Hi everyone,
Like the subject says, I am looking for a lego piece that is 120 degrees
exactly. I am looking to connect beams at this angle. I measured the angle
connectors that I have (the ones used with axles), and it seems that the #4
is close, but not quite 120 degrees. The only piece I know of that could be
used is the three spoke rotor, but I only have two of those. I tried the
single angle beam, like the black ones that come in the mindstorms set, and
they are very close to 120 degrees, but have to be stretched a bit. Another
thing I noticed was that many of the wheels have 6 hole patterns, and so the
holes are 60 degrees apart, so I might be able to do something with them.
Odes anyone have any better ideas?
Rob

| (...) If you can't use the three spoked plate, I would go for one of the wheels. How about the small pulley? It is probably the smallest circular part you can find with six holes, with a 3 unit diameter and 1/2 unit thickness. Fredrik (23 years ago, 13-Jun-01, to lugnet.technic)

| (...) Hi Rob, It's going to be hard to connect beams at exactly 120 degrees. There aren't many pieces that have connections at that angle. I think the 3-arm rotors will work, as you suggested. The following link contains two quick ideas that I put (...) (23 years ago, 13-Jun-01, to lugnet.technic)

| (...) By using 3 of the 24-tooth gears set up into a triangle, you can set the angles at whatever multiple of 15 degrees you want. If you use the older gears, you get a direct connect to 4 peg-holes aligned for standard Technic building on one side (...) (23 years ago, 13-Jun-01, to lugnet.technic)

| (...) Hi Rob, Using 3 beams of equal length (any length) gives you an equilateral triangle with 60 deg internal angle, and 120 deg external angle. Of course, connecting the nicely isn't always easy.... Regards, ROSCO (23 years ago, 14-Jun-01, to lugnet.technic)

| Thanks to everyone for responding to my post. I have lots of ideas now of how to tackle this problem... ITs amazing how man ways there are to do this type of thing. I never would have thought of sticking 3 24 tooth gears together, as someone (...) (23 years ago, 14-Jun-01, to lugnet.technic)
