MADD CATT -41" fantasim saw build

[Chilli]

I was thinking of doing the same, did that much epoxy add much weight?

It probably added a couple ounces but as Cooper said, your dealing with more volume on the Fantasm. You could also try adding a filler to increase volume of the epoxy without a significant increase in weight. With the power we have available today, I doubt the weight penalty will significantly effect performance. But in my case I was running a single with a rudder/strut combo hanging off the extension. So more stress on the pad but with overall less boat weight.

Nice work Cooper!!

Hot water from the tap works well, let it sit for 15 min's.
Don't melt the plastic bottles on the stove!!!

oops ,,I forgot to mention that. As in the picture, on counter not stove, I did just use hot water from the tap.

Thanks to someone on the forum I got some cf from this company. Using 3" cf tape ( not tape,no adhesive-they just call it that) for the side seams and between the sponsons in the front. Then a layer of cf covering everything. There will be other support gussets also. This is just the wet lay up stuff. Not my favorite part but this tape and sewing the seams should help me out with installation.

Installation of another layer of cf. then I installed another layer of cf over the seams on the side all the way into the tip. Still have more to do!

And thanks to Keith (KBB) I have more work! Ha, got one set of motors. Will be able to start on the motor mounts.

Another layer of 1" cf tape in the rudder support area, also reinforcing the seam.

I used craft foam with adhesive backing to make a template. Simply sick and then press the mount, the mounting holes will be embossed.

This is the pipe I used to cut the foam, simply sharpened the inside edge to make it easier to cut. Just press and turn then pick out the hole.

Using a dremmel tool to drill through the fiberglass, as the high speed and sharp point will not chip the gelcoat.

Did you happen to mock those stingers up to see if you can get 0 degrees stinger angle? The 2 sets that I had like that had rear support stands that were a little too tall. I had the stingers mounted as far down as possible and still hade to modify them to work.
If this happens to you, you may be able to mill the stand down a bit. The other option is to fill the hole on the stinger with weld (where the rear support mount is bolted), trim it down, and lower the hole...that's what I did.

I tried to get the stinger as straight as possible. And I was able to get away without having to modify the pedestal to get some positive angle, although I have the option to mill down a bit of the pedestal rod if need be.

I was anticipating having to do that. I figured if I had to there was room to shorten the rod and mill down a bit of the pedestal mount that would be able to easily get another 1/8 " , I think, but it looks like I will be able just keep stock.

Oh those little mounting plates for the stinger support that go on the inside of the hull are going to be a real treat to set! This is like building a ship in a bottle, only you can't look through the glass, you can only look through the bottle neck and have your fingers n tools n light in the way!!! Ohhh and I love having big fingers!!! Lol!!!
