And he lives 15 minutes away from me! I gave him the beginnings of a Lightning fuselage pattern I'd made while in Germany. Meant for his jet engine he kindly showed me.

I am building a Brian Taylor Gloster Gladiator and the instructions on the plan for building the flaps are to start with 1/64" ply laminated with 'thin' litho plate. If the litho cannot be found does anyone have any idea what I could use in its place? I have absolutely no experience of litho so don't know what it looks or feels like.

Thanks

Graham

Litho plate is simply thin gauge aluminium. It. Was used for printing some years back. You can use come or Pepsi cans. Cut the top and bottom off then cut open the tube with a pair of scissors. To make it plyable / remove the springy -ness you will have to anneal it. There are some good videos on YouTube showing how to use litho plate and anneal it.

Many thanks for your reply Doc. I will give the Pepsi can a try.

I'm sure you could find a traditional offset litho printer who would have spare sheets, but if not, try K&S Metal Centre's aluminium sheet. It is wonderfully malleable and only slightly thicker than litho plate. Available in most toy/model shops. I have used it to make scoops, blisters and all the more difficult shapes on a 1/12th scale model of the record boat Miss Britain III, no annealing necessary.

The Airbus A380 used an aluminium/composite laminate called GLARE GLARE - Aluminium/Composite laminate

GlLARE gives a lot of the advantages of composites, with the workability of metals. It would be interesting to see what the effect of laminating aluminium foil/drink cans/lithoplate with different materials would be.

This is a Hawker Fury I am currently building, the fuselage top from the cowl to the rear of the cockpit is covered with Fosters lager cans the printing is still on the underside. I found it almost impossible to remove. The gun troughs were formed from baking tray aluminium which is the same thickness as the beer cans. rivets were embossed with an 0 gauge locomotive riveter.dsc_0556[277].jpg

you can buy aluminium sheet off ebay look for 0.3mm which is the equivelant to the thicker litho plate used to be 0.15 0.2 and 0.3mm thick .

i just remembered you can get sheet from 0.125 to 1.6mm so a good choice from this modelshopuk

The modelshopuk looks very good. Thanks for the link.

Graham, the reason for BT specifying litho rather than thin ply or some such to make flaps from is because, due to the thin section of the flap, it is prone to warp over time due to the instability of the wood.

This then looks 'orrible when the flaps are up as their trailing edge does not meet the wing trailing edge.

Since litho is now hard to find, many people are using laminated epoxy glass sheet known as various trade names around the world such a G10, Fliteskin or ProSkin. Mick Reeves Models in the UK sells it as ProSkin and it is available in many thicknesses to suit. It is a very stable, strong material and would work well for your application, but it is sold in rather large sheets and is not cheap - nor is the postage!

Hi Guys, A possible source for litho late are art schools. Many still use it, and throw away used sheets.

Also there is an interesting material called Flite Metal that comes from the US of A. It's easy to find on the web

FliteMetal is no good for Graham's application. He wants to make flaps. FliteMetal is a finishing method to replicate a metal skin. It's not a structural material.

Yes Alan. Of course, My only excuse, is that in my haste to be of assistance, I didn't read the entire thread.
