TM Reverse Air Hammer Dies
|
|
|
When you need to make a "saddle" shape, a "ducktail" shape, or a "fairing" shape you need these dies. These shapes are called "reverse" shapes and because they are the reverse of a bowl or hollow shape they will not hold water. Reverse shapes can be difficult to master, as well as to make properly. The hand method requires that you use a round-faced mallet and a shot bag or a sand bag to whack away at the metal until is is roughed into sort of what you need, and then you have to smooth it out, either with a slapper and dolly or with a Wheel.
Folks that use these dies say they are much faster and you get a better job. I had a race with a guy one time, and I let him have an hour's head start. I finished first, and my part had a better appearance. He left the shop without saying anything.
If you are careful with these dies you don't have to do much smoothing. Your hammer does have to be set up carefully so the faces of these dies line up right on the button. We have two sizes, one for large reverse shapes and one for small reverse shapes. The dies are hardened steel and they are precision ground. Made in America.

Large Reverse Die Set
This hardened steel die set has precision
ground faces. For stretching the metal rapidly and accurately and
leaving minimal marks. For making large reverse and saddle shapes such
as ducktails and aircraft fairings these dies stretch the edge of the
metal. Also known as linear-stretching dies. Kent once had a race
with a man who was using a mallet and a bag to make some aircraft
fairings. The mallet and bag man made his fairing in 2-1/2 hours. Kent
made his fairing using his air hammer and the Large Reverse dies in 35
minutes. These can be used to shape any metal. They cannot shape metal
over 3/16 thick. Please note: The bottom die must be held stationary
by using a strip of adhesive tape to work correctly (see Air Hammer
Operations DVD for specifics).

Small Reverse Die Set
This hardened steel die set is precision ground
for perfectly flat working surfaces. It is designed for working in
tight places, and on parts with small radii. Designed for making small
fairings and saddle shapes rapidly with exceptional control and minimal
marks.
