Rope & Counter Weight
We'll need a piece of nylon rope – I used a piece of braided nylon string about 30cm in length (2.5mm⌀). We'll need to add weight to the holder. You can use material such as BB ammo, hardware screws, bolts, ball bearings, etc. I used a dozen 608ZZ ball bearings from an old pair of inline skates.
Our ball bearings weighed in at 132 grams. This should be enough to counter balance the solder iron.
