[TheForge] A&O

Wed May 7 13:45:01 2003

Mike,
Sounds like you have your hands full with hammer projects!~
The innards sound an awful lot like a Nazel. Do you have a Manzel or other brand of automatic oiler on it or drip oiler? The Nazel's con-rod has a similar cup attached to the shaft that runs down to the crank pin. Being a passive system, I usually prime it first by removing the cover plate and force feed it a few squirts. The rear crank bushing (bearing) is also drip. Everything else; ram cylinder, compressor piston and main bushing are all pressure oiled from the Manzel, parts of which are still available new. The wrist pin is the only thing that relies on lubrication by osmosis. Oil has to find it's way into that area after sloshing around in the piston for who knows how long. 
I've gotten to be pretty acquainted with my hammer after going the extra mile to get things as close to factory as possible. One of the latest projects was getting the ram line-bored which taxed heavily the mill assigned for the job. Most diesel shops are set up for boring cylinders which are no-where near as long as a 3B ram. I think the total length they bored out and sleeved was close to 20". Overall, they did a fine job and it brought back an amazing amount of performance. 
Guide plates; bronze is probably fine since you already have it. Mine are worn C.I. but in manageable shape. I looked into making new ones of cast iron which rough sizes can be bought from MSC or grainger. On a 3b they are 4X12" which makes it convienent. The real cost would have been machining the dovetail into the guides to hold the leather rings. I'm assuming the A&O has a similar set-up.

Let us know how it goes,

No patent number found so far.  The maker's name is cast into the
body.  There's a brass plaque attached by the Montreal importer.  I'll
look again but I don't think the patent number is there.

Other Alldays & Onions news:

I've got staging built around it and a 16' bipod rigged over it.  The
tup is out and all cleaned up.  Today I got the cover off the
compressor -- weighs almost as much as the tup, a 24" manhole cover.
Yesterday I got the valve sleeve out and cleaned it up tonight.

I think I can clean the tup bore with Scotchbrite pads on my angle
grinder, same as I did the valve sleeve.  Several patches of rust
pitting but no really bad spots.  The inside of the compressor looks
real good.  I may not have to take the piston out.  Everywhere else
there are pockets and layers of rusty oil, grease, water and slime but
just some dried-up grease in the compressor bore.

There's what looks like a grease cup on the compressor conrod and it's
full of grease but I think it's meant to be an oil reservoir.  Gotta
figure that out.  It has a little brass standpipe in the center.  I
think it's supposed to be filled with oil and the motion of the conrod
is supposed to slosh oil into the standpipe a little at a time.

Found some bearing bronze for the tup guide/alignment plate but it may
be too thick.  (I asked for gunmetal -- what the specs call for -- but
they told me that you can't get that stuff no more.)  There's another
smith nearby that I believe has a machine that will plane it down a
bit.  Other repair parts for the guide bar -- new bolts, 1/2" helicoil
-- are in hand.

No luck so far on a replacement Webster mag for the gas engine to run
this beast but a possible deal if my '47 International pickup carcase
is good enough for a swap and a possible free Dodge truck engine
that's been in sombody's cellar since it was factory-rebuilt.

All very exciting.  Trying to make significant progress before I get
distracted by gardening.

- Mike
