Nice tool Ralph.

The Hemmingway design is based on the excellent Marlco knurling tool. The one thing that it misses from the original design is the cam for fine adjustment of the top knurl. It is a very simple modification the fixed pivot on the upper arm is replaced with the cam and the pivot extended to allow a handle to be attached. Such a simple addition but the effect :drool:

Xldevil:
Hello,Jo.
Thank You for Your nice words and Your hint.
Hemingway is offering a fine feed,actually they call it sensitive,knurling tool as well.


So far,I didn't missed a fine feed for the tasks I did.
If I will,I probably modify it in the way You suggested.
Cheers,Ralph

Arbalist:
That second Hemmingway Knurling tool looks interesting Ralph doesn't it. From the Hemmingway site:

"This item became a standard in the toolroom; allowing operators to feel the knurl being generated and adjust the pressure to both arms using fine feed lever"

Mine works fine but that's no excuse not to build another one in the near future!  :beer:

Vic.

PS, I noted that Hemmingway supply English made Knurls. Anyone bought these, are they noticeably better than those commonly available?

Xldevil:
Along with the knurling tool kit,I bought two sets of knurls from Hemingway.
Don't know if they are better than others,but I'm pretty satisfied with my knurling.
Anyway,who likes to buy far east,if one can get European made?
