This channel is dedicated to the Guitars and basses that Luthier Mark Vinciguerra builds and repairs. We will talk about building and repair techniques as well as demo fresh built or rebuilt instruments. We will also talk about shop tooling and jigs as well as CNC and related tools and fixtures..... Including vacuum hold-down fixtures! We will even get into shop made pneumatic clamping and air bladder presses..... Plus anything else that may cross Mark's mind!!
