Yet another way to combine/mount pulleys for multishaft weaving:
I had never seen dräll pulleys like these before. (Spotted at a flea market near me, and way too expensive just "for fun")
I think this way to mount them is asking for trouble: if the cross piece from which they are hung doesn't have the correct size, they will tilt. Even with the "correct" cross piece, there will be a completely un-necessary force on the axle.
No, if ever I go for dräll pulleys again, I think I will stay with the vertical arrangement.
