I've opened this thread to make a place for some pictures of motor vehicles - interesting or attractive or just simply curious. I've started it below with three pictures taken at a steam rally a few years ago. I've got a few more but please feel free to contribute pictures.

Nice link Stanley , thanks, ..........and there she is again !. You could be right about the JAP engine , although it looked somewhat bigger than those I've seen in (on) Morgans , and at 4.2 liter, it's a monster...! Softuvner seemed to think it was an experimental Riley motor.......I didn't get a chance to ask the owner...maybe next time.
A JAP engined Morgan went down our road the other day.......what a din.....and looked great fun.
I've got a soft spot for HotRods too and there were a couple of good ones there.........will post a couple of snaps if anyone would like to see them.

I think you may be right, it doesn't look like a JAP, too rough. Have a look at this, apart from the video it says that the engine is two cylinders of a radial aircraft engine grafted on to a Riley crankcase. Sounds feasible to me.

Yep....Thanks Stanley...... there's quite a bit on YouTube about Thunderbug . I should've looked before , but I've just spent some time on there and enjoyed it
As I said I have a soft spot for Hot Rods ,as well as "Straight" classics ....here's a snap of another favourite from the other night.

This sums up the evening event.......People line the road out of the village to see (and Hear) the cars and bikes leaving.
There is applause , jokes and a general good banter.............
This guy had managed to seal in the rust effect (actually most of the patina was genuine)......There were holes left in the spotwelded seams , and no trim etc . A great Car ....and quick.!

I used to shoot rabbits at night with a 10 bore shotgun through the open windscreen of an Austin Ruby while my mate drove. I blew his radiator thermometer off one night and he never forgave me! The one above reminded me...

I'm glad they didn't put Stanley in the RAF and give him a WW1 biplane, lord knows what he would have done to the prop!

They used to put metal shields on them to save them from being shot off didn't they?

You will be aware Stanley that in engineering there are three recognised ways of doing things, the right way, the wrong way and the French way.
If I am not mistaken it was the French who came up with the brilliant idea of armor plating the prop! Also, IIRC, in practice very few round actually hit the quite little deflector.

I remember reading a piece about the problem somewhere and it was fascinating but they never described how the inerrupter gear worked. Mind you, the machine gums then had a much lower rate of fire and I remember being surprised when I found out how low-revving the engines were. I saw a Merlin in the SM once and the plate said 1500rpm, 1750 emergency. The early ones must have been much slower.

Stanley, I expect the interrupter gear would have been quite simple.
Now that Merlin, were they a geared engine? I think there is a speed of around 2000 rpm that is 'best' for props but I cant recall the theory around that. I got a chance to look at a WWII Hispano engine where the crankshaft was geared to a hollow cam shaft that ran between the cylinder banks and the prop was connected to that and hence turned at half crank speed. The hollow cam shaft housed the gun barrel (which of course did not turn!). I suppose all the ones that fired through the hub used the same basic layout.

I had a look at this site and funnily enough it quotes higher rpm than the plate on the one I saw. I don't think I would be mistaken, I have a velcro memory for stuff like that. It looks as though they were all direct drive to the prop.

Stanley, I think there were a range of Merlins made including ones to go into tanks which presumably may have been built for a different rev range.

That gave me a laugh Tizer - could just picture it!!

Shooting the prop off a bi-plane sounds, to me , like an episode in the (mythical) book "Biggles Flies Undone ".....!!

Have a look at this Brad, evidently it actually happened. Good article on synchronisation of guns and also explains how they managed to stop ball turret gunners shooting the tail off their own aircraft. Lovely stuff!
