I drill my own gear (using a KMT Jig) and then have my PSO weight it out. If a weight hole is ever needed, I place it where I want, then have it weighted again. Since I purchase my thumb inserts and plugging needs from the PSO, there is no resentment that I drill only for myself. He does at times, enjoy correcting my mishaps. My span measurements are now dead-on, and more thought goes into my lay-outs as a home driller. Fun hobby - no illegal weights and I don't tell league members what I do.
