Alfa Romeo Tipo 33 Stradale: Chassis

I gritted my teeth and glued the front and rear chassis components to the central tub.



The forward structure fits nice and snug but the rear section, including engine and transmission, floats around like crazy and the opportunities for misalignment are huge. So I used 5-minute epoxy instead of the usual 5-10 second CA glue in order to have some time to wiggle things around before it all set hard.



The chassis is a pair of large-diameter aluminum tubes that run up the sills, with a floor pan and a rear bulkhead. To the rear of the bulkhead, two tapering tubes reach back to the structure around the gearbox and support the engine en route. This was before the days of stressed engine blocks or transmission casings. Getting all that to sit square was an interesting challenge.



In front a classic tubular subframe grows out of the floorpan and chassis tubes. The kit does not feature an opening front body section, a flaw I may decide to remedy if I can get my courage up, as the level of detail is really quite nice.



The body panels all fit nicely and the car sits square on all four wheels, so things are going OK so far. Cockpit finishing and a few more details around the engine compartment are next, then on to the body and final assembly.




Stay tuned!
