Motor mount v2!

Who said you cant place a 44 can under the spur gear in a standard savage?

Found a sheet of 2mm stainless steel. Bend it into a U shape that fit inside the TVPs. Did a few test bends in order to get the right fit. Made a slot in each side. The gear mesh will be adjusted by moving the mount up and down.

Metal bend into shape:


Cut out in order to make maximum room for drive & spur axle:


Here you can see the slot. Placed a washer on each side of the mount - it slides quite neatly. I dont have a ton of adjustability... but I can gear this guy from 40-55ish MPH with a 47t spur (not counting ballooning in).

I had to grind away a little of the center gear box - The area where the top screw from the disc brakes were inserted. Other than that the opperation was pretty painless... the hardest part was drilling in the titanium TVPS. I increased the screw size at the mount from M3 to M4.
