Dunno if this needs to be a new thread or just tack on to this thread.
When purchasing my experimental Lyman TS-700 itty bitty thing, a jeweler at Cabela's suggested to always fill the basin up to the max line, even if not doing a full load of brass or similar. He mentioned it was hard on the transducers if ya don't do so and can cause early burn out... especially if you run the machine empty.
Heating the solution seems helps it work better. The TS-700 doesn't have a heating element, most of the more expensive ($110+) have a heating element. I just threw my distilled water in the microwave.
While Lyman and others suggest using tap water, the jeweler mentioned either boiling your tap water or using distilled water to get rid of chlorine.
For those of us not willing to spend $20 a bottle on cleaning solution.... this is what I've worked out so far.
Same jeweler suggested a cap full of Mr Clean and and a cap full of ammonia per cup of water.
Known caveats:
* mr clean is a very low solution of sodium hydroxide based
** ie: lye, should be fine afaik.
** straight lye eats aluminum though heh.
* ammonia and brass are historically known to not get along and cause cracking... i've not seen any problems
* seems to work fine, but i've noted discoloration in different brass and such
** working on what's going on.. not sure...
** maybe freshly tumbled brass still has some of the corn/walnet-media activator on it ?
Do NOT use Simple Green. Simple Green is known to wreck havoc with aluminum. Whether if this is gun parts or just the basin of the cleaning device itself.
Some folks have fiddled with citric acid (Zep makes a cleaner based off of it .... copper sulfate... citric acid... i think i like this company! heh).
Actually... these guys appear to have done some extensive testing and I'll go about trying to replicate some of their tests:
http://www.6mmbr.com/ultrasonic.htmlI'll prolly go with attempting variations (time based) of this:
CHEAP and CLEAN
24 minutes - 50% Vinegar + 1 Drop Dish Soap per 8 ounces water
480 seconds - Baking Soda (BS) in water (1 grain BS per ounce of water)
480 seconds - Hot Water
480 seconds - Distilled Water
Total: 48 minutes
The TS-700 doesn't like running for more than 20min at a go... or was it 30 ? I dunno... but the manual says 'let it rest' if ya do extended periods heh. I'm also going to have to do something with the basket, it's darn near impossible to remove from the unit sometimes. Prolly just a couple strings.
Lastly... the TS-700 doesn't have a simple way to dump the solution out. Just gotta flip the whole unit upside down etc. I'll need to go about getting some large jars or something to hold solutions in or something.
Next few days will be fun!
