Metric table needs expansion. I would but I don't know how to do tables. mores izes can be found here: http://www.engineersedge.com/tap_drill_chart.htm If someone sends me a link to how to do tables I will be glad to expand it. --Jkoether 15:36, 7 December 2006 (UTC)

[edit] Help Identify a Huge, Tapped, Wooden Block

I was watching a woodworking show on PBS when I saw the host of the show pick up a large wooden block measuring a foot on a side - it may have been a whole cubic foot - and placing it into a vise, he drilled a 4 or 5 inch hole straight through it. He was talking all the time he was doing this, but being a little hard of hearing, I missed out on what he was saying. He then got out a very large tap to cut threads into the inner surface of the hole he drilled.

That done, he cut the block in half. And he might have done the same thing to another block, but without a tap, and using something else for reference. Then, when it was done, he put the two halves of the wooden block together, to make something (that for all practical purposes) was a big wooden nut. What made this unusual, was the number of times the threading revolved around hole. The helical cut was only once or twice around the block. The block (essentially a huge nut) would fit on a wooden bolt, and turn once or twice as it was rotated to the point of seating the head of the bolt. Since the wooden bolt had no head, it could continue all the way through the nut, simply by rotating it.

What is the name for that kind of a wooden block? It has a big hole running through its middle, about 4 or 5 inches wide if the block itself was a foot to a side.

I think the wooden block was intended for use as a mold in casting huge metal bolts at a uniform pitch, and at a constant angle, and having a continuous thread. Just pour the metal in, let it cool, and then undo the two halves of the block. If there are any straggling pieces of metal, just file or sand them off.

[edit] Shaft Sizes for Dies

Can someone also add a table for shaft diameters that should be used for specific dies to get optimum threads depths (like %75). I searched little but couldn't find that information.

Something like this:

|Die Size | Shaft Diameter |

———————————————————————————

| 0-80 | xx.yy' |

| 2-56 | zz.ww' |

| ...... | ...... |

| ...... | ...... |

| ...... | ...... |

Die Size | Shaft Diameter |

———————————————————————————

| M2 | cc.bb mm |

| M3 | aa.dd mm |

| ...... | ...... |

| ...... | ...... |

| ...... | ...... |

You're vague here - can you be more specific? I've never heard of an "optimum thread depth." Unless you are referring to the thread 'standard' that says your engaged thread depth should be 1.5 times the major diameter. - Toastydeath 15:12, 8 December 2006 (UTC)
