[AMRadio] Have you got a big knob?

Anyone have, or know a source for, a big knob that would fit a 3/8" shaft?  
Or maybe it is 5/16... seems to be between those measurements.  It is for the 
bandswitch on a European marine HF amp, so maybe it is metric.  I'm on the 
lookout for a 2.5" - 3.5"  knob to fit this shaft and give me the leverage to 
crank the various mechnicals behind the panel.

Thanks for any leads...
