Yes - it looks like the lower lock bolt? is stuck. I had a neighbor, my wife and a hoist help with the OTA placement.

I could take the weight of the OTA (with the hoist) and then try to loosen the lock bolt. Never thought of trying it first.

Have someone from the local club that has a G11G kindly coming round this morning, and I'm sure he will have a few tips too.

Don't loosen the button head in the center, that is the pivot for the entire head. The only fasteners you need to loosen, and just barely - for elevation are the TWO upper button heads on either side with the arcs cut out of the side plates. If they are too tight get a proper long handled 3/8" socket wrench and a short extension with the correct size hardened hex socket to avoid hurting yourself and/or slipping and scaring / damaging the mount. These fasteners should never be tightened this much again, it only takes a small amount of torque to hold the worm gear driven elevation mechanism in place.?

The M12" SCT is a heavy bugger but the mount is designed to carry it. With a near limit payload and counterweights on the CW shaft when raising the elevation it can help to reduce the force on the elevation mechanism by lightly lifting the CW shaft.?

If you need a strap wrench to turn the elevation knob there is something wrong - STOP and figure it out before you damage the elevation mechanism!??
