Rotary converters are basically a motor with a generator hung on the end to generate 3 ph. power. The generator doesn't lose any power, but the motor takes power to turn, and then produce 3 ph. power. So it's not a 1-1 ratio, since it does use some power to run the rotary converter.

Seems like most here don't like anything that is not made in the U.S.   While I do have a few machines that were made here I found that most are out of reach for me. I have three lathes, all imports. The one that gets used the most is a 14X40 Birmingham that I bought new about 10 years back. For a phase converter I took an old 3 phase motor and and used a small motor to get it started. I have a one way clutch on the starter motor so it does not spin with the converter.  No capacitors and I can run four machines, sometime three at a time. My two mills have auto stop when they get to the end of the cut. I have kicked the circuit braker more than a few times . While my phase converter may not be a true 3 phase power it will give me instant reverse. My two smaller lathes ( 12X36 and 12X37) just did not seem to cover all the barrel jobs.

I too am a fan of the new vfd 3 phase/2 phase speed controllers.  One caution is they are very electronically noisy and drove my Shooting Star dros crazy.

Congratulations Boat it looks like it will serve your own personal needs very well as does mine do for me and all that really counts. 

Very nice looking Lathe!

Boats, if you decide to go to the Electronic 3 Phase system. You need to match the unit to your Horsepower rating of the Motor. If you buy a Static Phase converter and you get one of higher Horse Power Rating it will NOT make 3 Phase power and will pass 220V Single Phase thru to your Machine. It will run but will eventually "Cook" your Motor. Ask me how I know. But with a Rotary system you can get a unit that produces more 3 Phase power than you need. This will give you the option of 
adding more 3 Phase equipment if you choose in the future. The Static Phase system cheats you of power makes you about 80% of your Motors potential. I have both a Rotary and one Bridgeport on the Static system. Mostly because I do not like the noise of the Rotary system. But I have everything else on the Rotary and I can load up to 13 Horse Power accumitavely at the same time if I choose. Hope this helps. Regards, FITZ-G

It looks like you did OK. That Logan will make about anything you want to make and it's big enough to put a barrel thru the spindle. If you should ever want to do barrel work you'll want to replace that tension nut on the outboard end of the spindle with a longer one with 4 set screws in it to center barrels on the outboard end. I can furnish a photo of mine if you would like.

I think you posted a picture like one of my first, you're lucky that drill press and trailer can defy gravity it could have been a heck of wreck... 

Sounds like the load is 80% of trailer capacity?  You still have a safety margin, 25 miles? take it slow shouldn't be an issue.  First recommendation I have for you though is to get rid of the rope, purchase a package of 1" wide nylon ratchet straps, use cushions under the straps under any sharp corners, (ie. old leather gloves work well here).  I'm probably not telling you anything new here.
Just don't hurry and check and double check, go slow and be one of the guys in a little brown derby (that's what my wife says causes traffic jams) and drive like you have precious cargo - which you do.
