what happend with the engine carriers radius ?

My drawing clearly shows an end radius of 80mm not 60mm
Please explain the other errors you seem to have found.

Please explain what you want to show us with this strange drawing as this can hardly be considered an image of the real thing.

first question mark left , what is it for ? I can not see it in any foto .
second question mark , radius in the drawing is 60mm . I think it must be much smaller .
third , is the original tapered ?
the radius in my drawing looks like 60 , but it can be a coppy mistake . In " Schema De Carrosserie N 035 " it shows 80mm .

nobody knows anything about it? I found this fotos in the internet .

Please remember, when I make drawings, I do them to build something. This drawing, though strange to you, is wonderful to me. It is a drawing of a T-35 frame, to Bugatti drawings, but modified to cut panels that will later be formed and welded into frame rails. The small triangles cut into the rails are registration points and places to clamp the panels together when welding. Once welded and ground, the frame looks very much like a stamping. That's what I wanted to show you.

It was very obvious and not at all strange to me what the purpose of your drawing was but I wanted you to explain to the less technical educated Forum readers that this had nothing in common with an original chassis drawing. Thanks.

Nobody can say anything about the t41 chassis questions ?
first question mark left , what is it for ? I can not see this part in the foto . Greg ?

what was the question?

look in the cad drawing . the top drawing with the 3 question marks . The cad drawing I made looks a little differend in my computer , but why ?
530 mm from the front , what is it for . I can not see it in the fotos .

The 530 mm is the break point for the taper. The brackets underneath were not used as the radiator mounting method did not use them.

so the 2 70mm wide brackets for the radiator mounting are only in the drawing . The real car does not have them .
What about the engine mounting brackets ? In the drawing the bracket has 60mm Radius . It looks to me the real radius at the car is smaller .
And the taper at the end of the chassis ? Is there a taper ? Or is the taper only in the drawing .

The rads on the engine mount tabs are correct and the chassis does taper at the rear as in the drawing.

are the 2 front ends parallel ? Or they are bent outwards ? If I take the 512 mm and ad 2 times 65mm I get 642 mm . The front shows 650mm .
