Earlier today I found out that you can print copper! Where will it all end?

As a materials chemist working on some ideas for the field I can say you'd be amazed at some of the stuff that is in prospect. There's even lots of work on printing directly with calcium phosphate pigmented resins that you can print, heat sinter to burn off the resin and then use as surgical implants where the now mineral phosphate straight away gets incorporated into new bone growth. Not weight bearing strength straight away but long term being able to get bone to regrow in the shape of lost material is a great idea for post-accident or disease reconstruction

Nice to see the booms getting the join the dots treatment.

They're not going down without a fight James! Initial thoughts about 'a day'll see them done' soon flew out the window - they're almost like trying to design a set of small fuselages in their own right with all those curves and profiles around the wing!

Fascinating Alistair. :thumbsup2:

I try and keep abreastof such things in New Scientist as much as possible but a far as materials science goes there are some truly alchemical things happening nowadays that continually astound. I'm reminded of that old Arthur C. Clarke saw about 'any sufficiently advanced civilization will seem like magic...'

As mentioned in the opener, these booms are a right handful for a number of reasons. Not only are they asymmetric top and bottom in terms of their forward extents but addded into the mix is the manner in which they split over/under the wing camber. No question in this instance of being able to build a single elliptical run and join it into the wing as a single unit, however one small mercy has been having an X-ray in the form of the station diagram to help decide how to break the frames down into manageable sections:

49931576082_85b340f0b0_c.jpg

The hardest part was establishing the plan outline of the booms on the upper and lower wing surfaces. With these a series of undulating three-dimensional curves no easy task but eventually with the aid of some surface projection I was able to get these established and then begin elaborating a framework around them:

Uncannily like a Toucan going for a Guinness....

49930753253_4ee4e2aff2_b.jpg

See what I mean about all them curves? Brings us back to @71challys earlier remarks about the sheer skill of the guys who did this the first time round.

Added into the mix for some comparison shots:

49931264436_7952f8efab_b.jpg

49931264446_8f518203e0_b.jpg

All very picturesque an' all that but the make-or-break is always the comparison with references:

49930753293_ba23df2203_b.jpg

Reckon I can live with that.

 

That port wing's dropping again - where's @Neil Lambess? :laugh:

Utra-windy for the time of year here since Friday with a number of trees in full leaf getting blown over, however this evening turnedto a May heat bath that has the garden awash with perfumes of Musk rose, wisteria and clematis at the back door:

Son and his missus brought our grandaughter over for a visit this afternoon, 'social distancing' having the missus and me hanging out of the lounge window and Eden running around the front lawn doing animal impersinations. One was obviously a bird - 'parrot' says I, 'Eagle' says Nana. Nope. Sparrow? No, Crow? No. Penquin? No. 'Give up' asks Eden? Yes we chorus. 'It's a Toucan silly'!! Instantly into my head comes - ''Guiness for Nigel, Guiness for Nigel''.....!! If only my brain would retain useful stuff as it does advertising trivia....!! 🤣

Great work Tony the renderings are providing us with more Sea Vixen lovelyness.  

I have been getting the mancave liveable and creating my new workbench from our old computer cupboard along with populating my shelves with my models and got out my Sea Vixen FAW.1 and had a long look around and realised what a great job you are doing here with your wonderful creation.

Great work fella.

All the best

Chris

Superb.  And we’ve had references to Farnborough & The Fleet Air Arm (a fascinating book) AND 801 Live (a true classic; I have a copy signed by Phil Manzanera, no less).

 

Marvelous!

Did you know that David Byrne was a huge fan of the Fleet Air Arm too?

Took Monday morning off as to be frank sometimes you just have to prioritize matters and we're so close to completing the broad outline of the Vixen and I'm gagging to put it on fer a test print.

 

After some particularly strong tea I was able to pare the final boom/fin/rudder assembly down to an economical set of drawings that can be further adjusted in response to any flaws the printing shows up later:

49933929768_73921eb1f2_b.jpg

Again the station diagram was a great resource in working out how to get from the boom joint (purple ellipse) up to that great curved shoulder defining the top of the fin in the fewest number of steps. As an aside - the width of my boom joint here (which I'm pretty sure is accurate for this scale) at 3.5mm in horizontal diameter is substantially different from the rather fat 5mm that SH have theirs at when I measured the kit.

 

Turned into a solid boby and mated with the boom:

49934444141_80f45cc115_b.jpg

As mentioned previously, the bumpers, rudders &etc. will get represented in the next detailing pass, the priority here is to block out the main outlines as accurately as possible:

49934748757_01cec23780_b.jpg

49934748792_bf9759f08e_b.jpg

Again, these might look ok in isolation but always necessary to offer up to the main assembly to be convinced.

One absolute godsend that has improved my critical abilities at this stage of checking the aircraft is one of these babies from 3D Connexion:

49934561356_60788ed3dc_c.jpg

That's effectively a mutli-axis controller that let's you smoothly move, rotate or zoom into the aircraft smoothly in any direction you want - the virtual equivalent on screen of being able to hold the aircframe in your hand and move it around in the light as fast or as slow as you want (and in ways impossible to control with a traditional mouse). These 3d mice aren't cheap but I'd been lurking online for several weeks until a refurbished model popped up for a reasonable outlay of gelt.. It's been an indispensible part of the workflow for the last month now and improsved my ability to check for flaws/errors no end (and let's face it, there are a lot them).

 

That banking-away oblique view of the Vixen you see so frequently in airshow photography that shows off the booms/fins in elongated profile:

49934444101_73c1d26472_b.jpg

And a final render to check the contours for continuity:

Those funny little half-cone things and the brigdging plank of the elevator to go in between the fins next:

lovely work Tony.  You must be nearly 25% of the way there now.  

I tried one of those mice but never could get on with it though a few folk at work have them and claim they're indispensable.  I do so little CAD work these days that I'm just going to potter on in my antiquated ways.

 

So which bit(s) are you going to print then?

Thanks G. It's such a delectable airframe when you spend time with it -- so much imagination went in to sending two souls hurtling through the sea air.

Glad you approve! :thumbsup2: I had eyed the more elaborate version of course but even my weak morals couldn't justify the outlay. :laugh:

The funny thing is that even when I'm not doing any CAD work I'm still reaching out to for it to rotate what's on the screen. Makes no sense in MS Word!

Ok. No blather today.

Finally got the tailplane done and that means that all the coloured regions  in January's diagram  are now completed:

49460485413_ecb210b00d_c.jpg

A simple enough drrawing job to finish-off on (once I'd established distances and angles with boom):

49938104346_04c6ceb0a7_b.jpg

Lofted into solids and then the boom conoturs carved out of the edges on either side to enable fixing to the uprights:

Plan view of the whole shebang:

49938407282_f6494e225f_b.jpg

I'll post the next series of images without comment - a series of perspective views to eyeball apppearances from all angles:

Not going to be able to put this on to print tonight as I need to hollow out the various airframe sections prior to getting them oriented in Chitubox and all the supports added for printing, which will take a few hours.  After that I'm guessing about 10-11 hrs to print the lot and then a complicated clean and cure session on the resin afterwards.

 

I've meetings online all tomorrow morning and have to drive down to work after lunch (first time in the building since the lockdown started here on March 13th, which will be strange to say the least) in order to collect a rake of camera gear and lenses so I reckon it'll be Thursday earliest before I can get near to playing with the supports and stuff. All being well then I'll get this on overnight Thurs and hopefully have some positive physical results to share with you some time on Friday.

 

FAB

ATB til then.

:bye:
