Step 2Cutting Pieces

Please chose which steps to follow based on the cutting option you have chosen.

Option 1 (Scroll saw and Drill)

Download and print the pdf pattern (please choose the file corresponding to your paper size) -A4 size paper ( '31A-(OAWR)-Scrollsaw Pattern(A4).pdf' )-Letter size paper ( '31B-(OAWR)-Scrollsaw Pattern(Letter).pdf' )(it is important to not scale the drawing while printing)
Measure the ruler on the printout against a ruler you trust, if they do not match the pattern has been scaled and you need to look at your printer settings before reprinting. If they do match up, onwards.
Glue the pattern to the acrylic sheet.
Drill holes

Option 2 (Online Digital Manufacturing; Ponoko) (this is the option I used)

Get a Ponoko account ( Ponoko )
Order the pieces here . (they are priced at cost ($11.47 Cutting cost + $8.28 material cost = $19.75 + Shipping (a warning Ponoko is currently only shipping from New Zealand so shipping is quite costly))

Option 3 (Access to a Laser Cutter)

Download the laser cutter optimized pattern (pieces are placed side by side and duplicate lines are removed)-( '32-(OAWR)-Laser Cutter Outline.eps' ) (.eps format)
Cut the file on your laser cutter.
