        Agreed!  I feel this guy comes up with some very good ideas, usually well thought out.  I have a couple of spare T handle tap wrenches, I think I might just mill or grind the top of the shanks square, one already has a cross bar secured with a grub screw.

          Save yourself 17 minutes and look at the end where it shows the whole idea of replacing a perfectly good T-bar with a possibly wonky bar type tapwrench.

            Ignore Bazyle, he’s completely missed the point.

            The point being, 1) much shorter wrench for confined spaces. 2) allows a much larger range of taps to be held. 3) Square end can be turned with another wrench for greater leverage.

            renardiere7, I was thinking of the same modification to one of my wrenches. 😉

              Actually the main purpose was to provide a hole for the tap follower. A completely sensible thing to do IMHO. Personally I’m a bit of a brute, so I usually just power tap with a jacobs chuck. But it was a good build even without all the side projects, he tends to have very enjoyable videos.

                Good innovation. The square drive at the top is probably the best feature. 😎

                  Just a  thought, could take it further and make the square 3/8″ or 1/4″ and use extension bars from a socket set.

                    Or just use as is with a 12 face socket.

                    It would be interesting to do the CAD and see how many sizes it would need to be able to hold taps upto 3/8 or 10mm, I’m sure mine would have more than 3 different diameters. His all look to be one make of tap.

                    I also wonder why people make a point of mentioning using roughing mills on such shallow cuts, they are intended to break the chips when using a large amount of the side flute not the first 1mm or so, may as well have just gone straight in with his fly cutter.

                    As for the “only tap wrench you will ever need”, it only goes upto 3/8″ and even then he has to use a second larrger tap wrench to turn the larger sizes? I almost gave up 2mins in as he said he needed it to guide taps without a ctr hole. Why not just a female crt on the tap guide, many come with a reversible end just for that reason.

                      I think the one he showed was flat on the end – never seen one like that, but maybe they exist somewhere.

                        Well I won’t be wasting my time doing the CAD to see what sizes I would need to drill the end.

                        To be able to hold my most commonly use YG-1 spiral flute metric coarse taps in 2.5 to 10mm I would need 7 different size holes.

                        If I then add in the Dormer traditional sets of three and my ARC sets including M1.6 &M2 upto 10mm I would need an additional 5 holes

                        So not much chance of getting a single short holder, at the minimum I would likely need to make three with 4 sizes in each, might get away with a bit less allowing for it to close down on the larger sizes but there won’t be much movement at the bottom of the slot to close onto smaller increments. That is before I even look at metric Fine, BA, ME and assorted imperial sizes. One size does not fit all!

                          No problem with a near flat ended tap, there is usually at least a small chamfer (quite large on his) which will fit into a conical female c tr guide. I do it all the time.

                          flat

                            if you used socket set extensions wouldn’t you have to have a female sq for drive?. be better to have a hex head of say 10mm then use a socket

                              still trying to get my head around why hes junking perfectly useable tools to come up with something thats definitely not as durable considering the trouble manufacturers went to to harden everything for a long life IMHO.

                                Bernard, as I said if you used a socket with 12 internal faces they will drive a square as 4 divides into 12. Though with the downside of a smaller contact patch

                                As Someone said the best bit is the idea of the square end. But you could say that was to counter the failing of a one size fits all having too small a tommy bar.

                                If I actually used my only tee type wrench for larger taps than it will take then  it might beworth modifying mine to have a sq end but it rarely comes out of the draw anyway.
