Ok, OK, I just felt like I was being "hung out" as a sign of what not to do.
At the time I hadn't heard of VFDs nor had I heard of the smooth running benefits of 3 ph and even a home brewed rpc would have required some expense. I had the single phase motors in "inventory" so it became a simple choice. I have had satisfactory performance out of what I elected to do at no cost beyond the work time.
If I were to come across a 220V 10hp 3 ph motor as a basis for an rpc I would consider making one and re-installing the original motors (I throw out NOTHING so of course I still have them).
It would however be a low priority job and I'm fairly backed up with projects and seem to complete them at a far slower rate than I used to.
