Hi! all Europe and the UK patrons' Please note there is a small (and obvious typo like" The Kings Speech"!) in the web page address but it gives me chance to sing about it also ! The correct address is:- www.wickenbyairfield.com Full details(and arrival instructions) of the 2011 Wings and Wheels Air Show event will soon to be found on the web page . It's quite possible that the annual event of Project Propeller will also be at Wickenby but the weekend prior on Saturday 11th June so we may get to share the same Marquee the following weekend with more reasonably priced evening entertainment for the Saturday 18th June. Unfortunately our date clashes with Aero Expo at Sywell that weekend so why not have a "flying" visit to Sywell then come over to us for overnight camping and attend the evening event or even do it in reverse leaving us on the Sunday morning for Sywell. Our Air Show plans are "something else" and will be a privilege to watch.

The main pip pin is about .499 so only a tiny amount of play is available. Normally, the oversized bushes allow what appears to be excessive play when the wings are not rigged. When the plane is rigged, those sloppy bushes get hard to align unless you were superman during the cockpit module build up and got the fuselage and wing bushes just perfect. I only have two aircraft that align so well, the wing pins slide in easily, but that is only at 85 degrees and with the tips held just right. Hotter or colder, or with an untrained assistant, it is tougher to push the pins in. So what to do? Since none of us is superman, I many times have re-aligned the bushes on final wing rigging by heating my spare tapered black pin until just too hot to touch, but not sizzle (180F), and ram it home. Let it set overnight and the three bushes get aligned. Once in a while, I do have to put my 1/2 inch reamer into the pilot side hole and knock a thousandth off for a nice hand fit of the pip pin because of the tighter tolerances. Note: There is a good reason for using the pip pin when doing spar alignment, especially on the glider wing retrofit. Unfortunately we don't have the luxury of setting our own bushes with the short wings. If we follow the instructions blindly and use just the bolts, you won't quite get perfect alignment. So just heat the pin and help the bushes align. Please do not overheat your existing wing pin and destroy the heat treating. At 6 Gs, you would not believe the shear load on that pin. So don't rip everything out just yet, try a bit of heat and patience. It's worth it.

But on my own it is more difficult. A couple of years ago I inherited a tapered 1/ 2 inch pin from an aircraft engineer and that works just fine. I tap it in carefully with a plastic hammer=2C and can then insert the pip pin into the other hole with ease. I don't now where one would buy such a tool.

There is no slop when the whole thing is assembled and the pins are a light pus h fit. Is this normal?

I'm wondering if anyone can recommend a method for attaching the joined end of a thermocouple to a flat aluminum surface...I've some situations where clamping is not possible...I expect to have temperatures in the 150 to 200 deg. F. range...will be measuring coolant temp at inlet and exit areas of radiators...(non-Rotax powerplant).
