Shop Assembled Cutter Grinder
I had this XY table for the past 30 years and only used it on the drill press.
But then I purchased a small mill and no longer needed the table.
Well now that I have a mill I needed to sharpen some cutters.
Works well for Lathe tool bits as well.
The column is just a hunk of heavy steel tubing. Riding on that is the mount for the grinder.
That would be all aluminum except for the 1/2-10 Acme Lead Screw. Used for positioning the
height of the grinder which is then locked by the two rather large knurled aluminum lock bolts.
The XY table has variable positioning so it may be located for various setups. The column may be relocated
to several fixed positions. Right now the grinder seems a little under powered. I am going to replace the grinder with a larger model and see if I can get enough power for some surface grinding. That should make this a very useful tool in the shop.
So far it has been used for lathe tool bits and end mill sharpening.
Several accessories are shown which include a multi angle fixture that can hold just about any tool at almost
any angle. It's main use if for lathe tool bits.
The spin indexer along with the shop made index pointer is used for end mills. With the index pointer it can sharpen the flutes as well as the ends.
I will post the new motor and report on how well it can be used for a simple surface grinder.

I added a fine feed to improve its use as a surface grinder:

Upgrades Magnetic Chuck and Power Feed Heat Sink
First I received my magnetic chuck and was ready to check it out with my power feed. The motor is just a car seat actuator and not intended for continuous use. Hot it was. Hotter than the one on my mill and I suppose that is due to the constant use while surface grinding. So, we made a bit of a heat sink from the scrap pile. Should do the job. The portable control box is shown in one of the pictures. The more I use it the more I wonder how I would do without it.
