suggest that a vari-speed, or speed-changer as I think it was called when introduced in the 40's, will slow a bug way down, especially on an old racer with a U-shaped damperm which allows it to lay straight back if desired. I put one on my hyper-active 1941 blue racer deluxe, and it now goes from 15 wpm to 40 wpm with a flick of the wrist. 72, Fred KT5X (w5ya/qrp) K2 # 700
