    Refinishing gliders

    Or there's something like this to maybe add a few years: http://soaringcafe.com/2014/04/how-to-sand-your-glider/ plus some more aggressive sanding to the leading edge where the gel has blistered all along the glue line. I suppose I should take some photos...

    Refinishing gliders

    Yep - my London is in England! There are loads to choose from - Poland, Slovakia: http://refinish.pl/ https://www.gliderservice-novak.si/ Just wondering if anyone has personal experience // done some of it themselves. Plenty of very nice looking refinished gliders around the club so been...

    Refinishing gliders

    Mine's getting a bit close to that time I think (LS6A 15m). I could have a crack at doing the leading edges and the tailplane myself to add a few more years onto it but then I could just get the whole thing done properly... Anyone had this done recently & got ballpark figures for cost / a...

    CNC Foam cutter

    This thing is strictly for milling wood and foam - anything beyond that and I'd need to re-design it to be sturdier. For vinyl do you need a drag knife? I guess I now need to learn fusion 360 so I can output some nice Gcode.

    CNC Foam cutter

    The foam cutter is now also a milling machine! Or at least it will be when I replace the sharpie with a router.

    Matty's Marvelous Modular Monstrosity

    Two elevator halves ready for whatever the next bit of the process might be. I suspect it's trimming, joining, wrapping some more bi-ax over the join area, cutting out some bits for hinges, filling, sanding, painting, mass balancing... Basically done then! 490g each which is sort of about right...

    &%%##^* Splines!!!

    Draftsight is quite limited re. Splines from what I've seen but getting a decent result is not too difficult and the program overall is really good IMO. AutoCAD knocks it into a cocked hat though and you can get it for free by clicking the 'i'm a student' button (and who here isn't a student...

    Is electric flying safe today ?

    You'll never believe what happens when you set light to gasoline! Especially if you sort of spray it about a bit first... I really don't understand the hysteria re. Lipos. They're fine IF DESIGNED, MADE & TREATED PROPERLY. Same as gas. Different challenges sure...

    Wing Locating Pins & Main Pins & Spar caps.

    And here's some nice drawings from the LAK 17 manual. Pins are in the fuselage going into fittings in the wing root.

    Matty's Marvelous Modular Monstrosity

    Today I have mostly been battling Solidworks... Black is carbon / kevlar / carbon. Red is crash reinforcement: Rollover protection set into the bulkhead behind pilot (also behind pilot: 100kg of LiPo batteries(!)) cockpit rails of uni carbon, kevlar and foam and a front bulkhead. That's about as...

    Wing Locating Pins & Main Pins & Spar caps.

    Breathing a bit of life back into this old thread... For Lift Pins an easy way of doing it seemed to be to cut down some AN Bolts and push them into spherical bearings. Guaranteed strength parts with little modification and nice and self aligning. Is there any reason this is a TERRIBLE IDEA...

    Matty's Marvelous Modular Monstrosity

    Anyone got a ballpark minimum thickness for carbon at a trailing edge so you don't slice yourself open on it and it doesn't crumple as soon as you look at it? 1mm? I'm thinking that my 2*265gsm will be really thin.

    Matty's Marvelous Modular Monstrosity

    10mm x 1mm Not 100% sure how I'm going to turn them into bundles and make them into a spar yet. Glue them together then incorporate them in the spar, or do it all in one operation?

    Matty's Marvelous Modular Monstrosity

    Last day of holiday and my colleagues are annoyed that I'm getting big packages delivered to work! In this case a 250m bobbin of carbon pultrision! Gonna have a bunch of stuff to get on with when I'm back!
