Great to see you make your first post @Vadar. Can I ask what you are using the perspex for? It might help community members suggest the best tool for the job.
Let me also extend a very warm welcome to the Workshop community. We're pleased you could join us. Feel free to post anytime you need a hand or have a new project to share. I'm sure members will be more than happy to assist and provide information and inspiration for your projects. And please let me know if you ever need help getting the most from the site.
If you're using a circular saw to cut perspex, then you need to use a very fine toothed blade..otherwise it will crack..
