I have been a lapidary since 1978 and over the years I found that building my own machines was one of my best options. I just built my dream studio about three years ago and built nearly every bench in it. Any way I have used the type flat lap I am posting since about 1980, the first lap left a lot to be desired but it did the trick. I have probably built three to date. I put this information on my website but it is in a hidden file so I will just give you all the details here on the forum.

the first image shows the flat lap on my inlay bench.

the second image again shows it on my bench

The third image shows the five pieces it takes to make this lap stand.

The fourth image shows the pre-drilled holes in the top for screws.

The fifth image shows the lap assembled with the motor and shaft.

the next four images show how to cut up your 5 gallon bucket and where to put the drain.

I know I did not do a step by step here but for most this should give you the basics. If you want to see these with a bit more information go to this link and scroll down the page.

Also if you would like to see the studio these machines are in go to this link

All my best .......... Danny

Danny:

I'm like you, I make or repair my tools. I haven't had too much of a choice, too poor to buy the good stuff.

I did manage to get a old 1st generation Graves, and that's what I use for a flat lap. I couldn't afford the laps (this is before the market was flooded with the cheap Chinese ones) so I a got used Corian countertop from my local Habitat for Humanity resale shop and had a friend with a table saw cut me some laps. I charge them with Turtle wax and diamond grit with an agate burnisher and they work pretty well.

I like your lap stand; looks so much more organized than my plastic bags. I now have a table saw, so I have no excuse (except laziness) not to make one.

Thanks for sharing your knowledge. This hobby gets really expensive if you can't be innovative.

This looks really good. My husband has on old motor that I can have so may get him to sort something like this out for me for the larger stones that I can not do on my wheels.
thanks for posting.

What I want to know is how flat a flat lap has to be for basic grinding and polishing of slabs.

I want to make a 16-20" flat lap with no center hole.

Does it really need to be made out of steel, ground to 0.002 tolerances, or will a few layers of a very flat high quality plywood, maybe with an aluminum topper, do the trick?

After all, it's not faceting we're trying to do. Anybody tried this?
