"Thanks everyone. I got a set of 1000 lb. springs that fit after quite a bit of searching. Looking forward to posting some reports once I get this rig on the road and the boat in the water. "

"JC, Go with the 1000 # springs. The heavier springs will beat the heck out of your DB. I used 1000# on my trailer an it rides very smooth behind the car. Phil"

"Yep, if you can find 750s I’d go with those. But 1000 lbers seem to work well"

"Thanks, and I just found Bennett posted on the same issue many months ago."

"In my trailer hauling experience the closer the spring rate matches the load the less shock transmitted to the load. Here is a spring rate calculator that might help you modify your springs to work correctly. https://www.suspensionmaxx.com I found…"

"Try using the Coat It instead, its a little stronger with kevlar mixed added"

"JC, Be careful in how much you add to the epoxy, too much will make the epoxy brittle.  I had this problem and had to remove a couple layers of epoxy with graphite and the went back and added several more.  Here's West Systems…"

"Also consider that powdered graphite may make it more difficult to adhere a future patch or repair."

"Thanks Bennett. It is very encouraging to know the final result works that well. Realized I had a brain cramp, never thinking to look at my vendor (Raka) for guidance. Their website says a tablespoon per 4 oz of epoxy."

"Hey Jc, I ended up having to do something like 8 fill coats on my 20 oz triaxial bottom because I was putting it on way too thin. I can't remember the figure, but I put way more powder in the mix than was recommended simply because it…"

"It’s not.  But it is important that you do it before installing the bottom."

"Sounds like predrilling is not really critical. "

"JC, If you need help getting a system I can get you one. Mike"

"I did mine dead center/maybe a 1/4 inch high.  For reference, I have a Regal pedal mounted on 1/2 thick board.  Everything lines up perfect.  I did wait until the frames were installed to drill my holes though so I could pull a rope…"

"This is the best advice. For a hand layup, you want a 1:1 ratio. Weigh the glass you plan to layup.. add the same total weight of mixed resin. You won’t waste resin this way or buy too much or too little"

"When I was building my boat, I was told that for 10 oz of cloth, I'd need 10 oz of resin. So if the bottom of a 16' boat uses 4 yards of 22 oz cloth - total 88 oz - I'd need 88 oz of resin+hardener. Hope that helps. "
