Default Po' Boy Tech. How to make body hammers from scratch.

WARNING: You are responsible for your own safety. This thread shows you how I do things but that is not a guarantee that it is the safest way. Follow proper safety precautions.

Here's what you need to build a body hammer.

Chunk of leaf spring
1/2 inch dia. steel rod
angle grinder
flap disk, resinfiber pad, cutting disk, grinding stone wheels for angle grinder.
several inch section of 1/2 inch dia. Black pipe.
sanding block/paper
12 inch ball peen hammer handle $3ish.
Ultra fine point sharpie

Step One:

Select a farely low crown (flat) section of leaf spring. Give it a quick pass with the grinder to remove the rust so you can see to mark a line.


By onecoolkoala at 2012-08-31

Step Two.

Determine face size. Most body hammers have approx an 1 1/2" face. I selected a bottle with a base slightly larger than that to allow for mistakes. I can always make it smaller. Place the bottle you select on the spring and trace around the base with the sharpie.


By onecoolkoala at 2012-08-31
By onecoolkoala at 2012-08-31

Step Three.

Cut out the circle with the cutting disk on the grinder cutting several straight lines to create a stop sign type shape, then smooth the remaining corners with the grinder.

Step Four.

To make the main body of the hammer we need to cut three 1 1/8 sections of 1/2 inch dia. black pipe.

By onecoolkoala at 2012-08-31
By onecoolkoala at 2012-08-31

Now place one of the sections in the vise with the seam facing the vice jaw as shown.

By onecoolkoala at 2012-08-31
Slowly tighten the vise just enough to make the pipe oval shaped instead of dead round. This makes it harder for the handle to spin inside the head.

Take the second and third sections of black pipe and cut a 1/4 inch wide piece out of the side as shown.

By onecoolkoala at 2012-08-31

Now place the pipe over the edge of the vise and hammer it gently till it spreads enough to surround the first piece of pipe.

By onecoolkoala at 2012-08-31
By onecoolkoala at 2012-08-31
By onecoolkoala at 2012-08-31
Trim the to pieces to fit tightly around the center pipe.

By onecoolkoala at 2012-08-31

Now use a zip tie to hold the pieces in place while you tack it all together. After a couple of tacks the zip tie melts so put one tack on each piece right away.

By onecoolkoala at 2012-08-31
By onecoolkoala at 2012-08-31
By onecoolkoala at 2012-08-31
Tacked up.
By onecoolkoala at 2012-08-31
Fully weld all seams. The piece should look like this.

By onecoolkoala at 2012-08-31
By onecoolkoala at 2012-08-31
By onecoolkoala at 2012-08-31
By onecoolkoala at 2012-08-31
Grind all the welds you just made flat.

Step five.

Now we need to bevel the botton of the hammer head body so that it doesn't cut into the handle. To do this I took a die grinder with a stone in it and beveled the handle hole by hand, You don't have to get real crazy just try for a gentle, consistent radius.
By onecoolkoala at 2012-08-31
By onecoolkoala at 2012-08-31

Step six.

Now you need to make the stems for the face and cross peen portions of the hammer. For these pieces cut 2 sections of 1/2 inch solid rod about 2 inches long. You can make these stems longer or shorter depending on how you want your hammer shaped. The short piece of rod in the picture is going to be the cross peen itself.

Take one of the stems and stand it in the center, on the backside of the face of the hammer

By onecoolkoala at 2012-08-31
By onecoolkoala at 2012-08-31

I just eyeballed the stem on the backside of the face to find center. Just get it close, we'll perfect it later. Same thing to make sure the stem is square to the face (stem should be 90* to the plane of the backside of the face). Just eyeball it from four different sides to make sure. We will grind on the face of the hammer later so slight variances at this stage can be corrected then. This picture is after the assembly is welded and has been turned over but it shows what I am trying to describe.
By onecoolkoala at 2012-08-31

When the stem is where you want it clamp it in place.
By onecoolkoala at 2012-08-31
By onecoolkoala at 2012-08-31
By onecoolkoala at 2012-08-31

Tack and check that the stem hasn't pulled out of square/center, then finish welding it.
By onecoolkoala at 2012-08-31
By onecoolkoala at 2012-08-31

Now turn the assembly over and double check for square.
By onecoolkoala at 2012-08-31

As long as it is close to square your good. You can fix the inaccuracies later.

Step seven. Rear stem and cross peen.

Take the second stem you cut earlier and cut a trench into each end perpendicular to each other.

By onecoolkoala at 2012-08-31
By onecoolkoala at 2012-08-31


By onecoolkoala at 2012-09-06

Lay the short stem you cut in one of the trenches like so
By onecoolkoala at 2012-08-31

When the short stem is centered and squared on the long stem clamp it in place.
By onecoolkoala at 2012-08-31
By onecoolkoala at 2012-08-31

Tack and check that it didn't move, then finish weld it
By onecoolkoala at 2012-08-31

Step eight.

