What CF sheet to use for 1/8 buggy chassis????

[PBO]

You need a pump not a vacuum cleaner, you'll burn the vacuum out in a few hours

Have a look at this link http://www.instructables.com/id/Vacuum-bagging-basics./ kind of how we do things (I work with boats) but the lamination/prepreg is relatively easy, getting the vacuum pump system working properly can be a bit fiddly for the first time

that looks an aful lot like using a "foodsaver" vac sealing thingy...

A real vacuum pump WILL out perform the Foodsaver. The Foodsaver just works really well for the money. Besides, I think PBO was just responding to your idea of those storage bags that you vacuum (with a Hoover) the air out of.

what about a"hybred" chassis???? alloy front part with kickup and CF the rest of the way. think old RC10 cars

[pb4ugo]

That would work. Mill both the CF and the aluminum to 1/2 thickness (or bend the aluminum to accept the CF in the bend--ship-lap style) and use some Scotch Weld 2216 at the joint. Make the joint under the steering posts so it's clamped together as well.

Kind of makes you see why the RC10 Graphite had the kick-up molded in

i thought about that days ago... if you can't bend carbon fiber, use aluminum!
I´m planning on doing a cf chassis for my d8, but the front part it´s bent upwards, so why not use both???

That is basically what MR comstructor does with some of his chassis . But it just looks so much better when it's all one piece.

bringing this thread back up...


whats the best way to cut CF???

I have access too
dremal: mabey the multisaw atachment, or carbide bit??
hacksaw: blades??
bandsaw: IDK if the teeth will last
CNC router: only has 1/2in collet and bits are $$$$$$
mabet a CNC mill too


my personal thought was the dremal multisaw attachment, and a realy fine blade....

[pb4ugo]

The cnc router with a diamond bit designed for fiberglass would be the ultimate. Whatever method you choose (and they'll all work about the same, other than the cnc) make sure you wear proper breathing protection. Carbon dust is NASTY stuff.

I used a band saw with a fine tooth blade and it worked awesome.

[whitrzac]

the problem with the band saw is, its in the "wood" shop part of the teched lab, and blades are $45 each. would there be any problems with it geting into the dust colector??

any links to a router bit?

Here's a 1/4" one: http://cgi.ebay.com/J-L-TOOLS-1-4-FI...#ht_2325wt_941

Spend a couple minutes on google and you'll be able to find 1/8" bits too.
