Patrick WallinWhat is it? Little micrometer with adjustable table
I recently was given a little table mm micrometer. It has an adjustable table on it that I have never seen before. It was a basket case and I now have it assembled and it is accurate. I also received a American Webster & Whitcomb lathe (with all the collets) that was frozen and I now have it working great. It came with an attachment that I do not know what it is.
Also if anyone has a booklet on the lathe would you let me know.
Thanks

That's a Crocker jig for stoning gravers. The graver is clamped in the part with the multiple adjustments, and the "T" rides on the bench, giving a fixed angle to sharpen the graver.

Patrick WallinNow that you mention it, thats exactly what it is. I could see it as I was reading your explanation. What is used to hold the jig or how is it mounted?
I'm still baffled by the little table on the micrometer.
Thanks Bob.

Jim BielefeldtNice micrometer. I couldnt think of a use for one before I got mine. Now I cant understand what took me so long to get one. Its a great tool to have when doing balance staffs as a lot of them can be in the wrong wrapper/bottle when you get them.
That table looks like it will be helpful for holding things to be measured while you are doing it. Like when measuring a shaft on a gear. Wish mine was like that.

Bob MurrayPatrick-
The jig is for use with a bench stone. The graver contacts the stone, and the "T" slides on the bench. There's a good picture in Perkins' book on the lathe.

Patrick WallinAw. A super fancy screw driver sharpener. Basically a stand alone tool.
Thanks bob.
