Stew, considered this also but got told that since all wheels need depthing out to scribe onto the frame, the small adjustments needed by lanterns would hardly be noticed. Only what I got told.

I've got ideas to make a multi tooth pinion cutter.

As for the clock all I've decided is that it will be a skeleton clock.

I'm still very much getting the kit around me before i make a start, I also want to get a couple of other projects done and I want to complete the lubricator and boiler feed pump for my loco first, so I guess I wont be making a start until the new year.

Chris,

Even though it is offset, imagine if you could zoom right in on the cutting edge, the clearance angle on the bottom edge is tiny, it's still almost tangential since it is a radius so some rubbing will occur, why not grind a straight line clearance between each end of that arc, then you know you've got a decent clearance angle.
