UniqueTek Micrometer Powder Bar Kit Manual

Micrometer Powder Bar Kit
For the Dillon Auto Powder Measure *
Thank you for buying the UniqueTek Micrometer
™
Powder Bar Kit for your Dillon Precision Auto Powder
Measure. This kit includes everything you need to
convert your Powder Bar to a Micrometer Powder Bar.
This conversion kit is compatible with all Dillon Powder
Bars (Extra Small, Small, Large, Magnum, Belted
Magnum* plus the SL 900 Shot Bar*).
* The Belted Magnum powder bar and SL900 Shot Bar require minor
modification. See Note in Step 4 of instructions.
If you have any questions about installation, operation or experience any problem with your micrometer, please call
me first. I can often resolve the problem over the phone (480-216-2041 cell). – Lee
Step 1: Place an Index Mark on Powder Bar
The Auto Powder Measure is oriented differently on each Dillon press. Before
removing the powder bar, decide from which side you will want to view the
micrometer when adjusting the powder charge. As you are facing the press, you will
typically adjust the micrometer from the side shown below.
• Square Deal B – Left Side
• RL 550B – Right Side
Mark a line on that side of the powder bar, near the adjustment screw, with a pencil,
white crayon or other marker that is easily visible but removable. This line will be
used later to orient the micrometer index mark for easy reading. On the XL 650 and
Square Deal B you will notice that the micrometer numbers will be upside-down. But
this orientation will be much easier to see during adjustment than if it was oriented
on the opposite side of the powder bar as with the other presses.
Step 2: Remove Powder Bar
Remove the Powder Bar from the Powder Measure. (Refer to Auto Powder Measure instruction manual for details.)
Step 3: Disassemble the Powder Bar
NOTE: Before disassembly, look closely at the Powder Bar and note that Powder Bar Inserts (Ex-Small, Small and
Large) and some Powder Bars (Small and Large) have a flat side and a side with a cavity. The cavities must always
be on the bottom side of the Powder Bar.
a. Remove the Powder Bar Post. Press the bolt head against a
hard surface to compress the spring washer while pulling out
the Powder Bar Post. The Belted Magnum powder bar and
SL900 Shot Bar have a 3/8" set screw instead of a powder bar
post. Remove the set screw using a 3/16" hex key.
b. Remove the Powder Bar Adjustment Screw.
c. Set aside the Powder Bar Adjustment Screw, spring washer
and flat washer. They will no longer be used.
Step 4: Prepare the Powder Bar for Installation **
The Teflon coating must be completely removed from the hole in the end of the powder bar where the adjustment
screw was removed. Use a round file or rolled up sandpaper to scrape away the Teflon coating, leaving a fresh bare
metal surface for the LocTite to achieve a good bond. Clean the hole with rubbing alcohol to remove any residue.
Note: If you happen to have a 7mm thread tap, it does a quick job of cutting through the Teflon coating and exposing clean bare metal for the
Loctite to achieve a solid bond. Only a 7mm tap is the correct size. Do not substitute any other size metric or SAE tap.
** The Belted Magnum powder bar and SL900 Shot Bar adjustment screw hole is smaller than on the other powder bars and must be
enlarged using a 17/64" drill bit before installing the micrometer. Some older Small and Large powder bars may also require enlarging.
