Title: 85' Harbour Tug
Post by: Antipodean on May 16, 2014, 11:13:16 PM
Out of some sort of insanity or indigestion I decided I wanted to build this boat. I normally work in 1:16 and the plans were 1:24 and gave a finished boat of around 42" so I thought why not, I can make them bigger.
After I asked around (mainly on here) I set to work to get them done.
I did not figure on how big things would get and I have a very limited work space.

The plans worked out to be just a bit shorter than my empty space on my counter.

The original deck plans . Note the 305 mm ruler on the plans.

The original keel and bulkhead plans


(http://i1064.photobucket.com/albums/u372/Antipodean1/IMG_5368.jpg) (http://s1064.photobucket.com/user/Antipodean1/media/IMG_5368.jpg.html)


The new and extremely large main deck plan. Note the same 305 mm ruler in about the same position.
The length is now just on 61" or "Sorry Dear, I'll move it"
Now I just need to source materials for the decks. I already have an abundance of 2.5 mm oak boards to build the keel and the bulkheads from and when it comes time for the superstructure that will all be from oak as well.
Not sure if this was a good idea but if I only build one large vessel it might as well be this one.
I am hoping it ends up looking a lot like this one.

Had to spend a little time redrawing half of the plans but managed to get them close to where I can fudge them if I have to.

I put the Lady Lou in front for a comparison

Next is the part I don't like too much, cutting outside the lines.

Instant tug, just add elbow grease and glue and stuff.

Test fit of bottom deck

Test fit of bulkheads
(http://i1064.photobucket.com/albums/u372/Antipodean1/Harbour%20Tug/IMG_5654.jpg) (http://s1064.photobucket.com/user/Antipodean1/media/Harbour%20Tug/IMG_5654.jpg.html)


A few notches need to be cut deeper and a bit more shaping and then it will be time to test fit the upper deck.

Thanks Martin, I am trying something new with this tug --- Patience.

Test fit of bulkheads and upper deck. Only broke one bulkhead but it is glued and clamped and hopefully fixed.

I keep setting the Lady Lou next to what I am calling Giganto for now just to remind myself that this is not the best idea I have ever had.

Well, apart from the cold wind tearing through my yard it has been a beautiful day. Once I got my chores done I decided to dust off the beast and start working on it again.
Started correcting the shape of the ribs, when I enlarged the plans I got a few "errors" that needed fixing. I have nearly got one side done and then I will make templates from there and work on the other side to make sure it is all even. I will have to glue another layer of ply over the deck to correct the mistakes there too.
She is coming along, slowly.

I have been very slow on this one, I have spent the last year or so being a good Dad and Granddad. My daughter was finishing college and getting sorted out in her career so I got to babysit the wee one for her. Turns out they can be kind of cute when you get to know them.
I only had to alter 2 of the ribs, one needed nearly an inch shaved off the outside.
I am picking up some cedar to rip into planking for the first layer, then a coat of glass and then planking with some nice oak I have laying around.
Once I get it watertight I am will be looking forward to seeing how much ballast this monster will need.

Finally able to get back to work on her, lots of delays but finished planking and started the bodyfiller work.

Finally got my prop and my "instant diy rudder kit" in the mail today. Should be a bit of fun making it. The prop is a Prop Shop 4045 which still looks small when I test fitted it on the shaft.

Spent the afternoon cutting out the basic shapes and marking for the slots that will let it all fit together.
Title: Re: 85' Harbour Tug
Post by: Capt Podge on May 19, 2017, 09:37:53 PM
Is that a rudder coming together ? ... or a barn door! {-)

Forgive my poor attempt at humour - good to see you making progress. :-)

Regards,

Ray.
Title: Re: 85' Harbour Tug
Post by: Antipodean on May 20, 2017, 01:45:58 AM
I think at 15cm tall it would make a good barn door Ray.  :-))


I just have to source a few more items and I can get it together, the cutting the notches is the worrying part.


As usual progress is a dead stop then a rush of too many things to do at once. Still, it is fun when I can get to it.

