Whittle Aero V8 WIP

[cobra428]

Hi Guys,
Well, I made my decision on the next build. The H/M is running good and is ready for the bling. So while a wait for the paint to dry I will get back into making chips mode. This build will not be like jumping into the deep end but more like junping from a 20ft tower into a kiddy pool head first :big: But, I want to give it a shot ;D

From the Hemmingway site
The V8 Aero Engine V8
This elegant V8 won ME Magazine's coveted Gold Medal
at the 1995 Olympia Exhibition. A truly magnificent
project yielding a 10.6cc 4 stoke glow plug engine that is
guaranteed to turn heads wherever it is displayed or
flown!
Recreating an aero-engine layout that was popular in the
1920's, Eric Whittle's masterpiece closely resembles the
Airdisco (Air Disposal Co.) 120 and 200 hp units used by
Sir Geoffrey de Havilland in the DH51.
The engine will swing a Ø12" x 6" propeller at 7,000 rpm
yet idles smoothly at 2,500rpm. The engine is just 4½"
long with an overall weight of 15oz! With a 90º V8 layout
using overhead valves actuated by push rods, the engine's
bore x stroke = Ø0.460 x ½". Mr. Whittle states that this is
a straightforward engine to build, requiring no special
skills or equipment. What is required however is patience!
The award winning engine took 6 months to complete
and contains a total of 550 components. Fancy a challenge?

So there it is. Hopfully mine will look the same!

[cobra428]

Well tonight I've been a bizzy boy. Paint on the H&M and the start of the upper crankcase of the V8.

So here's some pic's of the V8 build

Face and debur side one

Second side faced and sized 2.850 mine 2.855 (room for polishing)

First top of block cut (flycutter looks like it should be making tunnels in mountains)

Finished 1st cut

Set up for second cut

Second cut done

Hope I got it right

Well that's it for tonight

Tony,

Very Nice. :bow:

You may find it easier when you machine round to square to put a smallish Vee Block between the moving jaw and the round section. It helps to hold the flat evenly against the fixed jaw and copes with any tendency of the moving jaw to lift.

Best Regards
Bob

 

[cobra428]

Thanks Bob,
It did take me a while to get the flat to lay "flat"

[putputman]

Cobra428, it didn't really dawn on me how small this engine really is until I saw the size of the upper crankcase block. I then went back and read your intro again. 4-1/2 long.
This is going to be a very interesting build to watch. Keep the good photos coming.

 

[cobra428]

Putputman,
These are the "big" parts I'm doing first. Should get real interesting when it comes to the small stuff :big:
Like everything else in the engine scratch.gif

I am loving this thread!!

One question? Is it going to be blue with the distributor in the front?

Best of luck on this one and dont forget to make two of everything so you will have something to send me for christmas!

 

[RobWilson]

Hi Tony will the engine be going in one of your planes when built?
Rob

 

[cobra428]

Hey Guys,
Thanks for the encouragement. I'm thinking about putting it on a plane. I think I would be to scared of planting it though. I haven't crashed a plane in a long time but....... you never know (strike the last remark..the second you say something like that....). The engine is usually the first to find the ground :big:
It would go in this plane (~ 40" wing span)

Steve No distrib.....Nitro Burner (glow fuel) Only George B could make a distrib that small ;D

Somemore pic's of tonight's endeavors, Tomorrow the lower half

Nice work there Tony,can't wait to see the progress and see it running!, interestingly enough, my grandfather, Philip Brown, was for some years, a curator of the shuttleworth collection and worked for a time before with Frank Whittle on the supermarine spitfire, he passed away around 1971, his father was Mr. Brown of "Brown and May" of Devises UK if you google them, there are still 30 or so of their engines still working around the world!
