      Peter, the power hacksaw blade is about .050″ thick. Ian S C

        0.050″ thick equates to 1.27mm. So it is just under twice my normal hacksaw blades. Which means that they will be much stronger and therefore less brittle. Could be worth trying sometime if I can find a scrap one.
         
        Thanks Ian.

          When I first got my lathe, one of my first projects was a replacement set of radiator nuts for a Lanz Bulldog tractor, these were made of bronze 2″ dia, threaded 3/4″ BSP, so the 16 bits of bronze had to be parted off some how, and the bit of saw blade was all I had, it worked well, even though some one told me I might have a bit of trouble with it.

            Hi, Ian, off topic I suppose, but. I’d be interested to know how you clamped / mounted the parting off hacksaw blade, a simple description will do. I’m in the thinking mode for a different, and cheaper parting off tool.

              he holder is a bit crude, the part that fits in the tool post is made of 2 bits of1″x !’ X 1/4″ angle iron, the blade is held on a piece of 1/4″ plate with a recess a few thou less than the thickness of the blade and held against the angle iron with 6 1/4″ bolts, the holder is about 3″ long. There you are, as clear as mud, Imight try and get a photo of it, you’ll then see how rough it is. Ian S C

Ian S C PS I tried making a parting tool to fit it out of a bit of a Tungsten Tip cicular saw blade, but the tip fell of, I do on occasions use the little tips on lathe tools.

                  Thanks for that, think I understand, but not be doing anything for a few days. The septic tank has thrown a wobbley and wife says it must be fixed.

                    Hi Gordon, I won’t say anything about septic tanks, I’v got one, and its OK at the moment, so I’m not tempting fate. Ian S C

                      Hi Gordon,
                       
                      If you can get a look at Len Mason’s book, Using the Small Lathe, there is a line drawing of how he made his, and which I followed, suitable modified for my lathe.
                       
                      Essentially, mine consists of a 6mm x 30mm x 80mm plate with a slot machined lengthwise slightly less than the file thickness (in my case – for a hacksaw blade it would be just under the blade thickness) and then a 3mm x 30mm x 80mm clamp plate holding it together. Clamp screws were 6 off 4BA. On the other side of the 6mm plate is a longitudinal thick bar which fits under the toolpost screws and is set to get the cutting point of the tip as near as possible on centre height.
                       
                      Regards,
