that head case looks just like mine but a much nicer finish, my lathe has 420-y on the gear cover plate. has the flat apron thats broke and i would love to know if a model c would work on it if i bought the entire saddle, my compound is flat wore out, yeah my lathe was a freebee and is in dire need of repair, short serial number and no letters, i did get a bunch of tooling and the entire change gear set, the bed is good, tail stock is sloppy, part of head stock is broke where the back gear is but runs nice, have collets also, i have since upped it to a 1 1/2 hp motor 1750 rpm, yeah i like power over kill but i can now make scrap a lot faster lol, yesterday i was getting up to 6 feet long ropes of mild still for chips at a cut of close to 1/16 or more with out back gearing and useing carbide, alum i went as deep as 3/16 and it was just ripping right through it, i now have a 5 gall bucket of alum i filled and stepped on to get more in and probly filled it in 2 hours. i made a 3 step pulley for the motor. bout 1 1/2 3 1/2 and 5 inch, yeah i keep it flooded with oil and im thinking i might need to build a drip pan and just plumb it up with a filter and pump, would be cleaner and cheaper then buying this stuff in the gall... its a oily mess and well its will coat you in it as well,,,, i wonder if cone bearings or another type of bearings would be better for more speed then the babbiting or so that its got now..... the size suites my needs but the factory power and how long it takes is a waist for me, thats why the upgrade, any ideas and all help is welcomed and needed, can email me
