This sounds like a cool project. It's really fun reusing and upgrading
rockets. My favorite tool to strip paint is a Makita finishing sander with
220 grit and keep it moving. Some sanding will always have to be done by
hand. I've used a detail sander (triangular pad) with a little success.
I've created multiple hatches on about 6 rockets now including cutting
hatches on old rockets. I use a square piece of the some tube material to
create a template for the hatch. If you try to use the piece that you cut
out for the actual hatch it will be too small for a good fit. If you use a
scribe to mark the location and size of the hatch, it will be slightly
larger than this mark. The cool thing is if you gradually open up the hole
you cut, the hatch will fit nicely with very little little gap around the
edges. Also, talking from experience here, don't underestimate the size of
the hatch and compartment you will have to make. Most of the time, I've
had to create multiple hatches/compartments to hold the batteries, timers,
switch, etc.
The Missile Works PET2+ is a 2 event timer and has safety features. Great
for those future projects. It's about $55. However, it takes some time to
learn the programming steps.
For helping to secure the igniter wires for the airstarts, I suggest Scotch
69 Glass Cloth Electrical Tape.
In my opinion, all complex rockets should have a written procedure and
checklist for prep, arming, and recycling if necessary. Also, you should
have another person checking what you are doing as you load and arm at the
pad.
