An old thread reopened. I really liked the idea of tcj's shovel tow bar, but I didn't like how far he has to bend over to use it. I wound up buying a tail-picker1 for a couple hundred bucks. It worked OK for several years, but the solid rubber tires really beat up the cantalevered axle frame each time I went over the tracks for my sliding door. I did weld repairs on the danged thing too many times. Here's what it looked like when I finally gave up. It just wasn't worth rewelding any more

So, I went back to TCJ's shovel idea, but thought I'd build one from scratch. So I did a little 3D model that came out like this:

I bought a bunch of square and round tubing and started cutting and welding

I added wheels and a slightly angled shovel platform. The angles of the handle was modeled to match the angle of my Maule rudder. It was also long enough that I didn't have to ben over to use it. I added one of those ratcheting tie-down straps to pull the tailwheel onto the shovel platform.

And the results worked pretty well. The 8" balloon tires really helped getting over the rails for the hangar doors.

Still, there was a fair amount of work pushing and pulling, so I thought adding an electric motor would be a good idea. I'm not getting any younger and my back certainly isn't getting stronger. So I bought a 24V, 300 W motor, battery pack and controller and installed all of that. The scooter's drive gear I attached to the wheel had a freewheel (like on a bicycle) so the wheel could coast moving forward. That meant reverse on the motor wouldn't work, so I brazed the halves of the freewheel together. That did the trick - but the motor didn't have enought torque. The 300 W power rating was at 3,000 RPM. That meant the puny motor only put out 0.7 ft lbs of torque at initial rotation. I put a prybar on the wheel and found out I needed at least 10 ft lbs of torque to get the plane moving. BUGGERS! So, I bought a 48 V, 1 kW motor with a new controller and battery pack. I had to tear off all the old mounts and put new ones on to add the bigger motor and battery pack..

This time it all came together and the tug works like a champ. I added a polarity reversing switch to the circuit for forward and reverse and now it's a piece of cake getting the plane in, and out of the hangar. All of the power set up (motor, motor controller, throttle grip, drive gear etc.) came from the electric scooter market, so parts were cheap. All together, I have about $265 in this thing (forgetting the cost of the failed first motor setup). It was a fun project with happy results. No more huffing and puffing to move the plane around. You can see that I don't have to put any weight into moving the plane forward now. All smiles here. Thanks for the inspiration tcj!
