Re: Edelstall cutting tool system
|
My father bought the boring bar portion of the system, and I still have it and about 3" worth of the consumable tool stock.? I haven't used it very much, but it's worked very well when I have.? I don't recall which tool stock I have, but it's not carbide (which I think is silly for a unimat anyway).? It works best in brass or aluminum, and with as little "stick-out" as possible.? (I did use it with leaded steel once in the 80s, and it worked great too) Since the bar is round, you have to ensure that angle of attack is correct for your use.? As I recall, the benefit of the formed tool stock is that you just have to grind one face, and the other angles appear as if by magic.??
As to why it didn't catch on; it's non-standard,? If they had made a version for larger lathes it might have (assuming it worked well on the larger lathes).? After all, a lot of people find grinding bits troublesome.??

Shortly after acquiring my lathe I ?was called away from home for an extended length of time, finally after getting caught up on my chores I¡¯m able to spend some time with my new to me lathe.
Being an absolute beginner I did read the manual and watch some of the online videos that were suggested.
I ground my first cutting tool and was very happy with the results. It was probably the easiest shape to do. 10 degree on three sides, it was for brass stock.?
I was wondering if it was worth time learning to use and sharpen these bits? Looks to be a complete 13 piece lathe tool set. I wasn¡¯t able to find any replacement inserts online.
Did these not catch on?
