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 use. I am assuming that I need to somehow brace
them through the side holes but can not figure out how.
I need there to be just the two technic beams and can not space them with
Lego plates so I can not seem to strengthen them with liftarms as they
don’t fit nicely with just 2 beams. (ok... at least I don’t know how to
make them fit).
Any of that make sense?

How many studs of overlap can you have? Also, how much space can you have on
the sides?
A tacky way to solve the problem would be to run a string through the holes
in a spiral type fasion and then tie the ends together. Hey; no one can say
it doesn’t work!
BTW, what is this design for? If you show some pictures I might be able to
alter your constraints.

Thanks for your suggestions.
I have a number of restrictions for this specific design... but have been
wondering in general the best way. (So far I think Mark has the best
suggestion using an offset cam).
For this specific project I am attempting to build my first pneumatic Lego
project. I have chosen a cherry picker because my 5yr old son and I were given
a ride up on one at a local fair. I’m building the bottom arm connection. (I’ll
have to find a digital camera I can use and provide a picture)
My restrictions for this design are the following:
1. Studded technic beams (simply because I have them in quantity)
2. A max height of 2 beams (with a bit of extra room on top... say 1 plate
height... but it has to be on top, not between the beams)
3. I only have access to one side of the beams. The other is up tight against
other beams (but needs to move up/down relative to them)
4. Will not cut, glue or otherwise modify the Lego
Again... thanks for all the help.

| (...) The offset cam will be too tight. I believe Zoltan Schuster and Dennis Bossman have the solution. Turn one beam upsidedown and leave the other right side up This will make the verticle distance between the holes exactly the 45 degree diagonal (...) (19 years ago, 6-Oct-05, to lugnet.technic, FTX)
