Hyd Pump - What did I just buy?

[ihbuilder]

I can get a shaft seal for them , but the specs are for low speed not to mention $$$ . when you dish out leave the area at the shaft in so it goes against the pump housing at the shaft . I was going to do what you did just have the motor stacked on top of the pump using a timing belt and gears/pulley much like verio's setup . I just have my rotary setup for hubs and don't want to take the jig off till the cnc mill is running . I def. got a bad sevo amp now just to get 1 or 2 , 1 for the 4th axis

Actually, Steve that's pretty much what I did...there is only room for two shim washers and the o-ring...that way I add/remove washers to compress/decompress the o-ring. Seems to have worked.

I thought about the vario setup but this was fastest for now...and I didn't have the right belts and pulleys on hand.

Good luck on the mill. If I get a winner on the plate I'll cut one out for you to play with....anything to keep my wheel order moving up the queue. LOL. But no laughing at my tolerances...now that I am making a few precision parts instead of cosmetic I can't believe all the backlash in the little Taig. Some can be tightened and some compensated for in Mach3...just need to stop milling for an hour or two and do the maintenance.
