    New Never-Twist clamps

    John I turned down the threaded rod to 5/16" for about .750". Then, after turning the smaller diameters on each end of the "push/pull" part, I milled a flat on the "top" and "bottom" of the rounded section of the 7/8" steel rod I used for this part. Made the flats 180 degrees from each other of...

    New Never-Twist clamps

    John Insightful and, in the case of your No. 4 - most interesting! Here are some specific answers: 1. Yes - only the "standoff" pins are peened. All the rest need to rotate. 2. Yes - held by the peened standoffs. Note that my redesign has added an extra pin in each arm to make this a lot more...

    New Never-Twist clamps

    Just finished making some of the larger arms look nice, using a 1" abrasive pad. One new image shows a pair of the short arms - one as it comes from the fabricator, the other after using the abrasive pad. The second new image shows a complete set of the arms after treatment with the abrasive pad.

    New Never-Twist clamps

    This summer I have been designing and building my own version of Kant-Twist clamps in 3 sizes - 2.5", 4.5" and 6". I have the 6" one finished and will include pictures. I am happy with the design and have learned a lot from the process of building my first clamp. I had a decent quantity of the...

    2x72 sander

    I have started to build a grinder like this. After watching a lot of videos on the Internet, I decided to go with the Houseworks design - the Revolution 4 I think Brian calls it. I bought an air belt grinder for taking out the welds inside the square tubing. My compressor is not up to a...

    Best wishes for a speedy and complete recovery. Trick is to do enough exercise, but don't overdo it.

    Inconsistent fit - R8 collets

    The frustrating part about that idea is that I could not find a definitive statement as to the diameter of the end part of the R8 collet. One says .9500, another says .9490. I think I also saw one at .9485! That's the great thing about standards - you have such a choice! I realize that by...

    Inconsistent fit - R8 collets

    Today I read some more about this issue, and discovered a link where someone thought the problem might be the slots - but wasn't. Their solution was to reduce the diameter of the R8 collets that would not fit using abrasive in a lathe. I tried this and it worked! So, my problem is a slightly...

    Inconsistent fit - R8 collets

    Thanks Peter - that is helpful. Tomorrow I will carefully measure for any relevant dimensions for the slots in the R8 collets I have already tried. Some of those work, and others do not. For the sake of clarity, let me say that all of the collets go into the spindle way past the first encounter...
