Hi
I have decided to try making my own Dremel precision router base where the Dremel's threaded collar screws into a piece of thick perspex (or
wood, depending on what I choose to use).
A bit of googling came up with suggestions that 3/4" 12TPI taps would closest suit the job. So I bought some, in particular these ones:
http://www.rdgtools.co.uk/cgi-bin/sh000001.pl?WD tpi&PN=bsf_TAPS_AND_DIES.html#a451
In the description it says "A FULL SET OF TAPS INC 1ST, SECOND AND PLUG (3 TAPS)"
Coudl someone tell me what it means by "1ST, SECOND AND PLUG"? Are they for different purposes, only all three look the same to me!
The other thing is - does anyone know what the ideal drill bit size, in mm, would be for these? I have had a look here:
http://en.wikipedia.org/wiki/List_of_drill_and_tap_sizes
But can't find a 3/4" 12TPI one, but then I am a complete novice to this so make have missed it.
Thanks Bigus
