  • I always wondered what that little hole in the Bridgeport was for.

    I found a use for the other side of the Bridgeport. At my age, with a very bad back, I can't lift my RT or my Diving Head.

    So I welded up this little crane. I know I could have put more support between the arm and the vertical stand, but it works fine for the weight I am moving.

    The "V" wheel is something which is easy to find here and is used for making rolling doors for entrances to houses and buildings.

    Here, everyone has a wall and bars. The local joke is that the criminals run free and the good people all live behind bars.

    I pressed out the shaft of the "V" wheel and threaded each side, then pressed it back in. What a soft gummy metal what was!

    I then used a slitting saw to split the nuts in half so they would fit on each side.

    The toy chain hoist is a Harbor Fright special supposedly rated for 500 pounds. It lifts well, but you better hold both chains together

    when letting it down or it will get away.

    I like it. I also am getting weaker as the years go on. That looks like a nice setup. I like your shop also.. What surprised me was that there is a harbor freight in Brazil. Thanks for posting. JR

        There are many attachments that Bridgeport produced that mounted in the back, the spline attachment is likely the most well known.

          For mounting a cherrying head or a slotting head.

            I knew that, but I thought it would be more fun to not know.

              I do get to the US at least once a year. On the way back the suitcases are always quite heavy for some reason.

                Why is it that most home shop guys
                seem not to be able to weld
                even a wet booger to a frozen mailbox?

                Nice crane build.

                      Not to rain on your parade, but grab your umbrella. Can you say "SNAP"! Say it real loud.

                      That looks like an awful stress riser point on the bottom of that CI bracket. I would add a counterweight to the back end of the boom. Today, not tomorrow.

                      But it does look like a nice accessory. I need something like that too. I am thinking about a storage table with an elevator top and a small crane at one corner.

                      And if you look REAL close at an analog signal,
                      You will find that it has discrete steps.

                        Paul, I agree with you. Hope the Bridgeport isnt disabled when she goes

                            I would think that the impact forces generated by this slotting attachment are much greater than the ones from lifting a rotary table.

                              A good idea assuming it can swivel sideways. I would add a balance weight on a rear extension to reduce the strain by half although that casting looks like it could hold a couple of tons.
