Robert Roof of Anderson, Ind. was a well known manufacturer of Ford and Chevrolet speed parts. Here is a link to information about him: Robert Roof - Speedway Motors Museum of American Speed The image is my design of the OHV conversion. The head is .77" long; the valve stems are .0134" in diameter.

Here is a link for information on the Mercury Body Corp of Louisville, Ky. : Mercury Speedster - Speedway Motors Museum of American Speed BTW, Modelmartin says he still has a few speedster bodies.

I built this chassis and engine almost 60 years ago but didn't complete the model, whatever it was going to be. About 8 years ago I got a Mercury speedster body from Modelmartin and decided to make a speedster with a Roof OHV head, which I designed but because of its thin components, could not get printed. The resolution at that time could not print such tiny items. Fast forward to today and now I have an Anycubic Mono 4K 3d printer that can print details that I cannot see with the unaided eye, so the Roof head gets printed. I also designed and printed the Mercury Body Co., Louisville step plate. That illustrates the progress that hobbyist 3d printing has made in a short period. You can see this model, along with 800 others, at the ACME Southern NNL on Oct. 28.

Thanks! With CAD ( computer aided design) and 3d printing, you are limited only by your patience and amount of spare time. Here is an exploded view of the Duesenberg before printing.

This model was designed by myself in Sketchup and printed on my Anycubic 3d printer. The car was driven by Jimmy Murphy to win the 1921 French GP. See it at the ACME Southern NNL on Oct 28th.

We are anticipating about 800 car models on display; hope to see you there!

Thanks guys, attend the ACME Southern NNL on Oct. 28th for a close up view!

This is a Ferrari concept car, designed and built by Pininfarina in 1970 on a 512S chassis. I purchased a file of this car from CGTraders and modified it for printing on my Anycubic Mono X.

Place the "turnings" closer together. I used a small maple dowel in a dremel with some auto polish. Probably 4 times as many turnings.
