8 MAY/JUNE 2022 SPORT ROCKETRY as of March 2021 at the local Home Depot, and ordering the top of the tripod direct- ly from FORMUFIT, since at this writing it was not available from Amazon. is pad is easily set up and taken down at the field, and the only tool needed is a standard screwdriver for use on the hose clamps that attach the rail. Tools needed to build this pad are a drill with 5/32" and 1/2" bits, a saw for cut- ting plastic pipe to length, and a 1/4-20 drill and tap set (and a tap handle, of course). It is helpful to have a drill press to help get the hole through the top of the tripod top piece well centered. In addition to the materials listed you need pipe cement, preferably the "all pur- pose" type which works on both PVC and ABS.

A little liquid thread locker for the nuts on the blast de- flector/rail button assemblies is also a good thing to have. In my area (south of Seattle) I have much better luck getting these parts (other than the FORMUFIT fitting) at Home De- pot than at Lowe's. Ace Hardware might also be choice. Tripod Build First, cut one 30" two 20" and three 2" long pieces from the 2" pipe. e 30" piece is the fixed-length leg. e 20" pieces are the upper section of the two adjustable- length legs and the little 2" pieces will later be used to join threaded adapters to the FORMUFIT 3-way elbow. Chamfer the cut is quite a bit less expensive than the same sizes in PVC. It is also lighter weight but still plenty stiff. e fittings, however, are PVC, so the all purpose cement is the way to go. I don't bother with primer and such, since all we are using the cement for is to
