Default More questions about rockwell 100

Hello all. I was given a benchtop router table with an old Rockwell 100 mounted under it. My aim is to set up a dedicated box joint table that I can set up with an Oak Park style spacer jig, and not have to disturb it once it's adjusted right.

The router runs, but the bearings are squeaking and clucking like a chicken, especially when you turn it off. I found new bearings for it locally, but I decided I'd better see if I can get the router apart before buying.

A couple of years ago, there was a thread on this subject in the forum. It is here: http://www.routerforums.com/portable...se-sale-2.html

I followed Mike's advice about getting the round top off, but in my case, I'm going to have to be able to get to the bottom bearing. I can't see any way to do that without removing the shaft nut.

Here is an exploded parts diagram: ROUTER | ToolPartsDirect.com
As far as I can tell the Rockler 100 and the PC 100 are the same thing. In fact, the Rockler also says Porter Cable on it.

Since there is no spindle lock, I'm going to have to find a way to hold the shaft while trying to loosen the nut. As you can see in the photo named Rockwell 4 below, there is hardly anything to hold onto. Also, I hesitate to grip that armature with anything buy my hand.

One interesting thing is that the collet arrangement is different that the modern ones. The collet screws into internal threads in the hold in the end of the shaft. Could it be that the way to loosen the nut is to thread a bolt into the threads where the collet goes in, and then hold the shaft still with a wrench on that bolt while loosening the nut with another wrench?

I took a few pictures, not good quality, that might help show what's going on. Any suggestions greatly appreciated. Thanks. Jim

CAT makes a fabric strap wrench for filters that should hold the armature without doing any damage. You could also place rubber under the strap as a precaution.
