The table was antique before my parents got it sometime in the late 1960's, it is just like crashing and repairing a race car. A couple of decades later it is just another bit of it's history.

What nice stories you have, once I had a motorcycle engine on the table in the bedroom. I need some thinking of what I could do with it.

http://www.astrofriend.eu/vehicles/m.../minibike.html

But now the problem are of smaller physical size.

Today I have found shims washers of steel, m40 ID 50 OD, 0.1 and 0.2 mm thickness. I don't trust these plastic shims, the old are deformed by the pressure. It will come photos later. I will keep one plastic shim on top to have it act as a spring when length of shafts changes because of temperature.

I wrote to the university where I studied once, thay had a terrific workshop. But they didn't have it anymore, I must look for a lathe somewhere else.

Everything are in progress now and I can't see any problem that I can't fix.

Sounds familiar.

My dad used to repair the Kombi motor on the kitchen table. In those days there was no garage with a workbench I suppose.

Must run in the family as when I came home from school my brother had his triumph Bonneville in parts on newspaper in the lounge room.

I like the sound of onstep for the EQ6/EQ5 with belt drive. . I should try that next , having tried it on the fork. Just need to get the wireless module to work.

A table which we still have and that half a century later still has marks on it to prove it where oil went in to the oak and marked out the corner of where the head was sitting one time, among other things like a clear imprint of a ball bearing.

It's always so much to do, but this weekend I got some time to work on my EQ6 mount.

I have removed the paint on the surfaces of the lids that cover the worm gear.

You can follow the work here:

To my surpise one of the surfaces was not milled, anyone else that have found that too ?

Whenever I have situation like this, I use a large enough sheet of sandpaper on flat surface.
This way the final result is close to what it would be if the paint was removed on milling machine.

Have to agree, I have a marble cutting board that is never used as a cutting board and place a large sheet of emery paper of varying grits to get an excellent finish. Not much use for protrusions but can be manipulated to get in some tight places.

Yes I thought about that, but then I need to find a flat surface with a hole to let the RA shaft through. But even better with a lathe, then I get the surface orthogonal to the RA shaft also.
