- Draw your sketch in the yellow rectangle by holding down left mouse button and dragging.
- Sketch must be one continuous line.
- You can release the mouse and continue again where you left off at any time.
- Click clear to start again.
- Save your file as PDF and DXF files. 

- Open PDF in adobe reader and print on A4 page with no scaling. It should take up most of the page.
- Put template on blank cam with center hole rectangular cam lock holes and arrow aligned.
- Trace profile to mark blank cam. Tracing paper may be useful to produce a clearer mark.
- cut profile with scroll saw or multiple cuts with a craft knife.
- Sand edge smooth and wax. 

- Alternatively you may save a DXF file. 
- Open this file in a DXF editor. Ensure 1 unit = 1mm. Center hole should = 9mm diameter
- Mirror vertically about the horizontal axis to get sketch the correct way up.
- Load DXF file into laser cutter or CNC router.
- Cut from 3mm MDF sheet.

- Place cam on the Skrippy sculpture such that the sketch on the cam shows correctly when viewed from the front.
- Push the 2 locking circles onto the cam shaft to fix it in place.
- Rotate the cam such that the cam arrow is pointing horizontally to the right cam follower and the followers slip into the deeper notches in the cam.
- Tighten or loosen the tensioning pins until the pencil tip sits in the small hole in the top right of the drawing plate under the paper. This is the approximate tensioning required.
- Pull the followers out from the cam notches and let the cam rotate clockwise to engage with cam. The pencil tip should now sit at the starting position of the sketch.
- Test the starting position by winding the handle to draw the sketch.
- If the pencil moves off the page then lengthen or shorten the cables by twisting the pins until the position is set and the hole sketch can be completed on the page.
- You may want to try slightly adjusted starting positions to get a better sketch.
