dirtydiesel Posted May 20, 2006 Share Posted May 20, 2006 Heres some thing an old guy showed me years ago, saves no end of time if you tapping out hard to get at holes, The nuts are just hammered on the taps. Apologies for carp photo. And you can even cheat and use the air impact gun (only recomended for cleaning damaged threads out though) Quote Link to comment Share on other sites More sharing options...
Mark Posted May 20, 2006 Share Posted May 20, 2006 What's wrong with finding the right size open ended spanner to fit on the square of the shank? I used this technique today on a 1/4" UNF tap I had - used a 6BA spanner. Nice Idea, but a bit 'animal'.... Mark Quote Link to comment Share on other sites More sharing options...
dirtydiesel Posted May 20, 2006 Author Share Posted May 20, 2006 Because my way you can use 7 feet of extension bars and a ratchet or a dumpy ratchet spanner, depending on what the access is like of course. I have found that it allows me to recover threads quickly and often "in situ" which helps. Me a bit 'animal' never Quote Link to comment Share on other sites More sharing options...

chaz Posted May 28, 2006 Share Posted May 28, 2006 This is a usefull technique and I've used it several times myself, but hammering a tap is never a good idea. Far better to use a vice and squeeze the nut on gently. I've got a couple of nuts with square holes filed in them for tapping awkward things....

Mo Murphy Posted May 31, 2006 Share Posted May 31, 2006 Good tip DirtyDiesel, I use a few like this myself at work (although officially outlawed !! ) but not with an airgun as getting the broken tap out is too much trouble I'll use the M6 with a makita battery gun for cross-threaded bosses but the others (8, 10, 12, and M14) I do with a rachet and socket. You can also buy a ratchet tap spanner, which is like a ratchet spanner but with different sized square holes to suit tap shanks. It's very useful in tight spaces. As Chaz says, putting the nut on in the vice is much better and don't forget to throw a rag over the tap in case it does shatter. I hope this doesn't sound grandmother/sucking eggs ...

matdiscobris Posted September 25, 2009 Share Posted September 25, 2009 Or alternatively if your not shy about spending a few quid the snapon man does a lovely set of sockets in 1/4, 3/8 and 1/2 drives respectively covering m5 to m20 taps. VERY nice but you have to have a great amount of will power to stop you using the rattle gun on them when your in a tiddle/hurry/sweat/tight space!!!!

Snap On also do a nice set of thread chasers, with hex heads. Also far better to use to clean/reclaim existing threads than cutting taps.

ejparrott Posted October 21, 2009 Share Posted October 21, 2009 I frequently use a socket on the end of taps at work for clean paint out of the holes on the winches, 9/10 its easier than using the tap wrench. Our hydraulics man has some Snap-on socket drive tap holders..apparently they were released in the states first, and he couldnt order a set! had to wait until they were released in the UK. Theres quite a few motor garages in Cov near his office, and the van calls in his place as well now... Quote Link to comment Share on other sites More sharing options...

simonr Posted October 23, 2009 Share Posted October 23, 2009 I use a socket with a lump of BlueTac inside to stop the tap dropping out the socket. Si Quote Link to comment Share on other sites More sharing options...
