Flat Lap

Postby jim burchett » Tue Nov 24, 2020 5:22 pm

I have recently seen several small 25cm potter's wheels for sale recently cheap,. Thinking these could easily bevrepurposed into a flat lap. Anyone have experience with this? Thanks.

I saw those advertisements as well and thought the same as you. I know of people in the past that have used larger ceramic throwing wheels as lap wheels after converting them. the magnetic diamond discs might be a challenge to use on these as I think the top surface is aluminum so it would require some customization with a steel top surface. Go for it and let us know how it works out.

Arrowmont in Tennessee had a potter's wheel that had been converted to a lap wheel. They had an iron disk laminated on top of the aluminum surface. Worked fine last time I was there, several years ago.

I have thought about this too. I assume that the RPM of the pottery wheels is slower than that of the flat lap grinders. Does that make a significant difference?

Tom Furman, I ordered 1 too I was thinking that some small powerful magnets silicone to the aluminum might be enough for a steel diamond disc. What were your thoughts on a usablevdisc?

You might try applying a ferrous sheet to the aluminum base disc for the magnetic grinding discs to stick to. I found a site for the ferrous sheet material. It is: https://us.first4magnets.com/ferrous-ma ... tapes-t174

Really good double faced tape will hold a steel disc on the aluminum. We used to use the tape to hold things down when we were doing milling on a good sized milling machine and it held. It might be worth a try to use some waterproof Gorilla glue or some good silicone.
I'm just hoping that one of these will appear at my doorstep some time. Apparently shipping from Wufeng province China. Anyway, paid with Paypal so $ should be safe if it never shows up.
