View Full Version : Mounting VFD on mill

I'm approaching the completion of a fairly major project, mounting a Bridgeport J-head onto the overarm of my Victoria U2 horizontal mill. I have a VFD that I plan to use to run the motor; I have 3-phase from a RPC but seeing I have the VFD to hand I'll use it for the convenience of variable speed etc. I'm toying with where to mount the VFD, wondering how others have mounted VFDs on their mills. I have the DRO on an arm on one side of the machine, plan to put a panel with MachTach plus VFD controls on a similar arm on the other side, but not sure where I'm going to mount the VFD itself. How/where have others mounted theirs?

When I did my Bridgeport clone I used a cut down computer case to put the VFD and other electrics in and I mounted it on the right hand side of the column. It would probably need some sort of guard if I was going to be using flood coolant but at this point I'm not doing that so I haven't worried about it. I have a remote speed control pot, start stop switches and For-Rev switch mounted on the LHS of the head where the original forward reverse switch was.

Any chance of some pics of your mill, please?? I have a similar mill and wondering what else you have done to it.

I'll put some sort of thread up when I complete the conversion, but here's a couple.

More than a few hours have gone into hanging that thing off the overarm, everything else has been neglected for several months. Getting close to running it now. I have the vertical attachment but the lack of a quill has been a major drawback.

I actually thought mine was similar, BUT it's that old, I think it was used to build the Titanic or maybe it was the Ark. I can't even find any pics of it on Google!!!!!
It runs flat belts and has a single overhead arm approx 60mm diameter, and a number3 morse taper!!!

Kryn. Sounds like you should post up some pics of yours - maybe a new thread. I'd like to see them as I'm sure others wold too.
