron kit drawing.

Everyones idea of a lost cause is different.
I didn't see this in that way, more of a challenge to make good something that would possibly be binned or thrown on the bonfire.
I'm actually looking forward to attempting it, seeing if my skills are up to it or not. Should be fun if nothing else.

Title: Re: Aerokits Sea Rover, I think
Post by: zooma on December 04, 2020, 07:42:27 pm
Hi Will,

I have removed quite a few prop shafts (for various reasons) over the years - mainly from old boats that I want to improve or that had their original shafts that were not put in "square" and needed replacing.......or some that have simply "worn-out".

It is always important to remove the motor and coupling from the hull first (if either are still in place) and the inner shaft too as it is only the outer tube that is bonded into the hull and a loose inner shaft will not be helpful if left in place.  Anything that could get damaged that is in the immediate area such as a rudder or water pick-up should also be removed first.

It there is any large amount of excess filler around the shaft this can be cut, filed or ground away first to weaken the joint before the next stage.

As most prop shafts are held in with epoxy resin, glass fibre, or a mixture of all (including car body filler paste) I take advantage of knowing that they all embrittle with age and I have found that a good sharp bang on the end of the shaft is often enough to shatter the bond and for the shaft to become loose enough to pull out.

It is important to use a hammer head for this technique and not a mallet or any other "soft" surface as it is the shock that causes the hardened packing around the shaft to shatter or crack away.

If the prop shaft is to be used again, a piece of flat mild steel plate can be placed squarely across the end of the shaft so the shock impact is still transmitted OK but the hammer blow will not distort or damage the end of the prop shaft if the blow (or blows) were not delivered accurately enough to land centrally and square on the end of the shaft. 

This technique does need firm commitment as gently "tapplng away at it" seldom works unless the tube is already fairly loose.

Stubborn shafts that begins to slide up into the hull but remain too tight to extract even after some twisting etc sometimes need to be tapped back out again and this "back and forth" movement will eventually do the job.

Once the shaft is loose and can be "wiggled" around it will usually be possible to extract it although some may need any "caked-on" filler etc to be cleaned away first before  trying to pull it out of the hull as the hole it needs to pass through will probably not be much bigger than the diameter of the brass tube itself.

It is important to hold the hull to stop it moving to prevent any damage.  I often wrap an old folded towel around the bows and then place it against a wall so the shock remans focused on the prop shaft but the hull remains stationery

Good luck - any problems - give me a call.  This method has never failed - and I have removed a lot of prop shafts on my own boats and to help others that could not get them out or were a little nervous about giving the prop shaft a firm enough clout!

Stay safe!


Bob.

Title: Re: Aerokits Sea Rover, I think
Post by: zooma on December 04, 2020, 08:18:45 pm
Hi Will,

Those big blobs of epoxy should be removed before banging on the end of the shaft.

Sometimes lumps like this can be prised away, scraped,  or split and levered away as they tend to shrink as they harden over the years - and those look like they have been there for a few years!

I would also check where they pass through the bulkhead to see if any dried-on blobs of filler or epoxy can be removed first as well. If they should be well bonded into the bulkhead it could split if the adhesive/filler does not "let go" at the same time as the keel bond.

If any excess blobs of adhesive/filler are firmly set and show no movement at all, a Dremel and a stone can be used to grind away the volume to weaken the joint before bashing the shaft as it will reduce the stress on the hull skins and the weaker joint will come away easier.

Always remove as much filler/adhesive as you can as the firmer the shafts are held in the hull, the greater the chance of causing any collateral damage as more shock would be needed to shift them.

Stay safe,

Bob.
Title: Re: Aerokits Sea Rover, I think
Post by: madwelshman on December 04, 2020, 08:43:52 pm
Bob, I can't remember off hand if the tubes are bonded or filled around where they pass through the bulkhead, so that's something I will have to check. I will remove as much/any excess or loose epoxy/filler/etc before I give them a whack  <*<   :}


I will post how I progress, slowly I'm sure.


Will
Title: Re: Aerokits Sea Rover, I think
Post by: zooma on December 05, 2020, 05:35:00 pm
Take it steady Will - removing all the surplus "gunge" first to weaken the bond (whatever it was they used to glue the shafts in with) and this technique will get those extra shafts out for you.

