PH anvil thoughts

Recommended Posts

Made a trip to the steel yard, and was offered the friend price if I bought from the scrap pile outside.  Drew this up....

8AAF762B-49E3-4A4D-90F3-EE11EEDC692A-1.j

I'm thinking 12" timbers underneath.  The 2" layer is a 2 by 24 round piece of mild.  The 14 by 7 is round, and the top 6.5 is round.  Total weight minus timbers is the numbers on the right, roughly 650.

Will this be better, worse, or equal to a similar weight of round stock?

Joints, yes.  Haven't decided on bolt together with brackets vs. welding it around the perimeters.  Moveability later is a consideration, as I don't intend to stay in this house forever.

I'm thinking possibly weld the 6.5 to the 14.5, and triangular gussets?  Then bolt the rest?  Heck, IDK, lol.

Ok Solid mass trumps pieced mass; OTOH it's handy being able to mount a round on it's side to use it for drawing. Also as you get LARGE the change in efficiency gets fairly low.

That’s what I’m hoping, that the sheer mass will overcome the challenges of the joints. Thinking 50 to 60 lb tup, haven’t got that far yet.

Sorry, I missed the PH: for a powerhammer I would go monolithic as they get more "bounce" between the pieces.  I have seen PH anvils that use vertically arrayed sections welded , the Iron Kiss did it that way. The idea being that you have 1 interface between the die and the stand and another between the stand and the floor, rather than a bunch of interfaces from horizontally stacked pieces.

Well that all just changed, lol.  I went back out there and found even better options.  I think I'll end up with a 12 by 12 round with a 7.5 by 22 on top.  May put it on one of those 2" plates also.  655 in two pieces without the plate :)

He's giving me a good price.  I'm going to buy everything suitable for PH anvils and flip some of it.  If you can "flip" a 300 pound thingamabob.

Has a 6.5 by 48", 451 lbs. and a whole lot more.

I've done it; friend got a real good deal on some solid round, over 5" diameter, heavy enough to make treadle hammer anvils, medium carbon steel. I bought 4 and sold 2 for what I paid for 4 and gave one to another friend.

Yep, that's my plan.  Should be able to sell at 40 cents a pound, where the spot rate at the yard is 65, and I'll be making enough to pay for mine.

Yup and I have been out here 16+ years.  As soon as I get power to my shop and can use the Arc Welder; building that treadle hammer is high on my list!  I have   a 1" thick plate suitable for the base and some I beam for the back---though I recently saw some nice heavy sq tubing at the scrapyard.  I may redesign as I go along. 

Are y'all working up at Scott Forge?  We had been talking about going to Quad-State this year; but it's probably on hold till 2021. (TGLW&TCDR!)

Like most of my projects; they go slowly as I accumulate the needed pieces on the cheap and then: WHOOMP get done.  I'm pushing for more whoomps as I'm getting older.

Aren't WHOOMPS a source of TBIs? Don't be jinxing yourself I'm hopping to hook up at Quad-State in 21.

Lol, I hope I get a whoomp and not a TBI on this project.  So far I've got plenty of anvil material, a 30" circle of 1.75 plate at 350 lbs for a base, and I've purchased a tire and hub assembly.  Have to keep selling knives before I can whoomp.
