wheel blocks for those of us tall guys with old axes that aren't adjustable...
So here are some pics of the blocks I use.
The quick and dirty ones that I keep in my case (and a spare set in the car) are easy to make and cheap. Cut (4) 4" sections of a 2x4, then staple some non-skid pads to the bottom and nail a caster cup to the top. Looks ugly, but works like a charm.
