Just to be sure

[peter-curacao]

Probably I'm asking for the obvious but I just wanna be sure
The seam at the red arrows I wanna fill with silvertip thickened with west 406 directly over that I wanna lay a fillet with easy fillet and directly after that I wanna lay the glass tape with silvertip.This shouldn't give any problems will it?

Sounds good to me I had a few spots where the gap was a little wide. To keep it from eating so much epoxy I first filled the gap and voids underneath with some 2 part expanding foam. I think Craig did the same thing. It saves a lot of epoxy, and weight.

Aw, the Lord of Boat Builders is gonna smite me sore, disagreeing with Cracker Larry.
But two part foam in a joint is in like gluing two pieces of plate steel with a strip of styrofoam.
I know "the strength is in the glass" but man, not ALL of it.
Admit though, Larry, have read of your long trip and your boat ain't weak.

Larry thanks I just wasn't sure I could go over the easy fillet directly, the seams I have are okay that's why I re cut the two sheets of ply at the bow section,foam filling isn't an option because except for the bow section the cleats are under there.

Lon I think Larry meant fill hollow space under the sole (if there is) And then clean out the seam with the dremmel or something like that, and then fill the seam with thickened epoxy, so not gluing with foam

Sorry Gents, looks like I provided a solution to a non-existent problem.
For any confused new guys - use wood flour and epoxy the thickness of peanut butter as fillets in joints.

Exactly

I'd suggest 403 instead of 406. You could mix in a small percentage of 406 with the 403 or with wood flour, but straight 406 in epoxy will make a very hard fillet that may be more brittle than with 403 or wood flour. I made some test swipes on plastic wrap with all sorts of blends. Straight 406 was very hard, and very brittle. The 403 and wood flour swipes were somewhat flexible, even with a little 406 added in. But straight 406 would snap instead of any flex at all, after a thorough cure. Just some thoughts for you.

I don't know I used the following chart to make this selection, also I took a dried piece of this mix and I found it very flexible can this have to do with the Silvertip epoxy of choice?

I hope everybody realizes that all those part numbers just describe plain silica, milled fibers, micro-balloons etc. but packaged in expensive boxes.
It cost much more to buy them in a nice box with a label but colloidal silica is colloidal silica.
Micro light is equivalent to our QuickFair except that ours is premixed in resin specially formulated for fairing.

Mixing all those fillers with standard resin will never be as good as the premixed products from the Silver Tip line.
All Silver Tip products use resins specific to the application. The resin in GelMagic is formulated for bonding, the one in EZfillet for filleting etc.
You can't achieve the same performance by mixing filers with standard resin.
Bottom line, if you want top performance, get the Silver Tip stuff.
