I am building a guitar amplifier from a kit, and the motherboard was made of cheesy cardboard. I decided to make mine out of phenolic. This is one of my favorite materials to work with because is is easy to machine, and it looks beautiful. In this instructable, I will run through the steps for laying out the new motherboard and drilling/cutting it out. The phenolic I am using was salvaged from an old transformer. (Recycling... Yay!)
Step 2: Check the hole size
Step 3: Mark the Holes with a Transfer Punch
Using a ball-peen hammer and light blows, I tap the transfer punch, making a mark on my new piece.
Step 4: Off to the Drill Press
Step 5: Cut it out on the BandSaw
I used a push-stick to help move the piece through the blade.
