Right it was about time that I built one of these wonderfull crafts so I can reek havoc as well as the rest of you at mayhem bashes.Allright I know I don't need a springer to reek havoc me just being there is enough!!!
Right Me being lazy have bought a hull from our Scottish connection Norry and good it is as well,now Me being Me decided it had to be different and yes you guessed it more powerfull than the rest,well it would not be one of mine without power would it.So I decided after seeing sense ,well I was going initially going to put a MFA 850 in one but saw sense,just about!,so in is going a Scothell drive that I just had lying around mated to a Graupener speed 600. This unit I do believe is not the Graupener but a Marx unit and I must admit is quite powerfull time will tell.
Work so far has involved fitting of the drive unit and the servo for steering it,see pictures more to follow as build goes along.Have decided for ease of servicing etc that the whole deck will be removable by screws along the top of the deck with access to the batts via the superstructure with a seal around the deck flange picture to follow on that.

hmm interesting.
I started my super springer today, going to have two steerable korts! O0 ;D O0 {-) {-)

Looking interesting Stavros..
Would be interesting to see how she performs and how well she pulls with the Schottle drive...
By the way, with a light hull, a 7.2v pack.. you are going to need a couple of house bricks as ballast..
Boatmadman..
We need more details.. and pics...
Both of you..
Scoot bollard pulls 2lb 14oz.. :D
Mustang Sally bollard pulls 4lb 4oz... :o
You think you can beat that?... :P
-
hmm - gauntlet is down!
No pics yet, just knocked up the basic hull yesterday, working out hardware requirements next.
Ian
-
ok Toesupwa how do you measure you bollard pull
Stavros
-
...and how do you measure pushing ability or is that the same :-\?
-
Looks interesting Stavros this could the start of many more schottle driven springers :o
glass fibre hull aswell where on earth did you get that from i didnt think anyone produced them.
Jay
-
PM Norry he makes them

I built a small boat for my grandson a long while ago :'( which had one of these in it; Riggers has it now. Mine used a rewound 540, which was quite sedate on 12 volts. You have to be ultra-careful with the rudder linkage i.e. no slop whatsoever, as it's geared up from the servo arm to the actual Z-drive bit. Any slop and you'll be all over the pond - but at least you'll have an excuse for it this time!

Stavros
I tie off a digital fishing scale (any pull scale would work) to something substantial.. tied off to the Springers towing bollards with about 6 - 8ft of line and gently let the throttle increase. Have someone watch the scale and give you the readings.
Dont go for a short line as the 'bounce' of the water from the prop against the 'harbour wall' will give you false readings.

...Hi Guys...
I think I,m going to have a rethink on Wee Johnny,s Common 5/8th Springer Tug now...
I might have to mould a GRP hull for myself & power it up with a Mega Motor & Prop with a Mega Kort Nozzle just to compete with you guys...
You are all going Bodmin (Doc Martin talk for nuts) about these wee boats...
I built Wee Johnny one last year for playing football & also built a Big Brother for it for Steering & Docking competitions next year...
I cant get on with my real Tug Boats for these Springers...Maybe I,m going Bodmin as well...
...All The Best...Norry...

I like the idea of a screw down removeable deck, what are you going to use to seal the deck?
Ian
-
Easy peasy apply a good beat of silicone sealant around the deck perimeter apply PLENTY of VASALINE OR GREASE to the underside of deck screw down and forget.when you come to remove the deck no probs as silicone will stay behind and due to the grease on the underside of the deck it wont stick,told you it was easy,old Indian trick that one!!!!
Stavros
-
nice one stav, ty O0
-
Dave,
I think I have seen that drive somewhere before.
It is a Marx unit and I've still got the prop here to use it without the nozzle.
I gather you don't want the plans for the other one then?
Glad it is being put to a good use.
John
-
No as the sides of the original were damaged beyond repair I decided to use the unit in the springerinstead so it is going to be worked hard!!!!! There was a prop on the unit allready,and I have not forgotten about the other boats!!!!
A ha Me just had thought yes I need the plans,as me found use for the superstructure O0
Right more progress has been made deck edging has been stuck on with p40 and sanded down to give an absolute flat surface to stick the deck on
Stavros
-
I used the silicon trick when making gaskets for submarines Stavros, but found that it could still stick sometimes. Remedey was same method, but place a sheet of clingfilm over the silicon before clamping down, perfect every time after that.
-
Right some progress slowly but surely we will get there.Right deck is on for now,deck coaming fixed,I am going to use a wheelhouse that I had from a scrapped pusher tug which will have to be modified slightly to fit,also an access hatch has been cut to gain access to the Scothel drive, more pictures soon

