I noticed too that there is a second set (outboard of the engines) of those Howler's Besotted Flaps that James gleefully described yesterday, that will also need be-slotting....

At least you won't have to do what @CJP has had to do with his Alize' flaps!

If Tony could find some that were reallllllllly strong Giorgio, do you think he could fix them so that they repelled each other - he could make a real 'Flying' Boxcar then, with no visible means of support.....!! :D

hate to see the magnets stronger than the plastic bond

Don't worry Ian - the trick with neodymiums is to gently slide sideways to break the strength of bond, rather than a manly heft upwards. There'll a thin layer of something soft on the metal plate as well so that this won't scratch the paint.

Confession!

Forgive me Fr. Martian for it has been three weeks since my last confession. I have fallen from the path of righteousness and repeatedly coveted kits and tools.

Here  - I posted this article I discovered about Martian aviation earlier that you might recognize old friends from:

My guess is that it would end in tears using just magnets on a pole-based mounting as the aircraft would just skate sideways due to the fine tolerances of balance required. Something might be possible using an electromagentic field however, like maglev trains....

 

Giorgio - anything like that where you work? :whistle:

 

Good evening chaps. Just a little curtain-raiser for you this evening as we need to cut some more bits off of the kit:

27806142638_277fd39574_c.jpg

Since James's information about the Fowler flaps I've spend the last couple of evenings squinting at the relevant sections of the maintenance manual in order to more fully understand the various control surfaces.

 

You can see here that each wing has both inboard and outboard ailerons, and the same arrangement for the flaps:

40964964084_cca4036666_c.jpg

From the top those shapes look a relatively simple job to cut around for removal, but the same can't be said of the tailplane I'm afraid:

40784474095_af5868d9ff_c.jpg

I'm sure that there are sound engineering principles behind that irregular shape, but to my untutored eye it looks quite like something Charles Rennie Mackintosh might have had a hand in. My one consolation is that I haven't yet found a shape that couldn't be cut out with the right methodology but at the present I am eyeing that region warily as a potential Nemesis....

 

My faith in using larger heavier tools in a delicate fashion was renewed here by ditching all the fancy countour saws and fine blades I originally gathered together, instead just gently scoring these outlines with a Stanley knife until you see the white stress line appear along the reverse side. At that point it's safe enough to bend the kit plastic until it shears off:

27806142448_c09ce65c75_c.jpg

Resulting in nice sharp, neat edges.

You can see the lovely job Italeri actually did of the moulded detail for the underside of the outboard flap, but the various hinges for both ailerons are a stumbling block:

40964963954_fc7e17cdbf_c.jpg

You could conceivably spend ages scoring around those aileron-hinges but I preferred to apply Bill of Occam's Stanley knife to remove the whole assembly, cutting out the slots and adding new hinges to the wing later:

40784474185_0e4a4a44fe_c.jpg

That's one wing done, only the other one to do, the inner flaps, tailplane, rudders......:frantic:

 

Note to self that I need also to compare the panel lines on the wings to those shown in the maintenance manual.

 

After a day of teeming rain and sodden overcast here I look outside to see the that sun has come out just as it's setting. Don't you just hate it when the universe does ironic. 

:bye:

Tony

The elevator. It depends where the hinge line is. It may be on the second line from the front. 

So that would mean there are weights along the leading edge to balance it. 

That way the airflow helps to deflect the elevator (If I remember non powered control surfaces theory correctly).

Also, I suspect the rudders impinge onto the tailplane surface which would explain those diagonal lines.

Of course that could all be garbage. An expert will be along shortly.

Sorry to barge in here Tony.

Neodymium magnets are a very fine piece of kit, low mass and high magnetic output means they are ideal for head-phones/ear-phones.

A friend of mine (a bass player) has a speaker cab with one of these magnets in, you can pick it up with one finger instead of a forklift.

 

BTW Magnetic Fields was a fine album by Jean-Michel Jarre.

 

Great work on the flaps Tony.

More surgery ahead.

 

Simon.

Hi Tony 

 

Would the chain drilling offer a solution or cut off the whole thing and build up the awkward ends again on the tail plane. 

 

I'll get my coat 

 

All the best

I use the same technique you used for the ailerons, it works very well. I'd be tempted to do the same with the elevator. IE cut it all off and replace the ends with plastic stock.

Hello Tony,

Variations of green ?? Look this one has not been restored.

The seats has been changed but that old bird has also saw my father jumpin'out at the end of the '50s

The tonality is also marked. Sorry for my daughter and her snake.

What a really great job you did ! I stay in awe !

Congratulations !!

Sincerely!

Since when were you ever on the path of righteousness? If you went to confession it would blow the parish's overtime budget for a whole year. Anyway I'm Church of Mars, so there!

Hi Tony. Just spent an intense week reading your entire build, all 84 pages! 

You've done some stunning work on this kit, makes me want to break out the gunship variant I have. 

On a slightly sad note I was sorry to hear of your bereavements over the last year, please accept my deepest condolences, and was sorry I couldn't offer them at the relevant time. 

Keep up the Stirling work. 

 

Matt

Thanks Giorgio. The first one is always the hardest isn't it but having got a 'feel' for the plastic with the knife now, it's just a matter of patience when attacking the rest of the subassemblies.

I couldn't see any parts listed for the weights but reckon your surmise about the angled profile due to intersection of elevator and rudder a likely cause - once I've cut those bits off we can tape them together at an angle and test the theory...

I'm no doubt channelling your superb Battle-surgery here Ian - this method seems to offer a premium of control over sawing away as I've done in the past - with the attendant uneven lines...

Not always weighted mind, sometimes it's an aerodynamic balance whereby the nose of the surface is ahead of the hinge point and  moves below and above the main tailplane surface.

The angled cut outs each side look to be to clear the rudder deflections.

 

Lovely cuts mind!
