Aye - fair play, Mike. Mine has been sat on my spare room window sill...

Will try to get it fitted over the weekend

Could do with an update on these motors chaps.

Wow - it was two months since you kindly sent me one of these motors, FOC Sorry for the delay - I finally got a chance to try it out today.

I dry fitted the motor into the gearbox and ran it off of a 12V feed and I can confirm that the gear meshed perfectly See first pic to compare the gears on each motor.

You would need to do a little surgery to fit the bigger motor - you can just see one of the existing screw holes on the second pic and can compare the mounting holes of both motors on the first pic. The original is on the right and the one that Mike sent me is on the left.

I re-fitted my original motor for now as I suspect that the new motor speed won't be a like-for-like so may need some attention on the variable resistor on the wire feed board. But a very handy spare!

And I re-greased the gears...

So I can confirm that Mike's motors seem like a perfect replacement for the existing ones (SIP Topmig 150).

Thanks Mike

Thanks for the update (and PM) Skotl. I was surprised that the orignal gear worked as other chap had to (chose to) swap over with original gear. The motor runs at 3000 rpm and is then dropped through a gearbox ( same as in welder) I should have about 30+ of theses very soon! Gearboxes are more substantial than the plastic? one fitted to your welder and all metal gears but the out put shaft is only aprox 6mm dia where most wire feed roller shafts are 8mm plus. No access to a lathe to upgrade them, doh....

Cheers Mike. I ran your motor with its gear "loose" (just poked thru the gearbox hole) and it ran just fine for the 30 odd seconds. I suppose it's possible that it wasn't a perfect match but it seemed OK to me.

So you'll have 30 motors or 30 motors and gearboxes? Yes - the wheels in my box are plastic. They seemed in pretty good shape but I greased 'em up good before closing up the box.
