New life to a old hockey puck

PekkaNF:
I'm working on this one.

Let's see how it comes out.

Well, so far so good Pekka, but just what is it you are working on? Or must we wait and see? Looks like it may be a castor ("caster", depending on which side of the globe you dwell) or something to me.

Nothing special. Just a puck lying on floor, a big washer as bearing plate (there is going be slight camfer on ID hole) and a carriage bolt to provide concave surface to allow a little tilt.

The screw is differential screw, but I don't know if it works good enough. M12x1,75 vs. M16x2,0 was the combination that came with tyhe tools I have and standard bolts. I would have prefered much M12*1,5 but that is not a standard. M10 but it looks thin and Could not have used standard long nut.

This screw gives a very sensitive adjustment range, downside is that there is very little of height adjustment overall. I need to get the machine fairly close to level to start with. This Grinding machine has three mounts. I'm planning to put single non differential screw on rear, get it fairly close, and use these more sensitive ones on front feets.

Started cleaning the lathe and chuck to change ouside jaws for hockey pucks and the chuck seized...not solid but I was not confortable to use use any force. Vacuum cleaner and a fiddle did not help, I took it out, dismantled and cleaned inside. There was very little debris inside...bit it was a piece of swarf between chuck body ways and jaw tooth. It's all it takes.

OK, two more pics, they should be pretty selfexplanaory..I spent more time on migrating from W7 to Windows #10.

Ruber was pretty hard and nice to turn,  but messy. Not quite like cast iron, but clearly messier than I'm used to. Whole lot nicer to tun that softer rubber.

I didn't find a proper M16 long stop screw I need to buy one and a lock nut on it. Those ase missing on the picture. Slight change of plan.

I put rubber in the freezer when I have to machine it. Particularly good when doing things like trying to drill a hole in a rubber stopper. But hockey pucks are nice hard rubber to begin with.
