the stylus is fastened into a metal piece that he bought at the hardware store. he drilled holes in it and use small short screws to secure it to the wood piece the machine sits directly on. I used a non slip shelf linner to keep the machine from dancing around.
the white tape under neath is covering some wood blocks that are just sitting under to give the stylus a little more stability.
this photo shows the bolts with the nuts, be careful that they don't scratch the machine, I have a piece of velcro stuck to my machine in that area just in case.
