I love how straight to the point (pun unintended) yet consise you are with this video. I was gifted a CNC router and had no idea what any of the bits did. Thank you for your help getting me going!!

Very informative you made things so much more understandable some of the other YouTube videos out there are just so confusing because they hop from one to another thank you very much you’ve clarified a lot for me

Congratulations, Hope you achieve your goals

For pocket cutting I've found a compression bit does great to give clean cuts top and bottom

Use a long ramp with your surfacing bit. Might help.

Damien, enjoying your videos because I just got my OneFinity (I'm just a hobbyist), and your conveying what you're learning feels like it's me learning too.

One thing I want to do with it is to resurface epoxy pours, or even just flatten some seasoned hardwood I have.

I read a horribly scary post on the the OneFinity forum about running the Makita at lower speeds with a resurfacing bit. The OP even says flames were shooting out of his router. I'd like to try to avoid that. Two Moose Design made a beautiful table and surfaced it with a Makita router and seemed to do ok.

I'm not that far along yet and am still aiming at things like cutting boards and personalized signs. I really liked your epoxy pour coasters too.

So my question is about flattening and what's safe, are flames really an issue, am I going to burn out my router sooner? (How did you finish off your coasters, sanding or cnc flattenting?) I can see batching things out with an initial cut, pour, then maybe a flatten and final cutout as a workflow.

A second question I have is on tooling costs. In the event that I muster the courage to actually try to sell my stuff, is there a way to calculate how long these different bits last? I've heard you say you're aggressive with yours, be interested to know if you feel like they dull faster or break more, etc.

Thanks,

Hi there, could you tell me please a good cnc and size to make guitars and necks, many thanks

To illustrate the differences between the V-bits you should do different V-carve examples. Understanding how the angle affects the details of a V-carve and the depth of cut are important things to take into consideration when selecting the appropriate V-bit.
