SOUND SUPPRESSOR MODEL HDM
8. Unscrew the front end cap from the tube. Using a 3/8 inch wood dowel,
push the baffle stack out from the rear. Gentle tapping with a small
hammer is acceptable. There are seven baffles and a wave spring.
9. There are no perfect carbon solvents. Softening of the carbon deposits
can be performed with LRM Carbon Cutter. A reasonable alternative is
OxyClean detergent in water. A heated ultrasonic tank may be used.
10. Do not use the vinegar-peroxide internet favorite as it will damage the
aluminum baffles and may damage the black oxide finish of the tube and
end cap.
11. Following cleaning, rinse thoroughly in warm water followed by drying
and oiling the steel parts inside and out.
REASSEMBLY
Reassembly is the reverse of
disassembly. The first step is reas-
sembly of the baffle stack. There are
three different baffles (all K-type),
and their stacking order is important.
The five middle baffles have index-
ing tabs. The rear (blast) baffle dif-
fers from the others in that it has a
hole in the flat portion of the "K." The
front baffle differs in that it does not
have the locating tabs.
The simplest method of reassembly is to stack the baffles in the proper
sequence and orientation on a 1/4 inch diameter rod or dowel approxi-
mately 9 inches long. Please refer to the drawing next page.
1. Place the front baffle, cone down, on the rod. This is the baffle with no
locating tabs on the end of the cone. Orient this baffle conveniently for
reference.
2. Stack the next five baffles on top of the front baffle, rotating each 180° to
the one below. The tabs engage notches in the flat portion of the baffle
below.
3. Stack the blast baffle, again oriented 180° to the one below.
4. Last, place the wave spring on the blast baffle. Be sure the tabs engage
in the notches and the baffles are stacked smoothly.
