  • Third hand idea

    wanted to try something with pic's...here goes.

    occasionally I have to silver solder something, and holding the parts in alignment is a real pain. the commercial product below is worse that useless - complete POS



    so i made of the following. fairly simple, uses solid cotters







    the ball on the last one is for to-be-built arms (one day) the work surfaces are AL so SS doesn't stick and are thin so as not to be heat sinks. the small V-block is angle milled thin and peened onto the shaft, there's also a large one not shown. the larger black spring paper clips (if that̢۪s what there called) are good for clamping, although all manner of attachments could be made

    I Like it. Nice work. How about a photo of it in action holding something?

      Yea, I agree with gkman11, it all clean and stuff. What are you soldering together?
      Civil engineers build targets, Mechanical engineers build weapons.

          mac, nice job.
          usually when i solder it goes something like this:
          iron in right hand
          solder in left hand
          part#1 under my right armpit
          part#2 held firmly between my chin and chest

          don't know why, but when i move in with the iron, my two parts seem to move away from me, and i have to move in closer with my iron.. and they move further.. i have to chase myself around the shop for an hour to solder two parts together.

          but there is nothing like hardheaded determination to get a job done.

              ROFLMAO

              Too funny - I've done the exact same thing myself.

              BTW Mcgyver - Nice work. When I discovered cotters (split) I thought that they were the slickest thing since sliced bread.

                that's a great image. I can definitely see that. If I tried it, I'd be the crazy guy down in the burn unit with 3rd degree burns on 99% of his body. The doctors would all be standing around going "and he did it with a soldering iron!?!?"

                  Very nice work. Once you said what you were building I understood how you were going to use it. Again, very nice.

                    Mcgyver -
                    Nice work! I agree that the commercial product is a PITA. I usually wind up with a solution somewhere between yours and knuclehead's. I've made a few "one or two use" fixtures, but I've never just sat down and made a proper fixture. Gets me to thinking...

                    Oh yeah, and regarding that Other Thread - here we have solid evidence of Intelligent Design. (Sorry, couldn't resist)
