First good 6-1 run
« on: September 24, 2018, 09:02:42 PM »
I had my first good run with my Listeroid 6-1 Saturday. I call it a huge success, the culmination of many hours of thought, elbow grease and studying the wisdom of others. Particular thanks to George Brekenridge.

The 6-1 is coupled with Harbor Freight 10KW, 3600rpm, 2-bearing head. It was found still in the box on Facebook Market Place for $200 at an estate sale. While the 6-1 will never put out much more than 3KW at the reduced power it should outlast me. This simple, unregulated brushless head handles the unbalanced 120V / 240V loads much better than the 3 brush type Chinese ST-5 heads I tried.....

The rudimentary flywheel balancing / equalizing I did two years ago is pretty close. It tends to slide a little bit under a 2500 watt load, but that might be because the governor is drooping 8hz from 62hz at no load to 54hz at 2500 watts...... (In the picture it shows 61hz at load, but that was after a manual adjustment.)

I'll work on the governor next.......

I'll add the pics tomorrow after I rotate and size them for viewing.  I'll still need help with video.....

Hi Barenburg, and welcome. Much easier to post a video on YouTube and then post the link here.

Looking forward to it,

Bob

I really like your balancing rig.
Did you find that the wheels were out of balance by very much?
I have pondered doing my flywheels also because the rig starts shaking at 700 rpm.
(Mine is a 900 rpm GM90 version which I currently run at 550 rpm).

nice work!

Thanks Veggie.

They were very crudely cast and just over an 1/8 inch different in diameter.   The pictures you see are after I stripped them and ground away as much flash as I could.  I think one of them took about 7 oz of lead to bring the counterweight to bottom center.  The other was about an ounce more.

Then I mounted them on the shaft 180 degrees opposite.  I believe there was another 3-4 ounces of lead added to the lighter one in the counterweight area.  When I was done they would stay at any clocking position I chose.

At the time I thought I might have to add or remove lead to fix a hopper or slider, but today I'm thinking ok as-is.

I still have the the bearings and shaft if anyone is interested......
