  • Two Jaw Vice?

    I need to build a small vice that will center the workpiece when tightened.

    The maximum opening just over 2".

    I cannot figure out how to do it simply. I have figured out ways to do it but it becomes to bulky.

    This will be used as part of an attachment for my belt grinder to round the ends of material. The vice will sit on a cross slide type of mechanism in order to feed the workpiece to the belt as the rounding process progresses.

    The reason is so I don't have to drill a hole in every piece I want to round the end. The pivot will be under the workpiece.

    I have a self centering bar vice, so what you are looking for is made. I don't think it would be all that straightforward to make, so you might be better off just buying one. You should perhaps try a search on ebay, you might well be able to pick one up at a decent pice.

          Centering Vise

          You make a groove in the middle of the right and left threaded rod and a stationary U section in the base or hold the rod from moving at the ends. Once you get it all together, get the closed jaws centered on the pivot point and dowel pin the base with jaws centered.

            Here's an example of a commercial one, I would think you could pick up a used one for a lot less if you are patient. http://www.shars.com/products/view/5...g_Machine_Vise

              Another possibility for a self centering vice is a 4 jaw scroll chuck with two jaws removed....although that is absolutely no use for your job!

                That seems to be a pretty reasonable price.

                  BF,
                  I went throught the same drill wanting/looking to build my own centering vise. After much frustration, I found this one and made the purchase. It's quite a nice little vise, much better than what I was trying to make.

                    I made a PDF of what I want to build......but I can not upload a pdf to Photobucket. Any ideas how I can let you all see this PDF?

                      That vise from Grizzly might work!

                        Small self centering vises

                        wood working folks use a small self centering vise for
                        drilling pen blanks before turning. search for Penn State Industies
                        or any of the stores that sell pen turning kits and supplies

                          Thats why I switched to flickr. It creates BB code for the size of pic you want to post.

                            A brace and bit type drill uses one up to 1/2" but I never paid any attention to how it worked.

                              Either out-put the original file to *.jpg or scan the hard-copy of the *.Pdf file and out-put that as a *.jpg file.

                              Then up-load the jpg file to Photo-Bucket as usual.
