IF you are very worried about corrosion between carbon and aluminum you can use hysol as the bonding agent for your hardware.

Skipper Eh? That's pretty interesting work, Hans. Bet you have a story or two.

Yepp, before wife & kids I took a sabattical and started doing sailing yacht delivery trips (I had been a part-time instructor before...). Initially I had planned doing that about six months, but it was so much fun I stuck with it for two years. Indeed, a lot of stories could be told, but this is hardly the platform for it. Perhaps, one day, over a beer or two (a 'Duvel', or 'Kriek Lambiek'...?)

cheers!

Ha ha, I thought so Hans. There are a few members here who know the difference between a sheepshank and a Spanish wench, lol. I suspect that if several of us got together over drinks there'd be a lot of laughs. And maybe calls for bail. ;D

Jeff Great video,

I actually just use aircraft safety wire for hot wire cutting operations. It doesn't stretch when heated so you can really tension the bow to get sag free cuts. Plus I have it laying around hanger. As for my power supply for my hot wire cutter I recycled an old 1000 watt microwave i got for free into a variable power supply. I can run all sorts of lengths of wire and then modify the output of the power supply by turning a knob to set the heat of the wire at the best setting.

When you get your female molds done and you feel like being adventurous I have vacuum pump setup for composites, let me know if you want to give that a try. Parts are so much better after vacuum bagging, lighter, stiffer, stronger and a better finish.

[Schmleff]

Thanks for the offer. I actually bagged the cores. I agree, bagging is Nice. I laid the tips up wet for the last pair. I use peel ply on wet layups for nearly the same effect.

[oahupilot]

Well, peel ply alone wont give you the same fiber consolidation as vacuum bagging or fiber to resin volume fraction.

Thanks for taking the time, Jeff (and to your cameraman).

Indeed. After the peel ply, I use paper towel and wick as much excess resin from the layup as I can. I did not have the pump for bagging at the time.

Thank you for that video. You make this look easy!

Thanks Jeff. The video had a lot of good information. Will their be any more videos in the series? Thanks again Bigred
