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

You want the sole to be thick in foam and spans to be 20" or less. Longer spans require making supports. I made some foam core i beams.. Thanks again Fallguy. I have been holding off for a few weeks before ordering, appreciate your input, I can get started now!! :-) Are there pics of your I be...

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.

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...
