I just finished converting my "OLD" Delta/Rockwell lathe into a variable speed, reversible unit and it actually works, finally. If there is any interest I will offer information on material and drawings/information on installation. Even pictures if requested. I'll watch this OP or respond to PM.
Thanks for reading.

Prove it let's see you turn a pen backwards:wink: Please remind me what you use reverse for on a lathe. I know it was discussed here a while back but I honestly cannot remember what you would use it for. OOPS my skill level is showing:redface:
 
Why reverse?

I use Reverse on my Delta midi lathe when I sand. Dust goes in the dust collector rather than in my face. I also use it with CA and other liquid finishes. I don't miss getting the "racing stripe" on my shirt, neck and face shield.
 
Taking reeves drive lath to EVS quite an accomplishment. Tips on buying components, wiring, lathe modifications, and mounting components tad more important that why make lathe go in reverse!

Some people go to the other side of the lathe to turn too! I have reverse capability and sand using reverse, no room on other side of lathe to turn.
 
Using my scrap pile and some searching on line, I have some $200 in the mods. I'll try to get picts and a write-up this weekend. The 1 hp motor was from Surplus Center at $49 +ship and the VFD from Galco KBE2-2202-4 under $130 + ship. Additional parts needed will be a 5 or 10k pot linear taper, selector switch with 2 maintained contact switches - center off (for forward/stop/reverse), E-stop switch that holds in stop position, box for controls, disconnect and assorted wiring. I'll post picts of all this. Hope this gives you a starting point.

OK Here it is. I think I have covered the mods, but I am well known for not being qualified to think. The best way that I could come up with getting this thing here is with a PDF. If you have any questions, I have this post on subscription and I answer PMs. Hope this helps.

With a very limited knowledge of electronics, I did follow what you are doing, Charlie. Only area of confusion, which was cleared up later, is "E-stop"---which I now know means EMERGENCY stop.
 
Charles--

What lathe are you running? I saw a reference to a Reeve's drive above. Is yours a stepped pulley or Reeves? I have a 1971 Delta-Rockwell 3-phase that I added a VFD to so that I have variable speed from 0-3k rpm, but would like to add in a reversing feature.

Here it is with the VFD on the wall:

Brad,
I have that VFD on one of my lathes. You can reverse from the control panel if you don't want to set up a remote station.

Press DSP/FUN (Display Function).
Arrow down to F03.
Press DATA/ENT (Data Entry).
Arrow up to 001 for Reverse.
Press Data/ENT.
Press DSP/FUN.
Press DSP/FUN again to go back to frequency display.

To change back set F03 to 000.
