Frankengrinder project

[Dan S]

It’s not even Halloween yet, and I’m already getting cabin fever, so its time for a project. My cheapo bench grinder ($25) worked well enough for me to get by, but its time for an upgrade.

Here it is in all its stock glory. Shockingly the shaft only has a run out of .0002” .






Hopefully, I will have my new wheels waiting on the front porch when I get home tonight.

MSC was on time as usual. The Norton wheels look a lot better new than the imports did, the mounting holea are actually round and has crisp edges.





Earlier this week I turned a prototype spacer/flange out of aluminum. The space slides onto the shaft, and then an internal shoulder butts up against the shaft shoulder. I have to wait until Monday to make the actual pieces (need to pick up some 2.5” aluminum bar).

Took me a little longer than expected, but both the adapters are done. I haven’t hit the wheels with a diamond tool yet, but they seem well balanced from the factory. The next step is to make a new tool rest, I really like the one pictured on this Japanese website.

I managed to finish up the supporting structure of my rests yesterday. The arms are made of ¼” thick aluminum bar that I cut to size on the table saw using a Freud Diablo blade, and a jig I made out of MDF. The cross bars are round stock that I turned down to 3/8”. Everything is held together with 10-32 socket head cap screws.
