Drill holes
Then, you have to drill holes
- on the both sides of the 392mm beams.
- on the both sides of the 850 mm beams.
Drill two separate holes and then pierce between them to create a single one. The hole must be long enough to insert the nut. Be careful to not broaden it too much.
TIPS : you can drill the corners with a small drill bit before you drill the big one.
Next, drill the other beams normally, with a 10mm large bit. You can drill them with a larger bit a few mm deep to drown the head of the bolts.
