Yesterday when I got that CI stove door from the neighbor , I also loaded
up his hand cranked forge blower . I've got it pretty much stripped down now
and Houston , we have a problem . There are some gears in the drive ,
straight cut spur gears and one helical ... and the last gear in the train
is a small helical and it is badly worn . This gear is machined on the shaft
as one piece as far as I can tell , and I'm very doubtful it can be replaced
.. I'm not sure just how old it is , but he said it was his grandfather's
blower from his coal forge - which the guy also has in his shed . Any chance
one of you guys has a source for parts for antique forge equipment ? If I
can't replace the shaft I guess I have a couple of options : I can very
carefully TIG up the teeth and hand fit the gear , or if I can find a gear
with the proper pitch and angle I can fab a new shaft .
Everything else is just straight replacing screws and machining a couple
of bushings .

Not up to learning to cut gears, starting with small finicky ones?

If you can get the shaft out as a bare item, could you weld up the teeth
and trade favors with someone who _can_ cut gears?

Or if you're really lucky, you could find a mating gear to put onto the
shaft (assuming you don't have to cut away too much of the shaft to do
it).

Tim , I have no problem cutting straight cut gears . In fact , a couple of
the gears in my lathe QCGB were made right here by yours truly as were the
gears in this 9:1 reduction set .
http://s991.photobucket.com/user/Sna...?sort=3&page=1
which is closer to finished than those pice show .

Helical gears are an order of magnitude or two beyond what my tooling will
do . I have no way to rotate the work in synch with feed .

I would check ABANA websites...many local groups across the country. Might want to google the manufacturer of the blower and see what ebay has for sale. I look under "blacksmith tools" on occasion. I would think there is a pin holding the gear to shaft. Best of luck.

You wrote "helical" and it turned into "bevel" inside my head. Probably
because I'm an engineer doing accounting (1st day of the month is Billing
Day) -- trying to do financial stuff always scrambles my brains.

I wonder if someone over on the Gearotic forum might be willing to help
http://www.gearotic.com/ . I suspect you'll have to sign up and post a
message and see what response you get. Obviously you would have to
identify the gear DP/module and helix angle.

The blower was made by Belknap Hdwe & Mfg Co , which means it was made
between 1907 and about 1940 - and I was mistaken , it was originally the
neighbor's great-grandfather's . The mfr is out of business and I can find
no reference to their making forge blowers . The gear is definitely not
pinned , the minor diameter of the gear is the same diameter as the shaft .
It's looking more and more like I'll be doing some delicate TIG welding ...

Toss a couple pictures up. There are folks who make parts for specific
ones but you need to know who's blower you have.

The Buffalo company is still around BUT they don't carry parts for the
old blowers.

If you don't expect to use it a lot you might be able to build up the
gear with a torch and brazing rod, although TIG is nice for free-hand
sculpting.

Perhaps you could take an impression of the other gear rolling against
a warmed wax or hot-melt glue blank, mold a negative of a tooth on it
in fireclay and use that as the mold to fill in the worn teeth. Even
95/5 solder might hold up well enough for a while as gear teeth, I've
used it to cast tooling fixtures and it's hard enough to take threads
reasonably well.
