[TheForge] Pwr hmr anvil

Robert,
I would have to warn others against this level of cooperation and level
headedness; it could lead to a high success rate, and we all know how
complicated that can make things.

Frosty,

Maybe you could go down the food chain and make friends with the guys they
will sell the RR axels to. Get them to buy them and resell to you for a
reasonable fee.  Most business will help you out if there is a profit in it,
wouldn't hurt to try.

I've started ordering my steel with a local fab shop. It helps them get
there weight up so they get free delivery.  I helps me because I only have a
14 mile round trip to pick it up instead of 100. The guy uses my lathe so
about half the time if he's coming my way he drops it off.

We're in agreement Walt.

If I could get the 8 7/8" dia. RR axels I could put
together 2,000lbs worth of anvil easily. They'd only
need a few stitch beads to assure the billet couldn't
shift. They certainly wouldn't need to be welded solid.
This was exactly what I originally intended to do.

I don't have them available though and welding on a
pile of indiscriminately shaped scrap till it weighs a
ton not only won't look good it won't work.

If I can get them, (nothing's impossible) four, 30"
lengths will weigh around 2,076lbs. welded to a heavy
base and cap a "close to even" load would be okay. I'm
only talking about a 100 lb+ tup and RR axels are med C
or even 4140 in some cases, so close to even wouldn't
deflect one enough to cause a shear failure in my
lifetime, if ever.

Seven lengths welded in a hexagonal bundle, weighs in
at around 3,637lbs. not counting caps, base, etc. It'd
be about perfect for a 300 lb hammer. Dave Mudge built
a hammer this way after quite a bit of research into
built up anvils.

If on the other hand we're trying to get 2,000lbs from
say RR rail the end loading would indeed hit ONE rail
harder than all the others every single blow, even
through say 2" of cap plate and a die. 1080 steel under
those conditions will fail far sooner than I want to
repair it.

This is exactly why I was so bummed to discover the
recycling center would no longer sell to the public,
all I need is four, 30" lengths of the 8 7/8" RR axel
to make my weight. It'd be SO easy.

Frosty
