I want to make myself a super bread-slicer. I bake all of our family's sandwich bread, and it's a real pain to slice the loaves straight and even, and I'm not going to lay out thousands for an industrial mechanized bread slicer.
My plan is to build a rectangular frame to hold 20 or so hacksaw blades, all spaced one desired-thickness apart (10-15mm?), so I can slice a whole loaf with perfect regularity all at once.
For one end I can cut narrow slots and drill a hole to slide a pin to hold them all, or maybe just hold the holes with screw-in hooks, but to properly tension the other end, I need a whole pile of hacksaw tension pins. Probably have to replace wing-nuts with hex nuts because wing nuts would get in each others' way.
Obviously I can buy hacksaw blades cheap in bulk, but where can I buy tension pins in bulk? I can't find anything online at like grainger or mcmaster-carr, but I don't really know my way around this space. Obviously I don't want to buy 20 hacksaws and throw away all the perfectly-good frames.
Any ideas would be welcome, as well as design alternatives (it would be nice if the design had a thickness adjustment, I'm thinking flat metal bars with wingnut bolts holding the corners together, but the hacksaw blades need to be able to remain parallel as it is adjusted)
Another idea comes to mind, maybe hooks with machine-screw ends, then the threaded parts could just feed through the frame and secure with nuts? Do they make hooks with machine-screw ends rather than wood-screw ends? But really hacksaw tension pins are the "right" tool for this job...
