OK already the once again enjoyable Bristle Bilvedere

Thanks Terry, when I looked there was only one picture showing the blue screen but after reloading it from file it seems OK now

 

I wonder if postimg.cc is going defective on me, they seem to want to take on Paid For images these days, maybe this is a non subtle squeeze

 

keep our eyes on that huh...

I will pop a couple of these out to allow for losses, breakages and breakdowns.

Big blue box here for me too, Bill...

OK I found that one had gone rogue when I just popped back for a look

 

Reloaded now

 

This one

OK ish, must be time to test postimg again

 

Can we study this extract from an AP which might just work for Belvedere engineering in service

 

P1010698.jpg

 

I remember Crisp being somewhat perplexed by its operational efficiency

 

Ish

 

The rubber/steel damper in the centre screen would be replaced by a hydraulic drag link damper in a Sikorsky/ Westland helicopter I believe

 

That would probably allow the advancing/retiring blades a bit more flexibility than the rubber block's relative inflexibility

P1010699.jpg

 

Oh well it seemed to work OK for the times they were in service

 

And we are not here to worry about them

 

I have a bigger problem

 

Can you see the arching frame over the hub which controls pitch on the blades

P1010703.jpg

 

No?

 

Me neither, something must be done.

 

I know chop out everything that isnt the arched selector.

 

Then arch a selector over the gubbinses and add a new upper frame

 

Here a couple of the arms are done in the jig

P1010704.jpg

 

The white block is the jig of course and at the front of picture is the rear blade rotor head which has its rotation in the opposite direction

 

The rather thick cross bars are supposed to the the arch pieces

 

To be honest I prefer mine

When the glue has set I intend thickening the frames with Mr Dissolved Putty to get a more reasonable likeness.

 

Time to sort out the blades next.

Hope it looks better now, thin smidgen of Mr Dissolved P over the arms which seem to be finely forged things of elegance on the rotor head.

 

Maybe not quite as elegant but...

This seems OK so I will get on with the rear gear.

Ta Ced.

 

Just for a minute can we catch a flight of fantasy.

 

Here we are with all the paint on and the windoors open and the rotors fixed.

P1010711.jpg

 

well it is only a fantasy for now, come back next... Month... Year... Decade... Cen... no not even I can spin this out that long.  :)

 

When the paint is on the window openings are going to be carved open in the sides and the front and ceiling panels will be demasked.

 

Hopefully this will look OK.

 

Belvedere has very thick window openings, far closer to stone mullions than modern thin metal glazing framing.

 

I think  that is why they look almost prehistoric purrups.

 

I have removed the unwanted plastic moulding from the plunge moulded wind deflectors and trimmed the glazed bubbles to fit.

 

Added the part finished rotor head and asked your indulgence.

 

Work for you?

I think I have  the basic idea how this differs from the Sikorsky/Westland style rotor head gear

P1010698.jpg

 

Any idea about the pseudo-Slan type tendrils rising above the nest of gubbinses

 

Is it telepathy?

 

Might be amusing to replicate.

 

Might...

My guess is mass balance weights to smooth out changes in blade pitch. But then, that just popped into my head. So it could be telepathy.

Other theories are available.

I think you have the right of it Pete.

 

Is it a good idea to get THIS interested

P1010712.jpg

 

I mean...

P1010713.jpg

 

Probably just nosy.

 

Probably but having access to AP4672F is very enlightening...

 

How much could one improve the Airfix offering if such knowledge was here?

 

 

 

Just wondering.

Oh oh, looks as if someone removed the centre spindle and the upper extension (totally wrong) of the rotor shaft extension then drilled out the excess plastic with a 1.6mm drill.

 

Ohhh!

 

P1010715.jpg

 

And took away the brute thug spider arms that would not lift a rotor blade for all the viruses in China.

 

Must be going to make a new shaft, base to apex but whether that was a good idea or no, I am still undecided.

 

Ah it would appear not to matter now

 

P1010717.jpg

 

 

The new spider arms are to come tomorrow.

 

I really do NOT expect to make any more rotor head changes, but tomorrow is another day...
