Cotton covered wire is flammable. remember the cigarette lighters in cars? They glow to light a cigarette and will set combustibles on fire. It is done with 'only' 12 volts. It is not the voltage perse that causes the wire to glow when there is a short or overload , It is the amount of CURRENT in Amps that flows through the wire. All wire sizes have max. current ratings. Exceed that and it will melt the insulation. In cotton it will set it on fire. That is also the reason why fuses are now spec'd in all organ wiring, so rather than melting/flaming your wires the fuse goes.   John V

Extremely quiet, smooth running, 18" pressure, 3 stage, 60 cfm, 120 volt = and cheap as dirt - $18.99. Two or more in parallel would give more volume at = the same pressure. I have had several for various uses. One I used for a = portative of flutes. Another I used as the air supply in a small theatre console so = as not to run a long air line - perfect, even without regulation and sound deadening. And, they are great for testing. Just this morning I ran one = of these little blowers with discharge wide open (which is fully loaded for a = turbine) and measured the line current which turned out to be exactly the name plate current. Which also means, in my book, not overloaded. This topic of = running wide open has been discussed before. The blower mfg would be the authority but = I have never seen a warning on any turbine blower that says not to operate = without resistance to the discharge. Motor nameplate currrent would be the = defining factor.   John

The blower mfg would be the authority = but I have > never seen a warning on any turbine blower that says not to operate without > resistance to the discharge. Motor nameplate currrent would be the defining > factor.     From the Instruction Manual supplied by the Spencer Turbine Company, page = 6 ("Special Notes"):   "If there is occasion to start the ORGOBLO before wind connection with the organ has been completed, be sure to cover or block off the intake of the machine; otherwise you will overload the motor and possibly injure it." Clearly it is intended that the motor operate with a load present, and blocking the output accomplishes the same thing (in essence, placing a "virtual organ" at the output, since the winding system in a pipe organ is normally closed).   Smaller blowers, such as Meidingers and Laukhuffs, require the same treatment. Our company has had occasion to replace such blowers when = their wind sleeves have blown off or rotted, and the motors have run without load; they burn up, folks.   Very small blowers may have different parameters; at $19 a shot it = probably doesn't matter very much, unless it burns your house down too. :)   By the way, in the Special Notes section of the Spencer manual, it also warns:   "Do not under any condition try to hang the ORGOBLO from the ceiling or rafters overhead".   Funny, it never occurred to me to try. . .   Greg Rister Pipe Organ Craftsmen Pomona, California

Sometimes "buzzwords" that make communication easier in an industry do not carry the same information in another industry, and can be confusing especially on a world-wide list like this.   Later,   Mickey   > Subject: Cutting/replacing cables > From: "F.
