Re: TX18 Foam core stringers, ribs and sole. Strakes.

Corelite 450 is fine for a transom. Two pieces with a 1mm pb epoxy bond done at about 2-4psi bond pressure. Wet both sides with thickened epoxy using a 1/16" or 1/2mm vee trowel. The schedule is up to JM. Something in the neighborhood of 5 or 6 layers of db 1700 each side with wraps over the t...

Re: TX18 Foam core stringers, ribs and sole. Strakes.

I am glad to hear that you like your TX18 but can we have a performance report and some pictures? Some of your questions are easy to answer, others not. Let's start with the easy ones. Scale by 7%: no problem at all. Raise the sides 4 to 6" easy, you can do that. BTW, we can talk metric, 10 to...

Re: TX18 Foam core stringers, ribs and sole. Strakes.

Hi WP, thanks for the advise and compliments. We travel on extremely bad roads here so we make the trailer bunks as long as possible. I actually built the trailer upside down on the inverted hull before painting. By doing it this way it was much easier to get the bunks to follow the contour of the h...

Re: TX18 Foam core stringers, ribs and sole. Strakes.

Sorry missed the height settings question. I made a 3 inch jackplate and we ended up with the cavitation plate set just below (10mm) the bottom of the hull and a standard factory aluminium prop. Out here we have limitted access to props, hydraulic jackplates etc. She turns well at speed. For this ne...

Re: TX18 Foam core stringers, ribs and sole. Strakes.

Hi Jacques, Thanks very much for the indepth reply. I'll go through my pics and post them, and I think I have a video or 2. The build was eventually done out of commercial pine plywood, of extremely low quality as thats all we could get at the time. As I had never worked with wood, or glass before I...

So.. here goes. History: A couple of years ago I placed a question about building a TX 18 using foam core, with th...

Re: Can the TX18 be built with PVC foam Core?

Thanks topwater, because of where we are based and the questionable quality of any wood / ply, as well as the costs and logistics, we would ideally like to go the foam core route. I did think the weights might be heavier than the ply version, but this is not a concern at this time. Hopefully when Ja...

Re: Can the TX18 be built with PVC foam Core?

Thanks for the great input Fallguy. As I have been delaying so long glassing my TX18, the initial thought was to use my hull on its jig as an internal mold and lay the foam over it. Alot of time has passed, and I have added rub rails to my hull, so that idea is out the window. The next idea would be...