...Hi Stav...
Your Super Springer is looking good...
Dont depend too much on the power you will get from the schottel...
In my experience with these schottells I found you will get Lots of Noise, Excellent Manouverability, but not a lot of power when it comes to pulling or pushing...
I had a wee tug a few years back with one fitted in it powered by a 6 volt decaperm & it run the bearings & gearing when i used it to push a large sailing ship of a reef in the pond...
I would have a plan B ready just in case...
...All The Best...Norry...

Hello Stavros, I'd have to agree with Norry. I too had a very manoeuverable tug which operated a twin Schottel set up.. Looked lovely on the water but the noise which caame off the (again) Decaperms on 6v was horendous. It could be run on 12v but the vibrations oh my the vibrations. Not much in the way of bollard pull either on 6v a lowly 1/4lb and that was being generous :embarrassed: Still I'd love to build a decent schottel unit and try again with it. The reason is I loved the way you could pirouette arond the steering courses but shy away from towing.
cheers
Jim O0
p.s. Is there anyone up here in Shetland interested in tug towing ?
p.p.s. I intend to build a pair of standard springers for my kids. Can't wait for the two week holiday looming

[b] ...Hi Red Hamish...[/b]
How are things with you & yours...
I take it you have moved to Shetland....Wow ...What a place...I won a trip to the Shetlands at the Festival of the Seas when it was at Leith...
I took my 2 sons with me & we had a fantatsic time...Have you been up to Sullom Voe yet to see the real tugs in action...We spent a day with the guys on the "DUNTER" and it was definately the highlight of the holiday...The guys on the tugs were very freindly & nothing was a problem with them....
Iwould definately take another holiday up there if i could afford it...Are there any good sailing venues near you...If i come back up I will bring some boats with me...
...Have A Merry Christmas & A Happy New Year....Norry...

Hello Norry, Sorry Stavros a bit off topic.
All is well and good on the really bonnie Shetland isles. Aye this is the reason I was not at many of the Scottish events this year. We moved here in July and what with all the preparation of getting the house ready to sell then the commotion of the sale, packing and moving. Well something had to slip and sadly it was only after making a point of getting down to the Greenock MPBC / Largs MBC Scottish tug- in that I managed to persuade SWMBO that I had to do that one if no other. Now to await the schedule of events for 2008 and see which one I can justify the expense of a long weekend away to. Probably manage something in June or August down the Largs way.
As I said in my last post if anyone has plans for making a suitable Schottel drive that isn't too noisy or comsumes power like no mans business then I for one would be happy to get a copy of the plan and attempt to make a Super Springer too.
cheers

Progress at last Hull has been filled and faired and had it's first coat of filler primer which was rubbed down with 400wet/dry,re coated with 3 coats of the same and guide coated with black satin ready for it's final rubdown with 800 grit paper.
The wheelhouse has also been painted this firstly having had 3 coats primer 900 wet/dry and painted with Plasticoat gloss white.And before anyone comments !!!! yes I usually use Halfords but hey come on it was on the shelf begging to be used

Adaption of the kort? And what are the advantages?
Andy. :)

360 degree thrust is what you get
IE; where ever it points is where the thrust is directed

update not had time to work on it will do over xmas me will be in shed xmas day conjutating!!!
Stavros

I put my boat in the bath earlier not much of it got wet, will need a lot of ballast. :)
Andy. O0
-
Right me got totally bored with Xmas so went to the shed and just got on with it
The superstructure was first finished and then painted white with plasticoat,Brass hand rails have now been fitted and are awaiting painting black so is the mast and door handles etc,tomorrows job!.The pushing attachments have been made and are ready for painting,the hull will be rubbed down tomorrow as well.A mast was made with brass tubing and a radar(non working) was attached to it.Port and stbd and mast lights were wired up with LED'S and will work form a separate batt,just on a switch.
Stavros

