Speaking of Christmas, I have a Christmas cactus that my mother bought

Does "I could have had but decided against it" count?
When I cleaned out Grandpa's shop last year I could have kept his table saw, which easily dates back to the 40's.
This one looks brand new compared to Gramp's unit, but the style is the
same, right down to the bench top that it's mounted to.

There are a lot of states that way. NY and PA come to mind. Actually,

I have a rock. It's gotta be at least 100 million years old.

I've got a circa-1980 Skil Xtra Tool. 3/8" variable speed drill with 3 settings: Drill, Hammer
Drill and Hammer Only, also known as chisel mode.
It came with some long bits that you could (supposedly) use for scraping paint, cutting
grooves, etc. when in chisel mode.
https://www.terapeak.com/worth/skil-xtra-tool-600-corded-hand-drill/191723132907/
I used to work at a company that had point-based safety program. There was catalog
of stuff from which you could redeem your days-witout-an-incident points or points earned
for reporting an unsafe situation. That's where I got the Xtra Tool.

My dad used to work for Western Electric back in the lat 40's and early
50's. I inherited his company soldering iron and it has to be at least
63 years old, he no longer worked for Western Electric when I was born.
My oldest power tools that I still have is a B&D drill, I got for
Christmas, when I was 13.

Regarding the motor gear: the other option you have is to grind off the
gear teeth and start with a smooth shaft. It'd be much easier to cut a
gear with that bore than it would to cut a gear on that shaft.
Especially if we're talking about filling in new metal, where there's
very little chance of things being a consistent hardness.

I don't have any really old tools, but do have a couple of 50 year old
electric appliances. Age alone does not make them unsafe, usually
mishandling of cords causing them to fray or crack where it bends.
Check the insulation. Of course, tools stored in a damp shed or garage
may be damaged from years of corrosion and bearings can dry up.

That sounds doable for both 3D printing and flat milling. Most gears are
hobbed from rod, but you can also just cut the gear from flat stock using
a mill.
3D Printing:
Shapeways can probably do that, all you need is the file. (I have not
tried this, but it looks like you'll be well within the capabilities of
their machine.) Here's the trick: That OD is not the OD the gear goes
by. You need to figure out the pitch circle diameter. I usually do that
by plugging in the number of teeth (count, count, count and count again)
and OD where it says pitch circle diameter, then selecting a standard
diametrical pitch or mod and recalculating the pitch circle diameter.
Depending on the tool you use, you can then print at full scale and place
your gear on top of the print out. Any errors will show up.
Milling:
My handy drawing program says for a 60T 2" gear, the maximum endmill is
.050", I run .031" EMs in my mill all the time. It depends on how thick
that gear is as to whether that tiny EM can cut it from flat stock,
though. More than about 1/4" and it'll just be too big. (I might be
able to carefully flip the gear over and get 1/2", but it's hard to get
that exactly exact.
I'd be willing to give it a try, it'll be nice to see a usable gear come
out of the machine. I often work on models with .3 mod gears and the
teeth are just too fine to cut with an end mill. (If you just look at
those tiny mills wrong, they break.)

I know you are kidding... But the Western Electric soldering iron

Your mention of the soldering iron reminded me that I still have Grandpa's

My oldest is the Craftsman radial arm saw. I had a Milwaukee 3/8 inch
corded drill that I gave away to somebody who was doing some major
home renovations, and a Bosch jigsaw that died the death (It's
repairable but the part isn't in stock closer than England and I
couldn't figure out a process for ordering it).

Some Illinoisians feel the same way about splitting of from Cook

I sold my old 8 inch Beaver table saw about 5 years ago - it was
mid-fifties. My 4 inch jointer was the same age, roughly. Sold it too.

Yep, it's 65 years old. My wife and I have been carting it with us
every time we've moved over the last 40ish years. It's about 4'
across now. They don't like extreme heat or cold so it gets moved in
the car with us (fun). It gets fertilized twice or three times a year
and then watered every couple of weeks and when it looks like it needs
it (more in the Winter).

How about pressing out the existing shaft and replacing with a new
one??

I've got a 1958 8 inch Skill Worm Drive saw - replaced the power cord
on it last summer.
I also have a Stanley J4A power door planer from about 1954 - in
perfect original operating condition.

Oldest still in active use would be B&D 1/2" drill in press that had
been around quite a while when I was a pup...I'd guess it dates from
mid-50s; certainly had been in the shop for a number of years by time I
finished HS in '63; I don't remember ever _not_ having it.
There are several others of roughly same vintage in hand drills, saws,
etc. The small B&D saw is one of "go to's". All that's been done to
any of 'em replace power cords and a couple of bearings that I know of.
As long as internals don't fail as in wearing out or breaking gears,
etc., what's to do?
Oh, I did replace the power switch on the saw a few years ago...a
close-enough match to fit was in the selection at the local Ace; of
course there are no actual parts available.
The latter bugs me immensely as I have at least three 3x24 belt sanders
(B&D 7440 iirc) that have the motor mounted _between_ the wheels so the
balance is better than anything on the market today. Unfortunately, the
drive gear matching the end of the rotor wears out and there are no
replacements available any longer (nor have been for 20+ yr now) and
haven't been able to find anything on open source that fits. Having one
machined was excessively expensive altho that raises the recent question
of what might be done with new 3D printer technology? Maybe I'll take
one in to the local community college machining class and see what they
can do...

It's been too long to recall exactly otomh so I'll have to dig one out
to be precise, but roughly 2"OD, probably 60-tooth or so...that's
probably a little high; more like in 40-ish neighborhood probably.

