Once the main area has been done, make your way around the perimeter with the
disk sander, which will get into all the edges.
If the adhesive is bitumenbased, use a Surform planer and sand with a
disk sander. Alternatively, plywood over it and avoid the grief.
Q What grit do you use on your
disk sander when grinding down a recoil pad?
The tape will also later help to protect the stock when I'm grinding down the new recoil pad with a disk sander.
I just take the stock over to my disk sander and touch the newly cut end of the buttstock to the sanding disk.
In order to contain dust and dirt, I make extensive use of my shop vac by attaching it directly to machines that generate dust, like my
disk sander or bandsaw when they are in use.
