Why is a woodruff key used? Why not a splined shaft?

Woodruf key is easy to clean and remove.used only for binding.splined shaft has more contact area and used for power transmission.

Mohan, I disagree with you.

Been some time since something was posted? I am sure all the oily hands out there must be wanting to see new one.
Please stand by for a ............... Tiger.

@sanjayrai55 sir
Cheaper and easier to make.
Can do power transmission too.
In my Royal Enfield Ensign 150cc (1956), the clutch housing is mounted on a tapered shaft and keyed with a Woodruff key.
Only problem is the key shears if the nut is not locked TIGHT.
Carried a Woodruff key in my wallet for many years.
(Along with a Horlicks bottle in the knapsack to collect the oil when opening the clutch cover)

@flyingboxcar
Apologies for sidetracking.
Just noticed you started this thread long ago.
Will try to stick to the theme.
Regards

Oliver, Super, Thunder?
Triumph?

Well can't afford a Triumph Tiger, and this being a model engine thread so you can leave that guess.
Thunder Tiger.. The only one I have is their early production 19 with a cross flow scavenging and baffled piston. And not considered very attractive or collectible or even usable.
Super Tigre ..... I must confess I have none   

Here's one.
Hasn't been taken off the cupboard top in more than a year due to electrics.
Maybe fly glow this Sunday.
Must spit and polish before then.
There's a story behind this engine...

Yup, saw the trainer in your ''mess'' picture. What is it? A PT 40?

   
have two of these ,
one new but run once and one unused , in box

@flyingboxcar
Sir,
Did you notice that your 'Engines' thread
Has been attracting over 30 views
Every day
For the last more than 1000 days
Wow!

Yes I know, and think this thread could possibly be the single thread with highest view, but unfortunately with the current electric wave, the interest in engine and engine design is fading. 

The roar of engines , the charm of engines , the mess of engines , the head aches with engines and the challenges are enjoyed by only a few now a days. Old timers may still do , but the conveniences with the electrics definitely influences even the die-hard engine fans.  (Contrast from what is going on in their full size cousins - like in the automobile world - the shift becoming inevitable here).

Well in my opinion engines are the real deal using electronics doenst have  that feel
Its just a normal flying
When engines roar its different

We should agree, that majority of the population(US) were inspired and took this hobby after seeing a engine based plane in flight, not a Dumb electric plane.
At least i do.

Time for update on the promised Tiger. My example is lightly run on the bench, LNIB OT Mk III, 2.46cc.

So here you go with the pictures.
1. The bible for Oliver Tiger engines. Good read and highly recommended if you love OT diesels
2. The box views
3. Instructions

Instructions continued, and the side views. Note the serial number and "Mod" on each side of mounting lugs

Engine views

Some more, on packaging, the transfers that came with the engine (My example has the transfers missing).
Details around factory mod to the engine (These are from the book)

Pictures from the book on modified OT MK III, 2.46cc.   
Fuel and prop recommendations

An OT advertisement, and lastly how about showing off your OT? Put it on the bonnet of your car

And if you are interested in some OT MK III reviews, refer these. The second link also talks about works modified engine, as in my case.
