I bought one several years ago on Bobs recommendation and couldnt be happier theyre a pure joy to solder with. Ive never seen a complete unit at this price; $120 delivered is a steal. http://preview.tinyurl.com/ycgyvj7h Additional accessories like tip cartridges are plentiful on eBay as well both genuine METCAL parts and compatible ones from a company called Thermaltronics. Heres an eBay search for the tip cartridges: http://preview.tinyurl.com/ycjaraz7 Eric do not archive Read this topic online here: http://forums.matronics.com/viewtopic.php?p=474240#474240 ________________________________ Message 2 _____________________________________ Time: 10:51:19 AM PST US From: "Robert L.

Recall that we strive for 'gas tight' connections between the current carrying components of a power pathway. Gas-tightness minimizes electrical resistance in the metallic interfaces, excludes moisture and oxygen that will degrade the joint over time. Whether or not surfaces outside the joint are exposed to the effects of corrosion will have only cosmetic effects on the assembly.

Is it really a good idea to spray connections with something like CorrosionX? If so, would it matter if the parts are sprayed before or after assembly? On Fri, Nov 3, 2017 at 9:50 AM, Robert L.

If so, would it matter if the parts are sprayed >before or after assembly? Any material designed for and effective for corrosion control wouldn't hurt. Spraying before assembly probably wouldn't make much difference. Recall that 'gas tightness' goes hand-in-hand with physical deformation of the metals that make up the joint. Deformation forces for copper alloys will be measured in tens of thousands of pounds per square inch. The compression strength of just about anything you spray on is immeasurably small. It simply extrudes out of the contact area as the make-up forces are applied.

Nuckolls, III" Subject: Re: AeroElectric-List: Re: Constructing an automatic RCA video camera feed splitter My sample camera came last week. Took the thing out of the box and pondered how (1) one might get a grip on the thing to mount it in an airplane and (2) how to wire it up. Had a brain-f@#t and got my camera 'upgraded' as you'll see here http://tinyurl.com/yb4yf2sa This mod installs the camera in a robust housing and brings leads out to airplane friendly harness connector (d-sub). From there, you can simply use a shielded pair of 22AWG to take +5 to the camera on one wire, bring video back on the other. The shielded pair would terminate nicely into your multiplexing box also fitted with a connector of choice. Now that I can grip it and wire it . . . I'll see if I can fire it up this weekend and deduce the DC and signal characteristics of the video output.
