    Expensive to do
    I have access to all but the vacuum chamber and polisher. However my a few of my suppliers will cut to size and diamond polish if required. Just need to find or make a Vacuum chamber!

    Thanks for sharing...

    EF-200 polisher is over 10k new.

    I've seen used one for sale locally not long age for 5K asking price but since I don't do much of that type of service I passed on it.

    See if you can locate one on ebay or CL.

    There are some smaller one's Scotty, for flat edges they start at about $7k but the one used to do that award block was $40k. The cutters are really expensive 6 tip diamond, decent one was £2k, any sign of a chip and it throws the balance out leaving a rubbish surface or ripples
    You did what !

    Diamond edge polishers are definitely nice. Darren, - I have done bubble free mitered edges (cast acrylic, no heat when machining, etc), but the labor is insane. I used 2 part from a double tube cartridge so it was bubble free coming right out the spout, and used the taped edge method to then "fold" the miters together. The hard part is reaching inside the box to scrape off the squeeze out prior to demasking (gotta leave masking on, which is tough, because you want to see the bubble-free joint get filled adequately). If I were to do it again, I would use clear PET tape (packaging tape) on the outside faces at the miters. The other hard part is gravity stresses or other stresses like diagonal clamps for squaring, which can ruin and open a bubble-free joint, hence the 46 degree miters to allow adhesive flow.

    Why don't we have a thumbs up feature on this forum??? You deserve some for that.
    Chinese 6040 by NiceCut. Originally 60 Watt upgraded to 150 Watt.....I thought I had pretty much every problem in the book of laser cutting. It turns out that there is a set of books.

    Acryfix Versatile. order online at acryliteshop dot com. Sorry, forgot about the mix nozzle stuff. I got that from McMaster - Weld-on 42 I think, which now is ISP. The gun is pricey, but now I have the gun.