Three prop shafts does seem a bit excessive for a Sea Rover - but it does actually looks quite good - I wonder how well it run?

Controlling three motors would have been a bit of a pain - and working out which way to make them all rotate wold be interesting too!

A single motor will be a lot less hassle - thats for sure!

Bob.
Title: Re: Aerokits Sea Rover, I think
Post by: madwelshman on December 05, 2020, 10:52:33 pm
I think that this was done a long time ago, when your options were a sealed lead acid battery, or a ni-cad. The SLA battery would give a better run time, but being so heavy may well be the reason why multiple motors/drives were fitted, to try and give a half decent performance and overcome the weight.
Brushless and a lipo is definitely the way to go, being so much lighter and more efficient.


So, although triple drives is interesting, I am definitely going to convert back to a single instead.


Maybe next week will be (attempted) D-day for the additional shafts.


Will
Title: Re: Aerokits Sea Rover, I think
Post by: madwelshman on December 07, 2020, 09:17:29 pm
Well, a 'little' bit of progress made today.


Sea Rover has now gone from triple screw, back to single screw  O0 (well, there aren't any props, just shafts and tubes, but you get what I mean)


Thankfully, the stern tubes weren't bonded into the bulkhead through to where the motors were, so I chopped through them with a grinder in the length between the hull bottom and the bulkhead. This allowed me to withdraw the stubs from the bulkhead and allow the longer length of shaft/tube to move a little when I pushed it side to side in the epoxy. I also removed the shaft support below the hull, to allow it to move more easily.





Title: Re: Aerokits Sea Rover, I think
Post by: madwelshman on December 07, 2020, 09:20:41 pm
With a pair of pipe grips, I was able to twist the stern tube in the epoxy and move it around until it was free enough to extract from the hull.


I know to many of you this is only a very minor thing, but for me, it's a decent step and the first job partly done.

Title: Re: Aerokits Sea Rover, I think
Post by: madwelshman on December 07, 2020, 09:22:42 pm
The next job, i think, is to tidy up the hull (inside and out) where the removed stern tubes were, fill the holes so it's water tight again.
Title: Re: Aerokits Sea Rover, I think
Post by: madwelshman on December 07, 2020, 09:24:53 pm
Can anyone advise me on what to use and the best way of sealing those holes up please?  :-))

If it was me I’d measure the diameter of the prop tube you’ve removed, find a piece of dowel the same diameter and fill the hole with that well glued in then plane to surface,  fill and paint.

Hi Will

Great that you got them out without too much trouble and without any damage. If it was me, before dealing with the holes I'd get rid of all the paint off the outside of the hull and fill using P38. I'd then treat the whole of the outside of the hull with Eze-Kote resin and lightweight cloth which will tie everything together and provide a uniform and stable basis for painting.

I 'd also replace the timber support to the remaining prop shaft (is the prop shaft Ok?) as it looks like a dog's hind leg, is too thin and maybe is insecure and has some rot? Now is the time to make sure everything is sound.

Chris
Title: Re: Aerokits Sea Rover, I think
Post by: madwelshman on December 08, 2020, 08:35:08 am

Thanks Chris, I was quite pleased at how well they came out to be honest.


The plan was/is to clean/sand things back where the holes are and see what the hull is like under there before filling the holes.


You would recommend the eze-kote would you?
I've never used it before or the lightweight cloth either.


The keel/prop shaft support isn't brilliant and will more than likely need replacing I believe.  I'm guessing I need to cut off the section that needs replacement and cut a new piece, shape to match and glue it on?


The centre prop shaft, I haven't assessed that yet and may well need replacing too if it's bent.


Plenty to do still, and that's just on this boat  %)


Will
Title: Re: Aerokits Sea Rover, I think
Post by: zooma on December 08, 2020, 09:41:24 am
Plugging the old shaft holes with dowel is a good idea, or you could shape some scrap wood to fill the gaps.  I usually make any plugs individually to be quite a tight fit and gently tap them into place after coating them and the hole with 24hr Araldite.  If you also make them a little over-size in length they can be sanded back after the glue has dried to give a perfectly finished repair.


