I wasn't aware that A36 specified anything other than minimum mechanical properties; if you have a reference that specifies the alloy properties, say percentage of carbon, I'd love to see it. On the
There is also the adhesive-filled heat shrink; this stuff is usually provided with hard-line connector kits. I have been using SPC Technology type PHS polyolefin heat shrink at work recently. It has
When you cut the heat shrink off, the adhesive peels off with the heat shrink. It acts more like a conformal coating than an adhesive. As for the "snot", it's definitely a silicone-based substance; I
I have done something like this. First, call the Readymix company and find out how much time you will be allowed to unload the truck. Next, find something like four construction-size wheelbarrows and
Has anyone modeled the Telrex-style through-the-boom element mounting scheme, for use in an analysis program? I have a brand-new, never used 40M335, without any assembly instructions. Apparently, the
First, I don't like to use UHF connectors at all; N connectors are easier to install and more trouble-free over the long haul. But in the few cases where PL-259s are unavoidable, I *do* use a solderi
Lessee, you don't do it very often, the rubber thing is too wide, won't screw together... sounds like a personal problem to me, Barry <G>. Actually, if you mean the rubber washer seems to be so thick
Silver easily forms an oxide which, as you have commented, is relatively easy to remove and is not an insulator (it's also not a great conductor, compared to the base silver). A far worse "corrosion"
Yes, the "sackcrete" stuff will produce good concrete if mixed properly, but not in this gentleman's 4' x 4' x 6' hole. I claim that there's no way in hell to mix 3 2/3 cubic yards of sack mix fast e
Steel welding wire (MIG, TIG, gas) has a VERY thin copper flash to retard rusting in protected environments; it will rust in a heartbeat in outdoor applications. geo, n4ua
Steve, Stainless Nylock (or any other ss shakeproof nut) on stainless bolts is an invitation to galling, metal-to-metal welding. If the parts are perfectly clean, they will gall every time. I *do* us
It's hard to beat cored brick as an antenna counterweight. The three-hole or the six-hole have many of the same advantages as rocks; they weather slowly, they are available wherever buildings are bei
