I want to rescue these old primitive pieces of bench mounted machinery, even though I really have no use for them. It's in good shape, the table doesn't even have drill marks. Looks like this one might have been converted to a V-belt. With the two sizes of gears on the drive wheel, could it have a high and low speed, controlled by the handscrew wheel on top? Not sure how that works.
The handscrew at the top should be the feed screw...it's all the way down in these pictures. This machine does not have auto-feed like many of them do. High and low speed is shifted by pulling the horizontal pin visible in the middle picture and decoupling either drive gear. That shifting mechanism though is intended for hand crank operation; using a belt you would change the pully sizes. lol I don't think that modification is manufacturer-authorized (or particularly safe...beware of shrapnel!).
ReplyDeleteThank you, I expect the speed changes were infrequent but feed rate must have been slow with the screw feed. With a stepped pulley you're right, much quicker and safer.
