Plane Hammer This will be a hammer meant to be used by gravity as a Tippy Tapper in the shop vernacular. Since it has a hexagonal head, I have dubbed this model the TT6.
|
|
I had some hexagonal brass stock, an old Reese's piece...decided to cut off a run and make a plane hammer. Used a hack saw to rough cut. |
|
This head is three inches long...7/8 inches thick...end profile. |
 |
The head is about the same weight as a brass hammer that I currently used but the configuration will be much different. It will be thinner and longer... I considering a "dome" on one end with the other remaining square. |
 |
I cleaned up the six sides on the DMT lapping plate. |
|
Squared up the ends a bit... |
 |
One end had some machine markings... |
 |
The DMT lapping plate ate them up... |
 |
Placed the brass head in vise. Clamped the vise to the drill press table. |
 |
Drilled a reasonably appropriate hole. |
 |
Drilled a second hole...and then attempted a third...the bit went awry and really ate up the sides of the pretend oval hole. |
 |
Used the Bosch jig saw and a metal cutting blade and cut out the area between the two holes. The sides were very irregular. Had to work on them with files. |
 |
It took a good bit of work to get the oval hole in reasonable shape to receive the handle. The hexagonal shape does not clamp easily. I had to use alternative vise jaw faces. The drilling and surfacing of these holes really should be done on a metal working mill. |
 |
I found a piece of oak in the scrap bin. Worked it with shaves...cut a kerf...put in a shim...then blew out the end grain...set this aside...end of plane hammer 1...and later picked it up and created plane hammer 2 |
 |
So back to the hammer head... |
 |
Checking depth against the blown out piece... |
 |
My blank was plenty long, chopped off the split and using a tenon saw I kerfed the shoulder line all the around. |
 |
Chiseled down to the shoulder line... |
 |
Attacked it with Auriou rasps... |
 |
Workable fit... |
 |
Moved on to handle...will leave it long for testing. |
 |
Tapered the handle down to the shoulder so that it would be coplanar and smooth with the bottom facet... |
 |
Spokeshave edged and tapered the sides... |
 |
After a good fit, I cut a kerf with small tenon saw. |
 |
Test fit an oak wedge... |
 |
Mixed some epoxy and filled the eye... |
 |
Pounded in the wedge. |
 |
After cutting off the shim, I used Rotex 90 with 220x and softened all surfaces, oak and metal. |
 |
Doused all metal and wood with a heavy coat of Howard Feed N Wax.
|
 |
Rubbed in several coats of the wax...finishing with a drying of the conditioner with 320x. |
 |
Hand sanded all surfaces dry with 320x wet dry. |
 |
After finding the appropriate balance point I shortened the handle... |
