2 steps forward 1 1/2 steps back … The first monocoque casting had excessive length for the eng compartment chass horns - mostly because i wasnt sure how much space i needed for the engine and the exhausts … but now i know so I’ve surgically removed (sawed off) about 3 scale inches - the monocoque is now very close to scale spec …

Ok - you’ve reached the - i can’t drop this anymore - stage ….

Yup

Pairing with a turntable or a tape deck / or both ??

OK - i get it now low speed - rubber supported on a brass or metal rod create the slot and then open w sand paper a hack saw blade mite work ? source for hard rubber tube ?? Amazon ?? its about 1/8 dia ???

what they said ... the rubber boots - the slots are made - how ?? a hack saw blade - or a tool - or a - what ?? maybe an abrasive cord ??

This engine mount plate was made from two pieces of .012 Evergreen sheet - its different than the part on the Tamiya 20th scale engine - that part is accurate for the fuel injected engine but not for the ‘62 Weber carbed 25

Bitchin’ Camaro - by the way The Weber carbed Lotus 25 had a special Lucas spark distributor that utilized a generator mounted as pictured - this went away when the engine was converted to fuel injection - think - not sure - that this arrangement would have been used on the Lola and Brabham

Trust the process…. …

Gracias - the cams were driven by chain drives - the chain drive covers are set-off - matching the cyl head set-off - again - the Tamiya eng helped me with the shape - it’s pretty accurate here - the cam cover bolt casings are made by shaving .020 Evergreen rod down to a half round and then liquid gluing to the casing …

What a save !!

Features on the left side of the block and sump - the bolts are Master Club resin

From the No 10 Edition 1962-63 Automobile Year pub … as first installed in the Cooper - by the way - the book was published with this picture reversed - thereby confounding generations of modelers -

The Tamiya 20th sc Climax engine lurks in the background - mine will be the little brother - or sister?

Hi terry …

By adding about a scale inch to the height of the block i raised the cyl heads and exhaust manifolds - so the exhaust pipes can skirt the chassis panels on their way to the collector above the suspension bulkhead …

Have to make the engine as close to 24th as possible - because it won’t look right unless it fills the 25 monocoque - but it also has to fit within the body work - so i’m adding height here and trimmimg there - in the end - my Climax DOHC eight will be scale … fluid …

Hope this works …

While the Tamiya eng is nominally 20th scale engine- its actually downsized to fit within the kit chassis and engine cover - so i’ll try to use the exhaust manifolds - and maybe the exhaust pipes - this way i can figure out the cyl head height - as the exhausts must clear the chass extensions left and right …

Fine pl …

The cylinder heads need to be staggered - right ahead of the left - Tamiya got this right -
