Joan I have several suggestions for elimination of the burrs you
- Try using a new blade (dull blades will produce burrs). 2.
Generously lubricate your coil with Gesswein’s “Lube Stick” or
Rio’s “Bur-Life” in stick form. 3. Place the blade (surrounded
by its guard/guide) in the coil holder before starting your flex-
shaft. Run your flexshaft at top speed - about 18,000 rpm - and
feed it through the coil rapidly. Take your foot off the pedal
as soon as you’ve completed the cut. If you continue to run it
you’ll only be generating additional heat which you don’t want to
do. Let it come to a complete stop before retracting it from the
coil holder. 4. To clean your jump rings you can pickle them or
put them into an ultrasonic machine. If you don’t have these, you
can also put them into a screw top jar containing hot water and a
little dishwasher detergent (no soap). Close the jar and shake it
for about 10 seconds. Pour the contents into a strainer and run
hot water through it. Your jump rings will sparkle! 5. If the
wire you’re using is dead soft, that could contribute to the burr
problem. Try 1/4 or 1/2 hard if you can work with them.
A sharp blade with no missing teeth is extremely important. For
economy you want to treat it as well as you can. 1,2 & 3 above do
As a last resort you could tumble the rings for about 15
minutes. A few strokes with a diamond nail file will also remove
any slight burr.
The blades that come with Jump Ringer are American made and are
the finest quality for this purpose. Gesswein, Rio Grande and
many other tool dealers carry them as replacement blades.
Hope this is of help to you.
