Not much I am sorry to say. I have bought a few pieces of hardware - a good hinge, angle aluminium and a threaded rod with 1mm pitch, which I could use for a 1-axis adjustment. But I still have not come up with a design for two axis adjustment which I could make with primitive workshop facilities.

I am still searching for a solution. Recently I saw an equatorial mount for an astronomical telescope on e-Bay. It had two slow motion hand drives working on worms, which were geared at 2 degrees for one 360 deg rotation of the hand knobs, so the laser beam would I think be nicely settable to 1 minute of arc. I bid to my maximum (£46) and this was not sufficient as another bidder had set a higher max bid price and so got it for £47.

I am still very much on the lookout for some way of doing the fine pointing.