The epoxy will fill any less that perfect gaps as removing the old shafts may not have left perfectly shaped round holes, and the slow curing epoxy gives you time to work and will give a stronger bond than a 5 minute epoxy (or similar fast drying epoxy adhesive). I usually cover the joint area with masking tape to keep the adhesive  contained as the epoxy can flow a little as it seals everything and starts to cure.


If you are going to change your remaining shaft for a new one you can see if the wooden skeg/tube support is still sound or rotten. If you are going to keep the existing shaft you can sand back the paint around the joint to see if the wood is sound and see if it is just some poor paint and filler that is making it look worse than it is - the wood underneath could well be OK.


My last completed restoration was my Rapier and that has been in constant use since it was finished. This model could be a similar age to your Sea Rover and also needed a fair bit of new wood with new cabin sides etc.


I used Aliphatic glues on any wood to wood joints and 24 hr Araldite to bond in the original shaft after removing it to rough-up the outside of the tube to give it a good bond into the original wooden keel.


I never used any cloth coating on the model. I sanded everything to give a smooth surface that included a real mix of old paint, new paint, P38 filler, old wood and new wood  etc (a typical mix when restoring and mixing "the old with the new") and painted it.


Since then the Rapier has been driven really hard (and probably a lot faster than the designer ever intended), but it has been reliable so the traditional finishing methods of wood primer, undercoat and topcoat have worked well and any future maintenance or repairs that may be needed can be tackled the same way.

Bob,


Thanks again for your input (and everyone elses too of course), all gratefully received and taken in.


I haven't really done anything with wooden hulls before, so all of this is new to me. But, I'm eager to save this model and improve both my skills and knowledge along the way. So far (not that I've done much) I am enjoying myself, but am keeping the end result firmly in my mind as both my goal and motivation.


There is movement in the timber below the stern tube and I think at the moment, that it is just a case of having come away from the outside of the tube. But, I don't yet know if there is any rot in that timber or not.  I'm sure all will be revealed when I sand it all back.


Will
Title: Re: Aerokits Sea Rover, I think

Does anybody have any suggestions please?


As previously mentioned, I need to replace the cabin sides on the Sea Rover, but they are bonded to the frames and transom before the hull is decked (see attached picture).  I don't really want to go as far as removing the deck unless I REALLY have to.
Is there maybe a way I can slice down the side of them, between the cabin side and each frame, to cut it away? I did wonder about a multi tool with a the thinnest cutting blade I can get?


Will

Post by: zooma on December 11, 2020, 10:01:08 am
Hi Will,


I had exactly the same problem when I started to restore my Rapier and decided to cut away the old cabin sides and replace them with new ones.


If you take a look at the Rapier thread on here you can follow the progress because I would think that most of what I had to do will be very similar you what you are going to do.


I found a Tamiya razor saw was very helpful and allowed me to remove the cabin sides completely.


Take a look at the thread and if you need any help, don't hesitate to contact me.


Bob.



Title: Re: Aerokits Sea Rover, I think
Post by: ChrisF on December 11, 2020, 10:02:27 am
Hi Will

You could use a razor saw. But as the coamings and rear part of the cabin look quite good a better way might be to leave those parts in, cut the top off the rest of the cabin, the front part, flush with the deck. Then cut out some new cabin parts so that they sit on top where the old ones were cut off and glue a strip of timber alongside the inside of the joint - maybe fit that first so that the sides can butt up to it.

You could also add an extra skin to the inside of the cockpit sides if extra strength is required. And a cap along the top to cover the joint and finish it off.

However Bob is the renovation king so may have a better solution.

Chris


Edit: Bob just beat me to it!

Post by: tonyH on December 11, 2020, 10:46:45 am
Hi Will,
I've had similar situations in the past and I've used a junior hacksaw blade with the pins removed. You can also bend them to suit the odd spot or even break them to suit if necessary and another advantage is that you can reverse the cut to the pulling stroke. I've also used an old feeler gauge blade with teeth cut in with a dremel cutting disc.
Good Luck

No problem Will.

If you also read the Rapier thread on here you can see that I have tackled every job that you have to do on your Sea Rover.

Once you get started I am sure you will enjoy solving all those little problems as they come along - and you will probably find better ways of doing some of the jobs than I did.

