chris......one good trick i learned....before sanding is to put a thin layer of spackel over the entire hull...then coat inside the hull with resin or epoxy the spackel keeps the resin from seeping out side the hull this also locks the planks so they won't shift on you when your sanding. :thumbs_up_1:

....joe.....btw hulls looking exelent.....

Thanks Joe! Let's say I was looking into epoxy... What's the best epoxy to buy that will hold up for this purpose? I mean, I know there are some model rocket guys that are using this stuff:

What do you think?

Hi Chris A superbly crafted plank on frame hull . Question what type of adhesive do you use to bond the planks? I've always used a resin based wood glue called Cascamite now produced in the UK by Humbrol. The blurb says it's stronger that the material that it's bonding!
Dave Wooley :thumbs_up_1:

Wow Dave, Thank you so much! Well, Ive never tried to attack anything quite like this before. So, prior to construction I did several adhesive tests using every kind of glue I could get at the hardware store. I then took these test panels and abused them severely. No kiddin', I threw these things around the shop, twisted them, pried on them and even whacked them with various blunt objects. The neighbors probably thought I was mad! :heh:

The ONLY one to hold up, and to my surprise was the one built with plain old "Super Glue". Don't get me wrong it DID break but the super glue never separated, the wood broke away from it. I was sold.

So, long story short, it's all held together with super glue. And I figured since I'm going to apply a coating over the entire hull that it should hold up just fine. Although, I have to tell you... I have always been guilty of over engineering things.

hi ccain,
your hull looks fantastic, i've never built a hull from scratch before but want to give it a go when my other projects are done, so trying to gather as much info as possible, am i correct in thinking this is just a plug for a fibreglass hull or will this be the actual hull?
many thanks
leigh :thumbs_up_1:

Hi Trig...
Nope, not a plug. She's gonna get a coating (to be determined later) and this hull will be used as the actual hull for the build. Good luck with your build!

I worked out the hull mounted sonars today...

exelent work on the domes chris.....what kind of wood are you using both the domes and planking??.....joe

Hey Joe... I'm using clear white pine for the carvings and I used honey pine which I milled at my father-in-laws shop.
I like it. It's light, flexible and sands really easily.

I finished up the stern this evening as well.

I think I got the domes close...

have you decided on the covering??.....joe

have you decided on the covering??.....joe

No... Not yet. I'm still researching.

I took a break from my hull covering research to rough out the 5"/54 caliber Mark 42 gun. It needs a ton of sanding yet. I'm gonna try my hand at this resin casting thing... That is, once I get the supplies. After I cast them I'll hit them hard with details. I made the gun barrel with a pin on the back that fits into the guns structure. I figure this would make it easier the cast.

so ya going to start casting fittings heh??? here's my source http://www.silpak.com i use this because there spitting distance from me.......joe

Well... I ordered up the resin that I will be using on the hull. So, while I'm waiting on that to come, I decided to press forward with the build and continue to rough out more components.

Here's the single Tartar...

exelent.....awsome.....looking good chris.. :thumbs_up_1:

MAX CLR-HP A/B is a two-part epoxy based system specially formulated as High Performance version of the MAX CLR resin system.It offers higher mechanical performance while maintaining crystal clarity, gloss and other aesthetic qualities. MAX CLR-HP provides excellent performance at wider service temperature range, especially its retention of its mechanical hardness at elevated temperatures as well its durability when exposed to below freezing temperatures. Its none blushing performance, high gloss finish, excellent transparent clarity, color stability and ease of use make MAX CLR-HP an excellent choice as an impregnating resin for composite fabrics, protective coatings, casting resin and general fabricating applications.

Thanks Joe.

I'm getting the casting resin and mold making supplies from Silpak. :thumbs_up_1:

But... For the hull, I went with Max Clr. It's out of Ontario CA and I found it on that pig-latin auction site. I couldn't beat the price. :heh:

I'm going to be coating inside and outside of the hull as well as using fiberglass mat and cloth for added rigidity.

I wanted something strong enough to take a little abuse. Here's the particulars:

Got a little more done to the Tartar...

Here's my missile lathe :big_grin:

Added a few details... I think I'm gonna hang it up for the night.

Well... What good is a ship without her Captain?

I'm probably not going to use him on the deck or anything. I just had a little time to kill after dinner and... Well.

Ladies and Gentlemen, I present... Captain Woody. (My stepson named him :big_grin:

)

Hmmm... The ship must be dry-docked in Mississippi.

OK... So, I know I said I was gonna cast another mount, but I had the stuff and I decided to just go ahead and make another one. I also threw a coat of primer on the first one. I may end up casting the better of the two, then again maybe not. But I am gonna give this casting thing a try. But that will be down the road a bit.
