Channel 3-way intersections

So another valuable thing I have discovered with these two systems is the ability to join 3 pieces of channel in a very secure fashion. From what I know it appears that this can be accomplished at any location on the GB(goBILDA) channels. The ability to join channel like this is essential to build a sturdy robot. In my experience, we had connections like this every year and they really helped make our robot rigid. Also it is important to note that these type of connections serve a great point to convert a GB drivetrain to a Tetrix, you can see in my pictures how this could be accomplished. This is by no means the only hole spacing way to do this, depending on which spacing your cross beam is you can bolt on in different ways. Essentially by adding upright Tetrix pieces and channel you can covert entirely back to a Tetrix spacing while maintaining a GB drivetrain with bearings. Then if you need to add a supported axle again you can throw on some low-U GB channel with bearings right on to Tetrix (this will be covered in another post). Anyways pictures are worth 1000 words so maybe this helps spark some ideas:

This last pic shows adding a GB channel in the same fashion, it bolts on just as easily.
