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.

Building the DIY Felt Roller, Pt. 1 – Driving it

I’m going to start this series with describing the most technical part of the build, even though, it is really the last to be attached.

First, a failure: I tried using a sewing machine motor that I had salvaged from one of my mother-in-law’s sewing machines. When I first turned it on, it did fine. I then put a felt project into it and the motor burned up. It did not smell good, either. This started my search for a good motor with enough horsepower. I settled on trying to find a treadmill motor. The motors are 120 VDC in the U.S. I looked around and found quiet a few used, but still working, motors on Ebay.

In the U.S., there are perhaps 25 different companies selling treadmills, but inside they all seem to be Precor machines.  The motor I purchased was well used, and came with the flywheel that has an integrated pulley wheel. This has turned out to be essential.

I also purchased the “front roller assembly” that has the other pulley. You’ll also need the belt. The big problem was attaching it to the roller. I’ll explain that later.

This is the motor control box and the motor. You’ll see the “mains” going into the side of the box and the DC leading to the motor. The controller box has the MC60 treadmill controller circuit board, a 20 minute timer, and a 5k potentiometer that controls speed.

The next post, I’ll show the controller board connection and post the Bill of Materials.

Felt Rolling Machine Update Coming

J. Matthew Phipps | June 16, 2014 | COMMENTS:No Comments »

Update: I haven’t forgotten. I just had a little business that interrupted. Pictures and details coming this week.

In the past couple of weeks, I’ve received two emails, one from Brazil the other from the Netherlands. Both asking about my felt rolling machine. So, I’m going to start posting about it. I’ll start this weekend.

DIY Felt Rolling Machine

I needed a felt rolling machine but didn’t want to spend a lot of money. The professional machines were either too big and too expensive or two small and too expensive. In future posts, I’ll detail how I built it, but for now, I’ll post some pictures and the more creative of you can deduce how it was done. Of course, I’ll be more than happy to discuss details.
