What are these please?

[Deadeye]

Sorting out my late father-in-law's stuff. Three mysteries:
1. Is heavy and about 15cm long.

2. Is also 15cm long (ish) and has a numbered dial at the elbow

3. Is about 200 hard plastic balls, in 2 sizes - about 3cm diameter, solid apart from an 8mm hole to the centre, and about 12mm diameter, with a 5mm hole. I also have red ones the same. They don't seem to be to make garden canes safe, or to build 3-dimensional models of molecules.
Any ideas?

Sorry about the image repetition - all 5 are there but in the wrong place and the wrong order!

Mod Edit:- Images sorted.

First two items are a Tormek style (Sorby?) support and Jig for sharpening Wood turning Gouges on a bench grinder.

Thanks CHJ - makes sense!

Balls look a bit like handles? I bought some similar ones for my drill a while back.

Could be knobs... but no threads and who has dayglo?

Does this help?

PM me if you would like a copy of the instruction sheet.

The balls are often used on the end of rods used for indexing or knocking out Morse tapers on a lathe.

Also in the 70`s they were hung on strings and called "Klackers" - great for breaking your knuckles......

If you are going to sell the balls I'm happy to take 20 of each size off you?
