lathe change gears??

[Rig Pig]

Just sorting out some of my junk and moving some bits into the workshop when I came across some change gears that came with a job lot I bought years ago, they are painted gray and range from 36 to 95 teeth, there are 33 of them. The only other info stamped on them is DBS they have a 32mm hole with a keyway and are 19mm thick.

Anyone got any idea what they are off?

Anyone got any idea what they are off?

On this forum I almost guarantee it... I am looking forward to the day everyone is stumped

You could give the diameter and N of one of them so we can see what size they are.

Add two to the number of teeth and divide by diameter, it will give you diametrical pitch[dp]

my lathe gears are 16 dp, I think that's a fairly common size but mine are narrower than 3/4.

Good point I will have a measure up.

Wow 32 diam is canny, Sorry DBS doesnt ring any bells,The popular Harrison range of Lathes, are 14DP for the change wheels, I can check bore and keyway but definatly NOT 32mm.

Definitely not Drummond. Any photo's? You planning on selling them?

I will pop some photos up in the morning, I suppose I might sell them, I was planning on using them for a G. Thomas style dividing head but they are a bit heavy duty!
