DIY Felt Roller Build, Pt. 2 – The Bill of Materials

J. Matthew Phipps | July 6, 2014 | COMMENTS:2 Comments »

As promised, this is the “Bill of Materials” for the roller. The U.S. cost was a little over $400 (US). I tried to eliminate some of the prototyping costs from this list, for instance, my abortive attempt to use a sewing machine motor (hint: it worked fine, but then under load it began to smoke.) You’ll note, I did try to do a metric conversion, but then a looking at lumber discussion boards I began to realize that it is not as easy as just converting the numbers. If you have suggestions, please send me your input.

For builds in areas that aren’t 120 VAC 60 Hz, you’ll want to adjust your searches on Ebay, Amazon, or whatever you use locally for auctions and purchases. If where you live is like the U.S., then you probably have a neighbor who has a treadmill that they will let you have for free,  “if you will just please come and take it away” so their wives will stop bothering them about it.

I will post about the motor and controller box next.
