Emgee that particular pattern was produced by Shapeways.com in their white strong flexible (WSF) plastic.
It is 3% oversize to allow me to take a silicone rubber mould from it so as to produce the wax patterns for final casting in gun-metal.
This is the already completed other half of the job.
The WSF plastic is the cheapest form of rapid prototyping.
The amount of detail is limited but for a bit extra cost the fine ultra detail plastic (FUD) is capable of high resolution.
These patterns are scaled at 10mm to the foot for gauge1
the lettering is about on the limit , the hex nuts are 50 thou AF
and the castings
I should say I have no involvement with Shapeways.com other than as a customer.
Abby I see three customers for the castings already in these 2 pages.
Gadabout
Shedboy
Metalmad
Steamer (depending on cost)
LittleJohnny Are there any other takers so that Abby can cover the cost of producing the castings ??
PM me and ill add your name to the list. Maybe if Abby sees he can cover the cost to start then he might procede with this very worth while project.

Hi,
Why not the cylinder heads too???? I have wanted to start on a Whittle V8 ever since the article came out in ME, time is in short supply so I decided that I might never get it finished if I started, but with a set of castings then i reckon my thoughts will change as there is a little less to do(?)
regards
Mark
For those interested, and to keep up the interest in this engine, I have added a file of the cylinder head model, showing sectioned at inlet port to reduce file size to upload, use Adobe Reader 9 or better to open and click on "activate box", the model can then be moved around with the mouse for total viewing, leave "view" as default to slow movements down. Be patient when activate clicked as can take a while to load.
Rgds, Emgee
I am getting ready to start this engine myself, but if castings is in work i am interested that would help me along a little bit more for a reference at the least. Like a few on here i work better with an example but can build with brints lol. So please keep me updated on this as well.
Is there any chance somebody might be able to send a copy my way too, please? Just for Solidworks at present, and then hopefully metal when current project are completed...
Hi there, I just recently came across this particular engine. I would also love to get ahold of a set of plans. If anybody can help me out with a set I would greatly appriate it. My email is [email protected]
