Give Freightquote a call. They will get multiple haulers to quote and you can choose. freightquote.com OTOH, UST only uses truckers they know as it is pretty easy to ding/bend a crank up. Nothing but
Your local upscale rental yard will have several alternative forklifts available for unloading, which is your responsibility. "warehouse" forkifts will only work on a good paved surface. "pneumatic t
My experience with a new steel structure was quite different. All heavy structural ("red iron") steel to steel bolts were tightened with a torque wrench. In some cases to 200 ft-lbs for the A36 faste
TVS - transient voltage suppressors, are another choice (TransZorb tm by Vishay) and have some advantages over MOVs on small signal lines. The bidirectional versions are basically two zeners back to
Same as N6RK, I laid my HDX589 over and extended it just enough to get in the 2800. BUT, it is a very very tight fit with minimal clearance, so check very carefully for interference on the next lower
I had 7 2.5kw arrays (17.5kw) each one on an 8" sch 40 pipe buried 12' in 6 yards of concrete per county wind and seismic foundation requirements (don't ask - they are idiots). So all array frames we
DX Engineering sells Yagi-Mech which calculates wind loads for yagi elements. Generally, gravity is less stress than wind so you can get some estimates of what is needed for diameters and wall thickn
Roger, I just unloaded 35k lbs of machines and 10k lbs of crates and shuttled them to my shop, so been there done that re big flat bed truck partially blocking the street at the open end of my dead e
I machined an aluminum thick wall tube (Holobar) for connecting irrigation pipes together and threaded SS eyebolts into it. Without a lathe here are some alternatives - Use a hole saw to cut 3/16" th
one more alternative for guy attachments - DX Engineering resin yagi element blocks, available in many sizes and not too expensive. Put an eyebolt through both sides and its ready to go, insulated ev
In a recent new building I put a Ufer ground in the perimeter footing which yielded about 1000 sq ft of concrete in contact with ground. Since the slab is over a vapor barrier and insulation, there i
Conduit benders are one predictable way to bend hardline and I also have some 90 degree bend frames for half inch PEX waterlines. The PEX is easy to kink and doesn't like to stay bent so these are ma
A friend had PVC pipe fragments migrating out of his face for years after a rupture of the PVC pipe these gadgets are made from. His "event" was a potato cannon failure, but there isn't much differen
Chris, KF7P makes arms with free sliding loops and also with hoops that the coax is tied to. see http://www.kf7p.com/KF7P/CoaxArms.html The hoop design keeps the coax from kinking, keeps it on the to
You really don't need a thrust bearing with a tower that has a sleeve. The sleeve takes the side loads and the rotator the weight. The mast will rotate freely if straight and if the rotator is aligne
I agree with Bryan, properly applied Loctite works extremely well. I attended a short Loctite seminar (nice cause they gave out lots of samples) and learned that generic Loctite "cures" when oxygen i
I just bought a quarter mile of bare solid Al electric fencing wire for elevated radials, 13 gauge for about $55 for 1320ft. It is available in 11.5 to 18 gauge, check Amazon and ag supply stores. Th
Dave Leeson W6NL, in "Physical Design of Yagi Antennas" (check Amazon) advises that trusses should resist sway in two planes - horizontal and vertical. Wind up/down drafts can cause as many problems
It's easier to stick to a 2" OD. I went with 2" OD but with a 3/8" wall 4130 chromoly. The cost difference between 1/4" and 3/8" is not significant. I want to make sure the mast outlasts me! Attached
For safety reasons, it seems like a good idea to support a laid over tower by more than the erecting cable when working on it. One reason is the erecting system load (mast and cable) is the highest w
