I spent the last day and 1/2 making the new piece for the Johnson.
I couldn’t wait for the internal threading bar I ordered, but dug around
and found a lightweight, homemade, round-stock, tool with the end
bent 90 degrees and ground for threading. It worked okay,
but I had to make very light cuts.
The piece threads on real nice to the prop shaft gear threads,
so I was happier than a June groom.
I tried to make the piece a little "beefier" than the original,
but spend most of today "nipping and tucking" to get satisfactory
clearances.
As I was playing with all the parts, tipping the gear case "cone"
upside down, the little nickle sized slug (that goes between
the adjustable thrush washer/ bushing and adjustment thread)
fell out, and was never seen again. After crawling around on
my knees for ten minutes, I fired the lathe back up and made one
of those, lol.
All in all, it was a fun project, but don’t think I’ll going in the machining
business anytime soon.
