I've been using a towbar a guy ordered from some outfit, like the 'towbuddy' or something like that from Aircraft Spruce. It works quite well. It picks the tailwheel up off the ground then you steer with the towbar and its own wheels. I needed something to get in and out of a t-hangar by myself, and this has allowed that. Very maneuverable as well, I only have 10" or so on either side of my tail and I have not had a problem. Another guy just made for me a towbar that is very inexpensive if you have access to a torch. It is basically a t-handle with two long bars extending out like scissors with a slider inbetween that when slid down closes the two bars together. At the end of them are two open sections that fit over the tailwheel attachment bolts in the center of the wheel, then just move the slider down until the bars squeeze onto the tailwheel bolts, and push/pull away on the aircraft's own wheel. I know, not great in description, but I'm not sure I can link/post pics here. It literally cost a few dollars at most in material and some acetalene. The towbar and a paint mark are working for me, but I like the idea of a channel or track if using the aircraft's tailwheel, would have to be paint with the 'towbuddy' bar.
