My first effort with rest machining . . .

I have a 3D file of St. Michael that I purchased on Etsy. As a retired cop, it holds special meaning for me and I have been wanting to carve it for a while now.

I spent some time this weekend trying to reduce the file size, both the physical size and carving size, to something a little more reasonable than 3.5 inches thick and over 20 inches tall. I got it down to 10 inches tall but almost fell over when the carve time was estimated at thirteen hours.

I heard about "rest machining" from PreciseBits.com and that it can seriously speed up a carve time. I did some research online and found that Legacy CNC, the makers of the GREATEST CNC ON EARTH, offered a couple classes on the technique. (Sorry, I got carried away there.) ;-)

I spent a couple hours watching videos and manipulating my file until I had it reduced to a seven hour carve time. Yep, from thirteen hours to seven . . . oh happy day!! I'm sure the file could have been made to carve even faster by a pro but I was pretty happy with my newbie effort.

So, here are some pictures of the carve in progress. I was not happy with my choice of bass wood. The bit would barely make contact with an area to be cut and a corner of the carving would just break off. I think cherry or maple would have been better choices.

Like I said, the wood simply broke in certain spots but it wasn't as bad as I thought it was going to be. There was a small piece of wood missing on Michael's chest, and one of Satan's horns was missing the tip and he had a finger missing on his left hand (poor Satan). :-(

Anyhow, here is a picture of a quick glue up fixing Satan's horn and finger.

The final tool path remedied most all of the issues. I still cannot believe how brittle bass wood is. I also cannot believe how "stringy" it was throughout the carve. I took a small, unused glue brush (somewhat stiff bristle) to the surface of the wood and knocked most of the stringy material away. I spent about ten minutes on it touching up areas with a fine grit sanding sponge. I will work on it tomorrow and hopefully make it worthy of some stain.

Turned out pretty good but I would definitely pop for some hardwood. I've found that I spend more time cleaning up fuzzies and chip-outs with softer woods and never get that smoothness we all want. |
I notice a lot of depth in the model and on most machines movements in the Z axis slow the machine incredibly. Try flattening the model out a bit and see if your time doesn't decrease dramatically. Watch so you don't lose too much detail in the process but you can sharpen up the detail before you start flattening the model. What program are you using to generate your code?

I'm going to get some cherry and see how it carves out. I actually liked the depth of the carving but I did reduce it down from over 3" thick to 1.5". I used Vectric Aspire to dial in the image and run the code. Here are a couple pics with some dark stain applied.

The stain really emphases the depth! Nice!
I'll have to check out Etsy! Would you think badly of me if I put a St. Michael plaque up on my front door? I'm sure most of my friends would get a good laugh, trying to picture me as a saint…

Please fill in the details Rob.

I'm assuming you started with a larger cutter and then did a tool change and picked up where you left off to machine the "rest" of the details with a much smaller cutter.

tools?
feeds?
speeds?

inquiring minds want to know.

I have since modified the file and achieved an even better carve time. I no longer have my Aspire summary sheet with the tools, feeds, and speeds. Once I carve the design in cherry, I will post the information.

That is fantastic. That would make me want to gild half the thing and the frame in gold leaf. I bet you could make some awesome baroque stuff with that.

Having a CNC allows for creativity even with the most basic of projects.

I bought a 1.5 horsepower DC3 mobile dust collector from Penn State Industries. I spent some time this weekend installing it and venting it to the outside. Here are some pictures of the finished install . . . before I ran the collection line along the back wall.

And since I had some extra casters sitting around and a giant CNC, of course I had to create a rolling base for the 15 gallon dust bin . . .

Designing the rolling base was super quick and easy using Aspire. I grabbed the Oneida logo from the web and did a quick conversion. It isn't perfect but, hey, it doesn't show and it gave me the opportunity to carve and work on my skills.

Now, if someone could please just do something about the humidity! For the love of Pete!
