XRAD'S LIVE STEAM 1/24 BROOKLYN TUG
« on: February 18, 2021, 10:49:22 pm »

Hello All,  Been a while since last post. Built many model projects and wrote many C++ model codes in the last few years. But now, I am am working on a new 1/24 scale Brooklyn tug based on original blueprints from Camden NJ USA shipyard(my home county!).  It will have either a mildura or Stewart marine twin and a home made scott boiler....should be a cool project. I built one of the 1/32 scale dumas tugs in live steam a few years ago and it is tied with my lightship models as a favorite subject.  Here is a pic of hull plans. 52.5" stem to stern length, 12.5 width (may have to adjust a bit for seaworthiness)

This looks like an interesting project. I have no experience of steam models but I'm happy to tag along and see how it develops.


Regards,
Ray.

Oooohh-- I wanna see them planks go on. i had no idea how to plank a tug, so I made it up, and used this unorthodox method, using all straight 1/8 x 1/4 cedar sticks --no steaming, no tapering. The keel was installed after the hull was made, and curvy part next to the keel was made with epoxy filler WEST 410.


It will be fun to watch you do it--probably the "right way"; the lines are similar to St Andrew

I was a particular fan of “Moran” tugs in the States during my travels.

Hi everyone! Thx for replies! I don't know if there is a 'right way,' whatever works is always fine.  yes, I have missed boat building...forgot how much fun it is!  So the hull frames and stringers in rough orientation. Hull will be glassed so not too concerned about minor details at this point....I added 3/4" of freeboard to make here a bit more seaworthy...

rough wood planking..looks don't matter here.  Then a wipe of bondo fiberglass resin over the planks, which makes a better coating for the 5 oz cloth.  Then lay on the glass. Then coat with more resin.  When resin dry, a light sanding. Then thick coat of woodland scenics modelling putty(it's like spreading cool whip..and it's the cheapest of the light model pastes..). woodlands putty is light and very easy to sand. great for building up the hull where needed. great for filling gaps. 

after dried and faired, then the real hull build begins...Not sure if I will make a split mold or just glass inside-out a one off....

I'd like to see how you make the mold.

I decided to make a one-off.  Short answer: But if you were to make a mold, you would need to make a perfect hull 'plug' with any detail like rub rails built in.  then put a 'seem' divider down the middle (a doubled thin piece of ply or similar bolted together- not glued). then wax and lay up a gelcoat, then strong glass mat.  Do one side at a time thereby making two halves.  Pop these halves off, polish inside and wax. Then re-bolt halves together. Now you have a female mold master from which you can make the model.

Pretty sure that filler from Woodland Scenics might be the same as deluxe materials and a few others. You might find it way cheaper to use DIY stuff from Screwfix or BnQ for exactly the same product. Pollyfilla make no discernable different product if I remember. I guess the equivalent for you would be Home Depot. I know I've found the same stuff here anyway and also in Castorama in France for 1/10'th the price for the same thing for bricolage (though France naturally more expensive).

So what will you do to make a one-off? I guess the hull you are making will still be a plug, and that you will glass over it in several layers/directions, then maybe vacuum bag? I guess you cannot pull a vacuum with the hull still on bulkheads. So you lay glass and then more resin then have a sanding and fairing party to get it smooth?I hope you will share the process. Sounds a lot easier than making a mold, then vacuum bagging a hull on the mold. I'd like to see the glass thickness as you make the lay-up. I've never done this.

Thx for replies and tips!  yes, the light filler is a bit pricey, but i only needed 3.5 jars at 11$ each.  Yes, one off hull. plenty of sanding and fairing to do.  I use bondo to smooth the hull after a few layers of 5-6oz cloth. It's supposed to represent a metal hull so a few imperfections (aka 'dents') actually add to the realism. I will post pics as build progresses...but mixed up in several other builds as well which delay this whole process....

Received my copper 'L' pipe (seamless tube) today for boiler. 4" horizontal cross tube design using 1.5" flue with 3/8 cross tubes, all 'L' thickness. These are 1 ft sections which will be cut down as needed. Have to calculate the measurements, but should provide enough volume and steam for the mildura...probably a machined bronze steam 'dome' if i'm lazy, or a copper riveted dome (yet to be decided).... I have used 'L' on my other boiler builds and it is plenty thick for this size boiler...


For cutting some of the copper sheet for boiler ends, I plan to try my plasma cutter...will see how that works out!
