I’ve been planning on making a treadle lathe for awhile now. The design I settled on will have the drive wheel off to the side to accommodate for its large diameter. A problem I encountered is that I don’t have a band saw to cut the curved felloes and I want to make this lathe as much as possible with tools available from the late 18th century. No problem right? Just make a Felloe saw.
I’m in the mindset that bigger is better (not always a good mindset) so I researched old photos and came up with a saw that is 40 inches square. I used oak for the top and bottom stretchers and to cut down on weight I used pine on the sides. Al l the corners are chamfered for comfort as well as looks. I forged the hardware because I didn't want to have to use any tools on it when I tension the blade; also I wanted it to look 18th century. The blade is made from a 3/8th inch band saw blade.
I think the saw looks great, but then my standards are low. The real issue is the saw is not controllable, the blade folds over and the saw will not cut to a line. I’ve tried hook tooth blades and regular tooth blades without success. All my blade widths have been 3/8 inch. Maybe I need to try a ½ inch blade. Do they make band saw blades of different thickness? Maybe its not ridged enough. Please if you have any suggestion let me know.
