Perfect Deep Wood Inlay - How to get perfect inlays with a CNC machine using straight bits (no gaps)

Video Description

Hi CNC woodworkers! This video is how to get perfect inlays with a straight bit. Using a straight bit is required when you want a deep inlay; something greater than 1/2" thick and up to 1" thick. You may also want to do a deep inlay in order to have the design on both sides of the wood. I cover a lot of detail: why to do them, how to properly work around vector design limitations, speeds and feeds, leaving material, and inlay tolerances. Then I'll discuss what parameters to change in two of the most popular CAM/toolpath generation programs: Fusion 360 and Vectric VCarve (also applies to Vectric Aspire). You can skip over to the chapters that discuss the program you use. I'll quickly cover how to make an inlay in each program, but this video is more about how to find the right inlay parameters, and not how to use VCarve or Fusion. https://www.facebook.com/groups/corbincncwoodworking - Corbin's CNC Woodworking Group on Facebook! The alternative way to do an inlay is with a v-bit, and vcarve the inlay. I prefer VCarve inlays when doing a design that will only appear on one side of my project. * VCarve Inlays with Fusion: https://www.youtube.com/watch?v=Wb93CZbNeWs * My email list / newsletter: https://www.corbinsworkshop.com/newsletter_subscribe/ * Amana bit I disucssed and use: https://amzn.to/46AFCKY * Bit information: https://www.amanatool.com/45611-k-solid-carbide-15-degree-engraving-0-005-tip-width-x-1-4-inch-shank-signmaking-spektratm-extreme-tool-life-coated-router-bit.html Note that this bit has a slight taper; I set it up as a 1/8" bit, and assume no taper. One thing I didn't mention is that this slight taper helps a tiny bit with the fit on these deep inlays. If you use this bit, be sure to push your inlays together from the sides you carved on; this should be no problem, if you follow my instructions on leaving a "skin", as you won't be able to get it wrong.

PS: the inlay shape is the top of a pineapple to give it a tropical feel. Thanks everyone!
