It’s not real big, but I tried to make it beefy enough to do actual work, rather than simply a display piece.
I imagined it as 1/6th scale, and what that might be like if you tried to make a rugged lathe, using mostly wood.
It’s 8” between centers, and a hair over 2” from the centerline to the bed. So it’ll turn a four inch piece on a faceplate, or 3 1/2 or so between centers.
I’ve got a jack shaft and pulley set to make before incorporating the lathe into the line shaft set up.
In order to use the lathe itself to make those pulleys, and whatever else I might want, without the location limitations of the hit and miss engine, Im rigging up a sewing machine motor that will drop fit into the m91 engine docking sled, as an alternative power source. The idea is everything more or less modular, plug and play. Once I get the jack shaft set up, I plan to run the lathe through the line shaft, using the M91. It won’t spin nearly as fast on the hit and miss as it will on electric , but with the proper pulley set, ought to have plenty of power to work at reasonable speed and cutting rates. I’m thinking along the lines of a foot powered lathe as were common in the 1700s onward. No ball of fire, but with patience, they made all kinds of nice stuff.
