Power Drill to Belt Sander Conversion
Topographical Lake 3D Print
Excellent! I wish I had known that earlier. Using the curbs seems to be causing fraying on the belt. Not significant fraying but a few strands of the cloth fly out.
Ahem.- I put this under the 3D printer category.- My first sentence was that I spent all my money on a 3D printer.- The main picture clearly has custom plastic parts.- Shapeways will print parts for you without having to own your own printer.- Be nice.
Ideally you want to use "crowned" pulleys (or "belt" pulleys) when driving flat belts. A crowned pulley is convex, which counterintuitively keeps a flat belt centered and prevents it from wandering off the edge. You won't need those curbs at the edges to keep the belt on. - noahspurrier
When you enrolled into the "3D Printing Class" a few weeks ago, did you tell them it's a useless class because you'd need a 3D printer?I contacted a printer on Etsy, and have the parts being made. The guy making them even said he's doing one for himself... - kozmonot
A next to useless instructible."you'll need a 3D printer," What ! - andrewty
This was designed around 30" x 1" belts. Amazon has them and many hardware stores stock them.I needed the 1" width for a project where I'm sanding between the teeth of large plastic gears. If you wanted to try it with a wider belt you can take a look at the OpenSCAD code.
I suspect you're right about the rods getting wobbly. Maybe with reinforcement but that's practically a project in itself. I noticed that even this small version was prone to wobbling. Now if you could affix the vertical rod to a door frame or something sturdy it should keep it all in place.
Exactly, you get it!It was designed with modularity in mind. If you can find longer belts just lengthen the threaded rods. You could even run it with two pulleys instead of one.If you polish a knife with this design be sure to come back and post a picture here so I can see.
Most knife guys use a 1x72. I imagine the rods to get wobbly once they get so far out
What size belts is this geared to?
Cool. Thank you! I was thinking since it looks like the vertical rods and wing nuts adjust the tension. So if one were to lengthen those (and even the horizontal rods) the belt size could go up quite a bit... if that makes sense. I make knives and was thinking of making this for polishing. Was gonna use a treadmill motor instead of a drill
