q for SusiJ or anyone else who knows a good supplier for dial guages?
I want to build a wheel jig, partially for truing, but mainly to measure deflection under load so I can test wheels for stiffness. The plan is to make a horizontal "fork" of sorts out of unflexium very-stifforundium (probably a couple of hunks of square section steel), that I can pop an axle into, put a standard tyre & tube on the wheel, inflate to a standard pressure and then hang various weights off the rim with a hook and measure how much the wheel deflects with a dial guage. I'll also weigh each wheel *with* its supplied skewer. I'll try and review every wheel I get my hands on and build up a (free) database of the results. I'm sick of the useless "it feels stiff" crap that gets published in the bikeporn mags and want to have some hard data. The cranks test in the latest Ride is a step in the right direction, but no-one that I know of is doing this sort of testing on wheels. Most of it's pretty simple, but I have NFI as to where to get a good dial guage from, and google hasn't been all that useful (about 30 mins or so of looking, but not really having the right keywords I think). This was the best I found : http://cgi.ebay.com.au/Magnetic-Base...cmd ZViewItem but maybe there's something better or more suitable around? any suggestions? |

I would also look to book "the bicycle wheel", which did a lot of this
sort of testing, obviously the wheels used would now be different but the approach is very academic and is likely to explain the testing methodolgy as well. |

Yeah, good idea. I've been meaning to add that one to the library for a while. I've got "the art of wheel building", but it's a bit touchy-feely and lacking in any hard analysis. |

On 06/03/06 at 15:22:41 Bleve somehow managed to type:
snip but maybe there's something better or more suitable around? any suggestions? RS Australia in Salmon St. Port Melb. sell a bit of that sort of stuff. Have a look at www.rsaustralia.com - all products - tools/storage - inspection/measurement and I'm fairly sure you'll find what you're after. Alternatively just go to http://tinyurl.com/j9weu -- Humbug BE A LOOF! (There has been a recent population explosion of lerts.) |

Lots of 2nd hand ones at
http://www.pcwi.com.au/Secondhand-Used-Equipment.asp. That was the third hit from searching Australian pages for "dial gauge" at google com.au. "Bleve" wrote in message ups.com...

All my good tools are Kincrome and I rather like them. Tempting me into buying more is evil. |
