I purchased a $2500 non running 1977 HLV-H w/tooling. After 4 years of searching and looking, finally found the right one. Here are some pictures of before and after. This took 2 months of clean up. April & May 2016. Before I could even start trouble shooting to get it running.

Varnish, metal dust and dirt was very thick on the lathe, cleaned most off before thinking of pictures.

Lots of tooling

flaking was a surprise.

Finally; It's clean enough to start Trouble Shooting and Researching Electrical. If you are interested in this introduction part 1, Hit the like so I know,

I would like share this learning process from a non running HLV-H.
Thinking of a extra post for Electrical Requirements.

Please Note; I will not have ALL the answers. Just the ones I fixed on this machine. This project still requires self study, research and reading Machinist forums.

Electrical Requirements

Needs 3 phase power to run. I have a 220 volt single phase line in the garage.

First; I needed to understand what 3 phase power was all about so I watched U-tube on 3 phase link below
This gave me a general understanding.

Question - How do I get this to run? The internet is full of ideas. The options I looked at.
1)Change the motor to single phase - Not a good choice and lot of modification to the lathe. I wanted to keep it stock.
2) VFD Repower - Needed to rewire control cabinet. To run Spindle motor, Coolant motor, Speed control motor, and Carriage feed motor. beyond my 3 phase skill set.
3) Build a Rotary Phase Converter. (RPC). - listed as EASY on the web - Nope beyond my electrical skill set
4) buy used RPC from C/L - Never found a newer complete working unit.
5) Static phase converter - unsure about it.
6) Purchased a new American Rotary series ADX 10 HP 220 single phase input and 230 volt 3 phase output.
Lesson learned - 10 Hp is over kill for 1.5 HP lathe and future 2 HP milling machine. I only needed a ADX 5 HP unit that would have saved $600 bucks. The good thing is I have clean 3 Phase power to the lathe and worry free.

While waiting for the delivery I was learning about How to test 3 phase motors. I used this link for understanding the process

The motor tested good. And was cleaned

Removed the "custom" 110 volt outlet from one power leg.

Loose terminals and improper connections. Like a one single wire " One strand of wire" connection on the 3rd leg before the disconnect. Fixed it all. "so I thought"

THE BIG DAY - RPC showed up. hooked it up. Plugged in the lathe and NOTHING I MEAN NOTHING NOT EVEN A CLICK. The only thing running was the New ADX RPC and that was quite.

Called Hardinge for a wire diagram KLA 8220 - NO LONGER SUPPORTED.
In June I had a Clean non running HLV-H and a new Oversized Running RPC.
Next post, HLV-H Non Running Project - Part 2 Electrical Trouble shooting./ What was found.
