Products makes a line of Perma-Grit tools. Most are round or triangular file-like devices but they
also sell flat sheets of thin steel with carbide brazed to them. The flat sheets can be bonded to a
board and this makes a great float-sanding device. We suggest you buy one of each of the Perma-
Grit sanding tools and four of the sheets.
Sanding Blocks
There are many times when you have to sand in weird places. The simplest thing is to make a
series of sanding blocks. These are usually rectangular pieces of wood with strips of sandpaper
glued to one surface. To float sand the wing, you will need a long smooth board with a fairly wide
piece of sandpaper. Ordinarily, you will find that the best solution is to buy the 6”x48” belts used
for stationary belt sanders. Cut the belt—it is a continuous loop—and glue it to a planed board of
the same width. Use contact cement to glue the paper. The same hardware store that sells the
belts will also sell a contact cement used to cement sandpaper to disc sanders.
For smaller places, you will want a series of standing sticks. You will need a number of different
sizes depending on what you are trying to do. To finish out the longeron cutouts in the fuselage
frames, you should have a sanding stick about 20x20 in cross-section and long enough so that one
end will rest in the cutout of the next frame to align the stick. For the sandpaper, you can use
normal sheets of sandpaper and cut them to the required width.
Gil-Bilt Power Tool Kits
For those who would like to save some money and take on another kit, you can make your own
power tools. See the entry for Gilliom Manufacturing in Appendix A. There is a wide
assortment of tools from band saws to lathes.
Laminate Trimmer
A laminate trimmer bit in a router is very handy for cutting birch plywood after gluing. It cuts
right up to the edge of the wood underneath, follows curves and does not splinter the plywood as
saws do.
Offset Screwdriver
There will be many time when you will want to get at a screw in very close quarters. An offset
screwdriver will take care of this. Available in Phillips head or the normal flat blade type, an
offset screwdriver looks like any other screwdriver except that there is no handle—instead the
shaft is bent at 90° on each end, and the normal screwdriver tip is on each bent end. When you
get to the electrical kit, you'll
have to have one since there is no other way to get to the screw
terminals of the circuit breakers.
Moisture Meters
Several companies make moisture meters. These are handy when you are skinning the airplane.
If the plywood is too dry, you will have a wavy skin. The best type of meter has a dial or digital
indicator. You do not want the type with LED indicator lights. Also, purchase the type with
small pins for electrodes. The larger electrodes (medium-sized “nails” mounted on a hammer) are
used for sawmills.
If you would like to save some money and spend some time tinkering, you can make your own
moisture meter. Jackson Wood Technology sells kits, but we've not seen one. Also, the July-
August 1985 issue of
Fine Woodworking carried an article on making your own moisture meter.
The meter costs about $30.00 and features a meter type of indicator.
