pin holes are common. Most mirrors will show pin holes if you hold them up to a strong back light. Older mirrors will have more and/or bigger ones. If the mirror looks good from the front with no film, then I'd bet you wouldn't know the difference in a side with it recoated (if you could do that). See if you can do a side by side comparison with another mirror close to the same specs. So far, I haven't had a mirror recoated - but I'm not proud.
Are you using plastic strips for spider vanes? They look like clear plastic strips. I'm not sure I'd trust that over time. I'm not sure I'd trust that over primary.
Good info about the pin holes. I am not going to rush to do anything major. I discovered a few pieces that I am missing, so it might be awhile before I can test it out; especially on the original mount. I am missing the tangent arm, the cork clutch, and I need to clean up the threads for the long thin bolt that holds the forks to the tripod.
Here is a better picture of the material I used for the spider vanes. It is not plastic, although the pictures do look like they could be. It is a shim stock sheet that actually came with the scope. It is .005" thick.
It seems to be exactly what is needed. I cut strips that were 10 7/8" long by 5/8" wide. That size seemed to work perfectly. I still need to get the secondary perfectly situated, but might have a few things I want to do before I finalize its position. I have limited experience with newt collimation, and what little I have done has not went perfectly. The vanes, though, appear to be uniform length all the way around. I measured from the collar where the vane wraps to the center hole on all four. They might vary a total of 1mm between the 4.
I put the scope back together, because I am pretty much out of time for this go around. Hopefully I can find a tangent arm or get dimensions to make one. Other than a more thorough cleaning/greasing of the mount, paint touch-up, and a few other tweaks I am sure, I think it is pretty good. Far closer to the sky than it was a week ago.
