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
Do you work for Ikea?
It's just that Ikea used to have all these Rube Goldberg contraptions for testing furniture, your setup just reminded me of those is all.
It was a joke...
HaHa no worries
