Plan pack, what is it

What is a plan pack

The plan or plans (as there may be more than one sheet) are designed in such a way as to give the builder a working drawing on which to build his aircraft. The builder literally pins down onto the plan his wooden parts, glue's them together and then when they are fully set he removes them from the plan in order to then commence the three dimensional assembly of those parts resulting in the construction of a fully working airframe.
The pictures below are to give some idea of what we produce.
The patterns are shapes of fundamental parts which may or may not be fully shown on the plan. These are printed on self adhesive paper to enable them to be cut out & conveniently stuck onto the timber being used making the cutting out procedure much easier.

The ribs are wing ribs, pre-cut to the wing aerofoil shape and slotted to accept the wing spars. Although these can be cut by the modeller, we offer these as an option as there are quite a few of them and they need to be accurate with each other in order to ensure that the wing panels stand the best chance of turning out straight and warp free. Most modelers opt for them as it helps to give them a good start with the project.

The cabanes are the supports for the upper wing of the aircraft. In some cases these are fabricated from durable Aluminium (dural), we can supply these pre-bent items when that specific aircraft requires them.

This photo shows a plan & the sticky backed patterns to its left, as in one of our plan packs.

This photo is showing a typical example of the hardware we supply in our plan packs. (Barnstormer 72)

Right, rib pack (old bandsaw style)

These are the new laser cut ribs. They appear to be just lines drawn on the wood whereas they are in fact cut all the way through and retained in the board by leaving small tags (uncut gaps) to keep them attached.
