Good skills Ced.

Only warm the plastic for a few seconds, I watch for the deforming signs of rippling a bit, not the complete softened 'come and get me' of the ready to cook film.

We only need warmed up a little

 

I’m with Bill on this Ced.  He knows a thing or two does Bill - but don’t tell him I said so ;)

 

I try to heat the PETg as far from from the heating element as commensurate with it actually heating up! And then try to heat it to the minimum necessary.  I think a few failures on the way to success are simply inevitable.  For a klutz like me anyways :)

Hmmmm. 7 days and 5 pages late. Must be a personal best! Dunno how I missed the start Ced and I've only managed to get to the end of page 2 & my eyes are closing (nothing to do with your modelling!!) so I'll play catch up in the morning!

Listen very carefully, I shall say this only...   ' til you get the method

 

PETg

 

I only use the thinner stuff anyway and remember you need to fit it into a specific place on the model.

 

Thick might not be your friend.

 

Only warm the plastic for a few seconds, I watch for the deforming signs of rippling a bit, not the complete softened 'come and get me' of the ready to cook film.

Then a slight pause

 

Then let technology and art rip

 

As some guy in that very useful link says it is an artform.

 

Practice makes    canopies.

Warm up, pause, SLAM - got it, thanks Bill :) 

Art? I don't know much about art but I know what I like…

Clear canopies!

Be careful what you do in the bath?

 

I'll have my fingers crossed for you.

Just adding my :2c: to the  valuable advice you've already received: I use a thinner plastic, 0.3 or 0.4, I don't have it at hand now. I try to heat it up very gently, to the point when it starts  going wavy. But on top of that, the stuff I use is very clear in its flat state; a bath in Aqua Gloss once vacformed is also recommended, to sort all the minor blemishes. HTH

 

Ciao 

Thanks Giorgio :)

Wavy, gentle, SLAM! Got it.

They're looking much better Ced.

 

That said, given that my experience of vac-forming is extremely limited, I have taken to sitting behind Bill in the classroom, peeking over his shoulder and copying everything he writes. So do everything Bill says... except the bit about putting your life savings on that 200/1 outsider at Newmarket.

Thanks Tomo - me too, learn from the Masters I say :)

Far away, minimum heat, SLAM! Got it.

Ced, PETG is hygroscopic, which means it will actively absorb moisture from the air. 

You could try drying it in the oven first, maybe an hour or two around 60 - 80C?

 

Thanks hendie - good to know.

IF I ever use the thicker 0.7mm stuff I think I'll have to do that :)

Hi Keith - nice to see you.

Have a nap, always works for me… oh, wait, late night eh? Sleep well matey :) 

 

 

Good morning this morning, eventually.

First an apology to the PETg suppliers. There ARE two protective sheets, but one is clear:

 

50712760193_ceba9efe45_z.jpg

 

I noticed that when it peeled off of one of the failed pulls:

 

50713597432_0c0f58e461_z.jpg

 

The one back left I think, it certainly looks shinier.

Both of those were me badly estimating what' warm' means but I got it right in the end.

 

The Plasticine didn't work by the way. It melted:

 

50713522006_683f8c3b31_z.jpg

 

… so, to overcome the 'lip grip' I cut the base into quarters with my newly inherited snips, cut around the top of the lip and pulled the sections away:

 

50713606667_d49bbdd1a6_z.jpg

 

Eventually, with some very gentle prising over the windows, it was off.

I am a happy bunny:

 

50713542426_3df03ea320_n.jpg 50713544521_2a31517125_n.jpg

 

50713543161_c3a5939450_z.jpg

 

Safely stored away - it's the one with the tape on:

 

50712808608_71d7ee0315_z.jpg

 

 

Now, next nasty, the grills:

 

50713629432_e60aed4f5d_z.jpg

 

Seven at the back but how many at the front?

Nine? That's good because I can start in the middle.

Hard to find a good reference shot.

Thanks Bill, Giorgio, hendie and Pete :) 

I think I've got the hang of it now. Of course I'll have forgotten it all next time I need to vac form :( 

The canopy will be cleaned, polished and dipped once I've cut it to fit, later.

 

This afternoon I started the grills.

But wait, what's that big hole in front of the lump on the top of the fuselage?

My reference shots and Bill's build show that there's a… lump just inside.

Rats, I wished I'd noticed that before close up.

Nothing for it but to splodge some filler in there and shape the inside with the end of a suitably sized drill bit:

 

50714597807_3ea9f6aba2_z.jpg

 

First lump of filler in. You'll see more in later pics. Maybe.

 

Grill one done:

 

50714759986_225cb5b3d0_z.jpg

 

You can see, just in front of the blade, that I've cut a few more vanes.

All I need now is the patience, and steady hands, to glue them in.

 

What about this though?

 

50714860102_4f1cd34786_z.jpg

 

I did think about drilling the windows and using clear stuff to fill. Maybe.

BUT it should be level in the middle with no ejector mark eh?

With no massive gaps.

Later.

Thanks Tomo :)

I think that's one of the pics Bill posted earlier but a helpful reminder. It looks like two separate window surrounds eh?

 

After sanding the bottom (titter) this is better:

 

50717777348_0946328395_z.jpg

 

…but I think I need to 'separate' the surrounds a bit more. Hmmm.

 

I did manage to fill 'the hole' and get another couple of vanes in:

 

50718805656_aabff8d20f_z.jpg

 

All I need to do now (a ha ha ha) is fill in the gaps with four more.

Gulp.

