Dill sizes for Lou's taps

[timben]

Im getting ready to do some kitless pens using Lou's taps.
What are the ideal drill sizes to use with then?
I searched the forums and Lou's website. Cant seem to find the info.
Any suggestions would be helpfull.
Looking forward to getting the dies.
Thanks,
Tim

Maybe this will help. I've not looked to see if the size needed is in this chart.

Since these are METRIC taps and dies, a rule of thumb is subtract the pitch (second number) from the thread diameter (first number). In these cases, the small drill should be 6.4 mm - 0.5 mm = 5.9 mm. I use a 6 mm with success. For the large tap, the drill bit should be 8.4 mm - 0.75 mm = 7.65 mm. I am using an 8 mm with success.

Soo now we have to use pickles to turn pens?!?!

YES! And kosher dills work best!

Thanks for the help guys,
I guess my spell check doesn't work on the title.

Hmmm... anyone tried stabilizing a cucumber?

On a serious note, I plan on getting some taps in the future, after I play with some and get a feel for it. I am looking forward to playing with Lou's taps in the future.
