Magging an Avet JX
Moving to California
from the Great Lakes region I found myself researching extensively for my
first ocean reel. I wanted quality and value. I also wanted a general all
around reel that I could make do for a variety of conditions and targets. I
eventually purchased a Avet JX from the Charkster that I chose as a reel to
cover 95% of any situation I might encounter on any 2 day trip out of
southern California.. I can stuff 400 + yds of 30lb. Spectra with
appropriate fluorocarbon leader on this reel. Its bolted to a 7 ft.
15-40 LB class graphite rod, I could not be happier.
Well, yes I could be
happier. This wonder reel has excellent free spool. While this feature is
desirable for fly lining and indicates an exceptionally well engineered
reel, this amazing feature requires a highly educated thumb when casting
for maximum distance. Casting with 75% effort presents little problem for
skilled anglers . Its when you really crank in the power to get that maximum
distance that problems arise. Lets redefine “problems” as “backlash
extrodinare”. Yes, it can be minimized but the thumb control required
negates a lot of the distance potential for the extra power exerted.
I needed a solution to
this annoyance. After an extensive net search of long distance casting I
came across some East Coast sites where shore fishermen were MAGGING their
reels for max distance when surf casting . I also learned that Magging a
reel is not rocket science and is easy to do. Magging is nothing new. It has
been around for some time and is used today by various manufactures in
Why magging works is a
result of the application of Lenz’s Law. Basically, when a rotating metallic
object (your reel spool) is within a magnetic field an opposing field is
induced into the rotating metal which counteracts the field of the
stationary magnet. Consequently resistance is induced into the spool
slowing it down. The strength of this resistance is proportional to the
rotational speed of the spool and the strength of the magnet. Thus the
maximum amount of resistance is generated at maximum spool speed and is
viturelally non-existant at slow rotational speeds. Backlashes are
generated when the spool speed exceeds the speed required to feed line out
to the object that has been cast. Magging stops the backlash because it
applies spool resistance when it is needed most, at maximum spool speed.
The following are
detailed instructions on magging a reel. I will outline what I did to Mag
the Avet JX but the basic principal can be applied to any reel that has a
metallic spool.. Graphite or composite spools cannot be magged.
You will first need a
source for magnets. Not your ordinary magnets but the strongest available
magnets that you can buy. Neodymium Iron Boron Rare Earth Magnets are the
only type to use. Do not substitute. These Rare Earth Magnets are 50
times stronger than standard magnets and their effect can be increased by a
factor of 2 to 4 with proper installation. They can be purchased on line
at: www.leevalley.com, or phone # 800 871 8158. On the web site go to
Hardware then go to Magnets. To properly educate yourself read
the “About Rare Earth Magnets” page. It is a must read.
Now, order the
following: Minimum of 3 each.
#99K31.01 Magnet ¼” OD
- 1/10” Thick
#99K32.03 Magnet 3/8”
OD - 1/10” Thick
#99K32.51 Cup for ¼”
#99K32.52 Cup for 3/8”
#99K32.61 Washer for ¼”
#99K32.62 Washer for
As you can see on the
web site the material is top notch and inexpensive.
This order will give
you ample supplies to mag a couple of reels and allows for a blunder or
two. You will need some standard air dry hobby glue, even Elmers will work.
You will also need a small amount of 2 part epoxy for final attachment of
the magnets to the inside of the reel. I like JB Weld, its bullet proof but
any Epoxy will do. And some type of degreaser to clean a spot inside the
reel so the epoxy will stick to the reel. I use isopropyl alcohol. You
might also need access to a small bench grinder to shape the magnet and or
magnet base if necessary. You can use a file if you cannot get access to a
grinder. And finally some light grease to coat the magnet and its base for
salt water corrosion protection. I use Silicone grease but almost any type
will suffice. You can always take a Q-Tip and spread some existing grease in
your reel over the magnet assembly.
There are three ways to
mount the magnets. By itself, on a steel washer and inside the correct size
steel cup. By itself is one strength value, on a steel washer produces 2X
the rated strength of the magnet and inside a steel cup produces 4X the
rated strength of the magnet used. Explanation of these values are on the
Lee Valley Site.
Below shows the
Magnets, Flat Washers and Cup Holder for the
¼” & 3/8” sizes.
Remove the 2 screws on
the handle side of the JX and remove the entire side plate and spool
assembly. Real simple. Now the magnet assemble chosen will be attached to
the inside of the end housing opposite the handle. Mount the magnet assemble
as far out from the center as possible. My JX has a clicker assemble so I
mounted the magnet assembly next to the OD of the clicker brass ring. What
magnet you use and what steel backing you use depends on trial and error.
