Ok I'll toss this attempt into the mix. The little rocker engine
Two whole pieces complete, weekend project?
The axle and crankdisk, small, tiny, need new glasses
Dont want any tool envy going on now
First shot drilling the holes in the disk with my fancy dancy cross slide
thing-a-ma-bob, it works
Second cutting off the excess to which I dropped the other piece and spent 20 minutes looking for it. Of course it found that little space between to lathe stand legs and floor bolt down bracket. All nice and cozy it was too, just a-sitting there watching me hunt
Third shot facing the disk down to finish size, Yes there is a part down in there
Final first 2 little pieces. Photos don't do it justice. that is a small little engine.
