I imported a compressor from Jim about 10 years ago, it went smooth but I was nervous I would lose the whole thing. I wanted an electric start compressor , ha ha... what everyone said is true about fees... I thought I knew what it was going to cost me and ended up costing me another $200 in fees I didn't expect. I bought some spares from Jim about 5 years ago and it went smooth but not sure if he's sold any compressors to the US lately.

On a side note, oversize your wire as well. Seeing as you have a 20 KW head which could potentially deliver 80 amps at 240 would be #4 AWG copper (70-90 amps depending on wire type). Since you can only generate about 9 KW with the 12 HP that could deliver about 38 amps and would need a wire size of around #10 awg (30-40 amps depending on wire type), you may want to go somewhere in between sizes. I would do at a minimum a #8 if not a #6 between your generator and your transfer switch depending on distance. The increased wire size will help prevent voltage drop or sag with a heavy load inrush.

Butch is absolutely correct on oversizing the gen head. I run a 15KW head on a 8/1 knowing I can never produce 15KW but starting currents and inrush is never a problem. The extra mass helps ride through those starting currents much like a large flywheel.

Agreed, the website is appreciated and most mornings during coffee it's one of blog / fourm stops. I was worried when it went down last week and hoped it would return.. many thanks.

That book appears to no longer be available on Amazon or anywhere else. I've wrote George a couple times in the past about the author but George hasn't replied. Had a member of this fourm look in his copy for the author's address with no avail. I think several of us here would be interested in a reprint if he ever decides to provide them in the future.

Things I want to Buy / 11" ST pulley
« on: July 03, 2023, 07:32:22 PM »
Looking for a 11" "L" belt, 8 rib solid pulley for ST Gen head, for a taper lock (no need to include taper lock). Checked all my sources and none available until they order another shipment from India and my India contact hasn't replied.  Lathe is down at the moment or I would turn my own. IF anyone has one laying around they could part with, please drop me a line.   Thanks.

Crazy isn't it ? , All that technology for $14.49 free shipping.

Powdermonkey is right, buy one of the combo hertz, voltage current or hour meters for cheap and you can see what your unit is doing. I have some of these neon lamps in a yellow 1/2" mount case if you want them, I'll ship you a couple. Nothing wrong with KISS (keep it simple stupid) method.

38ac, I can go out and check my ST head in the morning but I think it what they call a NE2 neon bulb. I might have some in my part drawers. I send you some if I have them. Probably something like this:

General Discussion / Re: 6/1 generator build
« on: May 26, 2023, 03:13:45 PM »
After ajaffa1 mentioned 6/1 and the 8/1 I was thinking about my Automann 8/1 flywheel remembering they were bigger. They are 24" flywheels so I need to find a 11 1/4" pulley for that engine. The Automann needs going through and I was told by someone that these engines were brought in for the Amish and usually abused. I might see if I can get on Butch's rebuild waiting list and take it down to him for an overhaul.

The controller I was planning on using is a PLC (programmable logic controller) left over from an electric project I did. Probably either a small Allen Bradley or Proface I have laying around. They are basically an industrial micro like the ones I use in my other life. They have analog inputs as well as discrete inputs and simple to program.

If you are into arduino, Automation direct now makes an industrial version with modules and cards called Productivity Open. They're nice because there's no soldering, and open circuit boards and they clip on a DIN rail and have terminals.

Yep, have it covered with both a 8 1/2" and 9 1/4" pulley for both 6/1 and 8/1.  Long term will probably automate the start / stop with a micro controller and monitor speed and temperature. I think BruceM did something similar to his. Too much on my plate at the moment, trying to get a barn concreted with PEX in the floor, designing and building a tilting pole structure for two solar arrays with 12 panels each, getting power trenched in back from the main road and clearing trees for a house maybe next year. Gets harder to do every year as I get older and I'm over 60 now.  This Lister project is more of a fun project than work with a future purpose to me.

Yes, everything is oversized like the 7.5 kw gen head and I have a 8/1 that needs gone through that I'll swap out at a later date. Figured I would get the bugs worked out with this build and provide power to the barn until I can fix the 8/1 in time. Plus the 30 amp plug matches my 7kw  3600 rpm screamer so all the plugs are identical.

After running out of Argon and getting a new bottle I finished up the engine mount while fighting the wind blowing my shield gas. Removed the Generator dog house and will pull wires up into a control box with the exception of the bridge rectifier. The control box will have a contactor, breaker and voltage monitor relay along with Current, volts, Hertz, and hour meter. The voltage monitor relay will pick up the contactor when the generator voltage is within a good range (probably 210-250 volts) and drop out outside of this range. This is to drop out the generator on a shut down with a load to save the charge on the field. Bottom of the box will have a 30 amp twist lock plug to plug my 8 gauge SO cord in to the barn.

General Discussion / 6/1 generator build
« on: May 23, 2023, 02:35:16 PM »
Picked up this 6/1 last fall, started cutting and welding on the frame to mount a generator and move the engine. Lots of adjustment on the generator base. Strut in both directions plus a slide base for belt tension. I have several various ST heads and L belts so this will accommodate any head and take anywhere from a L91.5" belt to a 106" belt.  Putting the 6/1 in the center of the frame so I can place a mill on the other end for grinding wheat and corn off the second flywheel.

You have a beautiful engine shed butch, love the rough sawn lumber. I missed an opportunity to buy a variable speed carriage belt driven mill a few years ago to belt up to my rumely. I have 17 acres of woods and a saw is on my wish list so I can do a proper engine shed.
