Kingman Spyder and -Clone Halfblock Conversion

This set of files can be used to halfblock your spyder compatible stacked tube blowback marker. This has been designed for a marker that has already been converted to pump, so I can not guarantee it'll work with semi.

Clamp on the cutting guide and hacksaw away. Leave a bit of material when using the saw and clean it flush to the guide with a file. That way you will get a much cleaner finish surface and the guide ensures your final result is square.

The marker I converted is a Protoyz Speedster (rebranded by umarex. As far as I'm aware its body uses the same extrusion as classic/standard spyder, but I can not guarantee the cutting guide will fit.
