Cutting metal by hand is tiring and doing it accurately is difficult. Next up is a slitting saw arbor. This lets me use a metal cutting blade to accurately cut bits of metal, plastic and even wood.
Taig sells blank saw arbors, you just need to turn the end down to fit your blade. My blades have a 13mm hole so that is what got cut. No problem cutting stuff now! The big stuff of course still gets done on the 4×6 horizontal band-saw .
My saw blades come from CTC Tools, a great online shop for quality tools.
