Wing Jig
Construction Instructions

Introduction
The EBMA Wing Jig is produced in a combination of 3mm and 6mm MDF. As such normal DIY
woodwork procedures can be applied to them. The parts are cut by a laser cutter which results in
smoke marks on the surface of the wood. One side of the wood will have slight marks and the other
will be more pronounced. Some parts are symmetrical and you are therefore able to choose the
visual effect you wish. For asymmetrical parts if you wish to remove the smoke marks then fine
sandpaper may be used (use a sanding block, not just the paper on its own).
Where glue is required during assembly a good quality wood glue (PVA) should be used. When
wiping the excess away wherever possible wipe it towards the burnt edge as this marks less.
Dry fitting components prior to gluing is highly recommended, i.e. compulsory! You should also
use an engineers' square during construction to ensure that everything goes together absolutely
square.
Whilst parts are drying it can be handy to hold them in place with masking tape. This can be used
to help keep gaps closed.

- Page 6 3. Using the support from step 2 and the base unit glue the two tab locators to the long piece. The centre line on the long piece should face upwards. A small amount of glue between the top surface of the long piece and the tabs is all that is required.

- Page 8 Using the Jig Holding the Fuselage 1. It is important that the fuselage is held centrally and vertically on the wing jig. To aid this there is a centre line cut down the middle of the jig. The two vertical...

The extension piece can move from side to side so care will need to be taken that the centre line is correctly aligned. Elastic bands can be used around the hooks of the supports to aid holding a fuselage in place.
- Page 10 Setting the Horizontal Stabilisers 1. With the fuselage held centrally and vertically on the jig select the pair of Wing Setting Guides that will support the tail plane best. This largely dependent upon the height of the stabilisers above the jig. 2.
