Go to GALLERY to see photos many new projects completed. I have been SO BUSY recently, that adding new images has not been top priority. Yet, take a look here and there to see what's new. Thanks!
As kids, my brothers and I were amazed to find that the Chinese had actually invented gunpowder, to our collective disappointment.. Our suburban neighborhood windows resounded with the pulses of shock waves, and more often were pierced by BB's, arrows, and other launched projectiles.
Naturally, the first instinct, and order of business when learning to operate a lathe was to turn out a cannon!.
Fortunately, these loud beginnings were tempered in time.. John is now a craftsman and general contractor at Ananda near Grass Valley, CA where his skills as an inventor makes him the "go-to" person for all that makes shelter more comfortable. and meet code.
Look closely at the gold lines in this cast iron piece. Click on the photo to enlarge it. These are the bronze allow brazed fusion lines that remain after machining the surfaces back to original dimensions. I used special cast iron brazing alloy from Muggy Weld .com in this repair. Click on photos below to see the various stages of repair. There was no need to replace the broken out original cast iron piece pictured below. Substituting it with a larger steel piece made more structural sense.
These Stainless Steel glove box tabs were stamped from dies made from steel and epoxy resin. The cost of these dies is reasonable compared to the cost of having steel dies cut from solid steel that would otherwise break a deal for such a short production run.
Photos below show that the more complex positive and negative shapes we CAST from the original sample part in high compression resistant iron filled epoxy resin. The material held up well enough to stamp several hundred more stainless steel shapes.
This valve functions the same as a radiator cap on Rolls Royce vehicles built in the late 50's and 60's.. Leave it to Rolls Royce to invent their own solution to to maintaining coolant pressure and venting excessive steam over a conventional radiator cap. These early units fit inside a remote reservoir tank, and are discontinued from Rolls Royce. This opened an opportunity to be remake these steam valves as a needed aftermarket replacement item.
We made all the metal stamping dies to recreate these valves, and went a few steps better. The inner valve is now a more positive proven design, and the valve body is made of pure copper.
The coil in the foreground is functional copy of the original 1937 Alfa Romero BOSCH coil (on the right). I have adapted the new coil to run using a magnetic electronic ignition hidden under the original breaker plate in the distributor.
We made the various components from available shapes and compatible materials as can be seen in the photos below- from concept to illustrations, to final part.. I tested the final unit on my 51 ford pickup truck that is running the same Pertronix ignition system before shipping the coil off to my customer.
