Here are some details of making my Hand Plane Tap Hammer that you may find of interest. If you haven't seenPart I click here.
“Spoon Peening” a Brass Compression Ring
I wanted to dress up the intersection of the shaft to handle and decided to use a brass compression ring (see Red Arrow). The problem was that the compression ring inside diameter was 0.378”. This was okay where the ring actually butt against the handle but on the top side it had a little 0.023” gap. This meant I had a slight draft on the handle. I didn’t want to try to sand the shaft diameter because the problem would worse. So I decided to “peen” the top edge of the compression ring.
When I was a kid we used to make rings out of coins by drilling holes and then peening around the edge with a spoon. I decided to try this on the top edge.
Unlike making a ring, the peening would be only towards the center in order to close the diameter to what I needed.
After peening carefully, the top edge was now 0.355” diameter and the bottom edge was at 0.378” inside diameter. A complete success!
Tapping the PEX Brass Tee (The Head)
Next, I wanted to make replaceable head ends. I decided to make these out of 3/8”-16 hex bolts. First I tapped the inside of the Tee at both ends as shown:
Making the hammer head ends
I used two 3/8”-16 x ¾”L hex bolts. I chucked them into my drill and removed most of the flats on my bench grinder. It would have been better to do this with my hand grinder. Hand grinder discs are cheap next to wearing a bench grinder stone down and having to redress the flatness.
Then I finished up with a small file in my drill press. I touched up with some 600 and 1200 grit wet/dry sandpaper.
On the tops of the bolts I smoothly filed off the raised nomenclature.
It’s starting to really look good now !
Brass Plating the Hammer Ends
Next I brass plated the steel hammer ends and reassembled.
Next I spent some time polishing up the brass tee with some Autosol. I love this stuff!
Finally, I shellacked the torrefied maple shaft and handle. Then a once over with some wood butter.
Here’s the final beauty!!
Thanks for Looking!
