I needed a jig to collimate my laser collimator... so I dug in the kids' Lego box and came up with this simple design. I figured it may be useful for someone else!

There's another super easy way to do this, I found out last night, if you have a refractor with a decent 1.25", or 2", eyepiece holder. Just put the laser collimator in the focuser and point it at a wall, or whatever, and spin it. If the dot stays in one place then your collimator is aligned, at least that's what I've concluded so far. If anyone knows different then please post it.
If you don't have the refractor, Legos sound like an excellent idea, one of the better ones.
And, how stupid of me, should have added, you can also do a basic check simply by using the scope you will be collimating. Put it in the focuser, if there isn't a lot of play in it, just spin it and watch the dot. It also might be a good idea, once you start collimation, to mark the collimator and always orient it the same way in the focuser, I guess that might depend on some things.
