» Getting Your Dredging Equipment Ready for the Season.

It is getting pretty close to dredging time, and if you are anything like me and the many other dredgers I know, you are probably just itching to get started.

My partners and I, from past experience, now spend the necessary time and energy, before the dredging season starts, in getting all of our equipment repaired-to avoid the otherwise often confrontations with Murphy’s Law.

Some of the standard things we go through are as follows:

Engine and Pump: We always replace the spark plug, motor oil, points and condenser and air filter at the beginning of every season. We also pull the pump impeller to make sure it is not worn or damaged, and to make sure nothing is lodged in it. And we check the pump seal and replace it if it looks the least bit worn.

Air Compressor System: All of the compressors I have seen on gold dredges have reed valves. These are stainless steel plates which allow air to only flow one way through a chamber. These reed valves ought to be cleaned, polished and straightened at the beginning of every season. Some compressors have rubber diaphragms and some have piston rings. These ought to be checked and replaced if necessary. Rebuild kits are generally available for each type of compressor-usually from your local prospecting equipment dealer.

We always open up our regulators and blow them out with compressed air. You will want to check to make sure there are no holes in the rubber diaphragm, and make sure the rubber exhaust seal is working properly. If you have problems with water getting inside your regulator, it is almost always because of a worn out rubber exhaust valve. These are easy to obtain and replace.

It is especially important to open up and clean any check (one-way flow) valves in the air system. We also always soak our air lines in a very mild bleach-water solution before starting a season. We let the airline sink in a tub of the solution to allow the bleach to kill off any fungus which has grown inside the airline. This is to avoid potential respiratory problems from the fungus. The line needs to be thoroughly rinsed with fresh water afterwards.

We check all of our airlines and fittings to make sure everything is working properly-no leaks, and no weak connections!

We thoroughly clean out our air reserve tank to make sure there is no rust, fungus or other substances which could potentially cause problems.

Dredge (Structural): And, of course, we go over the sluice boxes, dredge frame and jets to make sure there are no holes, cracks or other structural problems. And if we find problems, we fix them on the spot. No need to wait until it becomes a more serious problem during the season.

We hit all of the steel with a wire brush and follow up with a fresh paint-job every spring. It’s nice to start the season off looking good!

We go through all of our rope and make sure all of the weak points are cut out and spliced back together, and all of the ends are spliced or melted so there are no frayed ends.

Diving Gear: We go through all of our diving gear, replacing anything that is worn out, patching holes in suits, etc. No need to be any colder than necessary during the early spring!

While fixing up the dredging equipment is not as good as using it, I personally gain a great deal of satisfaction getting it all prepared for the season. And, it’s always a good feeling when I do get out on the river when I have it all together the way it should be. And when “Mr. Murphy” comes knocking at my door, at least I know it wasn’t because I failed to plan ahead.
