"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. "

"I use 20 oz. triax on the bottom of my boats and it takes a little over 1 gal of West resin using 207 hardener which is 3-1 ratio. 2-1 ratio epoxy will go a bit farther. Can't help you with the sides as I rarely glass the sides of boats with…"

"Thanks, I thought two layers of 10 oz, one at a 45 degree bias to the other might be easier for me to apply."

"You may want to re-evaluate the need for 22 oz triax. You will be using a lot of epoxy for just that. It is probably over kill not to mention costly. Consider 2 coats of 6 oz glass. Just a suggestion based on experience."

"Then you should be very happy with this. Sometimes when I was pouring small quantities of epoxy, 20 or 30 grams for example it was easy to add a gram or two too much. Then I found it handy to have the corresponding amount of epoxy figured out so I…"

"Thanks Rick, anything quantitative makes feel much more confident!"

"Here is a method from Epoxyworks: https://epoxyworks.com/index.php/estimating-epoxy-amounts/ Basically you need to figure out how many cubic inches of epoxy is required. When you mix up epoxy you can also figure out the cubic inches for that piece…"

"yeah its mounted to a bracket that is squeezed between the frames and bolted. Nothing moves but the anchor rope"

"Bennett, I suspect the underside of your bracket is not in contact with the floor of the boat. Is this correct? I would think otherwise there would be movement and wear om the bottom in a critical location."

"I bolted the release to a homemade wood bracket then bolted it to the frames.  Just #10 bolts (3/16) I had left over from the gunnels"

"Dierks will bend you and mount for the foot release that fits between the frames if you give them the distance.  "
