Here's some I've gathered here & there:

I like to use my wife’s old fingernail emory boards as well as new boards to sand with. I especially like those big thick ones (7”x3/4”x1/4”) with different grits on each side. You can find them at any Wally World.

I like using old toothbrushes (with all the rows of bristles removed except for the ¼” nearest the tip) to spread glue at the proper distance for the deepest (front) motor mount centering ring. I measure the distance from where I want the glue, mark the toothbrush the same distance from its tip, apply glue to the bristles, insert the toothbrush carefully to the mark, and start twirling. Usually it takes multiple passes for a uniform layer of glue. The toothbrush lasts a long time regardless of the glue used (except CA - which I don't use for motor mounts anyway) as long as you clean it immediately.

I also use old toothbrushes in the field to remove motor residue (and myriad other uses EXCEPT for brushing my teeth - I hear BP residue tastes nasty…)

For really short motor mounts in small tubes (bt-5, 20, etc), I use a Q-Tip in the same way & just toss it when I'm done.

I "borrowed" this idea from a fellow (Randy Boadway) in our club. I use those Sterlite plastic storage boxes (again obtained at any Walmart) as a single “project box”. When I’m building, I generally work on more than one rocket during multiple sessions. I put all my parts, instructions, decals, etc in this box, put on a label, and stack it when I’m taking a break. Makes for a bit more order on my workbench chaos. I use three basic sizes tailored to the size of the largest built-up piece - small (1”x6”x3”), medium, and large. These boxes are cheap, stackable, and transparent. Also great for club build sessions and transportation.

I saw this a while back on EMRR – works like an absolute champ! To hold your body tubes when putting on fins, use Legos! Use the gray, wide base - doesn't need to cover whole rocket, just a few inches past the fin area. Build up the sides as close (you’ll generally be within 3/16”) to the sides. Build one side up & over the BT, a little longer than your fin. Legos are cheap, square, straight, easily reconfigured, will keep your fin at an absolute right angle (or not, if needed), and can be tailored to your rocket’s dimensions. It’s hard to explain, but try it – it’s very intuitive & flexible.
