Ah, tho ol' turn your wall into a drill press trick! I'll definitely give that a go.
In the mean time, now that the booster tube is on and the PPD is on, time for the frame. This is a Nickatron frame and it looks fantastic! Besides a cleaning before paint, there is nothing I need to do to prep or fill or anything! Beautiful! Let's hope I don't screw this one up!
Don't worry, I don't think I did. Until Julz tells me it should have a certain degree to the angle it sits or something. Just kidding Julz! I always welcome your insane knowledge of all things detail! I have some new screws to mount the mobo to the frame too that should make you proud! But all in due time.
I started by drilling out the holes. I'm going with the larger 10-32 screws in mine.
After a long search and lots of reference photos (mainly from Julz's thread TBH) I found the center of the tube. Then I did a dry fit of the frame to allow the right height and clearance from the PPD. This time I did it a little different. I did mark out the holes the same.
It's a little hard to see.
Then I center punched the top hole. (I may have already done that in the above photo.)
The I drilled out the hole to the size I needed while the tube was still mounted.
I had already drilled out the holes in the frame so I put the tap through the frame (not to thread but to guide) and then I tapped the top hole with the frame as a guide. I had no idea if this was going to work with my next step.
Frame with 1 bolt attached.
Now I lined up the frame where I wanted it to be again, and with the frame still there, I punched and drilled my holes into the tube through the frame. Cleaned it up and then I tapped, again through the frame using It as a guide not threading, and low and behold, it worked! No worry of not having the perfect distance between the holes this time!
Test fit of the bolt.
Then I installed the bottom bolt, washer, and the cable clamp.
And one more close up because I'm excited how this turned out.
(Photos are crooked, not the parts, just saying.)
