for hose I use 1/16" ID 3/16" OD silicone tubing which obviously has a 1/16" wall thickness. this hose looks a bit more beefy than something that only has a 1/32" wall thickness but it's much more durable and crush/kink resistant which makes a big difference for something like the O&A design and it holds onto pins much tighter than a 2mm ID hose in general. FYI 1/16" is ~=1.6mm, 2mm does also work in most cases but I usually just stick to the 1/16" I'm used to and have been using for years... amazon has some good hose but the best I've found is through McMaster Carr
ok so ray says he would be down for a black delrin O&A, skillzizzo I'm guessing would be fine with black also?... actually I've been playing around with delrin a bit past few weeks in a DNA75 and I've discovered that I really like the white with amber ultem combo, just want to show that here to consider as a possibility to maybe be considered instead of black?
if I do decide to order a 1 1/4" slab of delrin it will have to be just one at his point, either black or white... just wanted to throw the thought of white out there for consideration
it also looks really sweet in an all white body/door with a black ultem faceplate too. I built one of those too, I'll show pics of that one later but to me personally theres just something I really love about this white/amber combo, I think it's gonna look really nice when all finished with an amber top cap 
the white also works really well when paired with a stab wood door and chip cover
personally I'd rather do white but if the very few who would even consider an O&A delrin mod would prefer black then I would just go with that...
