It all starts with a thorough cleaning of the parts to be coated, which may involve sandblasting with a medium-abrasive media. In the case of the suspension parts, Dudeck 'pre-brakes' the control arms, at a pizza-savvy temperature of 400 degrees Fahrenheit. This process sweats out any oil or grease, which could cause problems with the coating adhering correctly. Dudeck hangs the parts to be coated on a special rack, which has an electrical ground. The grounding causes the parts to attract the powder, which is sprayed wiht a special electrostatic gun. Dudeck uses a selection of spray hoses for the powders, which can't be mixed up. That is, unless you want a two-colour speckled effect. The charged particles find their way deep into the V-grooves of the recently-sandblasted control arms.
Once the arms have been coated, the oven is fired up. "It's basically a big convection oven," said Dudeck. Temperatures can range from 250 to 400 degrees, depending on the materials being coated. This is where the powder coating transforms into a durable finish. In the early days of the technology, many newcomers did not understand the importance of maintaining the metal at a certain temperature. "The metal actually expands," said Dudeck. The expansion process enlarges the size of the V-grooves, allowing more of the powder into a gel-like consistency. Once the proper amount of heating time has elapsed, the cross-link of the resins is complete, throughout the surface of the control arms. Dudeck's product line includes over 100 colours, with the ability to create any type of automotive paint finish.
That powerful powder is joined this week by the source of electrical power for our Chevy. Dixon Barroe, a Via Rail plumber, contacted the Wheels of Dreams Parts Hotline via email, with 850 cold-cranking amps of 12-volt goodness for our Chevy. The brand-new top-post Motomaster Eliminator battery will provide plenty of starting power. "I read the coverage all the time," said Barrow. "It sounds like a really good project." The extra battery came into Barrow's hands, after finding a warranty card for a battery he recently replaced. "I probably could have sold it, but I figured it would be better to use for a project like this," said Barrow. He's been impressed with the outpouring of parts and services for the Wheels of Dreams project. "As far as I'm concerned, Winnipeg is one of the best car places going," said Barrow. "Everybody you talk to has an old car, or is fixing one up." The good news is that the generosity of partners such as Dudeck and Barrow shows no sign of stopping. There are numerous donations on tap, which we'll be telling you about the in the coming weeks. There are still a few bits and pieces needed. One of the latest items to hit the street rod scene is LED taillights, sized specifically for the 1940 Chevy. Feeling generous? Email Michael Clark today.
