Cut out the logo of my mountain. Pop can is for scale. Took just over 30 minutes to cut this, at 75 in/min, it's 0.25" deep, I did it in two passes of 0.125"

Nice work Twizz! I've been dreaming of doing this for quite awhile. When you get to it I might be able to help you with a 3-D profile of the Snoqualmie Area. I am a GIS Analyst here in Oregon and have all sorts of access to data and the software to manipulate it. What sort of format would you need it in to work with your CNC code? Cheers.

Thanks for the offer to help Cal, but I think I've got what I need.

I was able to use the data from the link Mike posted a few posts back. I've now got the 3D model in an IGES format, and it looks pretty awesome... but it's so detailed, when trying to generate tool paths it crashes. It doesn't help that my shop computer is pretty old/crappy

One of these days I'll buy myself a new computer, but I'm too cheap (ahem... didn't I just spend way too much building this machine??)

Cheap!? You're a ski builder. You already have many paychecks devoted to this bottomless pit :-D btw- awesome cnc machine.

I can just picture the "Ski Builders Anonymous" meetings...

My name is Sean, and I'm a ski builder.

Nice build! Did you do all of the machining yourself on the cnc grizzly?

I made a motor mount adapter for the z-axis to mount my stepper motor to the ballscrew thing I got (which had a smaller mount), and I made these setscrew adapter things that bolt onto the x-axis timing pulleys. Both of those things I did machine on my CNC grizzly mill (made by a CNC machine, for a CNC machine!

)

Everything else was cut by hand with an angle grinder, band saw, drill press, or hand drill, except for some of the larger/more critical parts, which I had laser cut by some place.

Twizz,
I'm blown away. That is very impressive. Love the use of steel. If you're going to be carving away in bamboo, you just did it right. Kudos.

Finally got the gcode worked out for the Snoqualmie Pass terrain.

Cut a test piece out of normal pink insulation foam. This was small, about 12" wide, took about an hour to cut.

Next I want to glue up a bunch of layers of light colored wood (maple maybe?) with black epoxy, then machine this on that so the layers form topo lines. It will be 2ft x 3ft, that I can mount on the wall

Very nice machine! I am still working on mine...

Cheers, Christoph

Wow cool! Make a mini 3d relief on a pair of skis.

Oh no... The ideas start flying... I could machine a long chain of mountains (real ones or not), say 1/2" tall, out of similar foam and then glue that to the top of a pair of skis. The foam would add basically no weight, and wouldn't change the stiffness of the ski at all. I'd want to seal it up with something, epoxy or something, and it would get torn up real bad after just one day... But the novelty of it would be pretty cool!
