Quote:If the problem is adjusting the mount with the load on it, then, as recommended, you should adjust the mount without the load or phyically lift the head when trying to move it upward and let the weight move it downward.If the problem is that the latitude axis is too stiff to move even when the mount is not loaded, then simply replacing the handles may result in stripping the threaded holes and damaging the tongue that the rods push up against. The best thing to do in this case is to remove the side plates, disassemble the axis, and replace the set screws with thumb screws so that the tightness of the axis can be adjusted. The result looks like this:

Stars light the world without, to give us purpose
They light us within to give us reason
We live in a well-lit abyss.
Quote:The OP complained about the difficulty of adjusting the altitude while drift aligning - in order to drift align, you must have the telescope and counterweights on the mount. Still, I have no problem doing it by lifting up on the counterweights while turning the adjustment bolt, as long as I didn't forget to loosen the opposite bolt.

Quote:be sure to check the thread pitch, I've seen both M10 x 1.25mm and M10 x 1.0mm on EQ6 mounts (also a 1.25 forced into a 1.0mm hole)
As Astro Baby says, the stock bolts are made from stale cheese, a few £ spent on SS bolts is far better than stripped threads/bent bolts.
There are some on the market (can't find them now) that have a built in reversible ratchet handle
Quote:When you put new bolts in make sure to round and smooth the ends. Otherwise the bolt will damage the tongue that it pushes against. A rough end will also make the adjustment bumpy and more difficult.
Quote:It's the counterweights that matter.
Quote:The problem is that drift aligning requires a delicate touch. What I was looking for is whether anyone actually does this routinely. As I said, I do a polar align with EQMOD with no load and then add the scope and kaboodle. I have not dared to use the alt knobs for drift aligning.
