Home Made Tool And Cutter Grinder

[coffmajt]

Just finished this stage of the project and some test sharpening on some dull end mills with good results. The plans came from an Australian web site and I have about 150 shop hours and $400 in materials invested but I have also learned a lot in the process. Next phase is building attachments to sharpen drill bits, lathe tool bits, and saw blades of various size. Attached are a few pictures of the tool holder with end mill in place.

That is a thing of beauty! ....and could I ever use one too.

Another project for the list.

Thanks for sharing!

Hey coffmajt,
Does your tool-holding spindle use a collet system? If so what size?
Could you share a link to the site with plans?
Thanks,

Plans came from ACTO http://www.machineryplans.com/product/acto-tool-and-cutter-grinder/
The spindle is bored to accept R8 collets. The plans are metric, which I converted mostly to English due to materials being easier to acquire here in the US. Thanks for the posts -- Jack

Well done. Wish I had the time to build one. Too many broke guns.

Funny I just picked up the grinder in the picture, now my minds going in several directions , this will be a quandary . I like the fact it uses r8 collets , I've wanted an endmill sharpener. Think I talked myself into it thanks the plans will help.

I know that this is a rather old post, but what is the verdict on this setup. I would like to have a tool grinder and I think building this would be great at increasing my understanding how this works. Are the plans worth the $50?

Edit....Looks like there are downloadable plans readily available for the "Bonelle" tool grinder. Just downloaded some that were produced by "J. Willis". Ahh, another item on my project list.
