I am back home after being gone for a week and a pile of projects awaits.
- The Railroad group wanted a HO gage 3D print of an A10 for the airbase on the layout. It is printing right now. I had to do it in 2 parts, since it was larger than my little 3D printer could handle.
- My wife’s sister wanted a couple end-grain cutting boards (Texas sized 19” x 16” x 1.5”) to give as gifts. I am trying a four-wood design (Maple, Cherry, Sapele, Walnut) using a couple different designs. Hopefully, they will come out as I envision them. Boards like this can easily cost >$200 retail.
- I still have a few gifts of my own to finish as well.
While working on that I thought I’d attempt a CNC design using 2 different bits. A 1.5mm bit for the course work and a 1.0mm bit for cleaning out the contours of the letters.
Here is the design I am trying to produce:
The first pass with the 1.5 mm bit will take out the bulk of the material for the letters, using a 2D pocket milling operation:
Since this design is small (150 mm x 150 mm), it leaves quite a bit of the letter details uncut. So, another pass is required. This one will only focus on the 2D contour of the letters.
This gets into every nook and cranny that a 1mm bit can reach.
Once this is milled, the plan is to paint the letters in the appropriate colors (e.g., stars yellow, letters black) and then sand off the top millimeter or so. This will allow for the letters to be painted (including the sides) and yet have the wood surface show unpainted.
I’ll have to do another post when it is all done and show the finished result.
