I can see how this tool would be very useful, but with all this experience have you seen any elongation of the bushing in the spar? If I understand how this works, it applies a concentrated load where the smaller diameter of the tool contacts the larger diameter of the bushing. The tool is hard and the bushing is relatively soft? How is this tool not a reamer? http://en.wikipedia.org/wiki/Reamer

The one I use is machined out of a hard plastic - I think nylon. Works great.

Do you have trouble getting your wings in place that last little bit to

insert the wing pins? Then this is the tool you need. Nearly 100 tools have been supplied for 25 different glider models from 9 different manufacturers. Everything from wood to self-launchers. $80 in the US and $95 outside the US. Shipping included.

"Correct" grease? So far I've only dealt with one glider that is specific about what to use. The manual for my club's L-33 has a spec that crosses over to a MIL-G number that is equal to Aeroshell Grease No.6.

My ASW-15 manual just says "use a non cold coagulating grease." I've been using Aeroshell Grease No.22. They work well but 22 and 6 are a lot harder to clean up if you get them on your clothes than ordinary white lithium!

Modern synthetics are very temperature stable and (for me) much less messy than traditional products. Super Lube was recommended to me by a farmer I "visited" years ago. They know machinery!

When I bought my current glider is '03, I bought Spindleberger's black Delrin eccentric tool offered as an option. It had a steel pin reinforcement pressed in concentric with the small end.

I "copied" his design with some "bumper improvements", and sold his :c)

Improvements include:

Small dimple drilled in handle end and filled with white paint to indicate position of small eccentric pin. Useful in determining which way recalcitrant hole needs to move.

3 "stacked" through-holes in handle end, drilled 120* from each other (thus offering 6 holes spaced 60* apart for steel handle to insert.

Handle end bent at 30* to offer a total of 12 potential "positions" for handle in tight quarters. (in use, it's rare to use the handle at all . . . no need as the handle end with the cross drilled holes provides plenty of grip to turn the tool by hand. Knurling the handle end would do just as well)

Of the several things I make and sell for gliders, the eccentric tool isn't among them as it wasn't my idea - - though doubtless any patents would have long since expired.

I'm among the Super Lube grease crowd. It's especially good in cold weather..
