If I had been there (had a conflict) I would have taken one, as is, it
looks pretty simple to make. Great idea.

Steve,
You gave away at least One. I used it to find TDC on my 13B that
Sunday afternoon when I got home from Paducah, worked great, and confirmed that
the timing mark on the case was in line with the mark on the E shaft.

TDC
Chris,
The attached photo shows a device that makes it easy to
determine the location of the minimum combustion chamber volume (TDC) within a
degree independently of any existing front pulley or flywheel markings.
Connect it to a spark plug location and just rotate the eccentric shaft to the
point where the soap bubble in the clear tube is the highest. It might be
worth a try. I made up a number of these to give away at the Paducha fly
in last summer. The lack of interest was surprising since I couldn’t even
give them away.
Steve
