MCM Ohana (6/6)
-
A concession to scale - the front shocks are glued to the front of the chassis legs - so I’ve added small tabs to grasp the ends …
-
Over the years I’ve photographed a number of 91s and 122s. The first shot shows how the front of the shock attaches to the frame - the second photo shows the shock mount that holds the trailing end of the front leaf spring …. Going here next
-
All these additions are made with Evergreen strip .20 and .15 - and Tamiya liquid glue ..
-
The forward section of the chassis is exposed and I’ve got to add some parts to correct scale width and for strength - I think the chassis longerons (think that’s they’re called) are a bit too wide on the Etzel chassis - but mine are too narrow …
-
This shot compares the Etzel 25th scale Miller 91 chassis casting to my 24th 122 chassis master - the main difference is the chassis length - the difference in width is minimal …
-
The front engine mount is a cradle that was used for the next 40 years by Miller and then by Fred Offenhauser - I’m attaching it with some bolts which is spec - and will be secure … the Miller race cars site has a wealth of photos - found one of the crank case cover - showing the fins and bolt pattern …

Castings for the undertray and the engine mount
-
The engine bulkhead was a complex part to make. The shape is dictated by the shape of the supercharger, which was attached to the back of the cylinder head …
-
Gracias the body casting has some thin film to remove in some openings - the film is from thin plastic - this helps the caster get a clean casting and allows the mold to be opened without tearing the rubber…
-
A few more of the master parts and a test shot / casting of the body and chassis …
-
So the parts were finished some years ago - and then given to Harold Bradford - “Brad” - to cast - when I learned that The Revs Museum had a “sister” 122 - the 1924 “Boyle Special” - well of course I couldn’t make just one …. Brad immediately set about casting the parts - just kidding- he actually stays pretty busy filling orders for stuff he has sold for years - so the parts sort of languished in his basement until I showed up again and convinced him to let me cast the body - the pix aren’t so good but the casting turned out well - and Brad agreed to dive in and cast the rest …
-
I made all of the basic parts - including a nearly complete engine and drive train - Gordon White gets an assist here - I exchanged some emails w him and he explained to me That the Miller 122 cylinder heads - 2 x 4 - were very nearly the same physical dimensions as the 91 cyl heads .,, but that the crank case was larger - this info gave me confidence to make the engine in 24th scale … this is a shot of some of the master parts with tabs added for casting - this is where Harold Bradford enters the story …

Did I mention that this has been a "long term" project ?? I had done some of the early master pasts 8 / 9 years ago. Miller was featured at the 2013 Amelia Concourse - my first trip to this wonderful event - and my most trusted assistant is holding the chassis and body master parts in this photo ... great opportunity to photograph half a dozen Miller Indy cars - including the Junior Special ... so my 24th scale Miller 122 was "featured" at the '13 Amelia Concourse - although only for about 1 minute ...
