2020. 1. 16. This is a drawing for the tool post grinder spindle. It will use two single row angular contact bearings with a 20 mm bore, 47 mm OD and 14 mm wide. There are four bellville washers in series to provide the ten pounds of preload on the bearings.

2020. 1. 16. I know the manual that goes with an Atlas tool post grinder (don't have the grinder, but read about it in the manual I found somewhere) stated that the work surface should turn against the wheel. They recommend turning the lathe spindle in reverse for OD grinding, even though the Atlas uses the same threaded spindle arrangement as your South Bend.

2020. 1. 16. They are a little light, but I engraved degree markings on the bottom plate. I doubt they are really needed, but I put them there for reference. Once the grinder is mounted and set at spindle center height and locked there,it won't get moved. the grinder will be square with the "0" mark. There are 90 degrees on either side of zero.

I'm considering building a tool post grinder.

2009. 12. 16. What to do...collect a bunch of parts that resemble the parts of the tool needed, configure a design that would allow what was available to be used or modified and used to create the needed tool, or to make the tools capable of creating the parts for the tool needed to solve the problem.

2016. 7. 3. The arbor fits my grinder spindle perfectly. I can extend or shorten it as needed. I also need an arbor to hold my 3" diameter external grinding wheels. I used a piece of .750 drill rod for sturdiness . Turned one end to .5000 " to fit the grinder spindle. I left a 1.50" center section.

For my miniature M1911 build I need some custom ground reamers, that where beyond the capabilities of my single lip cutter grinder regarding circular grinding, so I decided that I need an toolpost grinder. Not to hard of a task as I already had a Dunker DC motor rated 3000rpm at 12V and an spare spindle of my Deckel G1L engraver in my parts bin:

It takes 3mm, 6mm, 1/8" and 1/4" collets. The extended part of 3/4" diameter makes it easy to mount in a boring bar type holder in the toolpost. There is no noticable radial play in the collet, but about 0.010" end float. You have to be able to preload the jaws to take the backlash out of the scroll.
