Tools there are many.
Ive always been a person to make what I can and buy a decent brand (cost effective) what I could not
I made my 1st set of hex tools nothing like a good set of alien wrench's,also my turnbuckle tools.1/4" aluminum rod.
Dremel tool with cutoff discs.( you will need to develop a big skill level with this) either you test on old trashed gear as in old radios found in trash or other things.
yes you will need a good set of smaller screw drivers
might also invest in some alien drivers
I always liked a good heavy duty set of Hemostats both curved or straight I have both
wire cutters Heck I used cat claw cutters for years and still do today(when stripping watch how much pressure you us)
a bottle of rapid fix. its a super glue with powdered filler(use when in a jam)
you can go out a spend a few hundred or you can save yourself a lot of cash if you have the skill
a good solder iron and solder I like the 45 watt weller led with chisel tip and 67/33 solder heat shrink tubing
