Gearboxes of the 312 B and 312 T are not usable. I made a shortened resin copy of the MFH 312 PB, which is nearly identical to the 312 B3 73 and 74 ( see my WiP of the 74th car).

Brakes are resin cast copies from a Tamiya Mc Laren.

Next step on the to do list is the scratch build of the exhaust system.
1973rd exhausts are different to the 1970 and 1974 and 1975 cars, but identical to the 1971 and 1972. At my '71st, '72nd and '74th Ferraris I made them by bending copper cables, making silicon forms and cast them in resin.
I still had the resin exhausts from the 312 B2 '71 and '72, but now I liked to try another way of making them.
3mm styrene bars were heated by a 300 Watt hot air fan until they were soft and bent to the right shape. There are only few seconds left before styrene gets hard again, so you have to hurry, but later on the pipe is correctible by heating only small sectors.

Finished parts are temporary fixed with tape.

Wow, bending those exhausts is impressive, every time I have tried this it does not work very well!

The exhaust pipes look fantastic (as does everything else) - the pipe bending seems like it would be quite challenging to get right but you have mastered that technique!

I hadn't seen this thread before.
Incredible what you are doing here. Doing these exhausts would drive me crazy!

Fantastic work, I would never have thought of that idea of using plastic rods for the exhausts
