Paying Homage to the Rotary Tool
If there is one tool that can do nearly
everything, it's the rotary tool. This multi-tasking tool should be one of
your first investments for the wide variety of tasks it can perform.
Here are just a few of the things you can do with a rotary tool and
accessories.(And there are probably a hundred more things I don't have
room to list).
Although these are made may several manufacturers, Dremel seems to be the
name that everyone knows--and for good reason. They make a quality product.
Be prepared to spend a few bucks to get a good one--those $20 imported ones
should be considered disposable.
Almost all of them will have multiple speeds or variable speeds. Depending
on the task, this is going to be very handy. From what I've seen, a lot of
the accessories are interchangeable between manufacturers-- and it's the
accessories that make these so useful
Let's start out with the carbide or high speed steel burr. I use these to
"whittle" the basic shape of the handle, especially in smaller areas where
my belt sander won't reach. You can use these to shape the brass or nickel
silver guards also. Use a light skimming motion--these are aggressive and
will dig in if you use any pressure. Especially the carbide ones. I call it
"whittling".
You can also use the carbide rasps to enlarge pin holes or the slot in a
guard. ( For guard slots though, use a file to finish up to get a good, flat
side). The carbide rasps are strong enough to shape hardened steel, but go
slow.
Small as they are, the sanding drums can be used to finish shaping the
handle. (Actually though, I always recommend hand sanding as your final
step). I typically use a lower speed--these go so fast they can burn the
wood. They wear out fast but fortunately they are economical and easy to
replace.
Cutting disks, in addition to cutting bar or rod stock are also useful for
roughing up the shiny metal surface of the tang, to give the glue something
more to bite into.
I like the slightly larger fiberglass reinforced ones--they hold up a lot
longer and aren't as brittle.
These cutting disks can also be used to profile a blade blank, getting it to
the right shape before going to the grinder. It's a slow process and you'll
eat up a few disks, but it's sure a lot easier than using a hacksaw. In this
photo I'm modifying the tip of a tanto blade I was working on.
Rotary tools also do a great job acting as a small router . This attachment is
attached by replacing the front collar on the tool and provides a
range of depth adjustment.
I use this routing attachment for cutting the grooves on the inside of two
halves of a handle to accept the tang from a hidden tang knife. Although you
can freehand it, it prefer to hot glue a guide fence on a scrap of
wood to run the base against. (Hot glue the scales down, too with a single
dab of glue). I like to use a 1/4" square bottom router bit
And this is what you'll end up with. Pop the scales off and glue them back
together in preparation for epoxying the hidden tang blade in.
This is a slightly larger router base that Dremel makes. I've used this more
for small woodworking projects than for knifemaking, but it's still pretty
handy.
Another useful accessory is the Dremel base that turns your rotary tool into
a drill press. With an inexpensive sliding cross vise, this could
easily be used as a mini-milling machine
Being the cheap guy that I am, I found a drill press stand that was designed
to hold a corded hand held drill at a garage sale for $5.00 . Using
stainless steel hose clamps, it was easy to strap the rotary tool in. It was supposed to
be temporary but I've been using it for 10 years now.
Although it won't replace the buffing wheel on your grinder, those little
buffing wheels are great for polishing small areas or items.
Oh, didn't I mention that you can drill with a rotary tool? These are best
used for smaller drilling jobs (don't throw away your electric hand drill or
drill press!) such as the lacing holes on this sheath I'm making. Whole lot
faster than using an awl.
By the way, most rotary tools are designed to work with accessories with a
1/8" shaft. For smaller drills or accessories, Dremel makes a keyless chuck
that works like the chuck on your hand drill. Since you are no longer
restricted to accessories with a 1/8" shaft, using this gives you the option
to use a much wider ( read smaller) range of accessories and drills.
They always give you an assortment of small grinding stones when you but a
kit. These are great for sharpening lawnmower blades and chainsaws but
I would never EVER consider using them to sharpen a knife. Too hard to get a
consistent edge.
Yeah,yeah, I know that there's like a million other things that the rotary
tool can do and that ( to mix a metaphor) I only scratched the tip of the
iceberg. This little homage to the rotary tool was only meant to illustrate
a few of the more common ones and to hopefully to give you some ideas.
