How to Paint an aluminum chassis at home – the Pastime Projects Way

August 3, 2016

I have an aluminum chassis with some scratches on the surface. The usual methods of preparing the surface include sanding, etching, several methods of cleaning and final preparation of the surface using caustic materials and/or
primers and so on.
I liked the old timer radio chassis look of the 1940’s and 1950’s with the crinkled black finish. I also like the
“Radio Kit” approach of the 1960’s where the look went to cool “crinkle finish” variations in green-blue
shades of color.
For preparation I washed the chassis with warm soap and water, then wiped it dry with a very soft “bar towel”.
I made cardboard cutouts the size of the vacuum tube flanges. I purchased some double-sided tape and covered one
side of the cardboard cutouts with this tape. After trim, I located these on the metal chassis. Most of the other holes on the chassis were covered with AVERY #6733 “Color Coding Labels”. I have seen these used for pricing things at garage sales.
Many stores carry the “Rust-Oleum” Brand of spray paints. I found Rust-Oleum “Multicolored

Textured” spray paint at Walmart in 239119 Sea Green. Looks a lot like the old Radio Kit color of yesteryear. Now here is where my unprofessional thinking logic really kicked in. I figured if Momma sent her beer-drinking hubby out to paint the patio furniture, he is going to use the easiest product on the market. That way he can get back to cooking those steaks as soon as possible. Just what I needed. Very little prep, quick drying, very forgiving, and really nice
results. Just be sure you spray outdoors and away from fires and flames.
This chassis prep progress will continue. Watch for future blogs.
Just remember, I am no expert, and simple share my ideas with you. This takes time, and would appreciate it if
you share with friends, just include a little note this was first seen on Pastime Projects R3tr0rad’s Blog page,

“LookMa” 12K5 Oscillator kit gets Review from CQ Magazine

April 8, 2014

Pastime Project’s little 12K5 “transmitter” kit was originally written up in May 2006
CQ Magazine. Seven years later Rich Moseson, W2VU, Editor of CQ Magazine, writes of
his experiences with the Kit described in the original article.
It is highly recommended reading. You can learn more at http://www.cq-amateur-radio.com
We still sell the little kit on our web page. It can be useful as a code practice oscillator
by listening to the output in a nearby receiver. Great fun constructing and following
the do-it-yourself instruction manual. Please read Rich’s article. Visit http://bit.ly/1lI0hlp

Assembled and Tested!


The new Pastime Projects 6V6 transmitter kit has been built and tested as a prototype. The difference between the prototype and the production models is the chassis. The metal chassis on the prototypes was machined by hand. The production chassis are cut in a high pressure water jet precision tooling machine.

7 or 8, and when they ship we will start packing the production kits with parts, manuals, and instruction manuals. This design is based on conventional handbook
