Mar,
I've never seen a caster as small as you describe, but I have
seen something that might work. I use a "captured ball" bearing
instead of a caster on my robot, and it works really well (no
swivelling needed to change direction). I got these at a woodworking
shop, they are used to make work surfaces that things can slide on in
any direction easily (think of a board sitting on a bunch of
track-balls). I mounted it ball-down and, like I said, it works well.
It's probably too big for you, though; it's about 1.25 in. high from
ball to mounting bracket. Now, the thing I'm remembering is very
similar, but much smaller. It was a "puck" for some sort of game
where you slid things across a board. The "pucks" were made of a
steel ball almost completely captured in a plastic (nylon, maybe)
casing. The ball was about 3/8 to 1/2 in. in diameter. The plastic
was thick enough that you could use it as a mounting. I'm not sure if
this game is still made, but you might be able to find one of these
things if you ask around.

| I think you're talking about a game called Crossfire (it was very popular about 6 years ago), and there are still quite a few floating around (though I don't think they make it anymore), you should try some garage sales. BTW, the reason I know this (...) (27 years ago, 30-Sep-97, to lugnet.robotics.handyboard)
