Hello all,

I recently bought a box of odds and ends from FB marketplace and amongst the bits I know were these that I don't. I'm hoping they will be blindingly obvious to some of you.

The ball ended things are odd sizes, largest is 26.04mm, one is 15.80mm, another 13.50, yet another 12.40mm.

The cutters look familiar but I can't place what they are, parts for a shaper perhaps?

The ball ended tools remind me of those used by pattern makers of old. Internal corners of wooden moulds to be used in metal casting for would have been filled with melted wax and then one of these hot balls run along to form a perfect radius in the corner. The long length of the handles meant you could easily get into corners and not burn yourself.

Ball ended tools may be go/no go gauges for specific jobs. A part would be placed in a fixture with a template around it and the ball run along the template to check the part. If the small ball did not fit then the part was oversize and if the large ball did then it was undersize. It is a foolproof method for quickly measuring parts.

The bladed pieces are scribes for height gauges as already mentioned. I have a couple height gauges but only one of the scribes. Should have gotten a few when the company tossed them. 🙄 The tip of the one pictured in the close up is carbide tipped.

Definitely radius balls and height gauge blades.Both still useable and the radius balls are also used to form quick and convenient corner fillets for fibreglass components with wax or plasticene.
 
Thanks for all the replies,
Pattern makers tools would explain the odd sized ball ends, fractionally over an imperial measurement so you'd end up spot on for the mould.
Hadn't thought about a scribe, makes sense as two are marked 1.000" and according to the micrometer they are. Will check the others.

I did discover my digital calipers are out by 0.1mm so I'm not as bad a machinist as I thought, or at least not too bad for someone who started out with green woodwork
