Best Place to get a G1/4 BSPP tap?

[IanY]

Home Depot or Sears hardware section. Make sure they hook you up with a tapping handle as well. Plus, you might as well also get a 6-32 tap for resizing the fan holes on Thermochills

Here is what you need.

1/4" BSP 18 TPI (19 TPI if they have) tap
11.8mm Drill Bit

This one is real cheap, but they have other brands (Snap On is best, if they have)
