Vinyl cuts easy. That's a problem because it cuts so easy it can be difficult to control the blade. Use a #3 or smaller blade and turn the saw speed down. Make sure you apply blue painters tape to the record as shown in the pattern. Take your time. You could also try stack cutting two records. The thickness of the two would help you control the blade. Make sure they are lined up and taped together securely.
Another problem is that it's difficult to turn the record on the saw table while cutting. I just slip my fingernail under the record and lift up just enough to get hold of the edge.
I also had to slightly enlarge the center hole for the clock movement to fit. I used a clock movement designed for 1/4" thick clock face. I used the white side of the hands so they would stand out better.
