I have tried to post this 3 times with 6 images and keep getting an error, all within board limits, so I have put the images on photobucket at this link

I have been working on the gear box for about the last month and now have it done and did some testing, here are some of the pictures I have.

Note the through hole in the main shaft, its 3/4 through (over 24 inches) and both ends bored out for linear bearings which is for the pitch control, the fly ball governor will mount on the rear of the gear box and use a 5/8 rod through the main shaft to control the pitch of the blades.

I have also started on the main frame work that will tie everything together and the main pivot bearing as well (which I am also making, buying one would kill this project $$)

There are many more full size pictures here as well.
http://s1186.photobucket.com/profile/methanolcat/index I also have a video of the gearbox chucked up in a lathe, with lathe running at 200 rpm's, that puts the output shaft running at 2880 rpm's.
I ran it for 2 hours with nothing but good results, no overheating or abnormal noises, oil pressure runs about 7 psi and is more of a clogged filter indicator, I put the gauge in between the pump and the filter so a higher reading would show a filter needing changed.
The video is here.

It shouldn't slow me down too much though, there are still lots of small parts I need to make, like a fly ball governor, pitch control parts and drive shaft yokes.
