 | | Migrating from IR tower/spirit.ocx to USB
|
|
Now that I have a 2.0 kit and have had some time to realize that the new USB tower uses a proprietary protocol I can see that rescuing all the code I’ve been writing in Visual Basic will be tougher than just redirecting the IO to a USB masquerading (...)

(I never thought about this until just now, I know these things as "bushings" and they are listed as "bush", which only now seems appropriate when they are activly in service, as opposed to sitting in a bin. If I had an www.oed.com account I would (...) (23 years ago, 23-Aug-01, to lugnet.robotics)

(...) I don't have any hard evidence, but I've always found that the type 2's (later version) grip a little more consistantly. The type 1's in my collection are either *really* tight or just moderately tight. Type 2's seem to be consistantly (...) (23 years ago, 23-Aug-01, to lugnet.robotics)

(...) They're pretty much the same. But I think Type 1 bushings often have a tighter fit than Type 2 bushings. It really depends on each specific part and its particular tolerances. I have some Type 1's that are extrememly tight fitting, and others (...) (23 years ago, 23-Aug-01, to lugnet.robotics, lugnet.technic)

(...) Based on my experience, out of over 200 Type 1's that I own, only a few have ever split in half. Having recently acquired a used 8880 supercar (which uses Type 2's), I now have over 20 split Type 2's, and that number keeps increasing with use. (...)

(...) Type 2 is newer, probably because the Type 1's were too hard to take off the axle. I've noticed that most of my loose Type 1's have a hairline fracture on one side. (...)

(...) Note also that Type 1 & 2 are also slightly wider than a smooth 1/2 bush - about half the thickness of a tooth wider.
