FIRST CUTS FOR THE CRANKSHAFT BEARING AND FINISHED CONNECTING ROD WITH PISTON
Here is the method I used to pre-cut the pieces for the crankshaft split bearing
I used a stub arbor in the Mini-Mill and a .025 thick slitting saw, to cut a slit in the end of a bronze bearing rod.
I then fastened the bronze rod in the slot of a quick-change tool holder (it just fit!) and sawed the piece off using a slitting saw chucked.in an arbor in the lathe chuck. The bar could be moved vertically, to assure a flat bottom .
The split bearing was completed, along with a bearing for the piston.
The split bearing really gave me fits . . .the soft solder joint broke twice, so I ended up Silver Soldering the pieces together. I sand blasted the rod to produce a nice matte surface finish.
The finished Piston and Connecting Rod. I am not sure If I will use a ring, since the piston has such a great fit in the cylinder, compression will probably be adequate without a ring.