Thanks...I intended to go get the pieces-parts out of the drawer
yesterday while was nice out but got side-tracked on "must-do's" and
didn't get that far. I'll try to follow up although as I begin to
recollect, it seems that now I'm recalling it is actually the worm
gearing cut on the end of the rotor shaft or the matching gear to it
that drives the larger that is the set of matching teeth that give out.
The tiny diameter (3/8"???) worm drives the primary drive gear; it's a
two-gears-in-one arrangement where the inside matches the worm and the
outer drives the rest of the gear chain so it's not just a single flat gear.
As said, I need to go get pieces and make pitchures...I don't believe I
ever found a parts drawing online to point at.

That's good there's no rush since it's probably been nearly 15 years
since I've had one functional. :)
I did buy one off eBay a few years ago that is still functional but it
has some motor "issues" -- it runs, but not well and I've not taken the
time to delve into it much.
There's one w/ the cover off been sitting on a bench for years in one of
the garages--I glanced at it today and it is indeed the rotor end that's
the most worn of all; does look like it's straight gear but it's milled
directly in the rotor shaft; not tied onto the end. Not sure if doing
anything with that would be feasible unless could fill in the missing
metal and recut...
That one was never finished tear-down; still grease-covered (with a lot
of accumulated dirt/sawdust since :) ) so I'll have to clean it up or
get one of the other sets of parts to make pictures of and take some
measurements.
I have a Makita that is about closest there is on market to match but
they took a 4" machine and just put 3" rollers on it so it's too wide
for the belt and unbalanced left-right because weight isn't centered
over the belt. The little 3-wheeler looks kinda' cute and might be
nice, but they're just 3x21 so all the 24" belt stock is useless...
I've requested numerous times B&D bring the 7440 back with a little
better gearing, but never got anywhere obviously.

Indeed; it would be teeny to cut all the teeth down but to make
concentric and round wouldn't be too hard. Oh, but then there would be
very little room left between new ID and existing OD to match existing
size to match up with the driven...but, I suppose, still at least in

I'd guess that not possible from the rotor that I suspect the windings
and all are such that wouldn't be able to get the shaft out without
destroying it...but, I can look at how it's assembled.

'membered model number off by a digit -- it's 7450 instead 7440.
Here's bestest schematic found...gives an idea how it's built; the rotor
19 and gears 16,18 are the weak links; 5 and 10 never show any
significant wear at all...

I don't know. Maybe an old Skill jig saw I picked up as a toss in to
sweeten the deal on a grinder and drill press private purchase.
My tools have always been used hard. Most of the stuff I bought my
first few years as a contractor has been worn out and tossed. Sure I
could have fixed some of it, but it wasn't worth the time. Even the
good stuff. My time was more valuable getting jobs done for customers.
Now I'd fix it because I spend a lot of time watching CNC mills and
routers do my job for me. Nah, not really. If I am not programming, I
am designing. If I am not designing I am fixing a machine. If I'm not
fixing a machine I'm doing some off the machines fabrication or doing
some manual machining.
Now, when it comes to hand tools and machinist tools I have some old
stuff. I've got a few precision measuring instruments and misc tools
that might date back to the late 1800s. Certainly WW1 era. Some of them
I still use. No bull.

I'd say late seventies - it's made in Taiwan. Generally post vietnam
war era would be a pretty safe bet.

Some times, you get to bite the bullet, and replace with a newer
one.
I've a 3/8 variable speed craftsman drill. It still gets hauled
out for the occasional task, but mostly I'm using the cordless.

No rush, and now that I think of it they might have used helical gears.
I can cut a spur gear without much trouble, but helical is another story.
I'm not going to be able to cut a helical gear with my current set up.
I wonder if I could cut a form into a piece of O1, then use that like a
milling cutter with a rotary table to make the helical gear?
Obviously I can't promise anything, especially if they're helical gears.

A mini archive of some of rec.woodworking's best and worst!
Good one Leon -
My dad also worked for Western Electric and Bell Labs. He started in
the 20's in a vacuum tube plant in Chicago. I have his Iron some hand
tools and tool pouch. He retired long after 50 years and Bell Labs held
retirement up while he completed his 250,000 page manual. Research
Design and Director of Western. He retired out of one of his babies -
Concrete North Dakota. Big Radar. It is still working. Sisters to
this, solid state for the most part are in Hawaii and Alaska .....
They were designed to protect us from the North Korean missiles.
Electrical hum. I discarded my 1949 two wire metal case Drill motor
two years ago.
My surface grinders 50's and my Metal lathe 1952 are likely the best.
Metal lathe is a Sheldon L-44 Dad and I bought in the basement of a very
large Hardware store, Sacramento. We brought the War G case home with
us and box after box of tools and cutters. The box was new. And it sits
next to the Lathe. War grade means the beautiful Oak cabinet was
covered with Silk and then Painted Black. The box opens to oak faces.
[ I still have (last I looked) the bill of sale for the lathe ]

I'd guess that my Craftsman circular saw is about the vintage -- I've
relegated it to the dirty task of masonry cutting. I did have an even older
electric drill but it got dropped from a stepladder and bent the shaft and,
seeing no way to repair it, I junked it.

Wow! We'da killed the Christmas cactus long before now. LOL. I wife
gets one about every 4~5 years and it will last about 3 years. IIRC all
you have to do is water it. LOL

I have a 1905 Crescent 36" bandsaw... Electrical? It has a new Baldor 1
phase 5 hp motor--I sold off the 3 phase 5 hp that had new bearings
installed, cleaning and testing. The consumable things like bearings,
blades, and tires are readily available and all the cast iron is fine.
Beyond that I have a Porter Cable circular saw, drywall driver, and drill
that date from about '85 and a bunch of other PC tools that range from about
18-22 years old. With replacement parts available I fix them as needed... a
cord here, a base plate there. The random orbit sander has needed the most
work -- base plates/dust collection.