The Rapier was my second restoration, the first was a TID tug that had a good glass fibre hull, but everything else was a mess, so I removed everything from the hull and used that model as my first experience of building from a plan - and my first experience of working with plastic sheet!

The Rapier was my first experience of restoring a wooden boat and with no plan to refer to.  Part way through the rebuild I was able to buy a plan, but it turned-out to be a typical "kit plan" that showed non of the bulkhead shapes and windscreen details that I would have liked - and by the time it arrived I had already solved the problems.

Once you cut the cabin sides out everything else will come together.

Good luck  - but be careful - this restoration lark can become addictive! :-))

Bob.
Title: Re: Aerokits Sea Rover, I think
Post by: madwelshman on December 12, 2020, 10:03:57 am
I have a good bit of info to refer to now, thank you Bob.
So this week if time allows, I'm hoping to do something with the removed prop shaft holes and get those blocked off, filled and sanded back.
I also plan to cut out some cardboard templates that I can offer up against what is already there. Then I can try and work out how drastic the surgery on the Rover will be.
Whether I attempt to remove the sides completely and fit new ones completely or cut them down to deck level and butt the new sections on top, I'm not sure yet.
I also need to inspect the remaining centre shaft and make sure it is serviceable. If not, that's more surgery  :((


I am looking forward to making a proper start on it, but I'm also a little apprehensive too  :o
Once I start though, A, I'll have no choice but to carry on and B, once it starts looking a little less unloved, damaged and getting some shape back to it, that will boost both my enthusiasm and confidence.

Try and make a list of all the ply and timber that you will need including any small sections for finishing off to make the postage worthwhile. Even if you get too much it can be used on other models.

As Chris suggested, I am trying to compile a list of multiple products that I can order in one hit.


3, 4 and 6 mm ply to start with.


Clear plastic for glazing, what thickness do I need to get as an all rounder?  My Sea Rover, Veron Huntsman, 34" Huntsman and presumably Sea Commander (when it eventually arrives) will all need glazing fitting, so I may as well get it all at in one go. 
I'm guessing that I can use the same thickness for all of them?

SLEC only do 0.5mm (clear rigid PVC) which is what RadioJoe used in his Hunters Moon build so easy decision.

I need to put an order in as well and try and follow my own advice by including all I need. I shall probably fail!

Ply or lightply?


Well, it's mostly for cabin sides, cabin roof and cockpit floor.
I presume I need liteply?


I'm presuming the difference between the two is literally the weight compared to ordinary ply? Hense the name liteply?

I have been checking out other sites as well as SLEC, (eBay and other model shops) for the glazing material and have seen anything from 0.1mm upwards.


I'm thinking some 3, 4 and 6mm sheet, some clear plastic/pvc for the glazing, slo zap to start with.


I haven't worked out what else yet.


Good luck with your list Chris  :-))

Liteply is easier to cut and sand but personally I don't use it - there are pros and cons which have been discussed at length before so we won't go there - I use birch ply. For glue I'd suggest aliphatic resin as your main wood glue, plus as you say Slo Zap plus some thin CA. For gluing the glazing best to use canopy glue which dries clear. Apart from the Slo Zap I use Deluxe Materials for glues.

Have you got much in the way of tools? PermaGrit blocks and files are a must for me.

Thanks Chris.


Slightly different I know, but I'm a mechanic by trade, so do have some tools that will be useful for this. Files, check. Permagrit block, check. A few knives and scalpels too.
I will need to get a few other tools as time goes on though.

I've got quite a few DIY tools together over a number of years, some of which like yours have come in useful, and my Workmates have been very useful. As well as the PermaGrit other tools I use a lot are razor and flush cutting saws which were mentioned earlier.

Even though I scratch build the only big power tool I've bought so far is a scroll saw which has been invaluable and has seen lots of use.

Some more model biased tools are what i need to start building up, saws being one of them.
As time goes on, I'm sure I'll find things I need to get to tackle certain jobs.

Have you got a fretsaw and a "V" cutting table? Possibly one of the most useful hand tools if ply involved. Especially for window holes etc.
Title: Re: Aerokits Sea Rover, I think
Post by: madwelshman on December 13, 2020, 11:12:53 am
Tony, no to either of those.
To be honest, I'm not sure what a V cutting table is  :embarrassed:
Oh how I have so much much to learn.

