This job is for a one off simple metal disk, to be used as ballast for a Hakko 599B soldering iron sponge pot.
The diameter is 65mm with a thickness of 15mm.
Tolerances are +/- 1.0 mm, The material is to be mild steel.
Quantity one off.
The finish need only be smooth with no burrs (so I don;t cut my fingers installing it). It's not on display so it doesn't need to be polished.
