Thanks again Daniel! I'll have to look into them.
As for the ACME screws, I got them on US eBay. There's a store on there called Precision CNC Router who have 2 types of screw in a few lengths, machined on the ends for 5/8" bearings and a 1/4" part for the coupler. However I'll be machining those down a bit more so I can put locknuts on the bearings and to get them the right length. They were quite cheap too, they combine shipping and do custom orders too (they sell them with Delrin nuts, but you can request they ship without them). |
