Step 3: Adapting monitor mount
I then measured the 60 mm (the width of the wood) from the pivot point and made a mark with a marker. I then drew a cut line using a square for accuracy and clamped it in the vice to be cut. Note in the picture I have made sure the line to be cut is as close to the vice jaw as possible to reduce vibration when cutting.
I used a hacksaw to cut the excess material off but if you have an angle grinder this will be much quicker. Once cut it is a good idea to use a file and remove any sharp edges left after cutting.
To allow mounting of the brackets to the wooden frame with the M8 bolts an 8 mm hole must be drilled. On the brackets here there was already a hole that could be widened. If there is not you will have to measure and mark the centre before using a smaller drill to make a pilot hole. Once you have a pilot hole you can then drill it out to 8 mm. I have a small press drill but a hand drill would to the job fine.
