Jag V12 bottom ends (YES ENDS plural)
Well, Ive got this little idea on the go at the moment, and it was just a thought for a bit of an hmm project. So I might be looking for a couple of
jag V12 bottom ends (staight and preferably not knocking). Definately don't want any heads or ancillaries, flywheels, drive plates. Probably
wont want sumps, but not sure at this stage. Front pulley's will not be required, but the bolts at both ends might be an idea.
So, IF anyone has some and wants to get rid of them to me for preferably zilch then let me know. IF I can get this plan together then I might be
building a bit of a beast of and engine. And NO it wont be a big V or an X.

Ok then, recreate THE Napier Sabre H24 at approximately 1/2 scale.

They are really heavy, I had a couple of v12's jags XJ12 & XJS also ran a manual 4.0litre XJS for a couple of years, faster and a lot more
economic.

Didn’t Clive have one? Don’t suppose he took it to Malta?

Yep The Napier Sabre Engine IS a BIG and HEAVY engine. About the same capacity as the Roll Royce Merlin, but, the Sabre had an awful lot more horse
power (over 3000hp). Original engines are nearly as scarce as rocking horse do do's when NOT sectioned. I was thinking. why not try and recreate
one using available parts. The Jag V12's would supply suitable crankshafts, connecting rods, pistons and crank case's. The cylinder blocks
could (possibly) with some modification, be utilised, in conjunction with top plates (to direct coolant) and individual cylinder heads. the rest of it
could be worked out.
 
H24 sabre engine real
 
H24 Sabre engine art work
When complete you would have a part scale Sabre of about 12 Litres no bigger in reality than a V12, but 24 Cylinder H pattern that would be a bit of a
head turner where ever it was run, be it car shows or airshows. But it would not have the million pound rebuild cost that a real genuine Napier Sabre
is likely to have.
Just my thoughts. so IF anyone does know of or might be interested, ..............................................................................

Could the BMW M70 be an alternative as this is an aluminium block and are available off ebay. The M70 has no vanos, the M73 which is more available
has single vanos but if you are chucking that way then it may not be an issue.

ok... so this sounds a lot of money & time to make, I'm assuming there is some purpose to this? You must have some machine shop to pull this
off.

Well, why not. I've not got a lot of money, no money to be honest at this stage. I have time, I have pressence of mind and a degree of
intelegent thought. The purpose, why not and belief in my abilities and those around me. Also it's about a belief in this country to try and
proove that IF we put our minds to it it CAN be done, current thinking by a lot of people is or seems to be 'oh crap we are in a mire and we
cant do that or the other because we are too scared or have no vision and I dont want to risk the £1 I have in my pocket/bank/mattress'. As for
machine shop, well they did it in 1940 and they didn't have the tools/machinery available that we have now.

And the sleeve and operating system, well, the sleeve are just cylinder liners (with cut outs for the porting) and are operated by a gear and rotating
crank system driven by hollow shafts that carry a drive rod to the rear of the engine. Simples (shnick). The only part which I am still considering at
the moment is the block/crank housing assembly.

Trying to recreate a scaled down engine like a sabre from parts of other engines, ok lets see how you get on, I for one will be very impressed

I would start from scratch and build a model engine of about 25mm bore ,given enough time most parts could be fabricated from machined parts by
brazing or milled from solid.A number of aero engines have been built from scratch including merlins and bently rotary engines but it is a completely
different matter to make something full size.

Well Paul, the start from scratch model engine IS already underway courtesy of a chap (down south I beleive) of Clem Tomlinson, he just loves the
napier engines. You will find his progress down the bottom of the link page.
