      The Shadow kindly allowed me to show the scratchbuilding of a scale bolt!

      Step 1 is drilling a hole in a brass hex rod (In this case a 1/8" A/F rod). The rod is held in the 3 jaw chuck, & the drill in the drill chuck which is held in the tailstock. The thread I'm using will be a M 1.6, so the tapping diameter drill to use is a 1.32 mm. drill.

      Step 2 is tapping the hole made in the rod, in this case and as mentioned, I'm using a M 1.6 tap, which is also held in the drill chuck. This tapping is very carefully made rotating the 3 jaw chuck by hand, cause breaking a 1.6 tap is very easy and they don't come cheap!! Use also plenty of cutting fluid...

      [/IMG]

      Step 3 is making the thread on the male part. This is done chucking a brass bar of 1.6 mm. diameter, and
      tapping it with a 1.6 mm watchmakers die. We follow the same precautions as the above step.

      [/IMG]

      Step 4 shows the male thread being bolted to the hexagon bar using the drill chuck to center & hold it.

      [/IMG]

      Step 5 shows the Dremel Tools & Accessories 2 cutting the male thread to the needed length and finishing the bolt's end.

      [/IMG]

      Step 6 shows a 45º tool chamfering and giving the bolt's head its definite size

      [/IMG]

      Step 7 shows the parting tool in action...

      [/IMG]

      Step 8 shows the bolt inverted in the 3 jaw chuck being polished and chamfered in one sole operation...

      [/IMG]

      Finally, voilá the finished bolt...

      [/IMG]

      Thanks

    Bravo! Mario Bravo! Hope I can add a couple of tips here. Next time try wiping some Crisco shortning on the tap for a nice clean (burr free) thread cut. This also works when cutting threads for a bolt. The great thing about this is that it makes the taps last alot longer and it's cheap. The theory behind this one is that when tap or die starts to cut the threads, the shortning begins to melt at a very low temperture and lubes the tap plus the surface thats being cut. It doesn't take much, just a little dab will do it. Once you've completed your cuts, just rinse the parts with some alcohol Tools & Accessories 2 or soap and water. I hope this helps.

    OOPS! Sorry... I take it they don't carry the Crisco brand shortning where you live. This stuff is used for baking goods. It's like a form of lard. You just might find some in the kitchen.

    Hey, with the Crisco, after you get done making some bolts, you can make some cookies.

    Sheeeesh!!! Your skills make me want to reconsider model building as my hobby of choice and go open up a shoe store or something...

    It makes me want to get into the hobby room and figure out how I can do that without the lathe. Mario is one of my inspirations. If I can't do exactly what he does, I might find a technique I could use for something else. It's not a competition of who can do the best, it's about problem solving and getting around obstacles. Mario's lets me know what is possible. It's up to me to figure out how to do that. Thanks again Mario. Keep the tutorials coming.

    Harry, you'd just wind up having to re-design the shoes. There's no getting out of this stuff once you get started.
