Viscous Dissipation
Chinese Pulley:
$2/US Stainless steel. Fixed centre shaft. Single pulley wheel rides directly on shaft, e.g. no intermediary ball bearings. M2 (? Chinese) rating: Guesstimate a working load around 100lb. max for practical eyeballing (at the pulley) - probably advertised for twice or more that, more purely for body construction or what it'll hold. Maybe 300-400lbs. Actually kinda nice for a solid 3"-ish construction. Made an overhead cable attachment for my iron channel lifting cage. Some spare, different chain lengths, some threaded through cut rubber hose. Secured links with nuts and bolts. Main cable is 3/8" strand-and-twisted nylon rope, clothes-line or near to. Total cost to me so far: the $2US Chinese pulley. 70, 80lb. abdominal crunches and triceps extensions, forcing much more, 100lb. is where it begins lifting, tilting the front of the 80lb.-ish power cage towards, over and onto me. Pulley squeals, up to like a stuck pig, at dry. WD40 lasted once, a session, as does penetrating spray mechanical oil. Motor oil does better, 3 or 4 sessions. Which is as far as I've got. But that's all, besides and mostly, nasty. Sweat and a towel are enough. Any more, motor oil, is near to totally unacceptable. Had a hunch solid grease might surface, though, I've a tin of it, except I remembered a tube of food-grade, presumably lithium high-temp solid grease I'd use on a roaster for coffee beans. So I used a small, 3/8" wide utility razor to stuff the grease between the pulley housing, as much as I could get in there, from little play at the sides of the pulley, to lubricate the shaft and pulley edges for contact at opposite housing sides. Which is where I'm at. Any further, I just don't know. Silicon grease or dry lubricant graphite powder might be the breaking point, where I say screw it, go back and buy another pulley with a different design (non-fixed or nut-&-bolt secured pulley shaft). Provided of course doesn't raise the price of Chinese pulleys to commiserate $50B/US, made by the rich for the rich. Apparently, what I'm thinking after noticing is that centre-bearing "kits", ball-bearing-load are the regular, inexpensive item also on the menu for the Chinese pulley crowd. Sold for packs of 10 bearings. I guess Chinese also have issues with the Squealing Pig. |

I actually bought the pulley, two as a pair, and don't want to get over my head by mounting another, at my feet, for going the gamut of exercise movements overhead and down, adding another length of cable for optional attachment, to start another group of exercises from down and back to all the way up. As if vinyl-coated steel cable is going to be the icing to a cupcake of two squealing pigs then singing in concerto. |

Maybe I'll drop by and we'll do some 450lb. deadlifts. You really do sound like a such nice guy to have screaming at me. |

No, No, not screaming at you, 375 lbs was my limit, many, many years ago, Now retired, I'm 84 no need to work out. Rene |

Garage door openers (Chamberlain, possibly many others) employ a combination of cable and chain drives, with several cable pulleys. These seem to work (forever)on garage doors, but spare parts might be available at the big box stores like Home Depot. |

But, really, at least I can hope to still be lifting at 84. I've only known one pretty near to that age: An Austrian or German, Bona-Fide Carney Strongman Showman. Hell'va nice guy, about 6'2" and wide as a house. He'd been a lifter all his life. Also met a state champion deadlifter, late one night in a key-club, I watched rep'ing 5x450lbs for his warm-up. That 450lb'r, I'd put the Olympic bar clips on the cage facing outwards, slightly below where my wrists naturally fall, feet shoulder width. Standing inside, leather wrist straps, I first lean into the bar, lifting the 450lbs by standing straight. Just enough to clear clips and no feet movement. -Then- the deadlift, lowering 450lb down to "legal" position and back up and bar back onto the clips. Belt, knee wraps over neoprene knee sleeves and wraps on the shins as well. Sort of a deadlift and half. Nothing legal, though. 375lb I can pull maybe times consecutively -- only on a really good day. 375lbs that's far better than a good start though. 285lbs. is where I put natural talent for just coming out of the gate fresh. More important than the weight, though, is taking care of the hip and knee joints and ligaments, back, and everything else about proper form. Gimme a high-five, Rene. |

These seem to work (forever)on garage doors, but spare parts might be available at the big box stores like Home Depot. Garage door spring is what I used for the securement block, (a spare dumbbell handle Wallymart tried to rip me off on Ebay by sending a single unit), which is where I slip on the olympic plates. Garage door spring, high poundage/ tensile strength, and the centre happened to be wide enough to thread onto a standard 1" dumbbell hand. Had to use a 100lb vise and leather gloves to twist the dumbbell handle, threading that spring deeply enough on the handle. Both dumbbell securement collars I left on the other side, one jammed and locked over piece of nylon ribbon wrapped around the threads. 2"-holed Olympic plates then slide on, (from the spring side), nicely to butt-up securely to the collars. I pulled, wedged up the length of spring, enough to form a partial circle where I can slip a chain length under and into. (Some heavy chain on both ends of the nylon rope). None of that is going anywhere, anyway, with two 35lb. Dick Sporting Goods Chinese Olympic plates slipped on. Ignore the dangers for a brief instant to close your eyes. Can you begin to hear that $2/US Chinese pulley beginning now, heating up, and rising in volume to a full-blown pig squeal? (Well, will first have to see if the lithium food grease "axle pack" holds and has permeance. I've seen one gym rat before break down and rejuvenate Olympic bars with lithium, in preference to petroleum derivatives. Even though swiveling snatch and curl collars are definitely not per se a cable pulley.) |

wrote: Yep, High-Five, Happy dreams. You're right again. I figured out the solution: There is none. Nobody wants to sell nickel-&-dime pulley blocks. It's a dream. If the "food grade grease" doesn't hold up, I'll just have to keep on repacking the pulley for as long as it does. Real pulleys, OTH, can be (easily) maintained, provided they even squeal in the 1st place. I found these... Factory 2nd's on Ebay for a steal. One is normally $40+, on this link being sold for $7.50 each. Except they won't sell less, direct from the factory, than for 20 units at $150 in a boxed lot. Way overrated, but that price is a crying shame. Damn good blocks... https://www.ebay.com/itm/Wholesale-L...-FACTORY-2NDS/ 122015629489?hash=item1c68b2c0b1%3Ag%3AeYMAAOSwq7J T0UG1&_sop=15&_nkw=pulley+ton&_sacat=184212&_from= R40&LH_BIN=1&rt=nc&LH_TitleDesc=0%7C0 |
