Adam,
Funny that - I ordered the same triple pack today! Also got Vic Menard's book on Newtonian Colimation. Jim must be wondering what's going on in Australia?
I also made a mod to my secondary mirror holder today that I've been meaning to do for some time. I machined up a thin aluminium disc to go between the plastic cell and the three colimation bolts. This prevents the bolts indenting themselves into the plastic cell - making rotation of the cell easier.
