Need jig for sharpening lathe tools

Mar 24, 2005 14 Replies

Does anyone know of a source for a jig to use when sharpening lathe cutting tools. It would need to handle the compound angles found on most cutting tools. Sometimes grinding machines come with a tilting table with a miter gauge attached. That is what I need, but I don't want to buy a grinding machine just to get the jig. Thanks in advance,

Have a look at the Glendo Grind-R-Table:

See previous discussion re. Glendo. You can buy only the tilting table and cross slide protractor guide to use with your own bench grinder.

Delta makes a "uni-vise" that can be used to hold things a surface grinder. Works well but grinding toolbits on a surface grinder is SLOW.

A low cost solution that has worked well for me is to buy the Veritas tool grinder setup. The tool rest is $39.95 and the grinding jig is 19.95 .. you can buy the entire setup for $52.00 .. I made an additional jig for holding lathe bits. One nice thing about this jig is that there is a couple of hundreth's play in the slide. You set the tool with the jig on the back of the slide and then with gentle forward pressure you grind deeper without burning the bit. A fancy compound table would be nice, but this is an adequate compromise quite suitable for home workshop use.

I second the motion on the Glendo table. It's intended for a 7" or 8" grinder, but I adapted mine to a 6" grinder by putting a riser block under the grinder. It works very well.

I sold my Baldor/Glendo/Darex unit locally, Robert. I don't think I priced it correctly because the demand was very strong. I'm afraid I disappointed a lot of guys.

I'm honestly suprised that Harold had not weighed in on this thread. Most lathe tools can be ground offhand pretty easily - are you making some specialized tooling that is particularly tricky?

Harold probably gave up trying to get his point across and I don't blame hime. After reading his posts I went out to my shop and removed the little table on my Baldor 612 leaving only the arm that the table was bolted to. That arm is a handy knuckle rest and now I totally agree with Harold. I've added another trick and that is to use a small vise grip pliers to hold the bit if it is not already mounted in a quick change holder. Harolds method gives _much_ better feel when grinding. I threw that useless little table in the trash can. Phil Kangas

I can't find information about Veritas. A Google search didn't turn up any company by that name connected with tooling. Could you please give me a url?

Thanks,

Veritas is marketed by Lee Valley Tools:

I recall back when I went to machinist school we were given wood tool blanks to practice with. I know it sounds corny but if hand grinding tools is a problem play around with some wood blanks make em 1/2" pine. The instructor also gave some good lectures on cutting geometry at that time. Great program it's all cnc now.\
