Stuff the wall full of something deadening, like maybe 'Cocoon' brand shreded paper insulation, and its amazing how little noise above 30 hz gets in or out of such a room. -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.

(but barrels wear from burning the steel at the throat and moly won't stop that) I can see about a 50 fps improvement in speed on my chronograph, and a slightly lower std deviation to the speed. One can also give the barrel a coat, and with a clean barrel, it might do some good there too, but it didn't do anything for the accuracy which it was supposed to help. But, when I finally got the barrel cleaned out well enough to see what I had, what I had was a bunch of deep rust pits in the last 1.5" to the muzzle. That's either new barrel time, or cut it off and recrown. My little lathe wouldn't let me cut more than about 1.25", but cutting it off that much took a 5" group down to 1.5". I assume, since WV always schedules deer season in the middle of a *#@&^$# monsoon, that I must have left a few drops of rain in the barrel sometime in the past. I really should do 2 things, one, take it down to Douglas in Charleston for a fresh barrel (its probably got 3500 rounds since it was fresh in '72) and learn to shoot through a friggin balloon stretched over the muzzle to keep the rain out. :) >> For the deburring etc, I haven't tried it as my own HF cement mixer >> still gets some use as a cement mixer around here, but I sure like the >> idea.

For deburring and cleaning in a rotating drum you would want some backward facing fins about 2-3 inches long so as to only lift the material up about 1/2 the way up the side of the barrel or less. This keeps a nice steady rolling motion instead of a falling from the top which will damage parts. I've built about 20 of these for inline cleaning of parts at about 1/2 ton per hour rate of parts.

Re: [Emc-users] vibratory polishing/deburring
Hi all, Just to confuse the issue: has anyone done electrolytic polishingd/ deburring. It should work fine with diluted sulfuric acid for steel of stainless steel but on aluminum you probably get both deburring and anodizing. Not that that is bad if you don't want a bright surface. Just thinking out-loud. I did find one reference to electropolishing in various alkali hydroxides. Aluminum is amphoteric so you can etch it with either a base or an acid. You will need ventilation because of the hydrogen given off.

Clever! My gut feeling has been that clothes-dryer tumbling action would take too long, and/or remove material too aggressively, even though these ideas seem to contradict each other. Honestly, though, a lot of things I'm going to be making are so tiny - e.g. less than 1" cubed - that I'm tempted to simply return to my youth with one of these: http://www.amazon.com/NSI-26354-Rock-Tumbler/dp/B0ISUU -Gary > Gentlemen, > We bought a cement mixer from Harbor Freight. > The local pickup bed spray armor guys sprayed the inside and > outside of the barrel. > Works great. > Media can be very aggressive and the coating shows very little > wear after many hours use. > thanks > Stuart - This SF.net email is sponsored by: Microsoft Defy all challenges.

Re: [Emc-users] vibratory polishing/deburring
Gary: I have the Lyman Turbo Pro, which is essentially the same thing (I think Midway carries it also). It does a great job cleaning ammunition brass. The vibratory action is quite good - sorta reminds me of a slow mini tornado with a rolling action, where the media and the shells come up from the center and then down on the outside, while also traveling around the drum. As far as deburring, this would have more to do with the type media you are using than anything else. For polishing, the normal media is either coarse-ground walnut shells or corn cob granules. I assume, for deburring, you plan on using something like BBs?? The only problem here would be total weight. The heavier media may not vibrate well enough to be effective. If you wish to email me off-line, I can provide you more detail on how these vibratory polishers work, etc. Good luck! Dennis - This SF.net email is sponsored by: Microsoft Defy all challenges.

Re: [Emc-users] vibratory polishing/deburring
That's the one I have and it does fine, but as Phil said you need to match the cutting medium to the work. Phil's suggestion to line the bowl is a good one, too. I'm not using an agressive cutting material, but I can see where the bowl would wear out quickly with something that was agressive.

Re: [Emc-users] vibratory polishing/deburring
Thanks for all the great info, Phil! I have decided to go with the HF machine: http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=93252 The things I'm making fit in my hand, so I don't need a huge floor model, thankfully. I was just wondering if these cheap machines would do anything at all, and it sounds like they will. It seems more like the medium and tumble-time will make the real difference here. I think I'll give your plasti-dip suggestion a tryout, too, as I'm worried about eating away the bowl with certain more abrasive media. I think I'll see what the internet has to say about homemade/found media, too, as some of the abrasives on the page you linked are pretty pricey for my hobby-only needs.

Re: [Emc-users] vibratory polishing/deburring
I'm very glad to hear that these are in actual CNC machine shop use. That adds some credibility. I was afraid to pick one up, and then sit there all day, only to find nothing changing on the parts. I'm going to snag this one: http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=93252 It's $10 less than my 1/8" dovetail bit, and much larger, and more useful!
