Excellent job! That box will be fun to show visitors to your home.

Amazing and inspiring work. Nicely done!

Nicely done. What bits did you use?

Thank you for your interest. I used a .25 uncut on the box pieces and a .125 with a .125 shank on the ribbon because I needed to cut .625 deep and a small pocket left behind. The .125 with .25 shank only cuts .5 deep so I used the smaller shank. I have never found a .125 x.25 that cut past .5 deep.

The Carvewright people have extra long carving bits. A 1/8" TBN and a 1/16" TBN. Both have a .25" shank and a carving depth of 2.125". They also have a pressed on sleeve for a 1/2" collet. The sleeve can be removed with the application of heat. Michael Tyler claims to have used the Carvewright bits in his Shopbot but has not mentioned the extra long bits. I have used them many times in the Carvewright machine with good results. Shallow passes are imperative.

I've been using these for 4 years when I nest close or maximize use of my hardwoods.
Likes a conventional toolpath, at 10K and around 2 IPS at 1/2Diameter pass depth...I've cutout everything from Teak to BBPly.
https://www.ebay.ie/itm/1-8-CUTTING-BIT ... :rk:1:pf:0 Not as smooth a cut as his .125"shank Downcut(normal CEL), but also just bought the same bit but with extended length that I've only used for a deep 3D roughing(River Red Gum and Big Leaf Quilted Maple). It says .675CEL, but my calipers say I'd try .8" feeling pretty comfortable, and it cuts Nice:)

It looks like you glued 5 flat (1/8" thick) sheets together to get the piece from which you cut the ribbon. How did you produce those 1/8" sheets? We've tried using a planer but sometimes the planer picks it up and munges it since it's so thin. Or did you use a drum sander? Or were you able to buy some type of veneer? Thanks.

Have you been using an auxiliary planer bed? https://www.woodmagazine.com/woodworkin ... planer-bed

Still no guarantee that the wood won't shatter (depending on grain structure) but it significantly reduces that chance. Also gets rid of snipe.

I use a drum sander to get the thin 1/8 layers. I do segmented vases and bowls so the drum sander is a plus for sanding the rings flat for gluing. The sander also will sand down to 1/16 pretty easily. If i did not have a drum sander I would probably just make my layers a little thicker and maybe only have 3 or 4 layers rather than 5. It would still look like ribbon. BTW I also have a DeWalt planer and no matter how fine tuned i get it i generally have snipe. Again the drum sander fixes that.

zaxis,

great job! in fact, I liked it so much, it inspired me to give it a try. the box is maple, and the ribbon it padauk and cherry
Thanks,

Ryan

What a great job. Your box turned out really nice. I am really glad that you benefitted from my post and gave it a try. I think doing things with CNC that is not all dedicated to carving plaques or making signs is always a good thing.

Great work, Ryan! The box is beautiful!

Very cool, Going to have to try that myself one of these days, those are really nice!

Thanks for the kind words. I love being parts of this forum, and this craft. seeing everyone's talent only pushes me to try harder, and do better.
