1st attempt at deep scratch removal on acrylic tank

  • We are currently upgrading MFK. thanks! -neo
Fantastic Job! Quick Question for you or anyone else who may know. I'm restoring a 1"thick acrylic tank, and I'm not sure of what type of sander to use. It seems as though the Orbital Sander is most recommended but does anyone know what speed I should get. I've found the Bosch 3727 rated at 12,000 OPM (orbits per minute).
However, it gets confusing when I see the makita 9227cx3 7" rated at 3000OPM but with higher amps (10) to the 3.3 for the Bosch. Anyway, can someone shed some light on this.
 
From what i know slower is better, don't want to create too much. More amps with less rpm probably means more torque

I'm the same way lol Funny how acrylic guys don't see the scratches anymore.

Go with a random orbit sander and if possible a direct drive version. Mine is random orbit but not direct drive so when I really push on it the unit bogs down and stops. variable speed is nice also. You want to go slow when sanding to keep in control and then turn it up when your buffing later in the project. Also go with the velcro type of attachment for quick changing of the sand paper or buffing surface you will spend more time sanding/buffing than replacing pads. It will literally cut your time in half.

Use that buffer you just bought and a lambs wool pad and buff that baby, it will come out. Be careful not to burn the acrylic, don't press hard just let the weight of the buffer do the work and keep it moving!

This is one of my quotes a year ago. WRONG lol If you do what I told ya above it will work but it will take a very long time. What I've learned in a year is you still have to put some back into it. Keep the surface wet and it wont burn. Start with a side panel first to get your confidence up.