You will have to experiment with this. Take a look at the pics supplied to
get the idea. You install just a magnet, a washer and a magnet or a cup and
magnet, just guess to start.
dismantled reel in the vertical position place the chosen magnet,
washer/magnet or cup/magnet combination on the inside back plate as far to
the outside as possible then carefully re-assemble the reel, do not screw
down yet, now rotate the spool to check for interference between the
installed magnet assemble and the rotating spool. Interference will show up
as the inability to re-assemble the reel because the magnet assemble is too
high or when you rotate the spool it will move the magnet assembly from the
original position that you placed it. Do what ever is necessary to create
clearance between the magnet and spool. They must not touch. Some
suggestions would be to grind down the thickness or the edge of the steel
washer or the top edge of the magnet may need clearance. All adjustments
must be made to the steel washer or magnet, do not grind on your reel
housing or spool. If modification of the magnet is required, and you are
using a grinder, be sure to keep the magnet cool by submerging in water
every few seconds of grinding as temperatures above 400 deg.F will destroy
the strength of the magnet. Now insert the 2 screws and tighten down and
re-check for clearance and adjust as necessary.
end plate and magnet assembly with the alcohol and attach the steel washer
or cup with the air dry glue. Let set overnight. The air dry glue is used so
it can be removed easily for the next trial magnet set up. Now just set the
magnet you have chosen on top of the steel washer or in the cup. Don’t worry
it will stay put. Now re-assemble the reel, do not bolt down, just hand
assemble and carefully check for spool clearance again between the magnet
and the spool.. If it does not clear adjust some thing accordingly. All
should be as it was before.
Now take a
dummy plug or iron, (1-3 oz) remove the hooks, go to the local park and
start casting. Lightly at first, keep increasing power until either you have
no more power or backlashes start being generated. If you are casting with
full power and you are getting no backlash at all you have too much control.
You need to reduce the magnetic force until you just start to get a little
loose line, not a backlash, once in a few cast. This will be just about
right. You can however adjust to your own personal preference.
magnetic force by increasing the distance between the magnet and the spool,
going from a cup to a flat washer or no washer, using a smaller magnet or
fewer magnets or any combination of the above. If you need to increase the
magnetic force decrease the distance between the magnet and the spool, go
from a flat washer to a cup installation, install a bigger magnet or more
magnets or any combination of the above . ( if you install multiple
magnets be sure the polarities are in the same direction)
When you have
developed a combination you like remove the set up from the reel, scrape
off all the air dry glue, clean with alcohol and re-attach with Two part
Epoxy. Always re-check for clearance. Finally, coat the entire modification
with grease for corrosion protection. Below Pic shows the completed Magging.
For the Avet JX I
ended up using a 3/8”magnet inside a 3/8 steel cup with about .010” ground
off the bottom of the magnet cup and the outside top edge of the cup ground
down to clear the outer edge of the spool and the inside of the cup ground
to move the entire assembly closer to the center so there would be room for
the spool lip.

image right shows the inside of the
magnet cup ground which was required to move the entire assembly closer to
the center to make room for the inside of the spool lip.
image right shows the outside of the magnet cup assembly ground to complete
the clearance required for the inside lip on the spool. Also notice that I
had to grind a little off the top outside edge of the magnet in order to
complete the spool clearance.

SX, MX and LX/JX (have
the same construction.)
Magging my reel has
eliminated all backlashing. I can consistently get 60 - 70 yards with my 7
ft. rod. With a good 9-10 ft. rod and a small high quality reel you might
realistically expect to get 100 yds slinging iron.
Some thoughts on
backlashes: I use 30lb Spectra line with about 4-6ft. of Fluorocarbon
leader (15 to 40 lb.) this combo works great, I do not want any back
lashes. Back lashes and Spectra are mortal enemies. The no stretch quality
of spectra causes extreme weak spots in the line where the back lash snags
up the line and makes a birds nest. This snagging in the Spectra line
reduces the test by about half, I have even had the Spectra break when
backlashed. You do not want to get a backlash in your Spectra. If you do get
a good backlash you might want to cut that section of line out. A lot of
guys use up to a 100yd top shot of mono which eliminates this issue.
Magging your reel can
provide great benefits. Your reel will free line as before and give you the
confidence to power cast when necessary.
