"rotate the tube" - towards you, or away?
It appears there is more than one way to "turn" a bowl.
I find for that for the softer plastics (like thin polyethylene) it's ok. I've noticed that the loop will pop out of the plastic when it's under stress before the wire will snap.
I've used these techniques to repair recycling bins, body molding or cars etc.Brilliant idea using crimped staples as a reinforcing bar. I was using strands of steel aircraft or copper wire with loops in both ends up until now.Another good material for strengthening the joints after welding / reinforcing is fiberglass cloth. I use a 260/200 watt gun with a flat tip to melt in into the plastic (start at the center of the cloth & work your way outwards - avoids wrinkles).Used the latter on the holster for my cell phone after I snapped one of the "wings" off getting out of a car.
When using the numeric method of assigning permissions in Unix/Linux, the values are in octal. So, you have three "masks" for each file's permissions. Owner, group, & everyone else. Like so:OwnGrpOth421421421rwxrwxrwxYou add up the values for each permission granted for owner, group, & other. Typically for a script you'd want the owner to have read, write, & execute access, while granting only read & execute access to the group & other users.Owner (4+2+1) = 7Group & Other (4+1) = 5 (twice)chmod 755 filenameHTH.
Don't be so hard on yourslef.
Scared to build this.... Looks too much like a puzzle box from the Hellraiser movies.:)
