From the shop
I write down the setups, abrasive choices, tracking adjustments and maintenance checks I use at the grinder.

Filed by what you are doing at the machine — grinding, sharpening, heat treat, maintenance, or running the business side of a shop.
Vibration comes from parts that are out of balance or loose against each other. Here is how machined aluminum wheels, machined tracking parts and a precision-cut chassis cut it on the Torus 2×72, and what that does for your blades.
A belt that walks off the wheel is not bad luck, it is geometry. Here is how tension, wheel alignment and frame flex interact, and why a CNC-machined chassis holds tracking that a welded frame loses.
Going pro changes what you need from a grinder: repeatable bevels, faster stock removal, and a machine that runs every day. Here is how the Torus 2×72 supports a knifemaking business, and how to check that grinding is your limit.
Sharpen, shape and polish on one machine. Here is how I use the 2×72 for all three: the belts and angles for a working edge, the passes that shape a blade, and the progression that brings up a polish.
Thin stainless blades warp in the quench unless something holds them flat while they cool. Here is how aluminum quench plates work, why I built a vise to clamp them, and how to use both for straight blades.
Aluminum recycles forever, resists corrosion, needs no paint, and ships lighter. Here is why the material I build the Nova from is also the lower-impact choice for a shop, and what I do with the chips.
Parts machined to the same drawing fit the first time. Here is how CNC aluminum components make a 2×72 faster to assemble and set up, why I assemble and test every Torus myself, and what that means on your bench.
A 1x30 will sharpen a knife. A 2×72 will build one. Here is how belt length changes heat, belt life, power and attachments, and how to decide whether a 2×42, 2x48 or 2×72 is right for your shop.
A machined aluminum grinder looks like it came out of a machine shop because it did. Here is why the look is a side effect of the precision: flat faces, true holes, no paint to chip, easy cleaning.
Belt speed, grit and horsepower are one system. Run a fine belt too fast and you burn the edge; run a coarse belt on a weak motor and it bogs. Here is how I match all three on the 2×72.
A 2×72 sharpens a chef knife in two minutes and a mower blade in five. That is a business. Here is how to start a sharpening service around one grinder: setup, belts and angles, pricing, and finding customers.
A 2×72 can speed profiling, beveling, handle shaping and sharpening, but it is one route, not a requirement. Here is what it adds to a knife shop, what to compare before buying, and where another tool may still fit.
