A Pair of Gears please.
Hi All,
I'm after a matching pair of gears or cogs to make a swager.
They need to be between 1 1/2" (40mm) and 2" (52mm) in diameter.
The number of teeth doesn't matter as they will only be driven by hand,
but they would be better if they were straight cut.
The important thing is that they are the same size.
The pic shows the sort of thing I'm after.
Top one is a feed gear off a Harrison lathe.
Bottom shows the gears on the end of my 3' rolls. (I'd prefer to keep them on the rolls)
Beer tokens or payment in kind await.
Anyone got any laying about?
Or know where I could buy a pair new?
Many thanks
Paul G

Paul , similar gears come up on ebay pretty often for Myford lathes for not a lot of money.

What about the gears from 2 old starter motors. You'd need to make up a shaft to hold them but it wouldn't be that hard surely.

Hi Rusty,
trouble is they tend to be odd ones or sets, i.e. 20t 25t 30t etc.
I need two the same, but I will keep an eye on ebay.
Thanks mate

Don't think they would be big enough m8
Here's a pic of a swager to give an idea of what I would like to make.
(missed this last night on ebay, by £1 )

What's the diameter of the 21t's
i.e. centres when meshed together?

Too small and too big I'm afraid Rusty.
I'll have a look on that web site.
I wanted to make the shafts from 1 1/2" and the tools from 2" HT bar. ('cause I know where I can get some)
Then I can make them longer. (ribs in sheet?)
Thanks a lot anyway.

HPC in Lancashire somewhere have a book full of gears of all possible sorts.
I used them to repair a lathe some years back and they were spot on.
Hinchcliffe Precision Components is the full name

Could you
Use a pair of bike sprockets connected with a short chain ?
yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

Hi Tim
You have u2u
(Looks a bit too posh for my garage mate)
Gary, Thanks all the same.
Pete, With a chain both shafts would rotate the same way.
I need one to go c/wise, one anti c/wise so they feed the sheet through, hence, two cogs.
All the web sites I've looked at only give the number of teeth, none give the diameter.
Anyone got a Myford lathe and can tell me the number of teeth a 45 or 50mm change wheel has?
Many thanks
Paul G
