Chassis and shaker plates were ‘de-horned’ with a Dremel wheel. Parts were media tumbled polished for three hours. Parts were degreased and sprayed with a light coat of clear lacquer paint. Any shaker plate/chassis fit conflicts were identified and corrected. Front shaker plate pin tubes were ground back to insure no motor brush barrel shorting. Chassis numbered on top side, shaker plate numbered on bottom side, motor numbered on label to correspond with car body number.

Completed chassis inspected for ‘squareness’ of wheel contact. Pickup wipers set to allow front wheel track contact. Each chassis run on 55 LF Bowman road course for final adjustments. Bodies individually fit to chassis. Tape applied to inside to prevent paint scratching from shaker plate. Finished units test run again.

Builders Notes:

First off let me say that I owe Ron “Toybaron” Bernstein a big thanks for giving me the privilege to work on another Limited Edition Project. Ron’s love of the hobby is persuading and infectious. He is truly the hub in the wheel for all of us that have the opportunity to contribute to the hobby – specifically brass based cars.

My involvement started innocently enough a few years ago in my search for Tyco Pro Type One black pan chassis parts. After a few phone conversations Ron asked me “Have you ever run a Riggen?” I believe my response was “no, but give me a little time and I’ll get one from you.” I think I ordered one within two weeks.

It took me a little bit to get that first chassis to have some good track manners. But when it was finally set up, I said to my self “wow, this is what a slot car should run like.” It reminded me of the old days with my older brother running the 1/24th scale cars at Dan’s Hobby Shop in Tampa, Florida.

This particular Limited Edition was inspired by Richard Picard who has also contributed – in a far more technical since – to Ron’s efforts to re-popularize Riggens and brass pan cars. I have two of his ISO Riggen based chassis' and consider them small treasures. Richard was the natural choice for the chassis modifications for this project.

As anyone who follows the HO racing world knows, there has been a movement away from heavy magnet cars. These include G-Jets, Thunder Storms, and P-Jets from the major suppliers. These cars are the basis for real IROC style club racing.

My intention with this LE was not produce cars for ‘sanctioned’ races. The series is, however, intended to capture the spirit of IROC’s golden days from 1975 to 1979. Jairus Watson created the paint interpretation for the era in the Scale Auto Z-28 Camaro lexans.

The parts selection reflects somewhat my outlook on car setup. I’ve found this receipt to be highly pleasurable running on my Brad Bowman road course at 13ish volts with a DeFalco controller.

One positive outcome that I hope you will get is the desire to build for yourself a set of cars to race and wear out. If you have never done this, I know you will learn quite a bit and in the end have a sense of deep satisfaction. With the Picard modified chassis as a starting point, you will be able to select motors and drive lines, and pick-up systems that best suit your needs.
