Tool Post Grinder

[Andre]

I found those Dremel chucks have to be run on extremely accurate threads, or else they don't run true. One or two thousandths of slack on the OD and they don't hold perfectly true.

Anyways, very nice work. If you find any vibrations induced by the cog belt, try a round polyethylene belt. You'll probably be fine though.

Looks good should do all you need. I could never see paying what they want for a tool post grinder. Old junk even brings a $100.00 OR more on used ones. The high priced one won't do any better then yours ill bet you have less then a $100.00 invested . Ill eventually build one too. Thanks for showing yours .
Every different idea helps.

WoW! That thing is AWESOME! You're giving me the vapors to try it.

I really like the concept. I've been wanting to make my own tool post grinder using a router also. I have an old Craftsman router that is just single speed and a new Makita that is variable speed. Which one do you recommend I use? I also have chosen to use the grinding wheels from a Souix Valve grinder as my source of grinding wheels. They have steel threaded inserts in them and screw onto a male threaded shaft. I bought the tap and die for the thread so I can make my own spindle shafts. Saved all the PDF files to my computer for future reference. Would love to see a short video of it in action. Is there a list of materials you used available?

I didn't like the price for one so decided that it would make a good project.

Me too. Now that I have plans , I think I'll give it a try.
Please follow up with changes you make and things you will improve.

Thank you!!

The router worked OK but the speed control was kludgy. I have since replaced the router with a 500 watt DC motor with power supply and speed control. Picked it up from Banggood in China. I can take some photos of the motor and the power system if that would help.

yes that would be great. I am mainly interested in re-grinding my chuck jaws.

I hope you can see from the photos that the basic tool remained the same. I just had to make some changes to the motor brackets and the pulleys. The power supply and the controller are housed in an electrical box that has a main power, a on switch, and a speed reostat on the cover. The box hangs on the chip tray of the lathe when I need to use it and is stored away at other times. Any questions, don't hesitate to drop me a note.
