Well, it looks like I should have made the climb to get the truss back on the 6-meter beam. They're forecasting winds pf 40 and gusts to 60 MPH for Sunday. The system has seen worse, but not with the

If you can find it, try some Beryllium Oxide Grease. BR-2. It is a very slippery, high pressure, low RPM, grease that looks much like graphite, but it is much better. It's a bit easier to apply than
