Building TN Halifax

[rookie jim]

Hello to everyone building the halifax. As you know i opted out of this one but always keep an eye on this forum.

 

I must say you are all doing an excellent job. As i read the various postings I have mixed feelings. I envy all you that are doing it but at the same time I am relieved i  am not doing it as i know that  i havent the skill ( hopefully its only yet)  to build such a large model to your standards .

 

all the best with your builds

John.

 

That is a very nice simple little jig

[Craig Carr]

Hi John,

 

Yep very neat indeed.  I made a jig for my pillar drill to do the same operation, but yours is a much neater and simpler solution.

 

Welcome aboard by the way.  Im sure Mario and the others will be along soon to say hi.  Have you got any other pics or is the tail your starting point?

hi John,

 

the jig is a great idea. I think a similar jig would be helpfull for ailerons too.

[Terry Whiting 1]

Michel,

 

I'm not trying to be facetious when I say, It takes a brave man to build in any

machanics (servos), but a wise man not too.

 

You have made a nice job mounting  the aileron servo, but the method of

"building in"  I would not recommend. That linkage is almost identical

on my Mosquito, but the servo was mounted on a removable hatch.

 

If any servo is going to fail, it will bound to be one which is built in. (non serviceable)

Terry,

 

well I know what you mean, but while thinking about this, I never had a servo failure (always used hitec MG servos or equivalent) for my 10-15 years modelling on more than 30 different airplanes. Usually if the servo should fail it will happen at the first minut of use. Well this is my experience and if something has to happen... you can always make some "surgery" to remove the servo. I tought initially  to make a solution like you said but I just it would be more work and I am bit lazy sometimes  .

 

Another point is that if you have an aileron servo fail on this kind of airplane wich of course would happen in flight, chances are that the entire plane will have to be rebuilt after crash (if not too damaged) anyways and the servo lock will then be the last point to wich your attention will focus.

Michel,

 

I take your point,  ,   but as for laziness it's hard to believe you ever suffer from

that complaint , you building is immaculate.

Retracts arrived today from unitracts

 

 

[aerts michel]

Thanks Terry.

 

Hi Andy these retracts looks cool.

 

Is it air up air down kind or air up / spring down? Does the kit includes air container too?

 

 

[Danny Fenton]

Hope you don't mind me joining in, But I have a couple of sets of Unitracts. If you look carefully at the area where the Piston meets the body of the retract you wil see a small brass tube, this is one of the air up air down feeds. the other connection is the white nylon nipple on the end of the piston. Tony ships a clear plastic bottle as the reservoir tank. Good for 80 - 100 psi.

The oleos are really nice, sprung but damped utilising a special grease, really nice

Cheers

Danny

They are air up air down, & have a speed control screw build into the cylinder, they do not supply air containers, a plastic bottle used for fizzy drinks can be used as long as it has PET stamped on it, they supply a bottle top for this purpose (the white top in the photo), I haven’t decided what to use yet as an aluminium air tank is not to expensive but will be slightly heavier.

 

[Ian Whittaker]

My retracts have arrived today as well. The engineering in them is rather neat! I'm impressed!

Hi John

Welcome aboard

As more guys enter in this thread more are the chances to all to achieve our goal.

And if someone of us take a new building idea there always the chance that the idea is better

than our own and in a simple way we help eachother.

Using jigs like you do is always half way to do a very clean and precise work.

Now I'm building the fuselage sides that are quite a work because the balsa sheets came in badly, and I order from SLEC a fuselage jig that I need to mount.

Soon I will post some oictures of the progress.

Regards to you all

Mário

Danny we don't mind at all, we thank you for your help.

Craig,

I started with the tailplane to ease myself into the winter building programme - recently finished a 1/4 scale Nieuport so taking thisslowly.

Mario,

I too thought about using a fuselage jig after seeing Andy Wood's blog so bought some wood offcuts, got the table saw out and made one - fully adjustable for future projectsand should have made this 40 years ago.

[aerts michel]

Hi John, this is  what we can call a big size jig.

 

For information I just ordered the unitracts retracts today and delivery date is november now.

Hi guys

The building continues, not so fast as I would like because the weekends

are all for flying until the good wheather is here.

Just build the jig from SLEC and I'm not very satisfied because the

squares are a little flexible, should be more rigid, but I think the problem is the

plane is to big for this jig.

 

I decided to copy the plan and glue under the fuse sides for helping me to know the correct place of the parts, and then glue the ply reinforcements and the bomb doors stringers.

 

Following Toni N sequence  building I glues the F5 and F& formers.

 

And then F4 and F7

 

Ready for the jig working

 

The other formers and the nose shape appearing

N ote that I made some holes at the F1 to permit to separate the vacuum nose

and have acess to  bateries place

 

Now is time to place the top basa stingers and triangle bars to finish the top

of the fuse.

 

 

The building goes on

Regards

Mário

Hi Andy

Look here

http://www.modelflying.co.uk/forums/postings.asp?th=26174

Bjorn make a good work with landing lights in is Lancaster

and I think they are of the same type of the Halifax

About put a YouTube video, you open at the same time this thread and the You tube page

Visualize the thread and click the  YouTube Icon when you post a reply

Open the You Tube page and then copy the embebed code from the video, change to thread  and paste in the yellow window up. That way must function.

 

[Andy Wood 1]

Thanks Mario

 

I have been following at the lancaster thread,but the halifax only had 1 landing light unit

[Ian Whittaker]

from Mario's post -

'N ote that I made some holes at the F1 to permit to separate the vacuum nose

and have acess to  bateries place'.

An excellent idea! Thankyou. 

[Supermario]

Hi Ian

You're welcome.

Andy

Your Halifax landing light is faboulous. Congratulations for the excelent job.

Can you show the mechanism you use for that?

Regards

Mário

[Andy Wood 1]

Hi Mario

 

Here is the workings, tried to keep it as simple as possible, I will add the LEDs etc after paint

 

 also

 

Im with Ian, making the nose removable is a great idea

 

Andy

[Alan Shears]

Hi  all

           Has anyone built or building the nacelles at this stage, i am finding it a bit difficult to work out the plan.  Would be gratefull for some pictures.  That is the inner nacelle.

  Regards Alan

[Andy Wood 1]

Hi Alan

 

I have had just the same problem, but I think I might have got my head round it now, I just need to add some bits to the inner nacelle & then get some pictures uploaded that should make it clear, the plans are not too clear & i think they could do with a 3D sketch as with the wing joint, hopefully a photo will do just that, I should be able to upload it later tonight.

 

Andy

[Supermario]

Hi Alan

I was reading your post when Andy came in help, but I tell that

I haven't yet start the nacelles but when I was separating the formers

I realise that building it was a kind of dificult.

Then, after some hours thinking I became to conclusion that the

better way is to build a jig just for that.

If you want I can post a draw with the jig I intend to make to build the nacelles

Regards

Mário
