I had that picture shortcut on my desktop so I could send it. Then I scrapped all of the shortcuts. Now I cannot remember where I got it. It is on the machine somewhere. I will post it as soon as I find it again.





The degree wheels come from the brand name cam manufacturers.





The rotor is used for laying out ports. It has one corner cut away so you can look through the back of a corner seal hole, and scribe the track of the leading end of the side seal. The top corner you see in the picture, has one corner seal pocket cut open. It is a jig to trim side seals to the correct length. Put in a corner seal in the adjacent hole, and shove in a new side seal. Scribe the back of the seal against the corner seal pocket wall.



Remove the side seal and notch it on a grind stone and clip it off with diagonal cutters. Then square up the end on a hand stone. They are all too long and must be trimmed.

Here is a picture of the rotor with the corner cut out. I put a scribe in the end of the side seal groove and turn the rotor through the port area to lay down scribe marks for the leading end of the side seal. This gives you one limit line on the bridge for a bridge port.
