Store bought hammer mods

I made a flatter a while back from a section of car axle upset and flattened in the portable hole. Came out horribly misshapen and asymmetrical, but the one time I've used it, it worked very well.

In retrospect, I wish I'd put the time and effort into making a proper cold-cut hardy. I would have gotten a whole lot more use out of it.

Did some grinding on my 3 pound hammer and got one flat and the other head round. It is mad how careful you got to be to get out all the tiny kinks. Anyways here is my hammer.

I hadn't seen this post before, but have just finished doing the same thing as you folks.  I picked up a 3# Harbor Freight hammer, and with a couple of cutoff discs and a flap wheel, got myself a pretty reasonable double peen hammer for a little less than ten bucks.  It's not a Bailey hammer, but for the time being, it's quite good enough for me.  I found thinning the handle also made a difference in the grip, and the accuracy of my hammering; something about indexing in the hand, I suppose.

I am thinking of doing this again, but with a 2# hammer, to get something a little lighter.  This is a bit over 2.5# now, I believe.

Nice job. 

I thought about making mine into a double diagonal peen (as I'd like one of those), but realized for the grinding effort I might as well forge one out of better quality steel instead.  Of course I have to get off my butt and do that now...:unsure:

Latticino; the most interesting hammer mod I've seen in person was taking an old hand sledge with an octagonal cross section (not a regular octagon of course) and heating it in a propane forge and then using a hydraulic press to make it a double 45 deg cross peen with reversed peen directions.  Took about 2 bites each side with the press which left a nice curved peen face as well. Minimal clean up needed and the octagonal cross section made it easy to index the press dies to get a 45 deg peen orientation.

hydraulic press

Thomas,

Yes that is definitely the way to do it.  A hydraulic press is on my wish list.  Almost picked one up a couple of weeks ago (15 ton forging press, a steal for around $2,000 and even relatively local), but was a bit doubtful about the guides after finding out that it was a modified unit that was originally for flattening cans or the like.  If I hadn't had a massive headache that morning I would have driven the 4 hrs round trip to inspect it anyway.  Needless to say it went to the next interested party for even more than I had negotiated for.  So it goes...

The reason I saw it was it was after an ABANA affiliate meeting and the person modifying his hammer asked the smith if he could use his forge/press.  (You don't necessarily need the tools if you have *friends* with them!)

Steve, they're that sharp only because I haven't learned my lesson and eased them off with a flap wheel.  I'm sure that in the near future I will do just that.  So far, on smaller stock, it's working OK.  I can see how working something wider than the hammer face would look terrible in very short oder.

It also matters when you are working with the edge of the face and not the flat.  Hammering has a lot of techniques folks use; some more or different than others.

Chopped down the face of a little ball peen to make it a little more balanced. I’ve never liked how unbalanced ball peen hammers are. Planning on using this hammer for peening small rivets.

Size is so subjective: here's my littlest unmodified commercially made hammer---the one my wife uses to crack nuts at the kitchen table. That's a US penny coveing up the Champion stamp, (I have a champion forge and triphammers too...)
