DIY Surface grinder

[Colin Barron]

The coolant/grinding wheel/ground metal, produces a very fine grinding paste so if wipers did work it would not be for long.
This is the minimum spec machine in terms of safety and ability to grind. It may be cheaper to buy a complete machine that needs a rebuild and fit motors on the handwheels. I paid 250 for mine and magnetic chucks on there own will not cost much less.

Colin, I don't think you quite understand what is going on.
I don't actually need a surface grinder.
I want to play with a surface grinder.
Making it to my own design is merely the icing on the cake.
I do this for fun

Motor fits on okay. No vibes when it hangs from the screw, gentle vibes when I prop it. Weird.

Now waiting for the 20mm rail which is the grinder shaft, the 30mmx2 nuts and left hand die for securing the stone, the stepper motors/drivers etc., and the time to fit it all together.

What clearance bearings are you using?

[Robin Hewitt]

No idea. Do you think it matters? I will be running them in an oil bath.

No idea. Do you think it matters? I will be giving Quick Extender Pro a shot and running them in an oil bath.

Are you expecting issues when you get to fitting it all together?

[Robin Hewitt]

Assembly is easy.
I am expecting 'issues' when I grind my first, large, flat surfaces and then put them face to face with a smear of engineer's blue.
Question is, will I be able to correct it?
It is not easy to get your head around a lack of flatness and see through it to a probable cause and solution.
I will either succeed or become bored and do something else
