3DSurface

DigitalTooling

Then I went CNC, and I started noticing a lot of that tooling wasn’t needed any more. Though I might like to…

Old rusty wrench, isolated on white background

It’s a real heart breaker to pull out a tool you haven’t looked at in a while and discover it has rust. Nasty stuff. I live within sight of the ocean, so my shop is particularly susceptible. My answer is to apply a rust preventative called “Break-Free” when I first get a tool into the…

The tide is starting to turn and we’re actually beginning to see some manufacturing being “reshored”–it’s coming back from having been “offshored.”  There are a number of disadvantages to offshoring that it has taken hard-won experience for many customers to realize.  Shouldn’t you be aware of where the sweet spot for offshoring is and make…
