Interesting.
Could you post some pictures of what the nose sprocket looks like on the edge/ What the sprocket looks like?

Sure
I might have a few.....hundred
Roller nose, they were fairly common on vintage saws and sort of fell out of favor when the sprocket tips became more available. They basically did the same thing, relieve some of the friction/heat a chain made going around a solid nose bar.

Thanks Jason. But the chair was in focus, not the bar. If you'd take another? thanks!
Merry Christmas!

Smooth groove can be used with any pitch chain.

Really?
I see it's just a pulley not a sprocket. That's why I wanted a better picture as was curious if it had driven teeth.
Merry Christmas!!!

Good to know. Merry Christmas
The problem with the roller nose bars is that sawdust or twigs can get caught in the gap between the bar and the roller and jam the chain.
there was another style of roller nose that had less of a gap and would have been less prone to jam but still has the potential.
Roller nose bar work well for reducing friction and do allow you to run any pitch chain, but they are not a great choice for bore cutting or for use when the bar will be buried.
