I've spent a couple of day's working on the machine now since the gears arrived from HPC. I had a last minute change of mind and increased the MOD of the gears to 1.5 on the first stage and MOD 2 on the second as opposed to Mod 1 and 1.5 respectively. Looking at them now I think it was a good idea!

The bulkheads were just a fraction too large to fit on my mill, so Kane and Ant were able to machine these out for me from the CAD files I sent over. They've done a great job.

As you can see above the main gears are mostly machined out and have keyway's in. There's some lightening holes to put on them still but that will be done tonight. Test fit of the weapon motor, gears and prototype cam's all seem a good fit.

I'm now machining the gear cover that holds the bearing for the shaft on the first stage of gearing.
