    Tapping with Torus Pro and Reversable Tapping Head

    Saw a lot of questions about tapping with the Torus Pro, so I produced some footage. Let me know if you have any questions. Made tapping so much easier in a production enviorment.

    Thanks for recording and posting so many videos! I got myself a tapping head as well, but I haven't got myself out to the garage to try it out yet. Once I do (assuming it works) I'll record a video. Do you mind if I post it in this thread as well?

    Kelvin,

    FYI - I made a simple mod to my mill and the tapping head. I fastened a piece of 1" x 1" aluminum up between the webs on the bottom of the head, a few inches behind the spindle. I put a 1/2" diameter vertical hole in the middle of it. I then removed the torque arm and its mounting plat from the tapping head, and made a new, longer plate, and attached a piece of 1/2" rod to it vertically. I can now insert the tapping head into the spindle, and the 1/2" rod extends up into the hole in the hole in the aluminum block, to secure the torque arm. I can now tap without having to hold onto the arm.

    I'll try to remember to take a few pictures next time I go out to the shop.

    Regards,
    Ray L.

    Great info guys. I've been contemplating a tapping head as opposed to the cost of $$ thread mills. Thanks for posting.

    I finally tried out my tapping head. It's pretty great!

    I recorded a lil' video of it in action and am currently uploading it...

    Nice! That is a lot of tapping for sure. I can see it was well worth it for you to find a nice solution. Have you tried using just coolant? We get away with it on the Torus.
    I use different types of taps though. Mine actually push the material out the bottom. Of course they are all through holes. Would not work too well in a blind hole.

    I had done one set of holes like this before recording this video and I let a bunch of them go with just my Fogbuster going. I'm assuming the Fogbuster didn't help at all except for pushing the some of the strings away. It honestly seemed to work fine but I didn't want to let it go for very long.

    I've found lubrication - i.e. oil not coolant - is a BIT help when tapping, especially on smaller sizes.

    I'm curious how deep you guys manage to go in 6061, and what thread % you're aiming for. In most cases, I use a 70% tap drill, but I think in the future I'm going to go to 60%, or perhaps even less, to make lifer easier for the tap. I find 3/4" depth works OK for 1/4", 1/2" for #6-#10. Any deeper, and I risk tap breakage.

    What seems to me the biggest limitation is the VERY abrupt reversal when the head is retracted, and the fact that there is no predictable, repeatable way to set the clutch, to limit torque on the tap. I'm surprised they don't use a more "gentle" clutch to engage the reverse gears.
