Australian Simplex Auto
- Was interested to learn that the Vizbug right angle behaves well. Have never seen one, but it sure looks good!I was afraid you were going to say the Simplex's cover was part of the
frame. It appears heavy, not just covering material. Am I correct in
assuming that it the loaded spring that allows the slow speed
adjustment, vs assorted weights as used on most bugs?
Bill W2BLCi guess one could say the covers serves as a frame though its only service is that there is a cone shaped almost hole for the upper trunion support. In the eraly ones it is obvious as it is adjustable. In the later ones the only trunion adjustment is on the bottom.The mount for the mainspring, and the mount for the dit spring are both posts mounted on the base. The mainspring is deflected or released by the lever. The dit spring has its own separate adjustment which impacts the dot to space ratio. there is a sliding weight for the speed adjustment, but the mainspring is softer and longer than on a Vibroplex, hence its speed range is slower.73, FD KT5X
