RE: Source and size of TF screws, bolts & Taps

[Bullwinkle <yd3@nvc.net>]

And at least two different drill sizes for the taps: 1/4 by 28
requires a # 3 drill (0.213) and the 8 by 1.00 mm requires a J
drill (0.277). If my chart is right, and I haven't transposed
numbers again, the 8 mm is quite a bit larger.

Thanks Lew for catching my switcheroo.

BTW the 8 by 1.00 on my chart says French (remember Hotchkiss?)
and the 8 by 1.25 mm (requires a 17/64 drill, 0.265) says D.I.N.
