I know with the laser radar it gave us a point cloud, which then needed a lot of post-processing to get CAD surfaces. I guess things have moved on a bit in the past 4 years or so - I'm not really into that side of things now.

I think I saw in Hornby magazine a while ago that some model locomotives (diesels) have been moulded from scan data. Not sure if Hornby themselves do it though.
The biggest problem seems to be the sheer volume of information generated. I only do bits of cars, but the file sizes are enormous! I guess for something like a plane you wouldn't need the data to be so dense, but I suspect it'd still need a lot of post-processing.

Having said that, you wouldn't need to scan it with a laser to get the basic geometry. You could 'hard' probe the important bits which would give you more envelope type data, but a very good starting point smile

Flaps!

Ahem. Seems to be a fairly rare Eduard etch set these days. Got it off EBay all the way from California believe it or not.

Not strictlyvon topic but relevant to the dicussion in some ways - these people laser scanned four of our locomotives (I work for the Ffestiniog & Welsh Highland Railways). They're making laser printed models of them:

Thanks, I'll have a read of that tomorrow at work.

Made a bit of progress this evening - bent and glued the flap stiffeners in place. Clever way of doing this from Eduard - the tiny fillets remain attached to the main surface when you cut them from the frames. There is just enough material to pivot the fillets around and into place, so avoiding having to pick tiny individual parts up with tweezers:



The flap parts now need a 0.6 dia plastic rod attaching to their rear edges, before brushing with a fibre glass pencil to remove any excess glue, and priming. Then it's more wing scraping to get them to fit. There won't be much left of the original wings at this rate.

It must be near the point where it is worth the resin trans-kit boyos offering entire wing sections. Their casting work is obviously up to it, detail wise.

Nice touch from Eduard as well on the flaps.

Yeah. I alluded to this on BM on this subject: At what point does it stop being 'modelling' and start to become "painting"?

Someone said they were surprised at how much detail I was cramming in at such a small scale, but really all the detail is cast into the resin, it's just a matter of fitting the resin and painting it.

Just in the process of un-glueing the flap stiffeners because I forgot to bend the inner wall up through 90 degrees first.

RTFM dr_gn.

Dismantled wing inserts:


Bent and re-assembled correctly, plus - obviously - more wing thinning. Also drilled out the flap indicator apertures:

All went a bit meh recently - I had to sand the wings so much that I removed some of the wheel well roof detail. Tried to save it by adding filler, but it looked terrible. Ended up making false wheel well roofs with plasticard and building up the stiffener detail with plastic strip (which is a bit too thick now).

It'll be OK, but one of those diversions that's a bit demoralising to deal with. Anyway, glued the flap wells to the wings and also put the p/e lock eyes on the u/c legs:

Thinner plasticard in the wheel well roof, maybe




OK Only kidding, this has been a great lesson in using PE materials for those like me, just a bit wary thumbup


Keep up the good work dr_gn

Yeah, but then it melts/distorts when you glue it! I wanted some very thin glue (ie not PVA) to capilary under the whole framework to seal it. I don't trust Klear for this, so I was left with liquid poly. It'll be OK.

Yeah, could try that. Might have another go tonight. With CA I'd have to glue the thin strips to the wheel well roof first, then trim it to fit.

Best CA out there I think. Used to get all over me though as it was so thin it would run down the grain of the wood and out the other end, it was like the balsa was a tube!

All sorted now - I rebuilt them again on the bench using plastic card an liquid poly, then trimmed them to fit over the u/c bays.

The Spit very rarely had the flaps down when parked.

Still top work as always & in that scale they must have been fiddly as hell, my hands aren't still enough to contemplate such effort. Seriously good work smile
