f-ing sweet, I wish I had tools like that just laying around at my convenience.

Try having them but to chicken chit to mess with 3phase

[1STGENFARMBOY]

you don't need no stinkin 3ph, just another 3ph motor twice as big as your gonna run.

i can explain.

[Tacoclaw]

This is probably what you're talking about, Dar, we've got a single phase motor running a 3phase, though I have no idea how it works. I just know I have to hold the starter button and kick over the pulley with my foot to help it get turning.


Also, I'm trying a new approach with this build. Blow so much money that there's no way I can't make myself finish it. Ordering a Jungle shackle flip and forward, rear spring hangar setup for 56" Chevy leaves, and I'm seriously thinking about a new Steedspeed with a T4i flange. He only offers the T4i flange in a straight orientation, so it will put the turbo in a position I've never dealt with before, but it's nothing I can't work around.

De-crusting progress tonight, even though it's kinda pointless at this point. Just burning some time.

The exhaust outlet looks to be a half-marmon flange.

[Tacoclaw]

It the outlet on an S400 a half marmon?

[PToombs]

Levi, that's a rotary phase converter. My buddy has one in his shop, but with a capacitor box to start it instead of the motor you have. They make a regular one too, I've seen them on surplus center, it's just a box on the wall you turn on.

I thought a Marmon was a truck? Or a little furry animal?

My shop is on 3phase,I just need to learn how to fool with it

Taco....could you pm me some more pics of how it is hooked up please

[PToombs]

Ellis, that converter is for converting 220 single phase to 440 3 phase power. If you already have 3 phase, you don't need it. Sounds like you need to find an electrician, buy him some beer, and then learn some wiring.

[Tacoclaw]

Or just pay an electrician and don't mess with it. I do a lot of dumb sthi but I don't go near any wiring hotter than 120v, and I don't go near a live circuit hotter than 24v.

I can try to get you a pic tomorrow before I start wire wheeling, that garage was so full of rust dust that it made my flash go crazy in those pics. I had to take the converter pic 3 times.

I seriously think there's more rust up my nose than there is in that frame now.

No i've some smaller stuff to use at the house where there's no 3phase.

I tend to agree with you two,some things are better left to qualified persons

[oldestof11]

It aint the volts that kills ya, it is Volts xAmps that get ya. I have been hit with 240v @ 2 amps. Yowza! I'd rather that than 120v. 120 feels like it hurts, 240 blows up your reflexes to you don't get hit for too long.

I rather run wires than plumb.

[dazedandconfused]

I deal with 120v and 277v at work all the time and that's enough for me.

[1STGENFARMBOY]

I think what is in the pic is a 3 ph motor with a pony start .....you don't need the starting motor you can use a rope like the old
lawnmower engins had.

let me try to explain.

first you need another 3ph motor over double the size of the one your gonna run.
make shure both your 3ph motors are wired for 220/230v
run 220 single ph to your big motor via a knife switch.
it will run on 1ph but it won't start, you need to get it going with a rope or another small motor.
the 3rd lead in the j-box of your big motor needs to go to the 3 pole knife switch of the mill motor along,with
220/230v single ph, once you have your big motor running it will produce a 3rd phase, then simply throw
the switch for your mill power and you will have 3ph.


this is the poor mans rotary converter, there are many different typs of way to convert 1ph to 3ph, but they start around 500-700 bucks.

i will make a drawing and post it up if needed.

Dar

[1STGENFARMBOY]

if your mill runs backwards simply switch 2 leads around this will revers the rotation of any 3ph motor.

[1STGENFARMBOY]

what Pete is takin about is very simmilar to the same thing, but it is designed to start using a large bank of
capacitors to get it going.


by the way 3ph is much much easyer to mess with than single, and when you get over a 3hp motor they are way way cheaper.

just for referance...a 7.5 1ph air comp motor is 500-1000 bucks according to the brand, Baldor is the highest. A.O. smith is a good
motor for the money.
