Re: Superdetailed Pocher Monza 8C
Time for the steering mechanism.....The Pocher sprocket of Nylon is no good for a reliable working steering, neither the metal worm provided in the kit....as this project is developing, it will weigh more than 4 Kgs when finished, so a new sprocket and worm were devised & made.
Besides, I reduced the sprocket's teeth so that the demultiplication coincides with that in the prototype (From the beginning I said this was a "superdetailed" build!...  )The nylon kit's sprocket and the new parts scratchbuilt... All the particulars of the prototype's steering box are reproduced here...  Here's the "sand cast" texture you were looking for, Olivier! See ya soon... Mario

Re: Superdetailed Pocher Monza 8C
Hi!
Like this, it really looks more realistic! Impressive work! What kind of tools/machines do you use to make this kind of parts? Especially the worm gear. And could you also describe/explain how do you cast zamac? Thanks Olivier.

I use a Unimat 3 lathe with milling head and a Boley F1 watchmakers lathe for doing lots of scratchbuilt parts... The worm was made using the Unimat's threading attachment...(It's like threading a bolt but with a big thread pitch) The sprocket gear was also made in the Unimat but using a rotary table I made for it...See pics...  A friend does the castings for me, I cannot explain that, sorry! Regards Mario

Re: Superdetailed Pocher Monza 8C
Time to give the body & frame a little care....
As in the rest of this build, the body & frame must be assembled only with scale hardware....NO glues or adhesives at all, ....and this subassembly must be able to be dismounted any time.... First of all, the seat which came as one piece with the main body, was carefully cut from it, rectified and upholstered in Capretta Italian leather (VERY thin)....provisions were taken to bolt the seat to the body and frame later...(Pics 1, 2 & 3) The next pics are a pictorial sequence showing all the attachment points of the body parts to themselves and to the main frame...also shown in place is the upper engine block, which was moved to the back of the frame 10 mm...(Pocher boys glitch!!) In some of the photos you can see the upholstered seat and its attachment to the body and frame... Next time, I'll show this stage dissasembled and all its parts...  Cheereeo......... Mario

Re: Superdetailed Pocher Monza 8C
Hello Mario,
Very impressive update again, Great way of doing the seats, one question though: Is there a special reason why the reverse side looks the way it does? Is it a prototypical structure? I also think that you have beautifull tools! Very nice and professional. Best Regards, Marc

Re: Superdetailed Pocher Monza 8C
I'm doing some other models Olivier, so this one is waiting some other actions....
Thanks for your comments, jmesawitz, I don't deserve that much...  This time, I'm showing the scale leaf suspension I'm scratchbuilding for the model, the one's in the kit are a no-no... This stage was drawn to scale in Autocad, printed and used as templates glued to 0.7 mm thick brass sheet for cutting each leaf individually.... Scale hardware was used to make the leaf pack, giving each leaf the correct curvature and they do work fine!!...
