The idea for the table-Top Scissors came from a discussion I had at work with a colleague in the workshop. We were talking about things which could be motorized, and for reasons only known to him, he said scissors.
So I got to thinking on how best to do it......
Step 1: Materials & Preparations
There are two different cutting actions, one which moves an entire blade forwards to cut the paper, and another, the one we are interested in, rotates a blade around a point at one end. The rotating action is identical to cutting with scissors and with a bit of jiggery-pokery we should be able to get as much control from the cut as you can with a pair of manually operated scissors.
I'm going to be using an old Epson M147B thermal receipt printer as the donor for this project, any receipt printer will do so long as it has the correct cutter. We'll need to strip the machine and remove all the fun parts. The two main items are the mechanical cutting blade and the fixed blade.
Scissors are sharp. Please avoid cutting yourself. Blood will stain wood, clothing, and your reputation. Take care, and keep any rocks away from the scissors.
Parts used from the Printer;
- The mechanical cutting blade.
- The fixed blade.
- The power switch.
- One large gear.
- One small gear.
- One Extension Spring.
- 12v-24v DC Motor Controller (link).
- 2 x 4-Pin sockets (link).
- 2 x 4-Pin plugs (link).
- 2 Meters 4-Core cable (link).
- Wood Stain (link).
- Various Screws.
- 1 x Compression Spring.
- Electric Hand Drill.
- Electric Hand Jig-Saw.
- Sanding Block.
- Needle Files.
- Screw Drivers.
Searching on Google for the motor's model number (FK-180SH) brought up a datasheet detailing the motor's power specifications. Using this information I selected a 12-24v DC motor controller.