Hi
 I'm new here.
 Just saw your post on your new tug.That'll keep you busy for a while!
My question today id regarding the 'Lady Lou'.
I like it!
Could you tell me more about it?
Is it a kit or scratch-built?
Thanks for any help...
     Hugh
Title: Re: 85' Harbour Tug
Post by: Antipodean on May 21, 2017, 02:31:14 AM
Hi Hugh, welcome to the forum.
The Lady Lou is based on the Thames River tug Plaudit but I freestyled the superstructure. She is scratch built from a set of plans I happen to have in front of me on my desk here.


If you want to see more river tugs you can go here http://thamestugs.co.uk/LION---ROTIFER.php and there is a lot of other sites that show these great little workhorses.

Ian

   Thanks for getting back to me.
 I'll look into thamestugs.co.uk.
 And I'll also do some searches.
 The Plaudit(Lady Lou) model is really cute...

After a few hours with a hacksaw and a needle file I have manage to get some of the slots cut. The rest will be done slowly after work each day as the week progresses.
Title: Re: 85' Harbour Tug
Post by: Antipodean on May 24, 2017, 12:04:31 AM
I have finished all of the cutting and here is the "barn door" dry fitted together.
All the needed bits and bobs to silver solder it are ordered and now I get to start doing the final shaping and cleaning.
Can anyone suggest the best thing to use to clean it before soldering please?
Title: Re: 85' Harbour Tug
Post by: tsenecal on May 24, 2017, 02:23:52 AM
don't bother cleaning it, but...

use this flux, with this solder...  i have used this exclusively for all my structural soldering for 30+ years.  I would cut off my left hand before giving it up.

Post by: derekwarner on May 24, 2017, 02:25:38 AM
Looking  good+large :D......

Cleaning the surfaces is important........1200 W&D paper will polish the surface, however it does leave a fine dust deposit which does need to be cleaned......Isopropyl 99.8% alcohol will remove this

An alternate to the W&D paper is non soaped steel wool  :-)).....

Having said this, you have quite a mass of brass that will require a general preheat over a refractory brick surface before to the actual or second torch heat for the silver soldering process

This preheat [complete with the fluxed surfaces] will tend to distort the plate surfaces + the reinforcement bars

From this, you could consider pinning the reinforcement bars with say 1mm brass wire as retaining rivets to stop distortion  <*< of the reinforcement bars

Again, you should research the actual S/S + fluxing process prior to commencement......cupalloys.co.uk  have some great on line tutorials......well worth reading O0

Thank you for the advice guys.
I already have the solder, given to me a long time ago. It is Harris Safety Silv 45.


I have a lot of filing to do to get the edges shaped before I can do anything but it looks like my shopping list is growing when it comes to prep, soldering and cleaning.

Slowly grinding on, lots of other things acting as brakes on most of my projects these days.
The first pic is the rudder, prop and skeg test fitted. The second is with the Lady Lou beside for scale and with 90 lbs or 41 kg of ballast to bring it within a couple of inches of the waterline.

Actually dragged her out today because there was no rain in sight. Built a basic superstructure which may be developed or scrapped depending on how things go. My wife insists I finish the other boats and then get this one on the water.


I have 2 airboats, one speed boat and my knock about for the grandkids to get done in the next couple of weeks.


I am still needing to go and pick up the lead for the ballast and waiting for the brass rod to arrive for the bollards. The port and starboard tow attachments have to be hand carved as they are basically giant deck cleats.

Hi Ian, build is coming along really well, just wondering what her ballasted weight will be.
Keep up the good work  :-))


John


Title: Re: 85' Harbour Tug
Post by: Antipodean on August 07, 2019, 11:08:08 PM
At the moment John she weighs about 30kg but I will be making removable ballast from old car wheel weights and looking at between 35 to 50 kg. I believe once I have all of the permanent fixtures in place and sit the battery in there it may only need 30 to 40 kg but it doesn't hurt to have the extras just in case.
