Transom Help Needed - 1975 Tri hull

Re: Transom Help Needed - 1975 Tri hull

Ok, hopefully this pic will help a little better.

Washers and cotter pin on one board, a nut is countersunk and epoxied in the edge of the other board. To use the clamp you tighten the lower bolt until it is snug on the top of the transom then Loosen the top bolt to put pressure on the lower section of the transom. Once they are about equal then use equal amounts of turns to keep the pressure uniform. Practice makes perfect.

I think i got it now. I sandwiched a 2x4 scrap at the top and only tightened the bottom bolt, it snugged up just fine. O fcourse I will be installing 5 or six of them across the core when it is set in place. Thanks for the help.

WOG - read your post after I posted. I used a nut in place of the cotter pin and used the wedge in place of the epoxy and countersinking. Do you think my system is risky or deficient?

Peanut Butter Question

Better to use 1/4 Milled Fiber or 1/4 Chopped Strand for the bonding of the transom core to the hull? What about Fillet material?

You can use the wedge but it would give you the ability to adjust the pressure as equally IMHO. For PB use 1 qt resin, 1 1/2" qt Cabosil & 1/4 cup 1/4" Chopped Strand fibers. You can cut up scrap pieces of mat and make your own if you have some scraps.

Re: Transom Help Needed - 1975 Tri hull

Ok. I have the transom core all glassed up and sanded down. The hull has been prepped and cleaned. The clamps have been cut, adjusted, and dryfit. I am about ready to make up my peanut butter. I know you said it would take about 3 qt of PB. Is that 3 qt's to coat the one side of the core and one side of the hull? Or is that 1 qt for fillet material, 1 qt for hull side of transom and 1 qt for opposite side of the core. My transom measures about 24 " high and 55"wide. I am thinking it is 3 qt's on the core to hull side alone but don't want to make up a bunch of PB and let it waste. I also don't want to under produce and have it start to kick off before I can get the core mounted and clamped.

Figured I better ask the question now
