Now that you’re done with the RT (Rotary Tool) treatment, it
is time to move on to the Elbow Grease application. The goal of this entire process is to reduce
the “tool marks” in the material to zero over many steps. Get your rat-tail files out and go over all
of the edges and contours you just hit with the RT. The action of this process should resemble
someone playing scales on a violin. Your
cut and draw stroke should slide along the edge of the piece and then your
angle of attack should adjust slightly as you repeat. Start will a little pressure and increase as
you feel comfortable. If you add too
much pressure and pause for a moment you can notch the edge and have to go back
to the RT to smooth it out.
You should see the small “lines” or tool marks
that the RT left start to blend out. Pay
careful attention to the acute inside corners of your project and use a smaller
file if needed.
Next up, we’ll get to work with those foam sanding blocks
and maybe start to unlock the mystery of the Nomex Glove.
