I tried a few more thicknesses on shims; I can move the pattern around but it more or less stays in the .070-.080" range. I should try to find a better marking compound as the stuff I am using is not giving a really clear definition. I think there is some 'pull away' when the roller leaves the face of the lash cap and it's making the pattern look wider than it actually is. I can see some faint lines that look like the actual contact but I am not sure. I guess I'll dig out some different compound.
