    4-axle front discharge ready-mix truck

    Where I come from [oz] the delivery docket quite clearly states "responsibility ends at the kerb",and the docket is a legal contract!

    Help, Dreaded cracks how bad will they get, what to do?

    It is my opinion that a vapour barrier actually contributes to cracking, the same as an overly wet subgrade would!Let me try to qualify! As you have already read other threads on this subject, I won't rehash too much, but I do find SCGeo's assessment interesting to say the least!If the...

    New driveway cracking like a potato chip

    ke6fx,I need to say it IS the contractors fault! The concrete mix is innocent! Everything that has been said is correct, however, if I could just put it into a bit more perspective.The cracking is shrinkage cracking [or alligator,although I haven't heard that term before, I'm from OZ] Yes, it...

    "Negative Steering" Please explain.

    Obssv, I hope that in the couple of days since your last post that you've had time to think a bit more about your theories! If not, lets work thru the first one. Steering head welded,cable attached to bike and a fixed point, bike perfectly vertical,now roll on the throttle and bike tries to move...

    "Rat Walls"

    A "Rat Wall" is exactly that,it stops rodents burrowing under a slab from the edges. They are effective if that's a problem in your area.The rodents burrow under and excavate big areas of fill from under your slab to make a "home", effectively leaving it partially...

    Permanent wearve from from end !!

    Not sure what that is! Do you mean the whole bike is weaving or are the forks misbehaving!Has it suddenly happened ? Just a thought, but are your wheels tracking properly and check that they are they both vertical, but the latter would suggest a bent frame!Other than your alcoholic content, I'm...

    Tyre profile, what effect if any on steering?

    Interesting! Had the exact experience a couple of years ago with a Yam 660 "Aventure Tourer". Did an "Outback" {OZ} ride with four others on the same bikes of about 2500 miles in 7 days.Because the riding conditions would be varied and unknown, I decided to set my bike to the...

    Tyre profile, what effect if any on steering?

    What effect does the profile/shape of a tyre have on steering a bike? For instance, my tyre is flat with rounded edges , and a sportsbike tyre is very rounded!

    "Negative Steering" Please explain.

    My last post may have been a bit confusing, but the spinning wheel was just a way of working through the gyroscopic theory put forward by Mowgli!I'm curious Mowgli, why your so sure it's gyroscopic, did you read it in a book? If so, and Metalguy is right, {pity his post was deleted}, then how...

    Half an engine number

    The Police used to have a way, maybe xray, to find out if a motor had been stolen and the numbers ground off. Apparently the number punch compacts the cast iron below the imprint and the xray can detect it.I'm not sure tho wether it was just one of those urban myths!!

    "Negative Steering" Please explain.

    There is a gyroscopic action called"precession"{which Mowgli may have been alluding to} which basically means that when a spinning wheel{gyro}, has a rotational force applied to it, ie. turning your front forks,which is working in a horizontal plane, the wheel{gyro} will react by...
