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 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?
Any help would greatly appreciated.

put the two
one on top of the other.
On the middle of the top one put one  , on it one  and on it one .
The hole in the top can now be braced to the bottom beam with a  .
You can also put one of the below the beams, if it’s better for your application.
It’s bulky, but if that doesn’t bother you it’ll work.
HTH,

If you have no plates, put four bricks on top of each other between the
beams and use a 7L liftarm rather than the 5L one pictured above.

Thanks for the ideas... however I am constrained to a height of 2 beams.
This height restriction is what is causing me grief as I can not space the
beams or add above/below to use the liftarms.

You could try a cam with an offset of 1 hole sideways along the beams - the
distance between the offset holes is about 1.5L (12mm). Use the hole in the
middle of the large end of the cam as well as the hole at the small end. You
probably need to do this one way round and then the other for maximum strength.
I think the overlap above or below the beams is a couple of mm. If you need no
overlap at all, you could always cut off the excess :-) I’ve been wanting a 1.5
offset liftarm without the bulky bits for a while!
