I wet sanded and buffed the Blower Bike’s tank today. I re-cleared it last week. It looks as good now as when I first did it in 2007.
I’ve used that wooden stand it’s sitting on to Bondo, block sand, and run a buffer on every one piece tank since 1980 when I put it together. That’s 46 years and a Hell of a lot of tanks. 😎

A little while back, a painter friend I know from my Brookville shop and C&W Body Shop days, Chad Wilson gave me a Trek bicycle for free. After turning down money, I offered to paint him with artwork on it.
Chad painted a little 12”x16” aluminum panel a bright metallic Lime Green and gave it to me to do something on. I did a drawing of a spider with Harley-Davidson lettering underneath it. I masked, cut and sprayed the initial spider’s body and lettering black then got too busy to finish it. A year went by.
One night a couple of weeks ago while watching an old episode of Star Trek (Mirror, Mirror from 1967) I saw a shield in the background of one of the scenes. I was immediately inspired.
I did a drawing, cut a piece of 1/16” thick aluminum sheet in the shape of a shield and painted it turquoise, trashed it up with a little fading and airbrush effects and threw some metal leaf lettering on it. After that I cleared the s**t out of it, wet blocked it flat, and polished it.
If you’re reading this Chad, you can come get it anytime. Maybe one of these days I’ll get around to finishing the Green one you brought me. 😎

Among the other projects I have in the works is this 1965 Rupp Go-Kart with a fiberglass body based on the 1965 Chevrolet Monza SS Show Car. These Karts were manufactured between 1960 and 1970 in Mansfield, Ohio.
The Karts and bodies were originally designed with kids in mind, but have become popular with adults, especially Shriners to be driven in parades.
Adults have a hard time fitting into them comfortably, so this project requires me to move the steering wheel forward three and a half inches and cut the body’s driver’s opening and re-glass it correspondingly. 😎

Wet sanded and buffed the rear fender of the Blower Bike and bolted it on only to find out the LED board in the taillight took a s**t. I had drilled holes through the back to enable me to push the lens out for this very reason.
I did this 20 years ago and thought there was just the center hole. Pushing too hard in the center resulted in breaking the lens. I was surprised to find out the lens is actually made from a piece fluorescent light fixture diffuser with the back side painted HOK Brandywine. It’s held in place by thin strips of windshield butyl.
Now to find a similar replacement board since this one is discontinued. 😎

I’ve been busy for the last two months getting the Gold Bike ready for the road again after sitting 4 years with a blown up engine and a scrapped Magnacharger.
I’ve had to repair and repaint areas of the frame, swingarm, and front end, as well as repair damage to both fenders requiring their reclearing and rubbing.
I’ve installed new chrome Platinum Air Suspension shocks to replace the leaky Tricky Air units and upgraded the electrical system to a Noco lithium-ion battery and had Josh Beasley polish the heads and cylinders of John Sally’s donor engine that took care of our Magnacharger search problem.
The engine’s lower end is in the frame and I’m just playing the waiting game for the custom made JE dished blower pistons and rechromed exhaust to show up. We’re planning on taking it to Sturgis in August.

While searching for the original video of me riding the Blower Bike my son Deven came across this short unused clip of me riding the black wide-tired Bad Boy.

In 2918 I asked my son Deven to take all the photos of the Blower Bike’s construction, combine them with a video of me riding it and compose some music to accompany it reminiscent of Queensrÿche’s Empire. After only 4 hours this is what he came up with.
Search Deven Jahnke on YouTube. You can see his posts going back 13 years. 😎

Once I had the fabrication and bodywork finished on the “Blower Bike” or “Gold Bike” I nicknamed it, and the frame, swingarm, and oil tank were painted House of Kolor Goldmine Pearl Shimrin basecoat with a tint coat of PPG DBC 500 clear slightly tinted with Metalflake brand Aztec Gold Candy Concentrate and cleared with 3 coats of Nason Select Clear.
I turned my focus on the pieces requiring artwork. I sprayed everything with grey Medallion 2K urethane primer, let it sit overnight, dry blocked it, and re-primed it with 2 coats.
The next step is to draw on the parts with an ordinary No.2 pencil what was to be masked off and painted Black basecoat. I took pictures and made templates using artist’s tracing paper with measurements for reference.
Once the Black basecoat designs were sprayed and Candy Tangerine shading added, I striped the edge of the Black with vermilion water-based Cel Vinyl followed by 5 coats of Nason Select Clear Urethane.
After letting it dry overnight, I wet sanded everything flat and re-cleared it with 2 more wet coats of the Nason clear to later be wet sanded with 1000 grit, 1200, 1500, finally 2000 before hand or machine buffing.
The Blue circle on the tank with the skeleton coming out of it is a combination of airbrushing and hand painting done with Cel Vinyl and Liquitex acrylic paints. 😎
