Ok, so I am trying to find a solution to sanding the edges of MDF. The thing is the edges are in funky shapes like stars, butterflies, guitars, and such.
I bought a harbor freight spindle sander to try out. Using the 80 grit takes far too much material off and I will be buying a set of 150 grit ASAP to try. (the edges are sealed with Kilz) The vibration on the spindle closest to the table is about .008” and on the top its about .014” (jumps to .020” at times). I am curious to know if higher end spindle sanders have far less runout and also how much runout is too much? As you can tell I basically have no experience at this and I don’t want to be stuck with a $130 tool that does not do a professional job and have to spend $500 on a real OSS.
Are there other solutions to sanding odd shape edges of MDF? Hand sanding for a complicated unit takes 30 minutes! There are a few inside corner radiuses of 1/4” and I think I will take a small dowel cut a slot thus making a super small flapper sander. IDK.
