Not a lot of physical progress of late but some good design work (140+ drawings now completed).
More importantly though I have received my certificate of Design Right from the Intellectual Property Office which means my work is now protected out
in the wide world from people who might use the plans to make money for themselves.
Although its only a certificate it feels like a big milestone

Cheers Chris.
I have had a few people ask when plans are likely to be available for Purchase, the current aim is end of February. I have a couple of chassis bits to
draw and a few body panels and that's it. Once done its a case of checking, locking things down and then making up nice folders full of drawings
and info ready to send out.

Did you find this a fairly pain-free experience?
I must admit, I've previously relied on the protection of the 'automatic' design right you get under law, for non-patentable
designs, but of course it's much more difficult to enforce. For the sake of a few quid (£60, isn't it?), it sounds as though it might be
worth pursuing?
Did you identify/annotate specific, unusual features, or is it 'just' the overall look-and-feel that's protected?

Just been having a bash at the secondary part of the project, the transportation method.
My aim is to eliminate the need for a trailer and also give myself reason to buy a pick-up, but it needed to be big enough to carry a race car which
means getting something from 'murica (which also means a V8 engine...). Late last year I found a 1995 Chevy K1500 with the extra long 2.55m bed
and a 6.5 Turbo Diesel V8:

Which according to my plan should carry the car like this:

Still plenty of work to do on the truck conversion (managed to get a winch of CHNSS1 today which has helped) but cant wait to take it racing.

It may be 6.5 litres of Detroit muscle Dan but it most certainly isn't fast!
The engine is soooooo lazy and the auto-box isn't in a hurry either. It is though a really nice cruiser, surprisingly comfy ride and the cab is
a nice place to be. At 70mph its like being in a big smooth car.

Completion and Pricing.
Just a quick update on the progress on the plans for those who are interested in buying.
I have just a couple of bodywork drawings to finish now. Then its a case of Checking and PDF'ing everything ready to sell. I've even
managed to write out some build notes.
Hopefully I can get a printer sorted within a couple of weeks with the aim of being able to send out packs by mid-March at the very latest ready for
the nice spring weather and new projects time.
Each pack will be in its own A3 folder as its going to be over 200 pages in total! I always wanted to make it a "complete" set of plans
and might have succeeded.
I would like to get a little bit of feedback on pricing as this is something that I have been struggling with. Opinion has been swinging between cheap
and plentiful ( A La' Locost Book) or priced to reflect the detail aimed at genuine builders (more like Kit Aeroplane plans).
My current thoughts are somewhere in between and with modular options:
Basic Pack (Fabrication Drawings only + Parts list): £100+VAT
Full Pack (All Drawings + Build Guide + Parts List + Calculations): £150+VAT
Build Aids (Jig plate drawings/Tube Wraps/Etc): £25+VAT
Aero Upgrade Pack (I'm talkinng to an aerodynamicist about doing this): £25+VAT
Constructive thoughts welcome.
Just wish I had some time to get some work done on the actual car!

Are you intending to supply as PDF electronic copies, or paper copies, or both?
Obviously there are potential copying issues with both, but PDF would make life a whole lot easier for you? Is it possible to protect PDF's with
individual passwords or electronic 'fingerprints', so that if one did get released into the public domain, you'd know who to go
after?
What are the 'calculations' you list? I must admit I'd be nervous about giving away that sort of underlying design knowledge free of
charge, but then you know know cautious I am about IP in general!
Its a shame you won't have a finished, proven car before going on sale with plans - I can imagine that it would reassure a lot of people both in
terms of the car's performance, and that solutions had been worked out for any issues, before they part with their money?

Everything will be detailed fully when I do a "Plans for sale Advert" properly but to answer your points (I have been thinking about this
for months).
Only paper copies will be supplied with an individual water mark. All bound up in a nice folder. The PDF's are for archiving and to print from.
I will offer a page replacement service as well to customers so if welding/spillage/fingerprints ruin a page I'll send new ones out at cost
price (IE the price of a stamp)
The calculations will be things like weights, costs and sizes. I am also going to include the suspension movement and spring rate calculations so that
people can easily tune the car.
The actual car will follow shortly after completion of the plans (~2 months) as completing the plans will free up the time to work on the car. So I
suspect only a few people will purchase plans before that. I don't forsee any significant changes now as the fabrications are nearly complete
for the Dev' car and nearly everything else is purchased.
Any changes to the plans based on the build of the car will be issued free-of charge to anyone who has already purchased the plans. So no-one should
be disadvantaged.
I plan on this being a long term project with a Phase 2.0 update coming at a later date and some concept work has already begun on that.

Jedi Wings
Cheers Tilly, hows Uni going?
Just thought I would load up probably the 'final' CAD pictures with everything now completed. I have also modelled up a set of Jedi Wings
(that I have bought for it from Dan) to give an idea of what the final car should look like. I have been using a set of F3/FR2.0 wings in CAD which
are a bit oversized.

Currently trying to decide what colour to have the chassis powder coated. Thinking I might go for Black/Carbon panels over electric blue to keep the
corporate colour scheme but highlight the chassis more:

Any idea what the torsional stiffness that you're getting from that weight is, either on FEA or in reality (have you/do you intend to test)?

I'll probably offer them to order. A couple of potential customers have asked if I could supply a chassis and the answer of course is
"yes" but I would have them made on a per order basis rather than holding stock.
Likely cost would be similar to that of "kit car" chassis plus an "MSA cage" that you usually pay extra for. Of course you
get the MSA ROPS built into this car.

Final Chassis Preparation
I completed the final chassis preparation this weekend and dropped it off this morning for Powder coating.
One of the neat features (well I think so anyway) is that the suspension pickups are all on two flat planes, which means that they can be drilled
after the chassis welding is complete and there is line of site to cross measure between all of the suspension mounting points. Ensuring that the
suspensions is aligned side to side and front to back.
This means that any distortion from welding or inaccuracy in the chassis does not affect the suspension geometry (as long as its not completely
off).
Cross measuring the front before drilling:

Cheers Dan, appreciated.
A colleague of mine has generously done some renderings from the CAD model, I may be biased but I have to say that its turned out to be quite a pretty
little car especially as it is all driven by function. I really like the 90's Tyrrell-esque colour scheme as well.
