Porche 1/8 scratch build
« on: July 26, 2019, 08:34:54 pm »

Hi all well some of you will know with the move I have a new job and that job is working at a company which restores classic porches at the moment there are 16 different porches in our workshop worth 27 mill I'm sooo loving the 904 and would love to build one. I've never done a scratch built car ( loads of ships but never a car) I have no idea where to start but the average turn over is 3 months so plenty of time for measurements I still have to get a modelling area but negotiations are going well. Any suggestions where to start with making the body.

Cool - What are you actually making?   A looki-likee block-of-wood body with wheels or an RC car or a detailed model including interior & engine?   Suspension?  Rubber tires?   Working engine?   Opening doors/bonnet?  How far are you planning on going?

I've seen a guy making model car bodies out of copper sheet and beating it into shape and soldering it all together.

How about like the real thing most new design cars start out as a block of clay.I went to the test trough at Dumbarton where one of the Clyde shipbuilders(old age moment the more knowledgeable please fill in name -----------) tested there hulls a props ,There hulls were also made of clay .When they had it right the then used the model to lay the hull up. It is annoying when I can not remember the company .
just a line of thought.

There are lots of plastic and metal models available of this car - I'd suggest buying one so you've got a workshop memory jogger and something you can hold compare to the real thing and feel and rotate it in front of you to get a feel of how it all works close up.    It would be useful to see how they solved all the small details in their design - you might spot some obvious errors before you fall into the same trap.

With reference to the copper sheet method, there was a tv programme a couple of years ago about a bloke who makes model cars on commission - mega detailed - he made a wooden buck to create and fit the panels around - the subject of the programme was him making an 1930s Alfa racing car.   Each one took years!

Thanks for the advice, I'm thinking of going detailed full engine suspension and so on, I'm expecting it to take a few years.

Here is an interesting comparison between a 904 and a Caymen. It makes you realise how much bigger cars have become over the years.
Not just Porsche, but even my dads old Mk1 Escort is tiny compared with today's Escort.

And today's Mini Countryman is BIGGER than a 1969 Maxi, which is totally ridiculous.  :o

I had a friend into model railway steam locomotives - he always said that when he retired, he would build one.    I went over some maths with him.

We guessed the engine (Evening Star) would be made of probably 5000 individual parts.

If you worked on 1 piece at a time and turned a piece of base material into a fully finished part every day, it would take almost 14 years - non-stop, every day, no holidays.

if any part could not be finished in a day, the project would drift on longer.

He bought a kit instead - fettling & painting only.

I think you're maybe referring to the Denny Test Tank in Dumbarton.  Not been there for many years (my old uni, Strathclyde, took it over before Glasgow uni got involved) but from memory the hulls were cast then carved in wax, and GRP mouldings taken if required.  Dunno what they use these days.  Maybe clay now.
