"Bill Nelson" writes: << .... but I was taught that you weld when the filler rod (if used) is of the same metal as the items to be fastened - and braze when the filler rod is of a different material. >> Bill, The difference between welding and brazing (which includes soldering and silver soldering) is that in welding, the parent material (the things you are joining), actually become molten at the weld site. In brazing, the parent metal is only heated enough to melt the joining material, allowing the joining material to flow to any area sufficiently heated, including voids, lapped joints and between the inner and outer surfaces of mating tubes. The joining material then forms a chemical bond with the parent metal. Brazing is basicly very high temperature soldering or soldering is very low temperature brazing. Silver solder falls in the middle. In welding, filler rod may or may not be the same alloy as the parent metal although it will be the same family, i.e. iron/steel for iron and steel; copper,brass, bronze, zinc, tin for that group and aluminum for aluminum. The filler rod used depends on what the parent metals are and the desired characteristics of the finished weld. There are many more esoteric combinations of parent metal/filler for specific purposes far beyond my knowledge. Brazing can be stronger than welding in certain circumstances. Remember back when bicycle frames were still all steel tube? Brazed frames were stronger and lighter than welded frames. The reason was that in welded frames the tubes were joined directly to one another.=20 The welding process concentrated the heat just at the joint and required heavier tubing to make a strong joint without burning through. The brazed frames were joined with "fittings" similar to plumbing "els" and "tees" etc. In the brazed joint, the entire mating surface of the tube and fitting were the fastened joint, making a joint with as much as 50 times the joined surface area. Also the brazing process allowed the use of stiffer, lighter and thinner walled tubing. Today of course, metal for anything but a low end bike is unheard of. Hope that clears up the difference for you. --=20 Michael Michael Powers 413-863-4376 home 413-522-3036 cell ------------------------------ Date: Sat, 4 Jun 2005 15:44:10 -0400 (EDT) From: murr rhame Subject: Shiny People on Mythbusters Message-ID: The Mythbusters show on the Discovery Channel is doing a season rerun today. They revisited a couple of metallic makeup myths, this time painting one of the assistants silver. Last season, they painted Jamie gold, using powdered brass (bronzing powder) mixed with latex... Latex was a very poor choice for a binder. Latex sets airtight and many people are allergic to latex. Jamie had to cut the experiment short when he had an odd reaction. I suspect some sort of allergic reaction to the latex was to blame. The tin man legend, mentioned on Mythbusters, isn't a myth. Buddy Ebsen was originally cast as the tin man in the Wizard of OZ movie. They used loose powdered aluminum for his silver tin man makeup. Buddy inhaled so much aluminum powder. It coated his lungs and made him very ill. He ended up in the hospital for weeks. For the movie, they switched to an aluminum paste for the replacement tin man. With a paste makeup, there's no dust in the air. The Mythbusters didn't mention the formula for their silver paste on the show. I'm pretty sure the binder they used was plain glycerin. Glycerin is non-toxic and water soluble. It's very easy to wash off. You can sweat through a coating of glycerin... The only down side is that it rubs off very easily. Anything the performer touches will be smudged. About 30 years ago, I help create a gold makeup effect for a living statue of Buddha in a production of the King and I. We used glycerin mixed with gold colored metallic bronzing powder to produce the makeup. This was done long before products had Material Data Safety Sheets... I didn't know what exactly was in the bronzing powder or if it would be harmful to apply it to the performer's hair and a large area of his skin. I called the National Poison Control Center in Atlanta and asked them to sort it out. The poison control center folks called the bronzing powder manufacturer and got the contents of the powder... I'm sure this was a more interesting problem for them than the typical panic call from a parent who's kid just drank a bottle of shoe polish... After doing a little research, they called back and said the glycerin and bronzing powder paste shouldn't be a problem. They suggested a coat of plain glycerin before applying the golden goo. Other than having a touch of green tarnish in the arm pits, the actor who played to Buddha survived unscathed. I used the same bronzing powder mixed with latex to paint some of the set and props. Mixing your own metallic pigments with a water based binder is the only way I know of to get an inexpensive water based metallic paint. - murr - ------------------------------ From: FrankWood95 [at] aol.com Message-ID: Date: Sat, 4 Jun 2005 17:17:17 EDT Subject: Re: Star*Par Vs.

TIG leaves the best looking weld, and is easy to use on aluminum, easy being a relative term. >> I agree with the query on "Pseudo-structural". Either a weld is strong enough to do its job, or it isn't. But what do we mean by a weld? To me, in implies heating the weld area to melting point of the base material, and adding a suitable filler which will alloy with this to make a strong joint. That is the real basics. We are looking at temperatures of 1,800C here, for steel, and this brings in another problem. Oxidation of the surfaces. This is one reason why there are so many different methods, as they all use different techniques to prevent this. Prrimitive arc welding uses a coating on the rod of weld metal, which decomposes to blanket the weld area in an oxygen-free zone. The oxy-acetylene flame can be adjusted to provide a similar effect with a slight excess of acetylene in the flame. The various IG methods blanket the weld area with inert gases. They all need some degree of expertise and training. Remember that for many years, ocean-going ships were welded together. We're talking about butt-welding inch or more thick steel plates togther here, which is more than a theatrical environment usually needs. Aluminium is different. While the temperatures are lower, about 600C, the metal has a strong oxide layer, which accounts for its corrosion resistance. This needs to be destroyed to make a sound weld. Brazing is different again. It is similar in principle to soft soldering, which most of us do. Only the temperatures and alloys are different. The essential here is that the solder material will "wet" both the surfaces to be joined, and, of course the prevention of oxidation. When I learned to braze, borax was the standard flux: modern soft solders use various resins. ------------------------------ From: FrankWood95 [at] aol.com Message-ID: <1a3.3505a55c.2fd3745f [at] aol.com> Date: Sat, 4 Jun 2005 17:17:19 EDT Subject: Re: Star*Par Vs.

