I'll be using the awesome Bigi330 shell. Here it is straight from the box.
Also included were all types of shiny aluminum goodies.
I wasn't quite sure how to mark and drill the holes for the Ion arm so I took a small piece of cardboard and placed it on the back over the mounting holes. Using a pencil, I made a quick rubbing to show the hole placement.
Then I simply drilled the holes and tadaaa! Instant template.
After drilling a few more holes I realized that I wasn't 100% sure how exactly the PPD and the booster tube were attached, so after a quick PM to Vin, he gave me some tips. (A lot of you proton pack pro's probably already know this method but I'll post up the pictures of how I did it to help out the other newbies.)
For the PPD, first drill some holes in the center of the curved area.
Next, center and tape the PPD to the shell.
Flip the shell over and drill into the PPD.
I used a 13/64 bit (i think you can also use a #7), then tapped for 1/4-20.
I used the same method for the booster tube.
Thanks for the help Vin, you rock.
If anything looks off please let me know. I'm always open to suggestion.
Next step, chopping off the N-filter for the aluminum one.
