Vince,
You are awful lucky...those scrap yards around here
that get stuff like that wont let you walk around.
Those that let you walk around only end up with the
occasional industrial surplus...
I'm in the process of building a 20 ton RAM style tile
press for friend. With new steel stock approaching
all time highs, I'll be frequenting scrap yards to
locate large pieces that I can make work.
I've viewed your website before. Back when I started
building my pugmill. Someday I'll finish that
project. In the mean time I have to do homework. I
made the mistake of deciding I was going to make it
out of stainless, I have all the materials, but dont
have a slip roll, so I can't form the tube. Haven't
yet found a piece of stainless tube at the scrapyard
6" in diameter. Probably will right after I machine
my slip roll :)
-Jacob

Most people looking for gear reducers overlook shaft-mounted gear reducers,
and they are some of the best ones for pugmills. They tend to be fairly
abundant in scrap yards, especially when there is lots of industry close by.
They are frequently used on conveyer systems used in many kinds of industry.
Other gear reducers mount on the machine frame, while this kind actually
mounts on the main shaft of the particular machine. The "bull gear" in the
shaft-mounted gear reducer has a bore going through its center that opens to
the outside on both sides of the reducer, and this mounts on a keyed main
shaft, in this case the auger shaft of the pugmill. The main shaft in turn
is mounted on two flange bearings on either side of the gearbox. At my
website (hyperlink below) go to "gallery" and then to "Railroad Stoneware,"
and in the lower left you will see a picture of my pugmill with the Falk
shaft-mounted gearbox. The image is a little dark, and you cannot see the
rear stantion and flange bearing that support the back end of the shaft on
the left side of the gearbox.
The input shaft emerges from the gearbox parallel to and behind the main
shaft, and I used a twin V-belt drive from the motor. A stay-arm mounts to
the pugmill frame, and the other end mounts to the gearbox with a slotted
bolt hole. To snug up the V-belts, you just loosen the stay rod, swing the
gearbox upwards, and tighten the bolt on the stay rod.
The image on the website might be deceptive. This gearbox weighs 160 lbs.,
and the bore for the main shaft is 1 15/16".
When I built the pugmill in 1979 that gearbox retailed for $1200, and I
bought mine in perfect condition at a scrap yard for $45, including a big
conveyor pulley with bearings that I converted to a (very heavy duty) lawn
roller. The gearbox is overkill for the pugmill, but the price was right
and it will never wear out. I have seen lots of these gearboxes in scrap
yards.
Best wishes -
- Vince

Consider also places as do 'recycleing'...
Private parties as have 'junk' laying around...
Places as repair/rebuild Electric Motors...as repair/rebuild
small Engines...
Older Manufacturing or Machinery related businesses as have
back yards or out-door room to let dis-used stuff sit
around...
Used Machinery dealers...
Ads in the newspaper for related things people are wishing
to get rid of or sell...
Old Men who wear 'overalls'...(you know, having a
slice-of-pie in a cafe or something, ask them...)
Anyone who wears 'overalls'...(ditto)
Anyone who wears 'coveralls'...(ditto)
Dirty overalls or coveralls are likely a 'plus'...
Places as sell 'Steel'...
Look carefully in older Commercial areas where various small
businesses have stuff lieing around outside...
Places as rebuild older Air Compressors, Hydraulic
Cylinders, Hoists, Boilers, whatever...talk with them, maybe
they know where caches of useful things are...
People as have lots of junky or derelict cars sitting
around...
On and on...
Like that.
Scrap Yards as such are seldom so well defined as to be in
the phone-book, and more often exist in smaller and less
obvious ways...
Like any Squirrel or Bird...to know one's 'Forrest'...and,
'where' different things (maybe transiently) are...or may
be, found...
