    1000 bar or 15k psi hydraulic manifold.. new parabolic drills from Walter worked very nicely. (4mm dia and 330mm long bore drilled from both ends.)

    • RE: For all you old rodders out there maybe this will bring back memories!
      Memories for sure. In 1962, I put a Hurst shifter in my '57 Chevy, 1970 did the same in a 64 corvette, and come to think of it, the original GM unit is still around here somewhere. (wish that car was) I also had an Ansen Posi-shift in a '56 Merc that was one of the first shifters marketed by Ansen in 1960.

        Yes Jim, this is my version of a Puckle Gun. I have more pics of this in the gunsmithing section. I built a proof of concept table top model in .57 calibre then scaled up to 40mm rifled, as i have some WW2 anti-aircraf barrels laying around.

        • I must confess I knew little or nothing about Mr. Puckle's gun. Pretty amazing for a design from 1718. Your workmanship is a fine tribute to him and the early machinists that built those guns back in the day. I look forward to seeing the firing mechanism. thanks, Jim (I got a chuckle from "i have some WW2 anti-aircraft barrels laying around...)

          • Thanks Jim,
            the table top model is a firing gun and uses a percussion cap ignition system of my own design. Each chamber has a copper band that covers the vent. When a chamber comes into firing position ( into battery, as we cannoneers say) the band is rotated to expose the vent. The copper bands prevent stray sparks igniting the other chambers accidentally. The 40mm version will have a bronze band instead of copper. Click image for larger version

            • 40mm = bofors AA gun barrels? That's cool - how did you end up with them?

              mattij - that's some impressive deep hole drilling that's for sure. Had a chance to pressure test it yet? I remember reading your thread somewhere about issues you were having with the previous design.

              here's my contribution. Made a mounting plate and pull knob for the hi-low-off main beam switch for a friend's '57 F100 restomod. He said it was a decent switch but came with nasty chromed plastic accessories which stripped out. Made the replacements bigger and better out of alu.

                  I cut it off twice; it's still too short

                  • Just needed to use a old grinder and a DA sander with different pads and had to make a couple of adaptors to fit the tools. This was my first successful job of single pointing threads, and I have to say I'm quite pleased with myself and the end results. I do have to confess though that the internal threads were done with a tap. Still learning with each project.

                    • Customer ordered 6 sets of stainless parts(mostly lathe work), these parts fit together and are roughly the same dimensions. I made 1 set on Mon and Tues.for FAI. This took 13 hours.
                      As I was leaving today the Boss said the good news was that the parts passed inspection, the bad news is that they want the other 10 parts Next Week.

                      These parts begin as 5" dia. X 6 3/4" long solid round cuts weighing 37 pounds each, they finish at 6 5/8" long and weigh less the 10 pounds each, this is a good deal of metal removal.
                      This is a family of parts, same design in different sizes, the new part has a 3" NPT thread.

                      This is a 2" NPT size of the same part.

                      • Now we know why you get paid "The Big Bucks" ๐Ÿ˜Ž I really like making ONE item, it's all those repeats that I hate. But then I'm the boss in my shop and Repeats just don't happen. ๐Ÿ˜Š

                          12 parts is not production by any measure (-:
                          I never make more the 20 of this family of part at a time, very limited demand I suspect, I have no idea what they actually do in use.
                          This is a small one with hose barbs for what I imagine is 3/4" ID flexible hose rather then pipe threads. All the angle features remain the same at 52 Deg., likely some sort of clamping device.

                            • One thing for sure, I'd bet that set-up for the ditcher shaft doesn't get repeated soon, Very cool.

                                Initially one fitting and one M5 end plug leaking, re-applied the thread sealant and now holds ~15k psi or 1000 bar without leaks.
                                Still bit unclear why the previous one persistently leaked and this one doesn't but hey it works..
