I have partially completed the right wing tip panel and have spent some considerable time setting up the joiner system between the outer and inner. Because of angled spars it was a bit of a messy job at times and it would have been perfectly possible to get it wrong. That done, it’s now time for the left tip panel to be started and repeat the whole process.

Progress on the Skylark has been slow but steady. I now have the whole wing structure constructed including the wing joiners. I have just finished adding the underside sheeting. It is now time to add all the innards such as the wiring, servos and airbrakes before I start on the top surface sheeting.

8ft 6in Vince. Plus another 4ft 6in bench behind the camera going across the end of the workshop. It's still not big enough!

I just wish that my bench had a similar ‘auto clean’ feature :lol: :lol:
Don’t look at any of my build threads Brian unless you are sitting down first :D

The most used tool in the workshop is the brush and pan Peter.

All the wiring, airbrakes and their servos have now been installed into the wing centre section. I have gone for a set of commercial top surface brakes as opposed to the over and under brakes of the original on grounds of practicality. I have only one aircraft with built up, over and under brakes, my Oly 463. On my usual slope site I have to slap the brakes away at the very last moment so that the lower blades do not get wiped off in the heather and rough grass. The brake units themselves are commercial units which I had in my spares box. They are slightly oversize and I suspect that the model will be over-braked but perhaps that is no bad thing.

Work on the wings has come to a temporary halt as I have run out of materials. Right at the start when I was working out my materials I made the classic schoolboy error of ordering enough 1/16 medium sheet balsa for the left wing and not doubling it up for the whole wing. Duh!
That nice lady Vanda at Balsa Cabin has jumped into action to sort me out with timber and covering materials but the package will not arrive till Monday evening. :cry:
In the meantime I have started covering the fuselage with 81 gm/m2 glass cloth and resin. It has gone round the complex curves quite nicely with a plastic roller and the occasional cut with a knife. :)

My timber order has arrived and wing building has been able to proceed. The centre section of the wing is now complete and sanded to shape. The airbrakes open fully and close down and lock in place. I still have to create the faring that fits over the centre of the wing to fare it into place with the fuselage. That will probably have to be tackled next. :?
While I was waiting on the arrival of my timber I spent a little time on the instrument panel. I am not after total scale accuracy, I just wanted something that looked reasonably like the full size. An hour or so with my camera and photoshop produced a respectable replica.
