Tim said:Pulled the trigger with David over at Voodoo Vintage. I have the leftover bits for another XS650, and this is the one style of bike I don't have and always wanted. The frame is being built. In the long run it's better and actually legal/insurable as compared to a hard-tail mod on an XS650 frame. Some of the extra cost of the full frame vs the hard tail will be recouped when I sell the stock XS frame.
Tim, have worked out what you are going to do about a top motor mount or are not going to bother?
It is a lovely frame and if I can can justify paying the import charges etc I suspect there will be one flying over to the UK later this year.
You should look into infusion, I am working on getting everything for use at home. I do it at school now, so far I have release film, bagging materiel and 2 rolls of glass fiber continuous mat and woven.
It will give you a 70% fiber and 30% resin, plus it is a lot less messy and you get a lot better quality of part.

This is a whole new adventure for me so I'm starting off with the basics as I'm used to making parts out of traditional fibreglass products, but I'm guessing being able to make things in CF is going to snare me and I'll end up wanting to try the other more spohisticated processes LOL

You can lay cf up just like glass of the same weave pattern. Each has it's own 'personality' that you have to pay attention to but the differences are minor from a lay up standpoint. Be sure to tape the edges you plan to precut as it'll unravel at the edges quicker than glass and use SHARP sheers to cut.
Go to it mate, I'll be watching to see what you come up with!

I've been looking at this fabric because it claims to make cutting sharp edges a lot easier

Not sure how prices compare with the USA?

I've only done vac bagging with lay-ups that i hand applied the resin.
I've seen video of infusion setup where the material is laid on the mold or buck, vacuum is applied and the resin is piped in, so similar just different application methodology. I'm no expert though and I'd bet there are others who can say difinitively
Swagger, I agree.
Both are vacuum bagged. One applies resin to the mat and then bag it and appliy vacuum to squeeze out excess resin. Infusion allows resin to be sucked in by that vacuum to a dry lay up, so only the right amount is admitted in the first place. Should be less wast that way and a stronger part
At least I think that's the difference.

This is probably the best way to explain it, if you have any questions feel free to ask. I made an 3"x12"x.04" I-beam that held up to 1700lbs before it failed. I think this is going to be the future in composites, Boeing is already trying to get away from expensive autoclaves and pre-pregs (freezers). This is what I think will be pushed hard in the future. I am designing some tanks now that I will be infusing.
And it really isn't any stronger than hand lay up, it is just has a better strength to weight ratio. Thicker is always stiffer in composites. But if you have two carbon piece that are .1", one infusion (70% fabric, 30% resin) and one hand lay up piece with a vacuum bag (40% fabric, 60%resin) the part with more fabric will be stronger because the resin really has no strength.

And strength really comes from the shape rather than brute force thickness. Think strength of a tube versus a solid rod and the relative weight. large diameter thin wall is stronger than small diameter thick wall of teh same or greater weight (slight oversimplification of course)
