In high gloss, the 47xx bathing in sunlight, and awaiting lining out.



I also cleaned back the cylinders and will paint them high gloss with the hairy stick so they can be freshly lined too. The chassis and motion will need some clean up too, but that's not so critical to getting it to a runable state.

Cheers,
Alan

A 3 hour decal session has seen the decals completed here, and the loco has somewhat unified its look.

Still need to do the cylinders, and clean up the original numberplates to refit them

47xx has regained her (original) identity. Also added the WR red spot marks and painted the rear bufferbeam.



Bodies now complete ready for final varnish. Chassis still needs a little more work.

Cheers
Alan

While the final satin varnish is drying on the 47xx, progress made on some others.

3rd pass of primer and smoothing on the V1 has highlighted the one utterly frustrating thing about 3D prints - the layering clean up. Even after seemingly hours of sanding, primer, sanding, primer, there's still layering visible. The material is definitely not amenable to sanding - it just does not sand anywhere nearly as quickly as other materials, meaning you think you've done loads, and find it looking virtually no different after priming.



From the projects box, one from way back on page 18 of this thread has been unearthed - a Fowler 4P 2-6-4T (interesting comparison to the V1). This is on a 3MT chassis and I've made a fair bit of progress in the last few days with more of the detail, getting the chassis to sit correctly, meaning hopefully this can reach the paint shop at a similar time to the V1 above.





Still some to do including the smokebox door, fitting the cab roof, and front lamp irons and coupling hooks and a whistle.

Cheers,
Alan

Final varnish coat done on the 47xx, and the result has been very pleasing.

Now I need to fix the fitment of the tender top (it doesn't really sit down right), and fit more weight, change the tyres to improve the running.

Alan

I know I always wait for the satin varnish pics, but that's a lovely loco, Alan :drool:

Yep fantastic work Dr Al', utilising what was available and plenty of ingenuity. I really admire this sort of modelling.

I realise I didn't put a before/after:

Before:


After:


I think the vast essence of the original model remains - the changed components were the loco wheels, the tender top (albeit the same as the original), the chimney and the buffers.

Cheers,
Alan

Dr Al',
         What brands of filler and satin varnish do you use please?

I've used various fillers in the past, though try to absolutely minimise its use, instead trying to get joints correct without any. Where absolutely necessary, currently I've used green Squadron (?) filler - it's used commonly by aircraft modellers, and I've used Humbrol stuff in the past. I tend to try and avoid 2 part mix things, both in filler and adhesive as they tend to work 9 out of 10 times, and not mix properly on the 10th. Its why I only ever use epoxy where I really have no other option - e.g. front steps on the V1.

Satin varnish here was Phoenix Precision. Make sure it's mixed well though, or it'll come out gloss (guess how I know....  :confused1: )

Cheers,
Alan
