      So true Bart. I don't design as much as bump into things. If there is any 'skill' to this, it's the ability to separate the chaff from the wheat. There are so many wrong turns till the right path reveals itself.

          • In eager anticipation of the arrival of the NEW SD from Dave, I have been finalising the gearbox design for the contra-rotating props. This is it.

            There are two ways to go here. Either a series of bevel or mitre gears like this set up, or a gear cluster using double gear cogs. The former is simpler the latter is better - if you can find the approipriate cogs. I couldn't get hold of the damned things so this is what I'm going with. And it works incidently. I'll cast up some props tomorrow and report back (from the hospital, probably, where I will be recouperating from the third degree burns). I love this hobby.

            • The gear box looks good, but keep in mind that there has to be a sizable amount of 'slop' between the gears as they are working in an incompressible fluid. If too tight your gears will be water hammered at speed and will bind up, or at best, will present an unreasonably high torque load on the drive shaft.

              Just about done with the BALUGA SD's. Should have them done and tested mid-week. Then off to you and Bart.
