(...) put the two [LDrawPart 3703] one on top of the other. On the middle of the top one put one [LDrawPart 3700], on it one [LDrawPart 3023] and on it one [LDrawPart 3700]. The hole in the top [LDrawPart 3700] can now be braced to the bottom beam (...) (19 years ago, 5-Oct-05, to lugnet.technic, FTX)

Ok... I have a question that may just show my ignorance... but I'll ask anyways. I have a need to strongly connect two technic beams (one on top of each other). Simply attaching them on top of each other (with Lego studs) is not strong enough for my (...) (19 years ago, 5-Oct-05, to lugnet.technic)
