    Welcome to the forum! Is your reeves drive damaged beyond repair?

      No, it is not damaged at all! I just wanted to have a digital system and reversible motor

        In that case leave the reeves drive, just change the motor for a 3 phase. You will not need more than one hp as you will have the low speed of the reeves instead of running the motor at 10hz.

          if you just want to have reverse, add a reversing switch!

            Right now, the lathe is 220V! How would I have a 3 phase system! How would I do that! I’m no electrician!! Would I need a VFD? If I leave the reeves drive, How would I change from one to the other? It would seem to me, that I should take out the reeves drive! Add a 220V VFD and a 1 1/2 or 2 hp reversible motor and add a reverse switch! The problem is the pulley system!!! In other words, replacing the reeves system with a motor pulley and spindle pulley!! I just don’t know how that would come together!!! The rebel turner on YouTube did that conversion on his old delta lathe, but his lathe didn’t have a reeves drive!!

              Nothing to it. Get the frame size off he current motor's plate. Then buy a 3 phase motor with same frame so the pulley will transfer without any modification. Buy a suitable vfd, it will have all the controls built in to use your lathe right away. If you like you can add remote control stations for the vfd.

                Yes, but how does the pulley system work? The reeves system works by each of the pulleys squeezes in and out to change the speed! Also what should the sizes of the pulleys be?

                  You simply change the motor, keep all the rest as is! Make sure to service the reeves centre pulley, General used a high quality system but it needs lubrication as per manual.

                    Yes what he said ^^^

                    Leave the reeves drive there, just change the motor.

                      Is this what you have ??

                      The pulley on the headstock spindle opens up wider or closes narrower when you change the speed with the handle on the front of the cabinet, here is the spindle and pulley.

                      This is the handle that opens and closes the reeves drive pulley, (you van only do this with the lathe spinning) by doing this the headstock spindle pulley is made to change, this way the belt does not change size, the reeves drive pulley is shown bellow, the reeves drive pulley is driven with the V-belt from the motor, so there are two (2) belts in use.

                      This here below is what you would change to a 3 PH motor with a VFD, that way you do have double speed control plus reverse if you want, HTH

                        Yes, I’m trying to replace the reeves system and put a 2hp motor and 2hp vfd! I don’t know what size pulleys to replace the expandable pulleys!!

                          It doesn’t matter what size you use.
                          You get variable speed via the vfd.

                          You don’t have to replace the reeves pulleys, you can leave them and just switch out the motor.

                            You will have a tough time getting a small enough 2 hp motor to fit. I do a lot of conversions and 1 hp is usually as large as can fit. Then just leave pulleys.

                              So why do you want to remove the reeves drive ??, as you said it was fine, or what do want your lathe to do that you can not do now ??

                              See with the reeves drive you do have full power over the whole speed range, because as you change speed with the reeves drive from slow to fast, the motor does run at full speed.

                              When you use a VFD that is not the case, and so the lathes with VFD like Stubby and Oneway etc, use 3 speed pulleys to be able to go slow and fast and having enough power.

                              The 3 PH motors will loose a lot of their power (as do others) when you dial down their RPMs, so there fore they all use step pulleys to accommodate this problem.

                              You will not be able to go with just one speed v-belt pulley and then use a VFD to be able to go all the way from slow to fast, as you will not have the power where you need it, (at slow speeds you do need the power to turn and cut larger turnings)

                              However if you keep the reeves drive you already have and just change the motor to a 3 PH, you then add the VFD and will have the added speed regulation from the VFD plus the power where/when you need it, as you will be able to have the motor spin faster while still having the spindle turn slow.

                              All up to you now, but I would discourage you from removing the reeves drive and replace that with just one set of pulleys, you will not be happy guaranteed
