Multiple blade bow saw - uses conventional blades set by distance pieces between segments secured by bars passing through holes

摘要

The multiple-cut bow saw uses a number of conventional saw blades set at the desired distance apart. The individual blade segments can accommodate the blades, and the desired interval can be obtained by inserting distance piece (6) between the segments (1), these being secured by a bar passed through holes in them and clamped together in a packet. A single block can be used instead of the distance pieces where fixed intervals are desired,t he individual blades being secured by a through steel bolt. The design allows even tensioning and easy changing of the blades.
