Description in audio. This my digital depth gauge system. I use it as a digital depth gauge 99% of the time. But the sine bars are really useful especially on thin parts in a vise. If you do much surface grinding this is a must have for measuring part height from the chuck. All hardened, ground and lapped A2 tool steel. The case was from an insert cutter and I just made the foam insert. I also made all the depth rods and I used a interesting system to make the rods Gage block accurate in the grinder. Don't hold your breath for the video on YouTube but when I do I'll show how do I ground the rods.

Description in audio. Lens wrenches for tightening cylindrical parts without marring the surfaces. On the wrenches on the indicator, that chunk of neoprene in the gap springs them open so they go on easy but compresses to allow gripping.

Amazon selling some Knipex items at below factory cost. Chad's Tool Box sent an alert letting his customers know about these crazy deals. That is some awesome customer service when you send your customers to a better deal.

Are you kidding? That's the closest thing I have ever had to a viral video and never thought this one would be it.

Description in audio. Bright boy or Cratex sticks are the magic sauce in the glossy finishes you see on my parts. Especially important on heat-treated parts to do before heat treat as it is immensely more effective than after heat treat. Cratex medium grade I find to be the best all around. Fairly expensive but last a long time. You can cut them with a utility knife and grind them to shapes with a bench grinder.

Description in audio. Super slow hand powered spindle drive to remove chatter from large face of engagement tool situations. Chatter often occurs just as you slow down to hit size. By switching to hand power as soon as chatter occurs you can usually save the day.

Fusion 360 model of pulley grooves and Cam toolpath. Posted to Tormach Path pilot control. Cut a test piece and section it for crisp image on the Optical comparator. Inspect the form on the comparator for radii, angles, spacing, etc. Executed on the real A2 part. I'm old enough to have done a lot of G-Code programming by hand including the trig (calculator not abacus) before mainstream CadCam existed. So I think I appreciate this technology more than the youngsters. Big shout out to John @saundersmachineworks since his content was responsible for me buying the Tormach lathe and Fusion 360. Thanks John for straightening me out on that turret number issue. The number of hours I had spent spinning my wheels on that is embarrassing. 😶

Description in audio. Hex handle enables grinding the three facets of a triangle scraper very easily. In this case .25" dia ultra micro grain carbide. The most dangerous tool in the Machine Shop, not kidding.

Description in audio. Nice two sided container to allow moving a part from one side to the other as you complete a particular operation on each part. Those grinding quills I shared in a previous post had:
Saw, turn front half, turn back half, mill flats, drill holes, abrasive brush deburr, clear thru hole burrs from cross drilling, Ultrasonic wash.

Description in audio. A beautiful Mahr Millimess 1 Micron indicator. Believe it or not, my first indicator of this style. Probably because I've had electronic gage heads forever. Never too old to try something old!
