Adam Savage's One Day Builds: Hellboy Samaritan Prop Barrel Rifling!

  • Adam has one final machining task to complete on his Hellboy Samaritan prop, and that's adding the interior rifling details of the replica's massive barrel. To accomplish that, Adam uses a custom tool called a broach, which needs to get precisely pushed through the barrel with a tremendous amount of force to make its cut. Adam has an idea of how to achieve that, and it's going to require quite a bit of elbow grease!

      20 tons might be about right. My "back of the envelope" calculation:
      3/8 inch bolt diameter = about 1.18 inch circumference
      1.18 inch x 18 thread pitch = about 21x mechanical advantage
      about 5 inch grip handle / 3/16 inch bolt radius = about 26x mechanical advantage
      about 70 lb x 21 x 26 = about 38,000 lb = 19 tons of tension on that poor bolt
      (if indeed Adam was applying 70 lb using both arms, as he estimated)
      I'm not going to claim this estimate has more than 1 digit of precision, but anything in that neighborhood makes it unsurprising to me that the bolt snapped.

      @nikitanugent7165 3 ปีที่แล้ว +10

      ​@@_Nanigashi I suspect a lot of that was simply overcoming friction. Fastenall lists their steel allthread as having 60000 psi tensile strength, which using the minor diameter of 0.3005 in results in a maximum tensile load of 2.1 tons (and I'm sure the stress concentrations in the thread make it lower than that).
      Home Depot lists Superstrut 3/8" allthread as having a maximum load of 1900 lb, which works out about right if you assume they're using a safety factor of two.
      Of course all we know is that 2 tons was not enough force to finish the job, though I doubt he was applying much more than that with the vice. (And more press never hurt! At least as long as you mind your limbs!)

      I wouldn't say lathe turning is a very common rifling method. Rifling is generally cut (single point or all grooves at once), forged with a mandrel (hot or cold), or pressed with a rifling button. There are also some less common methods, like electrochemical machining, which has recently become a rather practical way to DIY a rifled barrel.

    Probably already mentioned, but the big advance with the Minie ball was that it was actually SMALLER than the bore of the weapon. Previous to it, jamming a musket ball down a rifled barrel was difficult because it had to be the same size as the barrel to engage the rifling. It took far more time than loading a smooth bore. Rifles were used in earlier wars, but by specialized troops. Even with a musket ball, the spin imparted made them far more accurate. With the Minie ball (which was bullet shaped, not a ball), when it was fired, the base, which was hollowed out, actually expanded to engage the rifling. So easy to load, and still had the advantages of spin imparted by rifling. And deadly. Huge bullet with lots of mass would shatter anything it hit.

    This was just as fun as it was painful to watch. I appreciate that you show the whole process and don’t edit out the painful bits. Its somehow comforting to know that you also do trial and error every single step of the way - just like the rest of us. That being said: You could’ve just used ball bearings and a tube (I’ve seen good examples of people salvaging from the pedals of a bicycle for example) from most circular systems to keep the spinning rate fixed while not forcing the broach to over-spin instead of using Teflon which expands and sticks when exposed to heat and friction - then just made an Aluminium frame to account for the “force problem” which I think you overthought. I mean: clearly you have hydraulics in the shop so you’d be better off just using that. But if you wanted to use common folk tools, which it seems like you do, then fret not.
    Then for the barrel itself - housing it inside a tube that has the twist rate marked on the outside and then traced by tapping down a soft rod to make a helix-like guide rod around the outer cylinder thats housing the barrel - then have said outer guide rod fit through a notch at of the end of that Aluminium frame: controlling the twist rate whilst the ball bearings prevent over-spinning.

  • @peternewman6188
    @peternewman6188 3 ปีที่แล้ว +29

    For a quick force estimate:
    The ideal (frictionless) mechanical advantage of a screw is the input distance for 1 rotation (2*pi*r, where r is the distance of the force applied to the center of rotation) divided by the output distance of 1 rotation (the pitch of the screw). Assuming your hands are 5" from the center and the all-thread is 3/8" UNC with 16 threads per inch, MA = 2*pi*5" / (1/16") = 502.6. For every pound of input force with no friction involved, you apply 502.6 lbf axially.
    In reality, there is a large amount of friction associated with turning a screw (as I'm sure you're aware), and even well-lubricated screws have efficiencies ranging from 15-20% of the ideal case. Taking the low end of this means that an estimated real mechanical advantage would be something like 0.15 * 502.6 = 75.4. With ~60 lbf of input force, this means that the axial force you apply on the barrel is in the ballpark of 60 lbf * 75.4 = ~4,500 lbf.

    For whatever reason i thought you would just use the lathe with the tap. Looked a lot like when we're working on rusted cars (threads jacked up and everything breaking lol). Awesome work sir. 👍

    Ya know, you could have just drilled the top block without threads and just tightened a bolt down against it, pulling the thread up through a bolt, and no vice grips needed. Just a wrench.

      Seriously! That’s what I thought he was going to do!
      When he started tapping that block, I was practically yelling, “Why the hell are you doing that?”
      A nut is made to be turned. All-thread is not.

      Just a large washer, a nut, and a long wrench and plenty of cutting oil and he would have slowly pulled it right through.
      I truly do not understand his thinking sometimes.

    • @ryanmcgowan3061
      @ryanmcgowan3061 3 ปีที่แล้ว +4

      I don't know if the tensile strength of the rod would have still been enough to pull it through. It would have eliminated a major source of torsion, however if the nut at the bottom of broach still spun when it failed, torsion wasn't a factor. All the torsion would have been at the top of the rod between the vice grips and the block, but that's not where it failed. Even if it was drilled through, the rod has to rotate for it to matter. He most likely still needed a stronger rod.

      @@ryanmcgowan3061 a coupling nut welded on the end, and a tapped block on top about hand width high with 'arms' to slide a pipe over as a removable handle possibly would have worked. I know all-thread isn't the strongest stuff but I think it would hold up with that amount of thread engagement. I would have made jig with welded square tube & a bottle jack to push it.(with a bonus of then having a small press for future uses)

    FYI, kids: a 3-ft. steel tube slid over the end of the handle makes it much, much easier to turn.
