The Drilling

  1. Let’s start from the upward facing side, the front facing you. Centre of the chopping block, a 6mm hole that’s 20mm deep. On top of that, add a 6mm deep 17mm hole. These will serve as the spindle holder with a ball bearing space
  2. From the centre, go 120mm right, and 120mm down. This’ll be your on-off switch, and your front. Drill a 6mm through-hole, and watch whatever you’re drilling on top of!
  3. From the centre, go 150mm left, and 150mm up. Drill a 17mm through hole. This’ll be your exposed motor pulley.
  4. From this hole, create 4 6mm through holes in a 31mm square. This’ll be your motor screwhole.
  5. From the centre, go 150mm right, and 150mm up. Drill a 20mm deep 6mm hole. On top of that, add a 6mm deep 17mm hole. This’ll be your tonearm cradle.
  6. From the centre, go 135mm right, and 135mm up. Drill a 6mm through hole. This’ll be your tonearm cable path.
  7. From the centre, go 150mm right. Drill a 20mm deep 6mm hole. This’ll be your tonearm holder
  8. Flip the chopping block! You should now have the back of your block facing you. There’s five hole bottom right, two bottom left, and one top right. Correct? That’s easy enough!
  9. From the centre, go 120mm right, and 120mm up. There’s a hole here, right? Drill a 17mm hole so that you’ve got 5mm left of the original 6mm hole. So if your chopping block is 35mm thick, drill a ~29mm deep hole. This’ll be the space for your toggle module
  10. From the centre, go 150mm left, and 150mm down. There’s a hole here, with four immediately around it, right? Here’s the tricky bit: drill a square that’s 44mm x 44mm here, so that you’ve got 5mm left of the original 6mm holes. So if your chopping block is 35mm thick, drill a ~29mm deep hole. You’ll have to drill quite a few holes to create a square. This’ll be the space for the stepper motor.
  11. From each remaining corner, drill a 17mm hole 40mm in from each side. This will be where your legs fit in.
