Can you build your shop 2’ taller? If so, after inspection put a steel mezzanine in there. My shop is 18’ walls, 60x40. Put a mezzanine over half of it. You can get them custom built to your specs & footprint. PM me for details. Sent from my iPhone using Tapatalk

I've got 5 on one machine. Sent from my iPhone using Tapatalk

Shop is full now. FML. Sent from my iPhone using Tapatalk

Been a while since last post. Work and baby have taken a lot of shop time! I did get the mill up and running. 5 VFD's later. Runs great! The coolant pump seems to be clogged up so I need to take it out and clean it up but everything is is functioning great. Once the mill was running I sprung...

Good call! I still need to iron out details on the cover and fan set up. I'll be sure to have a filter It's crazy, these two VFD conversion projects have me wanting to build stuff just so I can implement a VFD into it. Just a ton of fun and very rewarding.

Thank you! This has been a great project so far. Definitely glad I learned on my lathe (one motor) first. It's nice wiring in all these VFD's knowing it is going to work lol

I plan to build a housing with a couple fans at the bottom to push air into the housing. Excited to get it finished up! Sent from my iPhone using Tapatalk

Making good progress! Still missing the last VFD. Should be here Monday. Old panel Sent from my iPhone using Tapatalk

I decided to rip out the control panel on my mill and run a VFD per motor. That's 5 total. Wolf automation sells teco VFD's for about 130-140/piece. I've gone VFD crazy

That's how I had my Leblond wired simply because I was unfamiliar with VFD's. The VFD ran the shift motor and the spindle motor fine, with the exception of the high spindle speeds. I'd trip a breaker when trying to engage RPMs over 1200. That was a 7.5 horse motor. Obviously I've rectified that...

Is there a good reason as to why I shouldn't run a VFD as a phase converter directly into the original control panel acting strictly as a phase converter, then run an additional VFD solely for the spindle motor on this machine? There was mention previously to not having switches after the VFD...

No worries. What are the benefits to running a RPC over a VFD? It seems to me the VFD's are cheaper now. I ran a VFD directly into the wiring panel of my lathe for several months. Only issue I had was I would trip a breaker on the high RPM settings. That was a 7.5 hp motor.

Seems like I am best off using a VFD sized for all the motors x2 and running it as a phase converter straight into the old wiring panel. Or a VFD sized for all the motors wired into old panel except the spindle and a separate VFD completely Sent from my iPhone using Tapatalk

So would you wire switches after the VFD to power each motor? Sent from my iPhone using Tapatalk

Yeah. It's got 6 motors. 1/3 hp air pump 1/4 hp coolant pump 1/4 hp table feed 1/4 hp rotary feed 3/4 hp spindle 1/2 hp knee I am going to try to put a higher HP spindle motor in there. I'll either have to run a phase converter, or run spindle motor off VFD and replace the other motors...

My mill showed up today! VFD's or Phase converter? FML Sent from my iPhone using Tapatalk

Mill showed up today! Finished the handles for the shift levers Sent from my iPhone using Tapatalk

Thank you! This machine is in phenomenal condition. The ways look like they are brand new. Hardly ever been used. Yep, DRO is definitely next. I have an old Kearney and Trecker rotary head mill showing up today so I'll need to figure out if I want to do a phase converter or VFD (or both)on...

Alright, I am pretty much done with this install. Here's the electrical panel. I cut the face out of the panel for the VFD. I plan to put some plexiglass with cutouts for the fan over it. Here's the manual shift levers. I am making knobs for them now. Here's the front of the lathe...
