tapping guide thingy

Mike K:
Nice.  Is the top bit spring loaded?

That`s nicely done Jimmy!  :thumbup:

I`m just idle. I tap the same way, with a small drill chuck, fitted with a 1/4" shank......

Nice Job  :clap:

You might have to be careful with smaller taps though...  You'll be able to put a lot of torque on using the handles.

Cheers, Arnold

bogstandard:
That is a very good point Arnold.

For my tapping attachment for the lathe, for small taps I use a knurled holder, but for my larger tap holder, up to 16mm, I have made the handle just 3" long from the centre point of the tool. This is so that if the thread is going to attempt to break the tap, I can't hold the tapholder handle any longer because of the short moment forces, and it is snatched out of my hand (safely may I add).
This is of course for power tapping, not hand tapping as this is. But handle length is critical for both, to prevent tap breakage because of lack of 'feel'.

Looks great, esp for larger stuff.

Do you just let the tap pull the quill down as you're tapping? For small taps that can be too strong a spring in it sometimes too. Suppose you could just lightly grip it in the chuck and let it slide in and out of the jaws. That's how I tap at the moment, just grip the tap with the wrench on the round shank and put the protruding bit in the drill chuck lightly nipped to allow it to slide up and down.
