1923 Fiat SB4 "Mefistofele"

I think I've found my muse ;D
It's rather a long beast - any suggestions on how best to alter
the proportions to keep in line with the general CK footprint?
Any suggestions on software that can quickly rescale an image
based on, say wheel diameter??

Knocked this up in Sketchup in my lunch break - looks about
right although I'm gonna need to remeasure the workshop ;D

With mine, I brought the image into Sketchup, drew a rough wheel
to the correct size, and then just re-sized the image so it
matched the wheel sizes. That then allowed me to draw out the
profile shape at the center of the image, them move down the
length of the image, extruding each section, re-sizing the
extruded face with each section, tweak the profile and repeat,
down the length.
I hope that makes sense, but let me know if you'd like to see
the tutorial video I used.

Thanks, that’s kind of what I ended up doing too!
I think my rear axle is a little close to the seat back, short
of fitting the chain drive externally… a bit more tweaking then
I think I’ll start on the CAD (cardboard aided design) stage

I found a pretty good sketchup model of a GX200 to use in mine,
which allowed me to shuffle the axel and brake around to clear
it, and make sure the ley-shaft will fit. Let me know if you'd
like a copy of that file too, or my steering wheel.

Hi Konrad,
I'm just measuring up for my Cyclekart (Aston Martin - Green
Pea) and would appreciate a copy or link to the Sketchup
tutorial and GX200 model

Hi Steve,
Typically, I cant seem to find the exact video I found before.
This one shows the concept:
HTML https://www.youtube.com/watch?v=miY_xtSEcOA
It's method number 2 in the video, except I did it horizontally,
rather than vertically. I did it in stages, starting from near
the center of my car, using a side-view and and end-on view
profile, over-laid at 90degrees to each other... select the
end-view profile face, push/pull it to around 10cm deep, resize
and move the resulting new face (leading edge only) so it lines
up with the side-view profile, then push/pull that new face
another 10cm and repeat. I hope that makes sense, but feel free
to PM me if you'd like to talk it through on a video call or
something.
Here's a link to the engine model:
HTML https://drive.google.com/file/d/1QRbW1YaWH-Rrv45uTSG24WuWuPCRQy6y/view?usp=sharing
I put an image over-laid onto it, showing the dimensions (from
the Honda website, I think), so you can check the scale is set
correctly for you, and then delete the image.
Hope that helps,
Konrad

Thanks Konrad,
Found a suitable model of a GX200 in the SketchUp warehouse
(Wasn’t to scale, but sorted that quickly enough). I think I’m
as close as I can on screen.

I love your inspiration car! You have an excellent profile
picture of the car to work with, so you have a great starting
point to scale and downsize from. Start with the wheels and
tires you will use or cardboard patterns of them. Place them
against a wall at the proper wheelbase you will be using, then
draw a paper or cardboard pattern on the wall adjusting the
length of the hood, frame, tail and seating area until you have
a shape that works well for your visualization of the car. This
also allows you to adjust the ride height and seating/floorpan
location to help with its center of balance. Plan on too much
seating area, it is easier to make the seating area smaller than
it is to make it bigger.
