[TheForge] Pwr hmr anvil

I can't believe that it is important to join your axels vertically.  Mostly what you want with an anvil is mass and you want to engage that mass.  With a thick enough top & bottom plate, all of the axels should load up close to being uniform so your only concern is what we call slenderness ratio with building columns.  You don't want the individual columns to buckle under load.  I doubt they would ever do that but if you were concerned, you could collar the bundle of axels at a couple of points.

You're correct to a point Ron.

In reality there is a limit to how many pieces and or 
shapes you can weld together and end up with a mass 
that is competent for an anvil. The RR axels I was 
hoping to buy for scrap prices were very useable. Cut 
to the correct length and welded to a thick base the 
longitudinal welds joining the axels would've suffered 
very little shear under the hammer.

I considered using RR track as there's a largish pile 
in the back yard at work nobody'd mind disappearing. 
The problem is welding up 1,500-2,000 lbs of it into a 
smallish package without causing severe heat stress, 
imbrittlement, shear zones and a whole raft of 
potential failure points.

I know most of you don't know how far we are from a 
real industrial community in Alaska but a piece of 2" 
plate is a special order. 6" sq. bar is likewise a 
special order. If I could find either for scrap to 
reasonable prices I wouldn't have any heartburn about 
welding up an anvil but you just don't see this stuff 
around here. Not often anyway. Still, rare as it is 
here abouts I keep my eyes open and have the word out.

Heck, a counter weight off a decent sized forklift 
could be adapted. I'm flexible. <grin>

Frosty, you can weld plates, rods bars, rr track, etc 
together for an anvol;
the steel doesn't care
