So, way back when, in 1974, Edson built a pedestal that was supposed to fit a Ritchie compass. The top plate had 4 ¼" countersunk screw holes facing down in a diagonal pattern to fit the ¼" x 20 threads in the casting of the pillar. It also had 4 #10 or #12 countersunk holes facing up, presumably to act as studs to mount the base of the compass.
Problem is, the holes facing up are not symmetrically drilled: 3 line up with the Ritchie base, and one misses by ½ a screw hole. So, Edson suggests, just use the downward holes to hold it all together. Problem is, Ritchie and others say to remove the compass during winter storage, so then the whole assembly can come apart. So what gives? Alex Giannelia CC 35-II 1974 to be renamed after re-launch TORONTO, Ontario ag@@airsensing.com
