Hi Bernie...
The passes are pretty fast. That piece is about 6" long and if I had to guess, a full pass (going from L->R then R->L) is 5 seconds. To cover the part from top to bottom (on one side) is about 5 minutes. I'm sure You Tube has some live videos.
On a lathe, you don't do much at all. With this thing, your left arm is cranking back and forth like an organ grinder's monkey and every five seconds, the right hand makes a quarter turn on the infeed. You can easily fall into the trap of locking your body into a hunched-over and set position for a long period and before you know it, your shoulders are tight and stiff and lower back is aching.
BTW: I really should mention that full face protection could save your vision or life. I highly recommend wearing it.
... Good luck with your machine. What kind and size? BTW, if ever I had to get a different one, a 6x12 instead of a 6x18 would suit me fine... Autofeed... yeah, I'd love that.

Yes, I never really notice much airblown dust on other machines nor does it build-up on my eyeglasses (unlike with my sand blaster). The trick is to get the draw tube lined-up right on with the direction of the projecting dust.

I love this thread Ray!! Thank you! This lesson is right up my alley, since I am in the market for a Surface grinder, and think I found one.
How long do you take on each pass? Silly question, but I've never seen it done. What is tiring about it compared to lathe work? Is it that fine a feed per turn? The machine I'm looking at is also manual (or I couldn't afford it
