Thats funny.....mine is a brother to that one,and it has metric at the flick of a lever.No extra gears needed..............and as to lathe parts ....if it aint Chinese,parts cost more than any old lathe is worth,no matter what the brand......The secret is to carefully inspect the machine before flashing yer wad,and use the spares as a beatdown point........As to bearings,with a slight modification ,there are several options to use standard taper roller bearings.......all of which I have done over the years......PS the Master I have now cost me zero to acquire,and then the cost of a couple of standard taper rollers......And the machine has a strange history,it was nicked bit by bit from the gubmint......dunno how he got the bed home........he also nicked a Weiler lathe in bits ,which ended up out in the weather when he died.......I might add,he also had five Manx Nortons,and tons of parts......which I didnt get.
