    Default tube grinder

    I needed something to notch tubes that were hard to hold in a vise. The commercial tube grinders run from 3K up!!! Looked thru the scrap pile, ordered some bearings and pulleys, and slapped this together. It is a real timesaver and will get a paint job soon...

    Default Tube grinder...

    Hey SNAFU,
    Hmmmm...You must be ex-military...

    Nice setup...looks like it will really hog off some material. I use those kinds of belts at work also....love those 20/30grit belts. I noticed the vertical Allen-head bolt....is that your belt tensioner? Think I'll make one for some odd jobs I do on occasion....Thanks....Denny

    A local chassis shop just rounds off a grinding stone on their grinders with a dressing tool. I copied their idea and it works great.

    They were turned with a crown to the middle so the belt would track right. The middle roller is on a spring loaded arm that makes changing belts easy. I get good life out of a belt, really surprised at how well they hold up.
    Thanks for the compliments, I will post some pics after painting.

    Great job, just wondering how many hours you got into the machine work involved. We use a tubing notcher on our stock car roll cages but this looks like it may speed things up a bit. Guess I gotta try to build one like it now. Dave
