[Fot] Spitfire 1300 Main and rod journal clearances.

[Duncan Charlton]

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).
