Dunno, don't have classic bike and their web site doesn't list content.

What is the article about ?

Probably are more John Stevensons around, great grandad Sam had one of the first ball bearing push bikes around here, meant he could get round a lot faster……………….

Yes then it's me [ guilty, hand in air ] not seen the article but had a lot to do with Dennis and his bikes, even owned two at one point in a previous life.

Need to nip down to W H Smitt GMBH and peruse a copy when I get a minute.

This is a picture of one of the twins.

Used to rev to 11,000 rpm in 1948, not bad for a shed built special.

He was also the brains behind the Myford Moped.

The old TX1 Taxis used Nissan 2.7 diesels with no chain or belt

500,000 miles is easily reached and surpassed by an owner, the reliability is phenomenal with lots of low end grunt

Top speed isn't much to crow about but if you want to tour around the world then go to the moon and back without any timing belt issues ever arising it's actually a great system

Wonder if anyone ever squeesed one of those into a bike?..seen pickys of a bike based around a 500 bhp dodge viper v10…..intresting ….

Always fancied using electric in a bike….unfeasibly high accelleration which seems to be the thing for bikes…

Hi Alan,
For those that do not know what the Deltic looks like here are two pictures.

I remember when I was at school being taken around the English Electric factory where these were made. (Photographs taken at York Railway museum.)

The place I used to work at tested many Deltics for the Royal Navy – I would often go and have my butties within earshot. I used to be involved adding instrumentation to them too. Miss them!

I seem to remember that the RN shipboard Deltics were fitted with cartridge start systems?

I'm not sure – but I think these were started by compressed air, I had nothing to do with the actual engine runs. Most info was second hand, they were fitted to minesweepers with GRP (handy!) hulls I believe. Rolls Royce would rebuild and repaint them, and then to us for the test beds, then off to sea.

Cheers,

Mike.

Just to keep this thread "On Topic" as they say elsewhere, and bearing in mind the number of model locomotives made here, remember that the Deltic was also a very successful locomotive engine, with the loco's even being named Deltics. Just my 2 Drachma while I am logged on.

Hi guys——— my last post on this particular thread 'coz we've wandered "off topic " a bit, but hopefully you're looking at the "Phasing" end where the three cranks and auxillary drives are all combined ?? You can see why that original picture brought this to mind ??—————-<a href="http://tinypic.com?ref=2zjj8qx" target="_blank"><img src="http://i47.tinypic.com/2zjj8qx.jpg" border="0" alt="Image and video hosting by TinyPic"></a>

The Deltic was 3 Junkers Jumo engines with an extra gear to make one crakshaft turn the opposite way.

ME has featured Clen Tomlinson's "Clentec" Deltic-configuration petrol model

(I wasn't sure of the name but after typing it google auto-offered me 'clen tomlinson deltic' – that's fame for you!
