Now for some wiring and testing.

It's too neat. It will never work! Does look like it should work though.

Just don't end up like this guy. http://www.liveleak....=48a_1454716898

Slow news day in Garden Tractor Land...
Instead of working on the Panzer, I spent the past 2 days working on my 1958 South Bend lathe. It's not a tractor, but it is a piece of good ol' American machinery...built in an era of quality and longevity and pride...quality castings...precise machined surfaces...designed for decades of dependable service...no planned obsolescence...no cut-rate materials...just good stuff. I dig it!
With my circuit laid out and most of the materials on hand, I've been slowly working the assembly process. First off, I gutted out the old wiring and the greasy BX metal conduit; replacing it with modern Carlon liquid tite nonmetallic conduit.
Having settled on the basic layout of the wiring, I set to reconfiguring the FWD/OFF/REV switch from the 3 phase configuration to a single phase set up. In the previous configuration, there were no motor contactors so the switch handled all of the contacting duties. This was evident by the erosion on the contacts...550VAC will take its toll on any electrical contacts
Fortunately, the switch contacts are very robust and easily removed, so I pulled them out, flushed everything with contact cleaner, and then polished them up a bit with Scotchbrite.

I opted to lessen the load on the contacts even further by wiring all 3 sets of contacts in parallel. At 115VAC, powering nothing more than the coils of the contactors, these things should last for 100 years.
The circuit is dead simple. A common 115VAC (Black) will send power the contactor M1 for FWD or contactor M2 for REV based on position of the switch. There's zero possibility of energizing both contactors simultaneously so I suspect it will work perfectly. The only thing that I don't know for sure is whether it will work for instantaneous directional changes or if it will have to coast to a stop first. I've never been a fan of the instant reverse function, but I've watched real machinists perform it with total impunity while cutting threads. It always felt a little too violent to me, but I'm an amateur at best...
I polished up the fun switch while I had it all apart...

Looks like tons of space to put more stuff to me!

I like the way you think!
