Bud,

I made my own degree wheel from a piece of flat aluminum stock and a glued-on 
paper degree wheel that I got from one of the performance parts houses ? 
Summit, Pegasus, etc.  The hole in the center has fit the pulley bolt on the 
engines I?ve worked on lately (including a TR motor).  I also had to do an 
initial check without removing the pulley, so I got some strong double stick 
foam tape and pressed it into place.  I then checked for true TDC and bent a 
temporary pointer into position.  I was able to check cam timing that way.

If accuracy counts, don?t photocopy someone else?s degree wheel ? that can 
create a distortion so that the timing figures can be a couple of degrees off 
in various places around the circle (I found out the hard way some years back).
