The cut point is wrong! Clearly, where he draws the first line on the belt (3:11) it is only just long enough to go down one side, round the pulley and back to the other end of the track. He then cuts it 4 teeth shorter than that! There's obviously not enough belt left to go round the idler. At 7:10 there's an edit where he must fix his mistake but never mentions it. I'm glad I didn't blindly follow these instructions and measured it myself.
I don't care about the measurement. I just needed to know how to get the belt to connect while in the channel. I'm used to working on cars, where belts have idler pulleys.
Clear as mud!

What brand/supplier for this curtain track system? Thanks.
