First my machines are in general a pet project, I like to modify things even when it’s not financially Beneficial, we all spend money on hobby’s of some kind, mine is to over complicate things and I enjoy it! (I must have some German in me)
I’m looking at a few different DC motors for my SB16 as I want variable speed AND power.
Im looking at 1hp and 2hp motors @ 12-24-90-180v 3600 rpm.
I’m leaning towards a 2hp 90v DC 3600rpm.
I want a high speed/ higher hp dc to make up for the power loss at lower spindle/motor rpm, I am keeping the flat belt setup (of course) but I’m gonna go with a wide synthetic belt.
I hope to see my top spindle speed up around 1500rpm while maintaining more then 1HP in the low speed.
I’ll still be able to utilize the back gearing for “crawl mode”.
I currently have a tachometer and I’m a hobby guy so the lathe doesn’t see more then a few hours a day/ few days a week of use, I’m not worried about shortening the lathes lifespan (within reason) as I’ll eventually upgrade to another lathe in the future.
Any suggestions on the motor (voltage/speed etc?) and controller?
Now heres the crazy side thought, pressurized oil system to the headstock bearings. This is still just a thought in its Infancy but I have played with low pressure displacement pumps. Anyone ever seen it done?
