Sewing Machine Bits

[Maurice Cox 1Participant @mauricecox1]

I was recently given a defunct sewing machine to dispose of in case I wanted the motor. This motor was in good nick and really quiet, so that came off. I then had a look inside to see what was there. Lots of weirdly shaped rods and levers that could only one use; their original one! However, I found that it also contained a pair of helical gears with a 2:1 ratio; one steel, with a bore of 1/2", the other is brass with a steel cam press into it. The cam has a 1/4" bore and could probably be removed leaving a 7/16" bore. The shaft centres are 3/4" apart. It made me wonder if there are any I/C engine drawings that these gears would suit? Or are they a bit on the small side?

Sorry about that, I forgot to title the post as" sewing machine parts". I'm getting old! Perhaps the moderator could correct my stupid error? Sorry again.

Un-confusing Morris…

Hi Maurice,

I assume these are crossed helicals giving a right angle drive. With a bit of adjustment to the design I think that ETW's Wyvern or Centaur could make use of them.

Cheers,

Rod

Thanks Rod, I think that I lay hands of a “Centaur” without too much trouble. I shall investigate and see if they fit. Also, thanks to the moderator for fixing my stupid error!

Look carefully at the machine as a whole, I'v got the bits of two of them here, and I'm harvesting bits of cast iron for various little jobs.

If anyone wants a 240 volt motor from a sewing machine, with variable speed control, just PM me. I am in Cambridgeshire.
