I finally decided to get the Tire Razor a couple of weeks ago and I like the way it works with an exception or two. First, why in the world did they decide to use a grub screw that doesn't use the accepted standard wrench for 1/32 cars. Nor does it use the size that I use for my 1/24 cars. When I realised this I knew I had to watch closely to not misplace the wrench. Well it happened anyway and it took me several hours to find it.
Second, is there a way to adjust separately the position of the piece that lowers the axle? As is the left side is 1mm lower than the right. I have reversed the bushings and the result is the same. So now I am down to truing one tire at a time.
