Nice job Greg, showing the process of laying up and bagging your part. It’s nice seeing how other people approach building their own parts. I like the way you roll the resin into the carbon between plastic. Never seen that before but it totally makes sense. It’s the same concept as using resin impregnation rollers. I was starting to panic for you with such a thick layup when you mentioning the heat buildup, but then I remembered its cold there. That thing would have been smoking here, LOL.

Yeah I’ve heard that go around too. Don’t know where it comes from. Look at all the 316 stainless steel fasteners tapped into carbon rigs on pro-built boats. I’ve never had carbon/SS contact issues. On this part there will be paint between the composites and steel pins.
Nice job! I learned a lot today. Did you roll all the fiber and carbon layers in between on the mold before you bagged? Did you have a problem with the epoxy setting up before you finish adding all the layers? Ha, ha, I saw Delos and Calico boats there at the end of October in the boatyard, looks like there was not much progress since then.
Yes, all those layers get heavy roller pressure down on the wet-out table before being placed on the part. I don't worry about rolling after placement because the vacuum will remove any air bubbles. I've had plenty of practice with lots of layers and controlling for the hardener taking effect. The air temp was down in the low 60's that day so I was confident I'd get away with the 11 layers if I worked quickly, even with 205 Fast hardener :) It never got hot or gelled - in fact the whole thing needed heat lamps once I got the bag drawn down. Bill & Grace on Calico Skies and Line & Teal on Basic were busy on their boats when I was in town. Delos crew was in Europe. I imagine many boats will have launched before me this go-round.
A master class in fabrication technique.
Wow, you are very skilled !!! I would like to learn all that
Nice job, Greg! Judy

Thanks for the details - always something to learn seeing how someone else does it. Happy New Year!
Excellent!
Did you isolate the carbon fiber from the metal pin? I understand when the two are in contact you get electrolysis between them.
