Trigger Pull gauge-cheap & accurate

Another post asked about trigger pull gauges. -
Repeat info: - Get one of the $25± spring gauges(mine's the RCBS).-Put a strip of tape on it. - Find a set of official NRA weights. Lift each weight - mark each weight on the strip of tape.  -- My RCBS factory markings were/are almost ¼ lb off.

Then put a DA label 80 on it. (calibration sticker)

Homemade trigger pull tester. Coat hanger-light weight tin lid-4-1lb Lyman bars-1 box 240gr bullets=Trigger Weight Tester. The coat hanger must rest on the trigger at the same area each time, or reading will be different. Get close with the 1 lb Lyman bars, then add 240gr bullet, till hammer drops. I did get the 1lb bar weight from a good scale.
