Subject: Blacksmithing/cross peen hammer

I've enrolled in a blacksmithing workshop and was told to purchase a 1 1/2
or 2 lb. cross peen hammer.  I am unfamiliar with this tool; any
suggestions as to where I could find one?

Thanks in advance!

HI Klass :) I work at a electrofused and deadburn Magnesia plant, In our 
electrofused operation we use the same principle as the one you describe 
but on a larger scale to melt Mgo into large 20ton ingots. The skin of 
the mantle is water cooled, but there is a 300mm bed of Mgo that is not 
fused which acts as a cup for the molten magnesia. Implying this to your 
process one cold suggest that  you immerse your crucible in a water tub 
and provide enough area so as to obtain an interface of powdered iron to 
molten iron.(maybe)
I am interested in the wiring configuration of your device, would it be 
possible for you to Email me the welder configuration and rough lay out 
of the set up. I have been asked by one of our process people to set up 
a similar model to the one you refer to.
Thanks in advance.

Well, Sears used to carry them a couple of years ago.

These are also known as 'engineers hammers' and they are the hammer in the
hammer and sickle on the old Soviet flag.

BTW: Go for the 1.5 lb model. It's got enough heft and won't tire you out
when you're just starting.

   Sears sells a 2 1/2 lb cross pirn hammer in thier hardware
department.
   
   A crosspeen hammer has a standard engineer or sledge pattern hammer
on one face.  The other face ( where the ball is on a ball peen
hammer)  has a wedge shaped face that runs crosswise to the handle.

   BTW the best hammer I have ever used is a Nevada pattern 2 1/2 lb
hammer.  It has two long tapered faces.  It looks somewhat like a
railroad spike hammer but the faces are not as long.  I think it was
originally developed for driving drill steels in mines, such as
Nevadas silver mines.

I purchased two cross peen hammers at Sears.  At the blacksmithing
workshop, ask to look at their copy of the Centaur Forge Catalog. It 
tends to be on the expensive end of the scale, but they pretty much 
carry almost everything.  Also, check with your local flea-market 
folks specializing in old tools.  Cross peen hammers are fairly
common in the old tool piles at flea markets.

They may carry a fair amount but having placed a recent order 50% would
have been backorder had I not passed on it. I've been on the Jay sharp
backorder there for over a year (with reports of other places getting the
backorders filled).

I also ordered thier PB50VS blower last year.  BIG bucks by the time it
got here. Not a good design. The "speed control" is a dimer which is
terrible on an AC motor. It might have had 1/2 a chance if the motor were
a 1725rpm but they chose a 3400rpm motor. I'd sure like to talk to the guy
who decided that those bits should go together. I either blow trees over
at 100ft or get a WAaaaaaaaWAaaaaaaaWAaaaaaaaWAaaaaaaa sound out of the
motor. 

They don't listen sometimes when I ask ship postal (UPS brokerage fee is
$30) and other times they split the order into several boxes (for no
apparent reason) and I pay brokerage on each one.

I stumbled across a straight pein hammer (well used) some years ago.
The face is pretty much shot, but I've found I prefer the straight
pein over the cross pein when it comes to drawing out metal.  The
position I hold the metal seems more "natural" to me.  And one of
these days I'd like to find a nice little 1-1/2 lb engineers hammer.
A buddy of mine had one, and it was great for doing small delicate
work.
