Max made this project with selfmade custom lengths. The beams were 200mm and then cut to 185mm.
Max his tools: clamps and a hack saw."Hi,
So I ordered another lot from chartup.com and when this lot arrived they were the new version where the centre holes goes all the way through. Excellent! I cut them to length using clamps and a hacksaw in my kitchen. Then tapped the threads using an M3 tap, a power drill and some bicycle chain oil. It all worked perfectly so it is possible without proper tools :-)
