Not just the Tamiya engine - this is a drawing of the engine - as installed in the Brabham

hey - who's that guy with the white hair leaning into the eng compartment ?? - looks like he went looking for the engine and just found it ! ... ..

The Tamiya 20th scale engine is decent - its parts will help guide me for basic shape and size - and there are a few 3 view drawings and cutaways that are helpful - plus a side elevation drawing in Bamsey’s excellent Haynes book on the 25 that is small also helpful …

No one has ever made this engine in 24th sc - excepting the rare Christian Goul Lotus kit - not Tamiya - not Heller - not AMT - no one …. These engines were found in period Brabhams, Coopers, Loti, Lola - so it’s worthwhile making one …

Wait - the 25 needs an engine, right? here’s what the Climax 1.5 litre DOHC eight looked like in the 1962 season 25s - Weber carbed - fuel injection was under development but not yet ready …

Modified and used 4 of the gauge housings that i sawed off of the back of the Tamiya casting -

This shot - just to show the forward tilt on the dash

If its evergreen to evergreen or evergreen to Tamiya plastic - its Tam thin liquid glue - if I’m gluing plastic to resin - it’s CA glue - med or slow -

The dash panel is made from .012 plastic sheet - using the Tamiya kit dash as a rough guide -

The frame in its new brackets sits much closer to the lip of the cowling … within a scale inch of where it should be - i’ll take it …

So i had to remove the brackets cast into the each side of the cockpit - a major pain - and make new ones out of Evergreen L shaped strip …

The brackets that secure the frame were too far back on the monocoque - so that the frame was about 4 sc inches behind the lip of the cowling - it’s supposed to sit just under the trailing edge of the cowling …

I created the frame fr the kit bulkhead - with the forward facing tilt for the dash surround - and then realized that i had made an error when i made the monocoque that needed fixing..

Fr Karl Ludvigsen’s great book on Colin Chapman … this drawing shows a feature that is not too noticable in most drawings or photos - the dash is riveted to a steel frame that bends forward above the scuttle - so the frame is not flat … so the dash is tilted a little to improve line of sight for the driver … the Tamiya part is flat - oops …

The dash bulkhead fr the Tamiya 25 kit - although the kit is nominally 20th scale - i’m modifying this part to make my part - but …

Making bulkheads - the green one is modified fr the Tamiya 25 kit - the tabs on the second bulkhead will hold magnets - w magnets at the back of the body cowling - to secure the cowling -

Ooph …

Even though no change in track / the chassis tubes appear to be farther apart - do you agree ??

Cool - looks like these Cobras were built on wider chassis frames - probably easier construction and safer and maybe even better handling ?

Yup

Well done, too old !! are the E - M Cobra kits still available ?? got any Cobra builds to show us ?? any scale !

Ace - remember - only use if you have enough for all of us - sharing is caring
