    Brady,
    Again I thank you for being so generous with your time and knowledge. This is exactly what I needed to know, boiled down to a couple of paragraphs. I spent hours rummaging around in the TSB...

    Rhino --> VCarve Import

    Doesn't seem to be any penalty for setting the resolution even finer, AFAICT, other than a minor file size hit. At .0005" I don't think I...

    Facets in Rhino --> VCarve Import

    First time I've tried importing a Rhino 3D model into VCarve, a simple form for vacuum molding. In Rhino it's a completely smooth NURBS object. When I brought it into VCarve, it looked like it had...

    Thanks, Brady. I'm slow and clumsy with a dial indicator. I got a lot of practice on my big table, since I had to swap the spindle far too often due to dumb mistakes. I found that I could get...

    You're kidding! Apologizing for giving me so much information (and time) without charging even a nickel for consulting? On a holiday weekend? It's why this board and the folks who support it are...

    Brady,
    Big thanks, O Vacuum Sensei! I'll revise my plan. "Easier to seal" is good - my design certainly wasn't that. I was hoping a tube of removable sealant would handle it, but that would be...

    Brady,

    Would you please explain why a top routing is bad? I'm not knowledgeable about fluid dynamics, but I have read that fewer sharp bends is better. This design has no bends at all from the...

    For sure. I need to measure where the collet nut and spindle are relative to the cut volume boundary with my lowest likely cut scenario. Then adjust the outlet block to be clear.

    I just purchased a 2015 D2418 that sat unused for the past 2+ years. There are rust speckles on the tops of the V rails. Can I just give it a light rub with oil and steel wool, or is there a better...
