I decided on using 2×4’s for the mounting, but their rounded edges needed to be removed to make a solid mount. Time to use the beast! This is my 13″ Rockwell planer that weighs an ungodly amount, but that weight makes for a very solid machine. Also a handy machine if you want to make bedding for hamsters.
I cut this out on the table saw with the blade height set to the depth of our groove. You can space the cuts at about a 1/4″ and then snap out the remaining scrap. A few passes through the saw and I have a piece set up to be easily cut out with a jig saw.
The cross-piece should be cut to 1/8″ less than the inside width of the cabinet. This allows for a little play, so it’s easier to install. I attached the monitor mount to the middle of the cross piece, and then secured it with 4 screws.
Then comes the most difficult part. Where to attach these in the cabinet? What I should have done was solid modeled this whole thing and then determined dimensions from there. In reality I got out my ruler and put one screw in the u-shaped mount and just roughly attached it to the inside of the cabinet in a spot that “looked good”. I made sure that the mount on the other side was in the same location (a huge pain!), and then I temporarily mounted the monitor. I rotated the mounts until I like the position and then attached more screws, solidifying the chosen location.
