Newbie question. I am trying to make a sign for a campsite using the “National Forest” font. Through trial and error, plus some helpful people on the Shapeoko beginner Facebook page, I have successfully converted the word “Recreation”, typed in the National Forest font, to vectors, using Affinity Designer 2, and have successfully edited the vectors in Carbide Create to link the individual letters into a word. Now I am experimenting with various bits to engrave the letters into some relatively hard cypress lumber I have on hand. The capital letters are being carved 1.5 inches tall and the small letters 1 inch tall. The photo below shows my attempt with a 60 degree V bit, carved in a scrap board of maple, which I didn’t care for. Depth of cut was 0.15 inches.
The next image is a screen print from Carbide Create of the tool paths for my next trial in a piece of cypress. The top path used a 1/8" Amana downcut bit with zero offset, simply tracing the lines. The bottom path used the same Amana bit with the offset direction “inside/left”. Depth of cut for both trials were 0.10 inches.
Below is a photo of the actual production, using cypress, on my Shapeoko Pro with the 1/8" Amana downcut bit.
Of these two I like the bottom one best but I would like to see some of the extraneous material in the path of the writing removed (see the R for example). Should I run this file as a pocket instead of a contour? If so would it make sense to cut the outline of the letters with a 1/16 downcut bit and then clear the pocket with a 1/8 upcut bit? Any other suggestions?
I’m still a novice trying things with wood from my workshop scrap pile in order to learn processes and how different bits perform under different situations.
