Finishing an edge on plexiglass...
(1/4) > >>
Sinner:
Does anyone know of a good way to finish a drilled or cut edge on plexiglass?  The edge is kind of sharp around my trackball, and I'd like to clean it up, but I don't want to start sanding, if this will damage it...
Thanks...
SUB ZERO:
A "round-over" router bit will work  :)
Stingray:
Router bits will work on plexi, or is this a special plexi bit? Never occured to me to use my router on plexi, I assumed it would crack.

Kewl...thanks...I used a flush trim bit to route the outside shape of the plexi...I will see about getting a rounding bit and give it a try...thanks for the info...

Why not do it the old fashioned way.

Sand it with 220 grit silcon carbide paper and then attack it with a buffing wheel attached to your  drill.

I made a keychain in grade 7 made out of three layers of plexi glued together, cut with a hand jigsaw.  All we did was sand the edges then use a bench grinder with a buffing wheel to polish the edges.  It came out shiny and smooth.  That was way way way back when swatches were popular, and the guys would all show up for shop class with seven watches on their wrist, polishing the lens on the girls' swatches.  Actually we had co-ed shop class, but you could chat up the girls who were in home-ec that half of the year by offering to buff their swatches.... oh that sounds worse than it should.

But I digress....

So why make it harder than sand it and buff it?
