    Schematics and Circuit Board layout with Fusion 360

    Do it in the oven! When ordering the PCB also order a stencil. Use a squeegee and solder paste to populate the copper with solder paste. With tweezers and a careful touch, place the SMT components gently on their pads. Then in a toaster oven set for approx 220 degrees, bake that cookie for...

    Carbide scraper tooling.

    I'll save you the trouble of measuring the inserts. Making an 80.9mm fly cutter will be a challenge though!

    Boring small holes in drop forged wrenches.

    I had a similar problem, drilling 3/16 through a hardened shaft. None of my bits would take a bite, even a solid carbide end mill, but HiRoc drills made by M.A. Ford did the job perfectly. They require a very rigid setup, so don't try it on a standard drill press.

    Product Anchor Lube...

    No, it's not for oiling anchors.... I came across this stuff at KBC, and I've been using it exclusively over the past two weeks instead of the usual cutting oils. It is a creamy, water based goop that stays put and doesn't fly off the work. I like the fact that when tapping deep holes it...
