I repair my own stuff. Cars. Computers. Electronics. Appliances. House stuff (HVAC, irrigation and plumbing, structural, drywall/stucco, electrical, etc) Guns. Everything. Yay self sufficiency.
I'm very picky too, a perfectionist. Ill buy the right tool for the job if I don't already have it and do it right. I don't just patch the symptoms, I solve the root engineering problem. If I can't do a repair professionally such that you can never tell anything was wrong, I'll replace the item. My goal is always 100% factory perfect or better, no ghetto rigged shade tree shit.
Next two repairs around the corner for me are:
differential carrier bearing - parts ordered ring and pinion bearing and seal set with crush sleeve, axle stub pilot bearing and seal kit, LSD clutch kit and 2 bottles of friction modifier, and 3 quarts synthetic 75W140. Doing it all while it's out.
Keltec Sub 2000 9mm - replacement magazine catch on the way
