even the most worn canon pinion on the sea wolf can be tightened
for best hand tool locate a “cutting” tweezers. tips are flat with toe nail clipper look
dull the cutting edges. place pinion on dull broaching tool near half position
tighten with squeeze of tool
search ebay + broaching tools-then use some fine metal sanding paper to dull the 4 cutting edges
place pinion over appropriate dulled broach then gently place tweezers over pinion staff ( half way) and squeeze.
A filed & dulled toe nail clipper works also. key is that dulled steel broach inside the canon pinion tube
note: filing and dulled that toe nail clipper is a must. you want to trim it.
i used a flex shaft with disc sanding pads. tit has to be thin, and the “cutting” edge even thinner with it dulled
i actually made a rounded edge top/bottom that hols the pinion!e
to insure you do not tighten so much that the broach remains in the tube
use some ingenuity – found a tiny rubber block and mounted it so you cannot tighten the tool too much
like my jewelers trick for clasps that wear out and can no longer hold, heat does not work cause it makes the softened clasp even softer. hardening the entire bracelet can cause solder issues. a new one can be 100.00 with soldering fess.
i began placing a rubber band over then under the part that slides through the lock.
these freely “repaired” clasps lasted longer than the original lock.
note- you cut both ends of the band – the par under cannot be seen except viewing horizontal close uop
the bend of gold now stays up and squeezes down into the lock
INVESTING IN THE CANON PINION TOOL
an actual tool to tighten canon pinions exists. used watch parts dealers have them
it is a steel tube w/round steel base. a softer steel tool is set with a notched “v” at its top
across from the V is a hole cut through the tube,
looking through this hole you see it lines up with the notched tool
place the canon pinion over an appropriates broaching tool.
slide the broach w/pinion through the hole and then over the V
allign it appropiately.
the area that must be “pinged or dimpled is usually the center of the pinion.
canon pinions have hardened areas at top and at base where the gear is
canon pinions are heat treated and are brittle by nature
you want to just tighten the “clear tube” area.
with tube area over the tool, you drop in the second part of this tool,
a steel tool that slips into the top of the tube and comes to rest exactly over the V portion of the tool.
if you have your pinion resting correctly, the tool will be over the appropriate are.
now, gently tap the tool going through the tube
i use a brass/plastic hammer
about 10 inches with small brass head and plastic head
light weight so unless i am swinging it kike a roofing hammer
one bip or two does the job
you may want to expirement with old pinions
