Ok,once more in to the breach
,this is a commision build K-13....seems l get all the good jobs
l will be taking this build up to the ready to cover stage,and as peter balcomb can confirm, there is a lot of it,
these first few pics are of the parts laid out on my bench,the red object is a nice 3d printed nose cone,l will be using 3d printed airbrake arms supplied and designed by cliff,who also supplied the nose and the kit, Jilles plan/design is well up to his usual high standards,and cliffs cutting is faultless....l hope the new owner has a big car/van because this is going to be a biggie, l had to add 18 inches to my fus jig
more later
now lets see if l can get these pics to upload!!!..jack.

Just received this kit myself and am looking forward to seeing these build threads. Beautifully cut kits and well packaged for its trip to the states.

Looks like a fascinating (if somewhat daunting!) build. I'm intrigued by how the 3D-printed nose cone works. Does it take the full load of the snatch from the towline or does it get reinforced in some way?
Trevor
P.S. I do realise that, if it was a CW design, it would be filled with car body filler laced with lead

I will reinforce the inside of mine with glass cloth before I get it to Peter.

Morning trevor.....l dont intend to transmit any actual load to the nose cone,all load will be fed into F1/F1A
and dispersed in to the keel and the rest of the structure....l will be detailing how l do this a little later,jack.

OK, attached a drawing with a modification how to transfer loads to the front formers F1/F1A.
This is for the tow release setup I suggested on the ASK13 drawings. Those who choose to use an other tow release have to make up their own invention.
Cheers

Thanks. That's all clear now. I do remember being rather concerned when retrofitting my first aerotow release into the balsa noseblock on a 100" thermal soarer. I was surprised (as well as relieved) that it never did get torn off.
