Beginner Box

Post by mjohn » Tue Feb 19, 2013 8:34 pm

Here's a little collection of files for a small box & lid I built and found fun to mill plus it's perfect for testing new materials. Should be a nice beginner project for someone new and wanting to break into something beyond Hello World. I know how it feels to complete Hello World and some other words of choice and wanting to send something else through before you've learned the creation from scratch process.

The local home improvement store had some nice 1/2 x 1 1/2" Poplar on sale. This project requires about 2 1/2" of the stuff, but be sure to leave room for any clamps.

The gcode file and cb files are for a 3mm end mill bit. Start the bit centered on the edge of the piece, check in OpenSCAM (free) to see the path. There will be rounding on the inside of the box because of the bit and the lid is a little on the small side. When I designed the box I planned on lining the inside of the box. Just be aware of it! Feed rate is 200mm/min and plunge is 100mm/min which worked fine for me in soft Poplar. You may wish to slow this down, use CamBam or edit the GCode.

May I make a suggestion? Why not round the corners of the part of the lid that goes into the box, to match the rounding of the inside vertical edges of the box? That would give a better fit, I would think.

Nice boxes John! Thanks for posting.

I saw them on twitter and was going to suggest what cat said.

One of the things it took me a while to figure out was that all inside operations will have at the minimum the same radius as the bit used to create them. So an 1/8" bit will produce a 1/16" radius, a 1/4" will produce a 1/8", and so forth and so on.

Either way: For just getting your machine a few weeks ago, getting it assembled, and configured, then not only cutting a project, but publishing the supporting documents, and a brief explanation, I'd say it's a job well done!

Thanks CV and Edward, the design is certainly going to go through a lot of changes. I originally made it for gem sized wet plate photographs and the good thing is that anyone should be able to take the SKP file as a building platform and edit it to their own needs.

A rounded lid would look nice, but I'm more of a square edge kind of guy, eventually when I learn how to make separate roughing and finishing passes in CamBam I'll put a much smaller radius bit in there and clean the corners better. Maybe version 4. I'm running out of things to upgrade on my ShapeOko, so sitting down for an evening and reading the software manual may be in my future.

The machine part was easy, it takes awhile to get used too the open source hardware model (a shotgun blast of information, instructions, modifications) but once you get that, it's simple. Plus the whole build it yourself part really gives you a great working knowledge of the machine. Once I had it built I was very knowledgeable of what needed to change when I ran across a problem. The feedback of the two Y motors wired together was the most interesting. With that said, if I can build a ShapeOko and get such great results, anyone can.

Now learning the software is another step.

Why not just take a quick couple of whacks w/ a chisel?

If you only need it for things like this you could get a magnetic corner chisel:

You could mill a guide which would fit into the opening and ensure that it stayed square going all the way down.

Thanks Will, I have looked at them but they were always too large. That one you linked looks perfect. I may have to pick one up!

You might be able to pick up one of those corner chisels locally if you have a Rockler or Woodcraft nearby:

I don't think the chisel in a box has enough reach to manage the depth of mjohn's box.

The nice thing 'bout the Lee Valley design is that w/ the separate guide one could make a jig to hold the guide if necessary for boxes, as opposed to just the not so deep mortise for a hinge.
