I’ve got boxes full of tools & gadgets that I inherited from my grandfather, his brothers and his father (who all immigrated from Scotland in 1910). Back ground on what they did, My Great grandfather was a Carpenter (must be were I got it from) Grandfather was a Machinist from the 20s thru the 60s and his brothers were both plumbers around the same time. I know what most are and what they were used for but there are some that kinda baffle me, so I thought I would use the vast worldwide knowledge of my fellow LJ’s and start my own series of “What is it? and What is it used for? “
1st item up for discussion is as follows.
It’s 3.5” Dia at the bottom 4” tall with a 1/2” threaded rod.
the body is wood (didn’t clean it up to find out what type, but it is hard) no markings on it.
The ends of the threaded rod have what appears to be centering points like it was centered in some sort of chuck or lathe.
So, LJ’s what have I got?
