I finished my first project with a modular building system. It's based on Grid Beam but modified according to the openstructures
grid for metric units. The sticks are 4cm x 4cm and in this project all are 80cm long. The holes are 8mm big and the connectors 6mm, so I can move things around before fastening the bolts and don't have to be too exact at drilling. The tabletop is a 10mm plywood board.
The "Tri-Joints" are actually quite sturdy. (Not all holes drilled yet in this picture)
I built it using only hand powered tools in my flat, using this manually operated drill press for drilling the holes:
The sticks I bought sanded and cut to length for about 6,50€/m here
. They are really good quality and cut exactly. Still looking for cheaper options but it's an advantage to not have to cut and sand them. Sticks at Hornbach
are not much cheaper.
It's quite a basic design. I wanted to test the drilling machine and the GridBeam design.
Drilling by hand is quite a lot of work, especially all the holes that are not in use right now. But like that I can reuse the parts easily for other projects. The final assembly is quick and easy. My plans for the next projects are in modular design.
The drill press works fine overall. The drill chuck is not perfectly straight, but I thinks that's fixable. And due to the big tolerance with the system it worked well anyways.
