That actually sounds like a design or maintenance flaw. First, limit switches should have stopped that. Second, the motor should not be able to produce enough power to break a lift cable in good cond
Just remember that not all stainless steel is non-magnetic (check your fridge door). Generally 300 series is non magnetic, 400 series is, but less so than normal steel -- 73 de KG2V Charlie _________

By in large, almost every ham item I see is under designed mechanically (not just towers). We get away with things because, well, we accept a certain amount of failure, and we arent willing to pay t
Actually, a properly done eye splice is the strongest way to put a loop on the end of a line, but is permanent. Preferably with a metal eye in it. For laid rope, I still prefer either a wall and crow
The ABOK is a great reference, but not the easiest to follow What I believe he did wasnt technically a knot ( I showed him a drawing) Make a bight in your line, and pass the bight through a ring, and
Put a clamp around the mast, tight against the thrust bearing to hold the weight, pull the rotor. If you need more clearance to slip the new rotor in, put a bottle or scissor jack under the mast at t
The problem with most sources is that shipping is the killer. As someone said, under a certain length (108 inches aka 9ft) it can go UPS, over, you are looking at truck. What we call CrMo DOM mast is
Ok, in prep to replace my rotor, get back on the air, and clean the shack, I have some questions re connectors, coax, etc First, right now, my rotor cable comes into the house, and goes right to my c
Not the same. I actually make an adaptor (and sell) The TX-2 is six 5/16 bolts, the Yaesu is 4 8mm bolts, IF your tower has slots every 90 dogs, and the slots are wide enough to to fit 8mm it will wo
45 degrees doesnt work because of the pattern of the TX-2 (which is basically an 8 bolt pattern, minus two bolts). You are best rotating 22.5 degrees, which puts you half way between the TX-2 pattern
They are known as a XRF gun, or a Metal Alloy tester - They cost in the ballpark of 30K-50K new. I see them on eBay for 3K-8K. They basically are doing X-Ray Floroscopy, hence the XRF -- Charles Gall
That K3EJJ design is what Ive been saying exactly what needs to be made, and I thought about BZ to him on that. Very nice. IF there was enough demand, castings would be the way to go, but -- 73 de KG

Cast Iron is interesting If you get good grade cast iron, it machines like butter If it is cooled rapidly, you get what they call chilled cast iron, which can be amazingly hard, like you either must
Indeed, 304 stainless bolts are roughly the same shear strength as grade 2. That said, through shoulder, single sliding shear is about 4900 lbs. Do you really need more than that? Sometimes as hams,
