m... JP has found his level, it's between about 15th and 25th (on a good day) when all the top crossers are there. I highly doubt he's going to have a big jump in ability all of a sudden and be riding at the front of big races. I suggest that this is exactly what it looks like when some unknown comes up through the ranks. Lance came completely out of nowhere. |

"Howard Kveck" wrote in message ... Sure, you could make those (if they're similar to the ones I've seen on other bikes - it is a replaceable bolt on bit, right?) on a manual mill. You can do a lot with a mill and a grinder. But I'd still rather CNC them. You can draw the piece and make a program in a few minutes, set up the tools and machine and make a few in a big hurry. snip What sort of machine you use? And program? Solidworks? |

"Howard Kveck" wrote in message ... The thing with this issue is that the hanger he's using is obviously underengineered in some way (and since I haven't seen it, this is speculation): some of it could be too thin or there might be a sharp corner on the inside of it that creates a stress point where it bends if the bike crashes. Dumbass - You are right about it being underengineered and making that conclusion about a part that broke 7 times in a season by 1 person is not really speculation. |

The shop I work at has a few Mori Seiki VMCs and some smaller ones by Fanuc, and we have a couple of horizontals, too. We also have a few CNC lathes. The thing is I've been running that stuff long enough that I tend to still use them for manual type work. They have dials that you can use to crank the table over to where you want or I'll just write a quick program that tells it where to go. When I started out in the trade, we didn't have a CAD/CAM setup that everyone could use so I had to learn to do things at the machine with a calculator and some trig formulas. And program? Solidworks? We use Mastercam. I haven't spent a lot of time doing 3D stuff (because it isn't called for that often on the parts we make), and that's one of those things where if you don't do it on a regular basis, you forget the tricks that make it easy. That's one of the complaints I have with this job: the parts we do aren't particularly interesting or challenging to me. -- tanx, Howard "I'm not lying, I'm writing fiction with my lips!"

Well, yeah, but what -was- speculation were the reasons I suggested (should have been more clear on that). I'd like to actually see the part. -- tanx, Howard "I'm not lying, I'm writing fiction with my lips!" Homer Simpson remove YOUR SHOES to reply, ok? |
