Also be aware that it is a toxic process, when the cutting dust is airborne...
The resin is still heavy, and fiberglass can be used instead... One has to be careful while setting as there is is a chance items can set slightly warped, and then there's building the molds and jigs...
Cutting some woods or metals to make parts is at least a direct process...

I bought some CF tube not long ago from a UK specialist supplier. I needed a precise external diameter and they had to measure the tubing in stock to find precisely what I needed. They told me that because tubing is made by wrapping CF around a former, the thickness and thus the external diameter varies within a tolerance. This makes tubular parts less than ideal in size so they would potentially need sourcing from somewhere willing to measure them or machined to fit. Not an ideal solution.
Not trying to derail the thread but I'm pretty excited about machined Dupont Delrin.
pkg: My former employer was one of the few (maybe the only one) that offered an undergraduate engineering degree in composite materials technology, and an asssociate was deeply involved in their large research and manufacturing facility. Making CF tubing exactly right is not that big a deal. We did not call it 'tolerance', but 'allowance'; maybe another British vs American thing?

The Walker Titan is ABS, right?

Interesting. Perhaps its more a thing about buying small quantities cheaply. Most of the stuff readily available is advertised as either 1" or 25mm over here but its perfectly possible that its usually one and the same - hence why a specific request suddenly gets the right size. Moral is to check that what you are buying is as described I guess.Originally Posted by Jac@stafford.net

Isn't Mike still producing his cameras? I don't think that the wide version is available any longer but I assume his others are?
Yes.
We were the Rimowa luggage distributor in the US for several years. Rimowa invented the aluminum suitcase and then was a pioneer of ABS luggage before they invented polycarbonate luggage.
The problem with ABS is that it could crack. Aluminum and polycarbonate do not.
I recommend the Feisol tripods. I've had one for over three years, and it's been great. Reasonably priced and beefy, much more beefy than others that offer a spindly tripod at a high price.
See link at http://www.feisol.net/
I have the 3372, and if had had the choice at the time, I would have selected the 3372L (L for longer.) For a more compact tripod, they offer the 3472, which has a four section legs. The 3472 is also made to accept a leveling base, though one can have the flat base as well.
All of these tripods have 37mm diameter upper tripod leg sections. As I said, beefy. The stage at the top of these tripods is machined, versus cast. Stronger, and it weighs less. At 3.86 lbs, my tripod legs weigh less than my tripod head.
The SF is gone. The XL Wides are still offered.
But I think we're getting way off-topic here - this is the DIY subforum, and unless I've misread him, the OP was asking about carbon fiber as a material to work with in DIY camera-building, not for recommendations of carbon fiber cameras or tripods to buy.
I've used my Feisol 3371 for nearly 8 years, and although it would benefit from a service, it's still a very competent tripod.
Not simply carbon tubes though, as they have internal grooves to stop the inner legs turning while tightening the collars.
Mike