 

Lousy weather here today so I got the S.A.D. lamp out:

 

50718807506_7fea10a564_z.jpg

 

Crikey, it's bright.

I've had it for some years but keep forgetting to use it. According to the Lumie people, 20 minutes 'light in your eyes' "is proven to improve energy, put you in a better mood and make you feel more awake."

We shall see!

Those not windows underfoot Ced they are lamps, probably landing, early Belvedere for the use of.

Not seen on general service machines. The inlet on the back of the fuselage upper works just in front of the tail fin pylon thingy is an oil cooler which sits back in the dark of the tunnel slightly. I think you could just put something down the hole just to block it up. At the front is an impeller fan.

 

If I was as clever as our friend from the helo-museum I could send you lots of AP pictures to confuse yourself with what's going on in there do you want me to try to work it all out?

 

Yours is looking fine, makes me wonder...

 

Get another?

For silver and white?

 

Nah I have you and Tom busy making the rest of a tiny Belvedere fleet after all.

Mighty progress there dear boy! 🏋️♀️
Everyone seems to know so much about moulding plastic, I’m feeling rather left out. Your work on the subject is exemplary. 🧐 Why on earth they decided to glue it up the middle is beyond me. 😱

Those vanes too. Very neat. 🤗 As for the S.A.D lamp. I bought Gemma one about ten years ago as she hates the dark mornings. She was a grumpy sausage in those days. This made her loads better in the mornings.  I can highly recommend. 🌞 Happy wife and all that. 😉

 

Please sir can we have some more. 😀

Now separated with a scriber and microsaw:

Chiselled and filled:

Needs a clean up but better?

Thanks Johnny, very kind :)

I would give moulding a try - good fun and you get to play with chemicals and Lego!

 

Pleased to hear that the SAD lamps work.

 

Some more? Well, I fitted one in the front:

 

50721096607_ee48a38364_z.jpg

 

But then decided there are ten vanes.

10mm gap to fill.

That's NOT one every 1mm is it.

I hated those school questions like 'how many posts to you need to make a 10' fence with the posts 1' apart?'

Still can't do it :(

You'll need nine vanes to fill a 10mm gap at 1mm spacings, the sides of the gap count as the outside ones. The fence answer is 11, 'cause that does need to include the outside ones. 

Nice progress Ced. :)

Steve.

Thanks Steve - great stuff! :) 

I need 10 'posts' though in the gap…

Still too hard for me - I get a brain freeze about it - so I resorted to (software) tools, as usual. See below

Coming together now Ced. Superb result with the nose glazing

Thanks Roger :) 

 

 

So doing it 'by eye' won't work. Although I can roughly gauge a gap, I can't spread 10 vanes at the same time and I'm worried I'll get to the edges and think 'Rats, the last ones don't fit.

How about 'physical modelling':

 

50721292553_5650072d67_z.jpg

 

That doesn't work either.

These things are tiny.

A sense of perspective:

 

50721293158_16db9b130c_z.jpg

 

See?

Bottom middle.

There may be 10 vanes there still, although I may have brushed / sneezed / got one stuck on my hand, again.

 

Silhouette Studio I can cope with:

 

50722061926_fbccb79fdb_z.jpg

 

Right hole, vanes correct 0.2mm thickness. Gap measured at 0.6mm.

Now I have the numbers, how do I implement them (as the mathematician said to the actress. Never)

 

Aha!

 

50722069546_3fb06acb05_z.jpg

 

First one stuck in the middle:

 

50721334833_b3a1a04e13_z.jpg

 

Now I just need to wait for steady hands.

I may be some time…

 

I've also been thinking about masking the nose.

Giorgio will be pleased to see this:

I used fine wire, straightened for my vanes

P1010661.jpg

 

And this shows the coupled gearbox oil cooler intake.

 

Complex innit.

 

P1010686.jpg

 

Luckily because the Productiovedere has an oil cooler in front of the front rotor gearbox I only needed two each side, dodged a speeding bullet there.

 

:)

 

Looking fab Ced 👍

Ah but it all depends on needs. I only mold if I have to as although it can be very satisfying it can also be extremely frustrating.

I've been using your build as a reference, of course, with the bar lowered so that I can reach it.

I saw the wire but a ) I don't have any like that and b ) I'm happier with plastic and c ) I thought the wire would be even fiddlier!

True Mark, true.

I had a period of molding pilots and may need another session - sometimes it's the only way.

You're right though - pulling a nasty result from the mould is as frustrating as pulling a nice one is rewarding (fnaar!)

 

 

'tis done:

 

50722627997_89f8f77a99_z.jpg

 

But wait, what's this:

 

50722628402_1f6ce1a537_z.jpg

 

Two spare vanes?

After all that measuring what could possibly have gone wrong?

Plans, that's what.

Best laid and all that.

Punch in the mouth too (Mike Tyson quote)

 

So, the answer? Steve has it:

 

dbd11c5113c0b07ca3980d04a2a47d14.png

 

You're not counting, are you?

 

Desperate for something simple for relaxation I looked at the instructions.

Tailplane next.

This tab isn't going to fit is it?

 

50722563456_1c8cee1a34_z.jpg

 

Slice the slot and dry fit.

Up a bit.

Back a bit.

The Lego was brought out to form a jig:

 

50721846353_85f9998f37_z.jpg

 

… but I don't have enough hands, so it was time to 'trust the Airfix struts':

 

50721853208_067d868e5e_z.jpg

 

Look OK?

I still have the hammer…

 

Of course I could have left those off to make painting easier, but where's the fun in that?
