Spud cutter

Mounted directly to the barrel, or kept as a sperate utensile, this is used to cut produce to the diameter of the barrel.

It is made by reducing the outside diameter of the barrel until you form a sharp edge. In combustions, is recomended that you add an inner chamfer to your launcher; this cuts a tighter fitting projectile, which acts a bit like a burst disk, allowing the pressure to build before projectile starts to move.

However, there are defishencies in the typical PVC 'cutter, mainly that it is a relitivly soft material and therefore can neither be sharpened very well or hold an edge. Many have attempted to counter this by:

• Serating their cutter. (one, two)
• Making them out of steel. (at risk of promoting my own product...)
