There is a really good reason for these height measuring devices.What great ideas!

Ha - I focused on the HVAC return vent. On YT I've been bombarded by ads for these lately.
I recommend that you put the height of the screw for the keyhole on the back of the ruler. It will make a re-install quicker and easier than matching ruler lines,I machined keyholes in the back of the “ruler”, the bottom is 7-1/4” AFF. The 7-1/4” cutoff (to rest on the baseboard) puts the 1’ mark 1’ AFF.

What did you use to create the lines? My lettering skills seemed to fall short on the number “2”.All those nice, straight and parallel lines would have had me kill the project.

I’ve owned the CNC for 4 years and the Shaper Origin for about 6-7 years. Some months we’ll process 120+ sheets of material for cabinet fabrication, other months it may be as few as 10 sheets.I guess I would have painted the lines.
I would apply a 3/4” wide piece of masking tape horizontally. Then a 1/4” wide strip adjacent. Then repeat over and over again.
When the “ruler” was fully covered, I would peel away the 1/4” strips revealing the area to paint.
Add a lengthwise strip of 3/4” tape to limit the line length.
I would have to take particular care to make sure that the strips of tape were all perpendicular to the length, but it should be manageable.
I would not invest in any CNC equipment for that project.


I was talking about if I were to attempt that ruler. You already had the Origin and it made sense to use it. I was only saying how I, not a CNC or Origin owner would approach that project.I’ve owned the CNC for 4 years and the Shaper Origin for about 6-7 years.

There is more in the cost of the piece of wood than there is in the CNC time.
There are things the Origin out shines the CNC on. The pockets for the pulls/knobs on these two jobs were done using the Origin. The design was done on tool, stops are set, one set up per size of face.
