Earlier this week i took a shot at the first wing half. As clear in the foto this mould is too complicated to make in one pièce.You could try but it would be very hard to de-mould because off the vertical sides off the wing(root).So at the ends off the wing i placed a board to work against.

Hello again,

The moulding continues !

With the root and tip -sides waxed and the PVA (polyvinylalcohol) dry they are ready to take the moulding resin and the epoxy with the glass cloth , same as the other parts .You have to be careful not to disturb the PVA.20190511_215905.jpg

With the edges cleaned up (sorry :no pic) i placed two supports over the wing at 1 third and 2 thirds off the wingspan to make sure, when the mould is turned over to make the other side,it dousnt get warped.

This is visible in previous pics.

So let's turn it over ,remove the supporting board,loose the foam and clean -up the underside !20190514_222536.jpg

The black part in the foto before the last is the underside off the three moulds wich are going to serve now to work against to make the opposite moulds. therefore they need to be waxed like the wing...again.

Two more to go and we have a complete wing mould !Normally three (like the upper side :tip , center and root)but i'm going to try to make the bottom side in two parts :center with tip and root side. I'm sure it will come off....i think.

In the last foto you can see the metal braces to keep the moulds together(bolted to the vertical side off the parts)

So this evening i'm doing the first bottom part...fingers crossed !

First bottom mould is a fact !!On the right side you can see again a supportig board (vertical).This will be the border between the two bottom moulds .This time no division at the tip.(Unlike the upper side)received_462575964502626.jpeg

Forgive me for asking,

Have you made the wing already, then waxed it buried half the wing then covered the exposed part of the wing in fibreglass to make one half of a wing mould then repeat the process on the other side .

So you end up with a split wing mould .

Correct Stephen !I couldn't have said it better. I know it sounds crazy but in the end it will be faster to make multiple aircraft in the moulds that to make them one by one from scratch.I also hope to get the weight down and the strenght up compared to a wooden airframe.Thanks for the comment !
