I Had To Make a HUGE 40mm Thread Tap - Its BIG

[@alanmartinez45]

A good thing to remember when making the relief cuts. from personal experience using acme taps they always wear out on top of the trailing metal behind the cutting surface, after a few uses it ends up super polished and that seems to make the tap take a lot less torque to move, so for your application it might be worth to polish the taps then sharpen it, you will get a better finish!

[@francobuzzetti9424]

i swear. every time i see a machinist pull up the machinery's handbook i know sh*t just got real

Great to see the hacksaw making yet another appearance. Your cuts are a lot straighter than mine. Man! What a project, especially as it’s a project to make a project. Looking forward to seeing that project! Thanks for all your work. Les in UK 🇬🇧

Making a set of huge (for the size of your machines), square thread taps, by helical milling, from hot rolled mild steel, then case hardening seems ridiculously ambitious on the face of it. I'm amazed that you have pulled it off. Seriously well done. What is your favourite brand of hacksaw blade?

[@dirkv.9013]

Same here - MacGyver would be proud. For most of the video, I just kept watching because I wanted to see if the next thing would work. You can increase the carbon content of steel by baking it with charcoal? Wow. A+ for raw cleverness

Outstanding work. Your problem solving approach is intelligent, and skillful, and your execution is fearless. You just dive right in. Respect. Side note, your videos are also fan-friggin-tastic.

For the cutting of the tread, take 2 fix wrenches to get More power and dont get the power from only one side like on the adjustable wrench. For example two 36 wrenches. Great content!!!

[@michaelsimpson9779]

[@themasterisback1]

Hey there nice vid! A tip from a machinist and engineer: the relief angel you need to improve the tap more is on the taper of the tap. It's hard to explain in a comment but the cutting tooth have no clearance angle right now, because the outer shape was formed on a lathe. You can easily do this on the grinder by hand on the tapered part of the taps. I highly recommend the video from thisoldtony on this topic. Anyhow keep up the good work and have a nice day 🤘🏻

[@artisanmakes]

I mentioned in the end that I have the intention of doing that but my new set of grinding wheels hasn’t turned up yet

[@DanPetrePhotos]

You made it clear you were waiting for wheels and it will be more difficult to grind into hardened steel. I guess from a project management point of view you get the job done faster by shifting work before the wheels arrive at a small cost of having the grinding a bit more difficult. How long did it take to grind relief?

[@artisanmakes]

It’s usually a fairly quick job but I have yet to get around to it

[@jamesdrake2378]

I was thinking that guy with your skills cuts the material with a ordinary hacksaw. Respect on that.

[@patrickbeck4062]

I would just make the drive end 6 sided, so you can use a proper socket and whatever wrench you want. Most times when I and others I've worked with, use larger taps you end up finding the closest socket and using a 3/4 drive rachet anyway, because tap handles that size are too awkward and bulky to be able to use where you need them on a lot of machines (need too much space to spin the handle). Plus if you do it before cutting the threads it will give the chuck flats to hold onto. You could make 6 sides work with a normal tap handle as well if you change the angle in the holding inserts from 90 degrees to 120 degrees.

[@WompWompWoooomp]

Looking forward to that tap wrench video!

[@xerxespamplemousse6622]

this is why my brother has several editions of "Machinery's Handbook" going back to the first edition. The information comes and goes, and sometimes the old ways are best.

[@douglasharley2440]

sweet!...can't wait to see what you need those taps for. 🤣🤔

[@HoY_82]

Blacksmiths use an adjustable wrench with a bar welded onto the head for twisting steel, something as simple as that could work as a bigger tap wrench unless you have plans to make one of those too

[@nineoclockhero]

If you weld a bar to the fixed jaw of the adjustables, makes a quick simple tap wrench. Not very fancy, but I'm assuming you're not going to be 40mm tapping for a living. 😄

[@robgraybeal8089]

Interesting. I liked the video, but I would have purchased a TR40 tap from Aceteel instead of trying to make one though. They cost about $350 US dollars, but that is cheaper than I could make one. I have designed large automated equipment that used large linear drive screws and never had a problem finding large taps or screws. It will be very interesting to find out what this project is. Great video and I truly enjoyed it!

