Back then I was making bulbous symmetrical and asymmetrical end caps to accommodate 0-72" curves. These modules attached to 4' X 8' platforms and permitted running larger engines and cars with the simple addition of a switch added at each corner to run off to the large sweeping 180 degree plus return curve.
Not sure of the year. I do remember it to be a product announcement or review, not one of my ads. Some where around early to mid 2000s.
I found the most success in doing local shows. Magazine response was very good but it proved awkward to service clients in the manner which I preferred. I did ship to the West coast but I like to micro manage the set up.
Since moving, closing shop, selling my molds and dropping my web site I took my cue from Matt Jackson and seek to share my experience and insights online.
