Thanks for the added information and picture. I'll have to keep my eye open for a gearbox similar to yours!


Dave, try to get a gearbox with minimal backlash or you might have to do this as well:

The gearbox is a 'Reynolds' brand, fractional HP size, input shaft 12mm, output shaft 16mm diameter. Also look for a tapered roller bearing (I used an used one off my Landcruiser) to take the thrust load off the gearbox. It just needs to be beefy and in reasonable nick, the thing only turns 15 degrees every hour after all.