[@betaich]

Prices for stuff like that vary widely depending on where you are in the world. Where I am I would pay as much as you pay for the big one for a way smaller one.

[@Stefan_Van_pellicom]

22:35 You can have a square holed spanner lasercut out of 10mm steel sheet, or weld up something from 2 pieces of 10x40 flat bar.

[@axa.axa.]

hitting it with the wire wheel after hardening seems counter productive

[@stevensmart8868]

Nice work. I used to tap some inch and a quarter BSW threads through 30mm mild steel plate, for die sets for sheet metal. Anyhow we used a tap wrench that was about 3 feet long and even then it was hard work. And this is 40mm and square. Good job and good luck.

i think what you could try when forming the flutes and therefore the cutting edge is grinding them with a dremel and small ball grinder in the lathe with only the crosslide. You should get a pretty prestine finish that way.

[@battleaxefabandmachine]

[@OhHeyTrevorFlowers]

Next project: a big ol’ tap wrench

[@bluefalconcatering]

Great video 😊

[@Beef4Dinner22]

You mentioned that the helical cutting was using the bottom of the endmill and that was increasing the cutting force. Couldn't you offset the Y axis half the cutter diameter so that the leading edge of the end mill was at the centerline of the part? This would end up with a slightly rounded bottom of the grooves you are cutting, but it would mean the cutting was all done by the sides of the end mill instead of the sides and bottom.

[@switch2472]

It would be trivial to order a proper tapered end mill for the job. 25-55$ for a new one within the first five hits on Google-and you get a standard metric trapezoidal thread when you're done. Most large taps like this will be made as duplex taps-a V-thread tap preceeding the square/acme/trapezoidal thread-and it would be entirely appropriate to mill off the left or right side every other tooth or every third tooth depending on the number of flutes on the tap, and alternate the missing side of the tooth on alternating flutes. This further reduces the cutting forces. So-make a V-thread tap, then relieve your tap alternating left-flank/right flank/full tooth profile.

[@nate6386]

Next project comically sized tap wrench!

[@tcurdt]

The hardening process was particularly interesting. Thanks!

[@MathMikeAllen]

Hey bud, great content! If you have an adjustable wrench you are willing to sacrifice, a cheap/ excellent alternative to a large tap wrench, is to weld a bar to the adjustable jaw, equal to the length of the handle of the wrench. I carried one with me for field repairs and it did the trick for years. You may be experiencing high side loading on the tap without support on both sides of the centerline of the tap. Hope this helps!

[@smorris12]

I don't know if the terminology has become blurred or they've died out (my books and tools are all ancient), but "slot mills" are the thing for cutting those threads. They have two flutes and an offset centre divot to allow cutting on both edges. Also, they do tailstocks for use with rotary tables (although perhaps your mill bed isn't long enough) which would have helped.

[@ObservationofLimits]

He should have had his Y axis inwards so the outside edge of his bit was aligned with the center of the rod, rather than center on center.

[@jmyyer]

Impressed !

[@mootan2]

nice work

[@strawbs556]

Not to be a bother, but if you're going to use these in steel, it would be much better to have the 5 tap set done. At my work we use a lot of M48 size taps and a Machine is either used to do it, or a meter long tap wrench. That should tell about the force you'll be fighting when getting this done. Anyway, all the best to you. Have a good day.

[@thomaslindroos1667]

Adjustable wrench, weld a piece of roundvar opposite to the handle. And then maybe weld the wrench so it wont loosen up on you. Or spend 16 hours making a gigantic tap wrench

Great vid as always. please tell me you made these taps for some part for a bandsaw your making to get away from the hack saw?

[@hillonwheels8838]

Not sure if this would work since I have never done the work you are doing but could you have used a 4mm ball end mill to make the initial cut for the threads then fallow up the final pass with a regular 4mm end mill? You said that the tool puts a lot of end pressure on the bits and it looks like the ball end bits look to be able to handle that load. Love your content and you make it look so easy that I want to get these tools to start making my own stuff instead of having others do it for me.
