Some parts I made at Nelic Engineering |
Some parts I made at Thompson Machine |
Some parts I made at Power Industries |
Here is a description of some of the parts. At Nelic Engineering I made all of the tooling dies that stamped out these parts and other workers ran the production runs with these dies. At Thompson Machine most of the jobs were for a limited number of parts, so I made the tooling and ran the jobs too. At Power Industries most of the jobs were short production runs of machined parts where I did the machine set-up, made tools and fixturing, and ran the job.
The exterior shape and all of the features on this plate where made in a single hit from a single station die on a 180 ton capacity punch press. The plate is 1/8" thick aluminum, 8" wide, 12" long, and has 41 perforations. |
Manifold Cover made out of Sterling Silver. Formed in one hit from flat sheet stock and then the outer shape was trimmed to size in a separate die. |
High Temperature Rocket Nozzle Cover made from nickel. Three station progressive die with carbide tooling components. |
The row of copper pieces shows the progression of steps (draw dies) it took to make the final part shown at the right. The final part is made out of tantalum which is a very expensive material and copper was used to test out the dies before the production run. One hundred parts were required. The wall thickness had a close tolerance of + or - .0003". The flat stock material was already at the finished thickness, and therefore many reduction dies were required to keep from thinning the material out of tolerance. |
Stainless steel High Explosives Container for Sandia National Laboratory. A bolt was soldered in the hole in the can. High explosives were loaded in the can and then the lid was sealed to the can by crimping the rolled edge of the lid with a tool I provided. The lid has four very narrow .007" wide slits to direct the explosion in that direction. The limits of normal die making were pushed in two ways on this job: first the can was made in one draw which is extreme for the can's depth and small corner radius and second the width of the slits was less than the material thickness which makes the piercing punch very weak and a challenge to make (and run without breaking). |
Earrings made out of titanium. Titanium turns to many colors of the spectrum when it is oxidized and the jewelers have ways of producing many interesting multicolored patterns (not shown here). |
Components for ultralight aircraft. Clockwise from bottom left: Propeller Hub, Folding Wing Joint, Wing Flap Control Lever, and in the center a Cable Quick Connect. I Also made parts for the landing gear unit. |
