This is a true Barn Find story. While restoring the 1929 Model A pickup truck I was asked by the owner to go and look at a few body parts for his restoration project at a property in Candia, NH. While scouting the property of old classic and vintage cars, which included a couple of 1940's Cadillacs and 1930'sLaSalle along with a few 1950's Metropolitans and several Model A Fords, I discovered my 1938 BMW 327 Cabriolet sitting in a shed. My greatest weakness is for orphaned cars left behind because nobody in their right mind would ever conceive of bringing them back to life and this prewar BMW was no exception. I inquired about the car and found that it was owned by another person who lived in MA and so the acquisition was afoot. I immediately contacted the owner and negotiated a very reasonable price. Now this type of restoration was way beyond anything I had ever attempted in the past. It was clearly evident once I began disassembling the car that there were lots of parts that were missing, deteriorated or broken that all needed to be replaced. The greatest hurdle was the body since replacement parts are not available. Being self-taught for most of the skills I have, I knew that if I persisted I could make all of the components that are not available. I began collecting as much literature and information on sheet metal fabrication, shaping and forming to be able to manipulate flat sheets of 19-gauge steel into complex compound curves. Once I had acquired the basic knowledge I bought an English Wheeling machine, a Pullmax P-3, a shrinker & stretcher, a Ram planishing hammer and built a Power hammer. I also already had a fairly extensive set of Pexto body hammer & dollies. I originally thought that it would be somewhat easy to master, but I was wrong, I generated a lot of scrap before getting the parts exactly the way they were supposed to be. Being a perfectionist has its benefits as well as its drawbacks.
The body on all pre-war BMW's are supported by an internal structural wooden frame being made of either ash or maple. Due to the extent of body deterioration, moisture rotted away much of this wood, but left enough that I could use the individual pieces as patterns. Some of the pieces are very complicated and detailed with compound shapes which necessitated the need to build a 3-D router carver. Even with the aid of the carver, it takes about 2-weeks to make all of the wooden pieces. I have made complete sets of structural wood for six pre-war BMW's of which most have been shipped to Europe.
I also needed to make cast aluminum and rubber parts, also skills that I never had before. I taught myself how to make patterns and built a furnace and copes & drags to cast aluminum parts using Petrobond oil-based sand. Rubber parts like the weather shields/boots for the rear springs, bumper bracket cushions, pluming line cushions and emergency brake bellows all need to be made. Silicon rubber molds were cast from patterns I made based on deteriorated original parts. Silicon rubber was also used to make the mold to reproduce the cast in-place white windshield opening knobs. Luckily I had a good original knob to use as a pattern for the mold.
