I am cutting clock parts and I use a thin double sided tape used and sold for hold down small engraving parts, it works really well.
http://www.pantograph.co.uk/pdfs/accesories.pdf there is low tack and high tack depending on what you need to hold down, far quicker and easy clean than using super glue and blue tape.

When I design a sheet of clock wheels to cut out I put a strip of D/S under and also cut out the centre holes first and drop a screw in to hold each in place whist all the crossing cut outs are done then follow up cutting the disk out I only use tabs for parts with no screw holes.
