This discussion group is for all you gear-heads, techno-nuts, tinker freaks, backyard airsmiths, engineers, machinists,
miscellaneous do-it-yourselfers and any other mechanically enlightened gadget junkie that enjoys working on paintball equipment.
While we would prefer to keep the topic focused on purely technical matters, please feel free to discuss anything paintball related that may be of interest.
Many questions have popped up repeatedly- They've been archived
for your Tinkering pleasure in both the Frequently-Asked Tinker's (FAT) and the Rat's Nest.
