I have a 7x12 mini lathe. As far as I have been able to find out the standard fee rate of the carriage is 256 threads per inch. I am doing some upgrades to the lathe. I changed the drive pulley from the stock 1.89 to 1 to a 3 to 1 setup with and an xl belt. I think ,but am not sure, that the new rate will increase to about 417 tpi. Can anyone conferm my figures or give me their own conclusions. Thanks Dave

The feed is geared to the headstock, not the motor, so your drive doesn't affect the feed.