Don't worry Will I don't know what a V cutting table is either!

Ah ha, that makes sense now. Cheers Tony.
That's something that would be easy enough to make.


A fret saw is something on my list of things to buy and another, different grade Permagrit block.

Well, I managed to have an hour on 'Rover' tonight.


Inspection showed up that the remaining, centre stern tube, didn't have a shaft in it.
So,.......now I have a Sea Rover without any shaft in at all.


Just as well really, because after 'extraction', I found that the tube was in fact bent, but that wasn't visible with it in situ.
Title: Re: Aerokits Sea Rover, I think
Post by: madwelshman on December 15, 2020, 10:27:18 pm
I also ran the sander over the undersides and sides too, just so I could see what sort of condition the hull was actually in.
More sanding is needed still, but it's flattened off a bit where the outer tubes used to come through and given me a better idea of how solid it is.

The other thing I have done this week, is print out the plan, cut out the cabin sides profile and stick it onto cardboard from a cereal box.
I offered it up roughly alongside the better remaining side to check dimensions and profile, they both appear correct, so next job is to work out exactly where I'm going to cut the old cabin sides down to and then do the same with the template, before making some new cabin sides and installing them.

Hi Will

I did wonder about the remaining prop shaft! The hull looks pretty sound though, so once you have installed a new prop shaft and rudder and maybe the prop shaft support/keel timber if required, then you will have a solid basis for a nice boat.

If you can leave the lower parts of the superstructure, below deck, it will save you having to disturb where they are glued into the bulkheads etc. As I said earlier you will need to glue a quite deep strip of timber along where the join will be and then you can clamp the new, upper part of the superstructure to it.

Chris,


yeah, the hull looks pretty good I thought.


I'm thinking about cutting the cabin sides at just below deck level, then the deck will help maintain the cabin shape and once bonded to the lower/old section, plus too the deck, it should be strong enough and water tight (deck to cabin).
If I cut the old sides down to deck level, I will have to insert small sections of sheet brass or similar to maintain the shape between between new and old.
Once I have cut the old sides down and before fitting new ones, I will then fit the new shaft and do as much inside the hull as I can whilst access is better.
I think that's the plan, at the moment anyway.

Hi Will,


How is this project going? My Lesro Javelin restoration is similar but not quite as tricky as yours. Banging out old propshafts and scratching my head about what to do next and how have featured in my project.


Invaluable help from Bob zooma also featured.  :-))

Hi Stuw,


To be honest, the Sea Rover has taken a bit of a back seat at present. I am trying to sort of concentrate on the better of my two Sea Commander instead.
The Sea Rover, I have removed the cabin sides down to deck level, ready to make replacement sides, but that's as far as I've gone with it at present. The Sea Commander needs less work overall, so going to try to get that one finished first and will come back to the Sea Rover at a later date.
As you say, Bob has been a great help (others have as well), offering lots of advice and valuable experience.


The Javelin is a good looking boat and both it and the Rapier are ones that I wouldn't mind having in my fleet at some point.

Hi Will,

I also cut the front part of Rapier 2's front cabin down to deck level over the weekend, and I will start to graft the replacements back on this week.

The replacement  cab parts have been cut but have no windows yet - and this is delayed as I am still messing about with shapes as I am trying to make the boat look a little bit different to Rapier 1.

I am keeping up with your progress on your Sea Commander - stay with it  :-))

Bob.

Post by: madwelshman on March 29, 2021, 08:42:53 pm
Bob, I dare say that will be quite a satisfying job, because the change in look of the boat will be huge regaining cabin sides and will start to resemble the Rapier once again, even with it's few tweaks.  It is a job I look forward to doing on the Rover, when the time comes.


Will

Post by: zooma on March 29, 2021, 08:47:08 pm
Its only a minor tweak Will - but I have extended the cabin roof back a bit - and I am also looking at the rear cabin to see if I can do anything to make that look a little different too!
Title: Re: Aerokits Sea Rover, I think
Post by: madwelshman on March 29, 2021, 09:04:02 pm
It will be interesting to see the end result Bob, especially to compare the little differences here and there to the Rapier 1.
