First parts coming off the CNC machine

Last night I successfully ran my first “real” jobs on the CNC.  One was a jig to hold a number of PIcoKeyer-Plus cabinet end panels, which came out perfectly.  Then I used that to actually mill an end panel, which also worked exactly as I had it set up to do. Today I’ll run a batch of end panels, and set up a jig to drill tiny speaker grilles in the cabinet tops.

It’s almost scary how perfectly the stuff is coming out.  I’m still learning about tool selection.  For example, I assumed a 4-flute end mill would be best for doing the cabinet because it will produce a smooth finish.  However, I think a 2-flute would be better.  I’m also learning how much material can be removed, and how fast, to get the best results.  Speed control for the spindle would be good, but for now I’ll settle for just getting the stuff done!

Update on the CNC mill

I’ve now spent a few days’ worth of free time working on getting the CNC mill set up, tested and adjusted. I finally got access to the more useful forums at Lumenlab’s web site, so I have some additional measurements, adjustments and run-in to do. All in all, by the time I finally get the spindle and am able to do some real work, I should have things set up pretty well.

I’ve still got some stuff to do with getting the wiring cleaned up, and I want to get the motor driver board and power supply mounted into the controller PC case. For the time being, though, everything is going well. With e Dremel flex head temporarily and not-too-solidly clamped to the tool head, I was able to do some test cuts on a scarp 2×4 and will do some more testing after adjusting for backlash and tramming (squaring).

I’ve got a LOT of potential projects lined up. Of course the primary use for the short term will be making the holes for PicoKeyer and other cabinets. I want to make a tabletop stand.cabinet for my Nixie tube clock. I want to do some engraving and see how well it does with relief carving in wood, with the idea that I might be able to make some plaques and decorations. There will be some bits and pieces for the Harley also, starting with new bushings for the removable tour pack kit.

A new toy – err, I mean, tool!!

For the past couple of days I have been working on assembling and figuring out the wiring and setup for the newest tool in the tool box.   OK, it would be a BIG tool box.   I’m just waiting for the rotary tool heads to arrive so I can do some real work with this sucker…
