[QUOTE="KurtM, post: 1451172, member: 6064"] It will be late next week before I can post any pictures. Basicly I built a ply wood box 2'X2'X4'. put the chrono sensores in the bottom and placed a 50 watt D.C. bulb above each sensor, (got the bulbs from an R.V. store) I then cut up an extention cord and put on aligator clips on the wire ends. I just pop the hood of the truck open, clip the aligator clips to the battery and the lights light up. I went with D.C. lights as they are the most uniform light source. Be sure to paint the inside of the box FLAT BLACK! if not it gets too much light scatter and will only read every 4th-5th round. Then just cut a 4" diameter hole in each end for the bullets to pass through right over the sensores and you are in business. I will post up some pictures when I return to OK. KurtM [/QUOTE]