Lookin` good Stavros, going to hit the water soon by the looks of it. O0
-
nice superstructure there stavros ,but those pushing knees are distracting they look wonky or is it an optical illusion maybe your camera or that extra glass of jum bean i had earlier {-) .
daz

portside DON'T panic it's not the Jim Bean they are loose,just hanging there at the moment,I will be spraying the hull RED in the morning then they will be sealed and then painted and fixed properly and straight O0
Stavros
-
Nice one Stavros - your railings do look exceptionally neat. I am very tempted to do one myself but so much to do and interesting presents to fit on the motorbkike....
-
Well this Xmas malarkey is good for boat building!!!! Well it's maiden voyage time tomorrow me thinks,got the hull painted this am deck was also sealed and grey primer applied,spent ages painting the railings and good they lookeven though I say it myself !!!!!!The scothel drive and motor has been installed and the deck sealed on.Jobs to do in the am fit speed controller and all electrics etc fit the Pushing knees bath check and away we go,sound simple doesn't it.
Stavros
-
Looks exellent Stav, I am waiting with interest to see how she performs on the water!!!
Mark.
-
Looks great Stav, guess the prototype was all-electric ? No Stacks, funnels,exhaust pipes, up-takes, lums, chimlies ???? Got a name for her/it yet ? Dont mind if it is in Welsh ;)
-
There is allways one that will spot the DELIBERATE mistake oops >>:-( I knew I had forgotten something,aw well back to the drawing board.
Looks like me doing some work just to keep arrow5 happy !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
A Name for it not yet will let that one out of the bag after the first sail,it might even be submersible you never know
Stavros
-
Sorry Stav, get it wet anyway. Think you`ll need bulwarks between the knees , if you`ll pardon the expression. ::)
-
There you go again more flippin work !!!! Seriously i had thought of that putting a Bulwark between the knees just to try to keep it dry.Workshop till the old girl is done get it finished etc then sail it or sink it on sat in secrecy,cant let welsh Druid see it before sunday can we
Stavros
-
Right just to keep arrow5 happy !!!!!I have now fitted a bulwark between the knees and fitted funnels,bath test complete no leaks just make batt box for the 6vgell cell BUT it looks from bath test that I might have to go to PLAN B std springer >>:-( >>:-(
It did not seem to me to be very powerfull a proper test will be on sat or sun
Stavros
-
Saturday, that is just time to add the pipes in the stacks and Humbrol on a company livery then, or have you only got red paint? he he he :D {-) ;D O0
-
Bloomin Heck we have a professional HECKLER on this site now!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Stavros
-
I've got that same drive unit in an older Dozer boat hull - I found I had to change the prop and also run it on 12V rather than 6v - just didn't have the power I thought it should have. Older units might have actually come with two different props. I look forward to your pond tests. It looks good.
-
You need bigger FUNNELS thats your problem...
;D
plus you have got a lazy stantion..
-
Thanks Mike and Banjo...I thought he was going to hit me :'(
-
I think he is rushing things!!
{-)

The submarine is allready at your pond awaiting your arrival ;)

Yeah ha she got her botty wet,and boy was it fun WHILST IT LASTED!!!!!!!!!!!!!!!!!!!!!!!!!!
Blunder no1 me forgot teh batt for the springer at home BUT luckily on eof our lads had 2x6v 4amp batts in his car so to heck wiht it I sad lets run 12v boy was it fun,was it quick.........YES,was it manuverable.............boy oh boy was it, did it last .....................................NO >>:-( >>:-( >>:-( >>:-( >>:-(
There it was going along nicely when DISASTER stuck,I only managed to strip the teeth on the drive leg so back to hte drawing board,BUT help is at hand cos me is now going to buy a new one from the Model dockyard,so watch htis space,
Stavros

O0Congrats Stav, Stripped gear eh, too bad. Some things just arent meant to be :( Next................ ?!!!

Looks good on the water Stavros!
Any reports on manouverability?, pull?, the bow wave?....

hi stavros you said the gears striped on your drive unit. The unit you have was made for the model seabex1 if i am not wrong. This unit was delecet at the best of times, but since then graunper have made a new stronger unit . They rec there 720 tourque motor for it so you could use your protech unit.

Well it could spin continuously in its own length and it pushed my Northsider along sideways, and the bow wave was quite impressive. Shame about the drive problems later.

It lives .....I think stripped down the drive unit today only to find that there was some 10mm play between the prop and the drive peg so me has concluded something has broken or fallen off so the bottom cog was moving away from the other,so made up the difference with washers!!!well had to use something so testing will probably take place on Thurs in the bosses pond,ssshh don't tell him
