Its about time I posted the latest progress on the Skylark.
I glassed the inside of the fuselage in the cockpit and nose area. This involved cutting out lots of little glass cloth patches which fitted between the formers and longerons and pasting them into place with laminating epoxy. It was a bit of a “faff” but it will add a lot to the future strength.
The nose planking was finished and a pile of laminated ½inch balsa slices added to the nose before carving down to shape. I have been able to add a couple of blocks of lead inside the nose and still leave room for more if /when necessary. It took me a couple of mornings of sanding to get the nose cone to what I felt was the right shape.
I have now started on forming the canopy frame. More on that when it is complete.
Brian. :)

That was the "during" shot Barry, check out the "after" shots - even the glue bottles are standing to attention.

I don't care, you have mess and that is all that matters.

However, I must say that your mess, is tidier than my tidy.

I have spent a pleasant morning completing the canopy frame. I intend to hold it in place at the front with a short length of dowel and with magnets at the rear.
I have now started on the fuselage fairing that fits over the tailplane. I usually make three or four of these before I get one that fits anywhere near properly.
I have to say that I am thoroughly enjoying working with balsa, spruce and ply once again.

Well that wasn’t too bad. I managed to construct the tailplane fairing without any difficulty and it fitted perfectly after a little fettling. No one is more surprised than me as it usually takes up to four discarded attempts before I get a fit that I am happy with.
Once the tailplane is bolted to the fuselage, the fairing slides in sideways behind the fuselage former and under the lower fin. It is a friction fit and I hope it stays in place in flight.
I think the next job on the fuselage is the covering with glass cloth. However I am going to wait till the centre section of the wing is constructed before I do any more with the fuz.
Brian.

Hi Brian

Rather than rely on hope and that spoil what will turn out to be a nice model, how about a couple of tiny magnets front and rear just to hold it in place such as the ones on the link below in various sizes?

I don't know that I've used this Co before but I have bought magnets from eBay before and they are very strong. Don't go too big so that the fairing will separate easily on demand