It's time to true up the face end now. Place your angle grinder in the vise (jaws clamping on the aluminum housing not just on the plastic!) and rolll the edge of the hammer face on the grinding disk to smooth the radius.
By onecoolkoala at 2012-08-31
By onecoolkoala at 2012-08-31

Radiusing the face.

Before you start, make sure the surface of the face is perpendicular to the stem. If there is a high spot/side dress it with the grinder until the surface is flat then begin the radiusing process.

First, mark center on the face with a marker. second, using the grinder, make concentric circles around the center mark grinding more on each circle the farther toward the edge you go. The red lines in the picture below illustrate the approximate travel pattern of the grinder.
By onecoolkoala at 2012-09-07

You don't need to remove alot of material. I personally go for a low crown. It isn't an exact science, just eyeball a low crown that looks good to you. Also, don't worry about getting the surface perfect right now. We'll clean it up with the sanding board.


Step nine.

The stems of your hammer faces should have trenches cut in them like so.


Step ten. Mock up

Here are your three parts together


Grind the welds on the face ends of the hammer. If you wait until you weld it all together you won't have room for the grinder. I used a flap disk for most of the grinding/blending.

By onecoolkoala at 2012-08-31
By onecoolkoala at 2012-08-31


Step Eleven.

Put the face end and the center body in the vise like so.


By onecoolkoala at 2012-09-06
By onecoolkoala at 2012-09-06


Before you weld these up you want to make sure the main body hole for the handle is perpendicular to the stem of the face and that the stem is not angling left or right away from the main body. Bottom line look like it does in the pictures before welding.

Welded up.

By onecoolkoala at 2012-09-06
By onecoolkoala at 2012-09-06

Now add the cross peen end the same way checking level and square as you go.



By onecoolkoala at 2012-09-06
By onecoolkoala at 2012-09-06

Both ends welded up.



Now grind the remaining welds.

Step twelve. Polishing up the faces.

I polish the faces with 220g on a sanding board/block, then 400g, then 600g, and finally white rouge on the buffing wheel.


By onecoolkoala at 2012-09-06
By onecoolkoala at 2012-09-06

I also polish the sides of the face like so.

By onecoolkoala at 2012-09-06

Don't forget the peen end too.


By onecoolkoala at 2012-09-06

Hit it on the buffing wheel...




Tada!


By onecoolkoala at 2012-09-06

Were not quite done. Use the grinder on the back side of the face to thin the face to about 3/16" as shown.


By onecoolkoala at 2012-09-06

Also, file any sharp edges so you don't cut yourself or your work well handling the hammer.

Now lets get some paint on this bad boy.

First tape out every thing you want to stay shiney (duh)

By onecoolkoala at 2012-09-06
By onecoolkoala at 2012-09-06
By onecoolkoala at 2012-09-06

Then prime it. I stuck it on an old handle while i painted it so that I didn't have to paint it in two sessions. Just put the old handle in the vise while it dries so the head doesn't have to rest on anything.


By onecoolkoala at 2012-09-06

Then paint it.
By onecoolkoala at 2012-09-06

When the paint is dry untape the faces and install the handle. The handle is a 12 inch ball peen hammer handle that you can get at any hardware store. Surprisingly similar to a martin hammer handle


By onecoolkoala at 2012-09-06

File handle to fit.


By onecoolkoala at 2012-09-06


Istall the head and wedges per handle instructions. Repolish faces to remove tape residue, and you ready to go bang some metal!

Here are a few pictures comparing the hammer we just made to an original plomb 1426 body hammer.
By onecoolkoala at 2012-09-06
By onecoolkoala at 2012-09-06
By onecoolkoala at 2012-09-06

Now somebody is gonna say "Why not just buy martin hammers? They are fairly reasonable?" Well, some body hammer patterns have been discontinued and there are some custom designs of my own that I think will be useful. And the price of old body hammers is outrageous. We made this hammer for about $6 and an afternoon.

Well, I hope you like it. If you have any questions please ask. And of course, vote for me!!

America is making tools again



I think the concept is great. Someday someone might say; "my gramps made this hammer".

Some might not get it.

I've been wanting to modify a long curved pick I never use. I think I will, after seeing this.

I think this is great! You can make them specialized to what you need, and you can take pride in doing it yourself. Guys who do a lot of bumping know what it means to have a good quality hammer that has the right anvil on it.

Thats true!
You can also walk into a Hyundai dealership and buy a cheap, reliable car WITH a warranty.
WHY build one????

Because you can.

(BTW...don't confuse HF or PA cast junk as "body hammers & dollys". NOT the same thing at all.)

The crap the chinese make and sell over here arent worth the 15-20 bucks they sell for!! I've made many a dolly and slap hammer in my day, but never a hammer. Maybe that's just cause I have used the same 3-4 hammers for the last 15 or so years. But, that is one thing I have never thought of making myself. A good forged hammer is just not that pricey that I won't buy the one I need. But, Good job man! Home made tools is where it's at!!
