Knuckle Buster Replacement
I have a single-action sheet metal punch, punches holes from 3/32" to
9/32". I think I got it at Harbor Freight. Whilst adding some extra holes to the frame of this work-bench I am building I royally busted up my knuckles. Is there a multi-action device out there that has real pressure multiplication? ...Jim Thompson -- | James E.Thompson, CTO | mens | | Analog Innovations, Inc. | et | | Analog/Mixed-Signal ASIC's and Discrete Systems | manus | | Phoenix, Arizona 85048 Skype: Contacts Only | | | Voice480)460-2350 Fax: Available upon request | Brass Rat | | E-mail Icon at http://www.analog-innovations.com | 1962 | I love to cook with wine.

Also, the deep thoat means your knuckles are a lot further away from the sheet metal. Warning: The set of punches it comes with are slightly weird sizes, and the extras you will want aren't cheap. One plus of the bigger one is that it can use D-hole punches for BNC connectors. Doug White |

Bent the wrench, but got the head-bolt loose. Took it back to Sears... the clerk smirked and handed me a new one :-) At least you got away with it. Years ago, I was jury foreman for an industrial-accident case... a guy used a pipe cheater-bar on the handle of a wrench when operating a sticky valve, the wrench handle snapped, he went flying and hurt his back. He was suing the maker of the wrench (claiming it was defective and should not have snapped) and the installer of the steam boiler on which the valve had been installed (claiming that the installation was faulty, placing the pipe and valve in a location where the use of a bent wrench was necessary to operate it). We found against him on all counts. The steam boiler had been repiped by somebody else, years after installation (which was when the piping was messed up), the wrench had been bent (no evidence at all that it was weak or defective when originally sold), and the injured man shouldn't ever have been operating that particular equipment due to seriously inadequate expertise, training, and literacy (he was in the habit of "lubricating" the sealed valve by spraying its exterior with WD-40... right around a gas-fired boiler... and testified that he understood the word "inflammable" to have something to do with maintenance). I felt rather sorry for him - he was pretty clearly in pain (although probably not as bad as he was making out to be - he failed a "trick test" by the medical evaluator) but was suing the wrong parties. Probably couldn't sue the party who was really responsible - his employer - due to Worker's Compensation law (he probably wanted more than Worker's Comp had paid him). Seeing this situation from the sidelines led me to promise myself that I wouldn't use cheater pipes on wrench handles! -- Dave Platt AE6EO Friends of Jade Warrior home page: http://www.radagast.org/jade-warrior I do _not_ wish to receive unsolicited commercial email, and I will boycott any company which has the gall to send me such ads! |

Is there a multi-action device out there that has real pressure multiplication? ...Jim Thompson I have one of those. Better than sliced bread... Used to be the "Whitney-Jensen" later the "Whitney-Roper" punch. Mine is circa 1965 when I got it... Invaluable tool IMO for making distortion free holes in thin stock (ever try to use a hand drill to make holes in a tin can?) The original came out with a bench mount attachment so you could spare your knuckles, but it was inconvenient and didn't sell all that well. You might try making one - the downside is that it makes changing punches and dies a hassle, ditto clearing out the slugs. I find it just as easy to clamp the metal to be punched between the die and punch then move it over to a low workbench and press down on one handle while the other is on the bench. A center-punched dimple makes finding the exact spot easy by putting the punches locating tit in the dimple while you move the whole assembly around. That punch, a "nibbling tool," "sheet metal" pliers, bench vise, and a hand reamer, metal file, and I have everything I need for metal chassis or mounting bracket construction; fast and easy. |

They has several 2" to 3" sockets that they used with a three foot 'cheater' bar. About every third try, they would just bust the socket. Every week or so, one of the guys was sent to Sear with the busted ones, and came back with new ones. Those thing went for $30 to $50 dollars apeice! Charlie |

Every week or so, one of the guys was sent to Sear with the busted ones, and came back with new ones. Those thing went for $30 to $50 dollars apeice! Too easy. When I was in college, the material testing lab had a nifty torsion tester. It could twist a cylindrical test sample into a pretzel shape. When nobody was looking, I "tested" a 6" Craftsman 3/4" shaft extension, which eventually took on a spiral shape causing all the chrome to peel off. Plenty of teeth marks in the grip area. The extension was rated for about 250 ft-lbs maximum. I think it yielded at about 3000 ft-lbs but don't recall the exact number. I then took the remains to Sears and demanded a replacement. After useless discussion about abuse, and several attempts to extract from me the real story of how I destroyed the shaft extension, I was blessed with a brand new replacement. The twisted extension was on display for several months at the Pico Blvd Smog Angeles Sears store, until someone apparently stole it. Sorry, I couldn't find any photos. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |
