I know awhile back guys were looking to re-tap threads inside the beds and die the threads on the nuts and would like the tap and die to do this.

Get on ebay and purchase them. The die is about $30-40 range.

Thanks Steven and Rich

I have a few of the tap and die for the 12-20 and thinking of selling some of them.

With the pair and never been used what is a good price to sell them for???

They are sold by Victor for around $25 plus shipping new, so figure from there up or down depending on manufacturer.  Tap     Die

I'm pretty sure it would require that the tap be a "bottoming" type. The holes are not very deep and they are cast iron.

Victor Machinery was able to locate and sell me a 12-20 bottoming tap a few years ago. Perhaps they can again.

Is this one a "bottoming" tap?  They sort of mention it but I'm no expert.

Yah all of them are bottoming taps and will come with the dies as well.

Bottoming taps are not tapered and have threads all the way to the bottom and the bottom is flat also. The one you had a link to is NOT a bottoming tap

,,,,,,,,,,,,,,,,,,,,,,,,
Arlin is correct...BUT I have made them into a bottoming tap by grinding the tapered end away..As it is, it would be just "fair" as a starting tap if you were very careful about aligning it to the hole to be threaded...Cast iron is not very 'forgiving" tho, so it has to be pretty accurately aligned...To thread a "blind" hole in C.I. you need to have a "feel" for when the bottom of the hole is reached and not continue forcing the tap or you will destroy the threads.

I have always been pretty convinced that Stanley used "unconventional" threads so as to become the "sole source" for parts...
