I bought these a few days ago at a local thrift shop. They are small versions of dividers that I use fairly regularly. A 6 in. (150 mm) scale has been included in the photo for reference. The large compass on the top right appears to be hand made - it is quite well made with no name on it. It is a standard size. The inside and outside dividers are Moore and Wright and the small straight divider is a Starrett. The question I have is what were the small ones used for - model making or something similar? Thanks, John. |

I have the identical twins of the Moore & Wright inside and outside calipers - been in my tool drawer near the lathe for at least 20 years :bugeye: |

I don't have a clue as to their designated purpose in life, but I too, have the same small outside calipers. I set them to the target diameter when turning small bar stock on my lathe. For example, when threading and I need to make an undercut for threading tool to run out into. Mine were in the tool box I inherited from my late father, who was an industrial electrician/repairman.

That smallest pair of dividers is often stiffer than a larger set and so is better for marking out small features such as spaces or circles. |

Gentlemen, thanks for the replies. They are quite nicely made and a real addition to my tools whether I use them or not. For now they are beside my small taig lathe as it's likely they will be useful there. Andrew - You've had them 20 years but have you ever used them??? :wave: Chuck - that sounds like a good use. Pete - makes sense to me. Will try them out when needed. The compass is very nicely made but the pencil holder was too large. I made a brass spacer yesterday and epoxied it into place so that the pencil now fits very nicely. John. |
