  1. Both:

     

    Even if you don't insure a package you can have it tracked for just a few bucks. Seems like some good communication would solve all these problems and that probably starts by leaving the accusations out of it.

     

    Seller:

     

    It's highly unlikely that someone trying to dupe you for an extra free part would start a thread on it in this forum, so if he says he hasn't received it its not only likely to be true but it's your obligation as the seller to repond to him in a timely fashion. And give him the tracking numbers even if they are to the border at least you giving him some information. Why would that be unreasonable?

     

    Personally I would never ship or buy internationally without tracking. Obviuously you're not saving any money.

  2. MH427 - You'd be correct sir.

     

     

    Indeed spawns of Sbarro, the famous italian stylster and promoter of the hubless wheel, turned mall foodcourt pizza magnate.

    Sbarro foisted his squeezed blob creations on us for 20 years before being ripped off by the mainstream auto industry and other countless other horrors of institutionally plagiarized ingenuity like the apache and the godless hubless chopper crapsters vomited out by the aftermarket, while he continued to spawn other nameless and pathetic creatures. The true challenge always was: is it shite or is it Memorex...?

    Yeah, see, all shite and actually true Memorex...but here's an unaccredited non-sbarro "tribute":

    Wow...hubless...and still crap.

     

    To his credit, Sbarros never shied away from allowing the full inspiration of jellyfish, squid and seemingly countless other invertebrates to influence the design of his rigid chassis sportscars in a bloodless visual assault on the basic sensualities of form passionatately meeting function. Depending on your design viewpoint...you may or may not enjoy his designs, with the caveat that if you like them you are clearly incorrect...

     

    For the record the Italian designer actually has nothing to do with the pizza joint.

     

    But hey... I'm cool with it and it's all good man.

  3. It's a good approach Blueovalz, but try flipping the slip rings around and re-installing them. I also have luck rubbing the the slip-ring against a cat before installation.

     

    Or try the Chafer modification mentioned in my last post.

     

    Good Luck.

     

     

  4. The topic of grip and friction is a tricky one.

     

    Tire compound, as you know, is created primarily from two materials, styrene and butadiene. Because the styrene molecule has a vinyl group with a double bond, it can polymerize. It is used as a monomer to make plastics such as polystyrene, ABS, styrene-butadiene (SBS) rubber, styrene-butadiene latex, and unsaturated polyesters. All are created from petroleum.

    Polyester and Kevlar is used to give the tire strength.

     

    How these factors affect traction and grip is obvious to anyone who has ever received a shock walking across carpeting. The polyester in the carpeting and the latex in your shoes interact to create an electrostatic charge that builds current in the body giving you a shock when you touch metal. The same principal is at work on the road where petroleum products from the tarmac (a negative charge) and the reciprocating tire compound (generating a strong positive charge simliar to a spinning planetoid.) are attracted to each other pulling the soft rubber compound by electrostatic attraction into the surface defects of the tarmac. Losing adhesion is therefore called breakaway because these smaller rubber nodes are sheared by the lateral forces and immediately lose charge thus destabilizing the attraction forces between the tire and the road surface.

     

    So why, as JohnC postulated, do wider tires have more grip? As you have already no doubt surmised, the larger tire acts as a larger electromagnet generating a larger positive charge. This in turns creates a larger field of attraction with the road surface. You can see in the diagram below how the concentrated compound in the tread are would focus the positive charge through centrifugal force tossing positively charged electrons aginst the road surface thus creating the grip.

    By carefully hollowing out the chafer area and installing #9 resistors you can significantly stabilize the electrostatic characteristics of the tire and thus maximise these grip creating qualities. Every racecar driver knows this secret...except for GT drivers who discount the adverse effect that rain has in dispersing the attraction field. They, of course, are ignoring the mighty #9 at their own peril.

     

    Hope this helps.
