After realizing the full extend of your dishing tool I am going to say that this Wheel Dishing Tool is darned well designed, compression fittings and all. As far as I am aware, all other dishing tools need to remove the wheel from the stand to check dish.

While Park, Minora, Unior, CyclePro, Wheel Fanantyc all make respectable dishing tools, yours can check the dish while the wheel is on the truing stand. This is an improvement over the dishing tools on the market, as far as I know. All of these tools require the wheel to be removed from the stand to check dish. Perhaps there is something that can do it while the wheel is on the truing stand, but I haven't seen any of these tool companies claim that! For instance, the Park uses a piece of steel bent into a "L" shape. It may be able to do this, but Park makes no claim that the wheel can be checked in the stand.

Anyway, I like it. As far as I'm concerned this is an improvement over existing dishing tools. And the compression fittings seem to be a good way to put some pressure on the brass rod or tube.

The only thing ill-advised is that if you had a Patent Lawyer they might tell you it was ill-advised to post it on the interwebs.
