Step 4Board holder
Now we don't wanna keep dunking our hands in the solution (espescially seeing as FeO3 is sooo bloody staining)... so we make a small harness for PCBs
The harness will accomodate the boards and allow bubbles/currents to flow through.. for this we need out £1 waste basket!
Cut the mesh stuff out of the bin (note the large holes) and fold back on itself to create a small pouch.
At the bottom of the pouch i used a lighter again to soften the plastic. This is so is do not over stress the plastic and make it snappy snap. This way, the plastic moulds to a v shape.
Check the plastic is the right size for the tub and then start attaching it to the lid with cable ties. The lid of the container seemed a lot softer so i just drilled these holes out and stuffed the cable ties through.
Attach the harness loosely to the top so that it is free to move inside the container.
