mhaselden Posted May 9, 2017 Share Posted May 9, 2017 This was posted on Hyperscale but thought I'd share it here. Never tried the technique but the results achieved in the photos are pretty impressive. I imagine the technique would also scale quite nicely for those who work in the braille scale by simply reducing the number of sheets in each layer. https://www.facebook.com/groups/848474938507986/permalink/1530849163603890/ Hope some find this interesting.

Beardie Posted May 9, 2017 Share Posted May 9, 2017 Hmmm interesting I wonder if there is some form of resin that you could soak the paper in rather than using CA. I recall recently idly watching one of those 'How it's made' programs on telly and they were making laminate covering for worktops and such by a process of soaking big rolls of printed craft paper in some form of resin.

Bughunter Posted May 12, 2017 Share Posted May 12, 2017 Sorry, but I think wood will look better. At least with that kind of thin paper, because there are too much structure within one layer. A example, how wood can look: It is one for my Pfalz D.IIIa in 1/48, made from pear and boxwood. Note the shape of the plastic airscrew is wrong, since mine is using a "AXIAL". Front side after basic shaping: Back side: Make it stronger with primer and color: The size matches now: Compared to the original one, front ... ... and back: The final view: For more pictures see here: Pfalz D.IIIa Also 4-blades are psossible, here on for my D.H.2 Stripdown The sentence with the "skill" seems to be right More pictures of that biplane can be found here: http://www.britmodeller.com/forums/index.php?/topic/235020509-airco-dh2-stripdown/ My other biplanes shown here in the forum use often wooden air screws too. Happy sanding! Frank 12 Link to comment Share on other sites More sharing options...
Bandsaw Steve Posted May 12, 2017 Share Posted May 12, 2017 Fabulous job Bughunter! I might have to have a crack at this one day following your excellent example. 👍 1 Link to comment Share on other sites More sharing options...

These look fantastic Frank. Can I ask, what thickness are the wood strips you're using and what tools do you use to shape the laminated blank? 1 Link to comment Share on other sites More sharing options...
Bughunter Posted May 19, 2017 Share Posted May 19, 2017 (edited) Of course The thickness depends from the original airscrew. I check the size usually on the drawings, e.g. in a Windsock Datafile, for the overall thickness and then count or guess the layers from pictures. A division tells you the needed layer thickness, typically around 0,4...0,6 mm. For some kind of woods you can find veneer in the internet. This the most problematic task, because you need only a small amount and not a huge number of square meters, and on the other hand only some kind of wood are usable, e.g. the thread starter has used linden tree which I think is to structured as many kind of woods. Mahagony for example has to many water channels for that small scale. So if i have veneer, then I sanding down a stripe to the needed thickness. If I have a small block, like my boxwood in the picture above, it have to be sawed to veneer before. For this task I use the small circular saw Proxxon KS230. The shaping is mostly done with careful sanding. For the rough shaping a micromot hand mill or even a very special tool, which I own: a "violin making plane" (a bit hard to translate for me): But most of the work to carefully sand it with fine sanding paper.

Howlindawg Posted May 19, 2017 Share Posted May 19, 2017 Thanks for that Frank, very informative. I think that tool is called a 'finger plane' in English. 1 Link to comment Share on other sites More sharing options...