Few people lighting a straight play, as you do, would consider a huge rig of par cans, if any. And if they did, it would likely be as a special, or maybe as part of a wash. BUT you keep forgetting that there is a whole world of theatre out there that you aren't and won't be a part of, and for SOME of their shows/events, the par can is an absolute top-line solution. It's not just rock shows, but dance shows, pantomimes, and much more. In my venue, for example, straight plays are very much in the minority on the very full programme. BUT there are 8 in the standard rig (4 each side on drop bars) which can and are used as side lights where necessary and to VERY good effect on a variety of occasions. Use a tool where you need a tool. Simple. If the tool you have in your hand won't do the job in front of you, go to the box and get a different tool.

Of course, I was after a slightly deeper sound of a boat's steam whistle, but the principle is the same. I was what you might call, whistle challenged. For the life of me I could never make a whistle. I followed the Boy Scout handbook religiously, but never was able to figure them out. For my boat whistle, I had in mind of borrowing a Calliope pipe and running it off of compressed air. As luck would have it, (bad luck) none of the local Calliope owners had any extra pipes. Finally one organ officiando explained in a way I could understand, how whistles work. The light bulb went on and I spent a month making whistles of every size and shape. Enough of my problems, here's what I did for the show. First I made a whistle (actually a pair tuned roughly a major 3rd a part). I made them out of PVC which isn't recommend for compressed air, but it's easy enough to make them out of steel pipe. I hooked the pair to supply line and hung them in the fly just above the set for the deck of the ship. I use a CO2 bottle with a regulator and fed the whistles with about 25PSI. Not only did it sound great but the "steam" blew down from the fly just like it might on a ship. [Humor note: During one dress rehearsal, I let go with far too much pressure and the CO2 created a wind storm on the set. All the dancers' skirts were blown up around their necks. Great scream. I lost big bucks because I refused to do it for closing night.] If you want construction details on the pipe itself, I'll have to draw some pictures. Basically, you cut a notch, like you see in an organ pipe. Then you put a plug in the tube below the notch that is flat on one side. You're trying to create a flat stream of air aimed at the upper lip of the notch. The secret is that the air stream blowing over the notch creates a low pressure area inside the pipe which bends the airstream into the pipe. That of course destroys the vacuum and the air stream returns to its original path. Oscillation occurs, noise is made and everyone is happy. Roughly speaking, middle C on the piano requires a pipe 2 foot long with a cap on the end. Half that for every octave you want to go higher.

First the easy question. I need to get direction from NJ to Mutual Hardware. In other words, we take light rail to PATH, from this point we need a little direction. also How long this would take would be very helpfull. Second. Is their a place like barbazon, only for Sound guys. Example, large showroom, tool, specialty tools, or just your favorite place to get sound gear.

Take PATH to the 33rd Street Station in NYC. At 33rd Street Station, Transfer to the "F" line subway towards uptown/Queens. Get off at 21st Street. That is the first station after you leave Manhattan and enter Queens. I would guess about 15 minutes on the subway. You can walk to Mutual by heading north on 21st Street and make a left on 37th Avenue. It takes approximately 10 to 15 minutes to walk (from Mutuals website). > Second.

Not a sound guy myself, but Manny's Music, 48th Street, between 6th and 7th in Manhattan, seems to have a large selection of gear on display. Good Luck shopping.

How high a pressure you put in the tank and how good a welder you are. An air tank you are maxing out at 150 psi versus the air tank you are putting in 3000 psi? For the former, you could probably just fix it with a little JBweld even easier than actually welding it. For the latter case, toss it. --Dale ------------------------------ Message-ID: From: "Occy" Cc: alf.sauve [at] mindspring.com (Alf Sauve) References: Subject: Re: RE Todd Whistle Date: Sat, 4 Jun 2005 19:37:33 -0700 Alf, So your telling me that I can take any object may it be round, square or any other sided. Cut a notch some place in the object notch being roughly flat on the bottom and say 60 degrees up to the out side of the object and the flat cut is about 1/4 if the in diameter of the conduit that's going to flow the air and cap the top of the object and cap the object and stuff a another plug in the bottom with a hole to inject air and I get a power whistle? Isn't the suppose to be some kind of angle facing the hole on the conduit on the bottom plug where the air is inserted? I have never recall a pipe organ with a seeable cap maybe it was just hidden for looks, and thinking of it I do remember steam locomotives of the 60's having a nice very shinny brass top on the whistles. ----- Original Message ----- From: "Alf Sauve" > Bruce, > > I researched this for a production of Anything Goes.
