I'm looking at getting a used Brown & Sharp 618 Micromaster. One of the units I saw has the hydraulic table feed but the elevating handwheel jerks quite a bit when you are trying to do fine movements. Also the fine adjustment knob is stiff to the point to where you can bairly move it.
The other unit I was looking at didn't have that issue but didn't have the hydraulic feed.
I'm wondering what would cause the elevator wheel to jerk with slight movements. I'm hoping the fine feed worm gear needs to be taken out and cleaned but it might be binding up on metal. I tried test grinding a part and it was very annoying to do the fine movement you would expect when grinding. I could probably live without the hydraulic table feed but I feel if you are getting a grinder and you can get it, you probably will kick your self in the butt later for not getting it.
