Because we do a lot of
tooling, model building, and finishing at BVM, sanding is an everyday
experience for us. We have found that using 3M Adhesive backed Open
Coat, Pre-Cut sandpaper in 2 3/4" wide roll format is very handy.
You can acquire this product
at automotive paint stores in a variety of cutting grits. Primarily,
we use #80, #180, and #320 to do 90% of the sanding chores.
It is good practice to use
flat blocks, round rods, wedge shaped blocks etc. before proceeding to more
flexible pads for final finish sanding. Make the sandpaper mounting
forms as needed for each job. The photo shows a sampling of handy
tools. You can design the size of the tools for efficient use of the
For simple hand sanding, you
can just fold the sandpaper on itself and cut as shown.
Hotel plastic key cards with
the sandpaper applied to one or both sides will have many applications
because they are thin and a bit flexible. Trim off the exposed end of
the card. This tool with #180 grit paper is excellent for initial
sanding of resin/fiberglass cloth covered wood wings and tails.
The more you work with these
3M abrasive products and custom made sanding tools, the easier and faster
your sanding chores can be handled.
