    It would be more exciting if you were 50 ft under water when the threads separated. How fast can you surface without getting the bends?

      PDQ from that depth. A buoyant emergency ascent at worst so a second or two. It's mainly a function of time at depth that causes the problem as nitrogen dissolves in the blood and then forms bubbles if there is more than can stay in solution at the reduced pressure. Much worse would be that the explosion would have happened pretty much right behind your head - potential projectiles pointing away luckily... almost like they've thought this stuff through!

      • I should probably turn in my man card, I've been sewing. Made a dress for my daughter for Halloween, now practicing other garments for my wife, in the name of learning a new skill. Probably going to start making my own clothes, sick of paying a fortune for ****ty materials in ****ty clothes.

        • Sew right on RB211. The best suit makers I've known were mostly men, except for my late Aunt Louise. She was a master at it.

          I spent a few hours on each of the past few days, dismantling the Jacobs RubberFlex Collet Chuck that I got as a bonus when I bought my mill. It has an LO mount which is useless on my D1-4 lathe spindle, so it has been sitting on a shelf for quite a while. Also, I discovered early on that it was locked up with a collet in it, which further relegated it to storage. Now, making space in the garage shop means getting rid of non used items, so time to fix or trash the chuck. No amount of monkeying with it would allow the hand wheel to move, so a tear down was in order. Got lucky and found disassembly and assembly instructions on line. Got it apart, cleaned and degreased all components, re-assembled and lubed it, gave it a little polishing, and now it good to go to a new home.

          In case anyone is interested in what had it locked up: Someone had it apart before and when put back together, installed the ball bearing loading hole disc upside down. That disc has a tit on it that I think may be an anchor point for the wire clip (disc retaning ring in the drawing) that holds the disc in. With the tit facing inward, it interferes with the loose balls and locks the mechanism up. Just a guess, but the tit is beat up from trying to force the chuck to open, and the wire clip was all bent up and had to be replaced.

            • Finished and installed another shelf rack for tool holders for the Tormach. This one is larger and unlabeled for all the "once in a while" tools and drill chuck's.

              Made softjaws for the 8 inch vise on the Hurco.

              Cut 4 more molds of a fifty mold order. (1st setup)

              Designed and cut an odd sized hinged blank for a semi custom lead bait mold.

              Worked on isolating a bug in CamBam when engraving using multiple work offsets. Found a work around that will save 46 minutes machine time per unit on that 50 mold order. Still have 39 left to go. Well 50, but the back sides will go quick.

              Worked up some standard styles for my style library for the Hurco.



              *** I always wanted a welding stinger that looked like the north end of a south bound chicken. Often my welds look like somebody pointed the wrong end of a chicken at the joint and squeezed until something came out. Might as well look the part.

              • Unusual lamps and lampshades and electrical question.

                I made a pipe bender and it is standing idle so I thought I would bring the creative side out of me. (something that is seriously lacking in me)Does a lamp need to be earthed. ?What if it is a steel lamp and the wires come loose inside the lamp itself, maybe they fret through with movement.

                I thought let me make something with my bender and do domething that would be different.So I found some pipe and an old gatevalve.

                Then after many hours of fighting with my pipe bender because its not user friendly and I dont know the formula for bends I came up with this.

                I was very proud of my creative genious and showed my wife all beaming and the first thing she said is "That thing is NOT allowed in the house."

                It hurt so now I have an unusual lamp for my garage. I need to make a shade for it so I was wondering what I could use that would be different.
                I have to say Im scared to turn it on and off cause the wires dont fit nice in the tap.Hence my earthing question.

                  No. Lamps are commonly made with their wires running inside steel tubes. And with 2-conductor no-ground cords. I'd guess that the rational is that there is no movement of the wires that could cause abrasion.

                  Add a touch of more coolness to your lamp by making the gate valve the on-off switch.

                  BTW - I don't get larger images of your pictures when I click on them (even though hovering over them brings up a "Click for larger image" message). And your emojis don't display.

                  • plunger I'll prefix this with the obligatory "I'm not a qualified electrician but..." my understanding is that if the case could conduct, it must be earthed. For a given definition of "must" depending on where you live and whether you want to stay that way Personally I'd get the wiring to the state that I was happy it wasn't going to ever cause a problem....and then earth the frame anyway.
                    As for the wife issue, you at least now have the ultimate defence if she says "Well you never make anything for me/the house”!

                    • I had apart the coolant pump on my FP2 and it was in really good shape. About the only time I could have said that for this machine.

                      • fixed my daughter's Fitbit watch thing, replaced the microUSB socket on a little battery bank thing and nearly melted the motor in a little "Swiffer" vacuum cleaner by seeing if 3 LiFePO4 batteries in series would work in place of the 9V NiCd POS battery. It worked great until the motor started smoking and the solder started melting on the connections

                            • For the lamp, it might be good to wrap the wire (zipcord) with some tough flexible tubing. Or make sure it is plugged into a GFCI outlet. Is that a touch sensor switch shown in the video? A low voltage LED lamp is another safe option.

                              Today I got 26 concrete blocks, which should be just about enough to build the shed foundation. My 1989 1/2 ton Toyota P/up made some funny sounds with that load. I estimate it was about 900 pounds.

                              On Saturday I went on a hike with some people from the adjacent neighborhood, to the Merryman graveyard and various old stone ruins, dating back to the early 1800s.
