Step 6Drilling & Tinning
Nearly There!!!
You'll now need to drill all the holes in the board. I suggest getting a drill press accessory for your dremel to do this, although I'm sure you could do it fine with a steady hand and a bit of patience.
I drilled all the LED/cable holes with a 0.8mm bit and the screw holes with M3 bit. Then using the cutting disk I cut the board to shape and finished the curved bits off with a tubular sanding bit.
Moving onto the last stage we'll need to clean the board ready for tinning (making it look a pretty silver while stopping the copper from oxidizing over time). I use the fine sand paper again and finish off with an abrasive pad & alcohol.
Fill your tray with enough Liquid Tin to cover the board and gently rock it back and forth. You should see the copper start turning silver immediately, but give it a few minutes to finish off before washing the whole thing under the cold tap.
