These items are quite simple so I have lumped them into one thread.

The tail stock stop collars are attached.

The dimple caused by the set screw pressing against the eccentric was JB Weld filled and filed down.

A 3/8" wide strip of sheet metal was formed to a ring to slip over the area of the eccentric that the set screw presses against. This could be up to 18 Ga thick(this one is thinner). I believe this will serve as a sacrificial lamb rather than future dimpling of the eccentric. There really is room in the casting for the 'ring'.

All put together and ready to 'turn'.

The post is inserted into the tool rest arm and secured with the set screw. No Rob someone else added the 'knurl' marks:eek: before I acquired it.

The tool rest is secured to the arm by a set screw.

And there it is! Told ya these things were simple.

Now for the lesson learned on these items. Y'all have likely noticed a bit of two tone coloring of parts so far. I first primed with self etching primer, then the gold parts and after masking that off, painted the copper part.

As I peeled off the masking tape, the gold and primer pulled off the part.

I concluded that I had skipped a step prior to priming.

I use the electrolysis solution to clean parts after paint removal(it is handy and acts as soapy water). I neglected to rinse it off! So the primer had poor adhesion which led to the peeling.

Lesson Learned!!!!!
