I fooled around on my CAD program tonight and made a full circle degree wheel of about the right size for our little engines. The automotive ones available are a bit too big. I hope it uploads in full scale. It's 6 inches in diameter. Let me know if it bombs.

To get it to print full size:

click link for full size below thumbnail in post. It will open in a new tab in the browser
save image
print image directly from file folder where you saved it.

That worked for me anyway.

I was not happy with the jagged lines of the previous wheel so I've replaced it with a high resolution version.
