Hi everyone,
I’ve seen others using a curved platen on their edge sanders and have wanted to try this technique. I am a at a bit of a loss as to how to go about actually doing it. I was hoping to hear how others have achieved mounting the curved platen to the sander. How do you calculate the belt length, and do you have a system to interchange different curves to the sander? Lastly, are there any tips about the material used to make the platen and is it important to use graphite paper to insure smooth belt movement? 
I look forward to your tips and answers. Thank you for your time.
