The nice thing about the double angular bearing, unlike your average single angular bearing, is that it comes with rubber seals. Pop the top one out and add oil, something like Castrol GTX would do nicely, and I don't think you will have a moments worry with it.

I eventually went for stretching the shaft between two singles with Belleville washers. I have become a big fan of Bellevilles since I started aiming for truly zero backlash on everything. A thrower ring on the base to keep the crut out and not overly generous with the oil.

I ran it up to 6000rpm then started winding the speed up on the digi phase controller. I was heading for 12,000 but started worrying about the belt driving it, felt pity in my heart. Probably be okay, but you do need a noise level that everyone in the shop can live with for those long cuts :whistling:
