Gear wheel 45mm in diameter with 70 teeth

I held off offering to make a gear for you as I read it that the "I fixed it" factor was part of the entertainment value here. But I'm W Gloucestershire if that helps, and although I haven't checked there is a 43 tooth circle on my dividing head I'm pretty sure there is. If it helps to rattle one out I'm game.

Looks a bit like this set up from Doll & Co. or Carl Doll (**LINK** You can probably count the teeth from the photos.

Not sure we've got the full story yet. Looking at the photo, I see the big gear wheel rotates freely on an axle, and the the axle is quite long, ie able to accommodate something wider. Could it be that the original was a compound gear, with the drive taken off the smaller wheel?

Anyone know what the original engine looked like? The engine appears to have various practical ways of taking off power and a single gear in that position would be an idler. Unless it was only ornamental?

Oh dear, I shall be counting rivets next.

Edit:  Dick H got in as I was typing with a photo.  All is revealed.  I guessed a compound gear, actually it's a gear plus  pulley!

Exactly so - this forum is hot stuff! It being only a pulley is good news - much easier for Bill to make than another fiddly gear.
