Brady Watson scanning service

[cr2]

A while back I got Brady to scan a silver dollar for me. The resolution of his scans is incredible, and I used the reliefs on a small (3.5" diameter) case for a silver dollar. The case is made of Grenadilla (African Blackwood).
Speeds and feeds used:

1/8" ball, 15000 RPM, 20% (.025") STEP OVER, 60 IPM
1/32" ball, 15000 RPM, 35% (.011") STEP OVER, 60 IPM
1/64"ball, 18000 RPM, 10% (.0015") STEP OVER, 25 IPM

Here is a short video of the 1/64" end mill making the final cut:

Nice work and a good idea for the case.

Nice edge cut pattern. Very well done.

I just find humor in seeing a big machine spinning such a tiny bit, I'm blown away that the end does not snap off from minor pressure.

You used a lathe to get the side design?

Really nice work. Thanks for sharing.

VERY nice detail Charlie!
Whose 32'nd and 64'ths are you using?
Absolutely agree with the details on Brady's scans:)
Wonderful work on your part!!

What a great idea for displaying the real thing. Good job to both of you.

Thanks a lot guys. Yes, to engrave the edge design I used a 4th axis indexer. Scott, I usually use Atrax end mills from Enco, but they only go down to 1/32". The 1/64" end mill is from Harvey Tool. I had two of them and broke the first one immediately at 45 ipm. Then I slowed it down to 25 ipm and had no more problems.

Beautiful work
What machine do you have - Desktop or a conventional Shopbot?
that is some of the finest resolution carving I have ever seen.

Thank you Bob. I have been reading this forum since 2006 when I got my first cnc router. Actually I read several different cnc forums every morning. My reason for posting this was a recent thread about cheap 3D scanners. I have used Brady to scan items before this, and I thought it would be a good time to show off the quality of his work and the results that his scans make possible. It just so happens that my current machine is another brand, but I have learned a lot on this forum, and I am grateful if I can give something back.
