| 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, (...) (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)

| (...) Couldn't you use an equilateral triangle to construct a 120-degree angle? Like the top picture that Thomas posted, but either Technic beam extends two holes past the point where the two beams pivot. Then a simple 3-hole 1/2-wide connector (...) (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)

| (...) Here's another way to construct an equilateral triangle where you attach to the sides (120 degrees apart) (URL) can of course use hinge plates instead. If you attach technic plates, you could then attach technic beam holes to the technic plate (...) (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)

| (...) David, The method I've described is complex. Maybe more so than you need. It can be done other easier ways, as shown by other postings. I will describe it in detail here and once you've seen it, can adapt or discard as you choose. If you want, (...) (23 years ago, 19-Jun-01, to lugnet.technic)
