Once there was a guy who had a bounce free
hammer and I asked how it worked. He explained the little balls going up and down. I was terribly impressed by this. But then one day I used one myself and slammed it open and could see it all first hand. It was still a good answer but quite possibly that's the way he had found out as well. Somehow took the magic out of it. -- underground experts united http://user.it.uu.se/~embe8573 |

Huh. CFRP rims strike me as a solution looking for a problem, creating
new problems along the way. I suspect that I don't have the orginal problem that is trying to be solved (I am not racing the TdF and large sums of money aren't involved in the outcome of any of my bike rides). The exploding rims were kind of cool, though. Holy smokes. That would change change the outlook of your day. But I wonder, in the real world, how likely that would be. Even wiht long descents, it's unusual to have the brakes applied for minutes at a time (unless you don't know what you're doing). |

Or, you can make your own: https://i.pinimg.com/736x/ae/c4/b3/aec4b3b588620dcdf520590ffce00222--hammer-forging-war-hammer-weapons.jpg When I was an impoverished student, I used one similar to this that was lead fishing weights, larger size pipe, plastic caps, and a wood handle. When it disappeared, I found a bronze hammer, which seemed to work better than a lead hammer. I didn't have the facilities to recast a lead hammer so brass worked well enough. Years later, the plastic shot/sand filled hammers appeared, so I bought one of those and retired the bronze hammer. When someone stole it, I replaced it with a steel mallet with leather facing and a cheap soft face (plastic) hammer with replaceable facing for the light pounding: http://www.acehardware.com/product/index.jsp?productId=19377956&KPID=15216355 As for Learning by destroying". After a number of years of replacing bent, busted and broke eventually the penny will drop.... Read the F...ing Manual. First! Never. I consider reading the manual a sign of weakness. If my customers see me reading the manual, they would usually ask "do you know what you're doing?" or "am I paying you to read this?" I reserve reading the manual for after I'm finished, to see what I may have missed, or when I get into trouble. Besides, if the product were any good, it wouldn't need a manual. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

However, buying one (or a set) will need to wait until I destroy my current hammers. I don't use one often enough these daze to justify the expense and the home made leather or plastic facings are good enough to prevent surface damage during one of my violent tantrums. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |
