    Designed a new wheel and wear testing the prototype.

    That is a great looking little device. Makes me think of the old train engines, though in reverse.

    What are the new wheels? Are they still delrin plastic, or some other material? While I am ok with the performance of my router at the moment, the most flexible part so far is the wheels. So having a better option that can still run on my C-beam rails might be worthwhile.

    I had some self lubing bronze wheels machined

    Very interesting. Please keep me posted on how it goes. If it works with your long term wear test, I might like to get some bronze wheels from you.

    Nice apparatus but without the wheels carrying some kind of load I have to question the validity of the outcome. An unburdened wheel should run pretty much indefinitely.

    I have a fairly heavy preload on them

    The problem is how do you quantify preload? Is it 2 pounds? 5 pounds? What?

    You might consider tipping the apparatus sideways and hanging a 10 pound weight on it (5 pounds per wheel) and that way you can show these wheels are good for say 50,000 cycles at a 5 pound loading...

    (Not aiming to criticize here, just wanting to see results a little more in line with scientific methods.)

    Well we'll call this a control test then :)
