    13" Lathe Large V-Belt Pulley Size

    I recently picked up a 13" SB Turret lathe that has the 3-step cone pulley set-up. The previous owner changed the v-belts & pulleys to apparently make run it faster than normal? I want to try to get it back to as close to the original speeds as possible. According to several manuals I've...

    I picked up a Ex-Cell-O carbide tool grinder awhile back from a on-line auction & I finally got around to cleaning it up & going through it.

    Help identifying old pedestal machine base

    Maximum Motor size with 3HP RPC

    I have a 3HP RPC & was wondering if it would be capable of starting a 5HP radial arm saw motor just to check the motor out? The RPC uses a potential relay for starting the idler & a size 1 AB 709 starter with three #49 heaters (7.33A) for idler control & overload protection. The FLA of the...
