Mike,

Looks cool... I'm still waiting for my order from ACP-composites. Questions - What is the putty made from? Under the cowl plug, is that the breather sheet???

Can't wait to see the final product...

Mark..

OBnut, If I remember right from his Kevlar 12 rigger post, it is regular epoxy mixed with graphite. it give it a really hard tooling surface. there might be something else in it though. :-

 

[MikeP]

The putty is epoxy, graphite powder, silica.

The sheet between the glass and the plug is a piece of mylar. The mylar makes it much eaiser to lift the mold off the glass, a project this big would be difficult to pull off the glass.

When I make the sheets on glass I can scrape up a corner with a razor and peel it off the glass. A rigid mold like this has no flex and want's to come off all at once.

I didn't use any breather cloth this time.

Rats, knew it would be something I don't have.. Well, guess I need to order more WS epoxy anyway, I'll just add some graphite powder in the order. I've got silica on it's way...

Found this comment in CST Sales site: " If the finished part will be a dark color and exposed to direct sun, consider stepping up to the Pro-Set or MGS Epoxies. " Since this is a comment about W.S. epoxy, any concerns here??

Mark...

Nice thing about buying graphite powder and silica is the smallest amount you can buy will be a lifetime supply.

I don't know about the dark color and UV thing. I know UV is bad and I keep mine out of the sun when not in use.

I polished the mold with 400 then 600, waxed it up with mold release. It's ready to use. I am going to try the first one with kevlar and no vacume bag. If it doesn't work out I will have to cut the back out of the mold and build a wood frame to support it.

-MikeP

??? what no vacume bag how will that ever work ???

 

[MikeP]

Well swing and a miss :'( got a big mess.

Try again in the morning.

Ummm well did I mention the sponsons turned out ok? Lets go take some picture of those.

 

[MikeP]

Ok, back to the cowl. I think this will work out.

 

[wswatzell]

Mike, those Sponsons look great!! are you vac-bagging the cowl this time?

 

[MikeP]

;D ;D ;D I got my first CF part without a vacume bag.

 

[wswatzell]

WOW!!! THAT LOOKS WAY COOL!! Is it heaver since you didn't use a vac-bag?

 

[Slideblues]

CF cowl and sponsons with a Kevlar center section sounds KEWL ta me, Nice job

I take it the kevlar cowl didnt work well without the bagging?

Gene ;D

 

[MikeP]

Thanks Wade

I think the weight without bagging is about the same, maybe even a bit lighter I laid it up pretty dry. The bad thing is the inside of the cowl is rough. I like the finish of the peel ply and vacume bag much better but I saved time and money by not bagging. I also really wanted to learn how to lay up a mold with out the bag.

Thanks Gene

I didn't use kevlar because it's too hard to cut, I had trouble laying up the cowl with one piece. I ended up using 3 pieces for 1 layer. That would of been 6 total. The pieces needed to have perfect cuts so the edges wouldn't look bad in the finish. I can't cut kevlar with clean edges.

CF really cuts nice with a rotary cutter.

I need some stickers and a driver, ya a really good driver one that will fit in the canopy and can hug the bouys without hitting them.

-MikeP

 

[wswatzell]

I Think that Stewart Little is your man...... um mouse .

He should fit under the canopy, he has proven his ability to drive rc boats, & he can hug the buoys very well!!! ;D

LOL!!

 

[MikeP]

I don't think bullet proof fits anymore has more CF than Kevlar.

Any new names come to mind?

Stewart Little? He seems to always be in trouble.

 

[TimD]

SR-71 Blackbird!

 

[CySlyde]

Drivers....

hmm stuart is a trouble maker but he always seems to save the day

what about his bud good old steamboat willy he could use the upgraded equipment plus he kinda matches

Bart Simpson..... the yellow and black theme seems to be in with ricers around here and our non-member member Dale has got homer... that'd be a cool race to see.
