Cheap Reversible Threading Attachment?

[Boyan Silyavski]

Ok. Thanks.

Obviously number 1 solution would be on a big mill like that bellow, though i have to go to my friend Jeff to do that on his bridgeport



Next seems the BFE is too short for that attachments:



That all leaves me to use this:



or make from this/the one on right on first photo/ something like the tapping fixture on second photo and power it by my cordless driver and use its clutch against tapp breakage. that seems to be the fastest way to tap correctly, as i can speed the driver on exit just using the trigger and can change direction for a second

Boyan,

the tapping fixture you show, last one, is really handy for making good threaded holes. I have one and prefer it for small parts than the autoreverse tool
