Thanks Dallen, I have looked around for stock UJs to use for this shaft but they were just too expensive in the size required. The bore needs to be 5/8", stock industrial UJs in that size (or large enough to be bored to that size) run close to $200 each, more than that from some suppliers. It was a few months back that I spent quite a few hours internet shopping and making phone calls to several different suppliers, it led me to the conclusion that I am going to have to cobble something together myself. I'd rather spend several hours (who am I kidding it will be several days) manufacturing them myself rather than spend a quarter of the cost of my mill to buy a component.
I haven't seen that list at Zoro before, cheaper than I found but even there it is $98 each in this size, which translates to about AU$130 each, plus shipping, at the current abysmal exchange rate- plenty expensive enough to encourage me to use my machinery to make my own. Reckon I need the practice anyway. I'd prefer to keep my money for things I can't make.
Of course, an ideal solution would be to find someone wrecking (or 'parting out') a mill of the same model with a good driveshaft, but I came up empty handed after a multi-nation search on that one too.
Edit: almost forgot, another problem I came across when searching industrial UJ specifications was that the maximum angle on most of them was significantly less than what I need, this shaft runs about 42degrees at each UJ when at the upper and lower limits of knee travel, it's very difficult to find a UJ that specifies more than about 30-35 degrees max angle. The Lovejoys joint in my size from Zoro specifies 25 degree max.
