OK, here are some pictures. I used 3" pipe for the centers but if I had it to do over I would use 4" as I think it bends the lead to tight. I would also shorten them to 10" instead of 12". I'm still working on a lock system as you can see I'm using really cool tracer wire right now. Also when you put your hubs together make sure the bearings are fairly snug as this will help to keep the lead from unrolling to fast. Knock the studs out of the hubs and put them in backward so the smooth heads are toward the leads. I used a flange insulator kit to insulate the bolts on the axle ends, and cut some PE pipe to insulate the whole assembly from the stand. I ran short jumpers from the machine to each reel and bolted the lead to the reel. Each reel is hot but insulated from the truck. Hope this helps. Let me know what you think.
