For any future heat treating where you are unable to remove the outer surface afterwards, try using some high temperature paint meant for like 2000F, and paint the thing you are heat treating. This will protect the surface of the metal from becoming rough, and it will be harder as carbon will not seep out, called decarbonization. You could use a gas filled kiln, but that's expensive.
@@howardosborne8647 I find that borax is kind of annoying to get off, and it messes up the bricks and insulation in my foundry, so I don't really use it. I'll have to keep that in mind though.
A good idea when you need to urgently cut a thread, but according to the correct sharpening of a thread-cutting tool, the tap must have a backed part, otherwise it is a bolt with grooves))

Смысла выставлять фрезу нет никакого, здесь главное что бы передняя плоскость метчика была смещена на определенное растояние от оси метчика что бы получить передний угол 8-- 10 градусов. При даном способе фрезеровки нижний диаметр фрезы должен быть чуть ниже оси шпинделя ток. станка. Когда я работал в инструментальном цехе у нас была таблица в которой указывалось на сколько нужно смести фрезу от оси метчика при определенном диаметре метчика ,что бы получить заданый передний угол. В справочниках есть формула для расчета этого смещения. И обязательно на заборной части метчика нужно делать затыловку, а не только затачивать переднюю поверхность.
Sorry, but I would regard this as an emergency tap only, the sort you make and use when something needs to be got working and the correct tap is not available, and I have had to do this to enlarge a damaged1 1/4" BSP taper threaded hole to a sufficient extent to permit the 1 1/2" tap to start. As demonstrated, it works in thin metal, but if you have a deep hole to cut, it will take a large amount of force because there is no relief on the threads. I think I cut about 10 flutes and still had to use a lever about 2m long to turn the tap. Easier to take a high tensile bolt of the right size and use a grinding or cutting disc to make the flutes, if such is available. A real tap has its threads cut (or ground) at a number of settings off centre, to correspond with the number of flutes. Cutting the flutes in the right places then allows relief on the threads (like front clearance on a lathe tool).
It’s not really a tap. Its just a piece of steel threaded, machined, and heat treated to look like a tap. You could probably clean up damaged threads with it but it would not tap a hole in solid material.
@@ellieprice363 Yet you saw that he succesfully cut threads in mild steel with this homemade tap. I have a close friend who is a professional gunsmith and he makes taps from tools steel very often and they always cut a good thread.
@@samrodian919 Exactly👍. As i have just mentioned above my gunsmithing friend makes a lot of his own taps from oil hardening tool steel and they all cut very well. He has made a couple of Acme taps for me in the past and they both cut clean threads successfully.
One thing I couldn't tell, but did you slightly offset the endmill up/down so that it cut in relief? Or did you do that all post harden with the grinder? Either way, I'm going to steal your lathe milling technique. Lol. Nicely done.
Boa noite a todos, não querendo desmerecer o trabalho, trabalhei 15 anos numa fábrica japonesa de machos frescas e Cosinetes,,um macho não é simplesmente só isso.!!!!!
Excellent vid, thx! Which steel material (exact designation?) did you choise and why? Can you tell more about the hardening process? When it glows red just off into the oil? which oil?
Actually, I think that it's a better practice to do the size reduction of the shank as the last phase, so that you are working with the maximum rigidity of the part during the cutting of the thread and flutes... Or, so Joe Pi has taught me...
Threading is a lot easier when you have a reduced diameter section behind the thread. That way you have a bit of leeway when you stop the machine and reverse direction.
Nice job, but it looked like he took the sharp edge off of two of the three flutes with the hand grinder. It looked like the grinder touched the OD of the tap. I am sure it would work for a while, though, depending on what you are tapping.
@@Mastermind- Your welcome my friend ! Tell all the arm chair machinists to go buy there commercially made taps on a Saturday night at 7pm when EVERYTHING is CLOSED, and you NEED it SUNDAY MORNING !
I carefully hand grind the clearance when I sharpen the tap many times particular taping hard steel. He seems to be taping mild steel so can get away without grinding the clearance.
A very entertaining and interesting video to watch, in this case you have made the number 2 right? Because they come for games of 3, one of input, one intermediate and the one of output. I subscribe to your channel, keep it up, and I hope to see more videos like this. 😄😄😄
@@howardosborne8647 The style of tap used depends on the job. For through holes in very tough materials taper taps cut smoother with less torque. Bottom taps provide threads close to the bottom of holes that cannot go through the part. Medium taper plug taps are by far the most common and are used for the majority of threaded holes.

Muy bien echo maestro 👍,una pregunta que hacer es el que ocupo para fabricar el machuelo,deberia de hacer uno de de un dado tarraja,una humilde opinión para complementar la cuerda macho y la cuerda hembra.
I started watching this and thought you where nuts , but then I started thinking, let’s say you don’t have a metal lathe and milling machine and your in a pinch. Then take a grade 10 bolt and chuck it in a vise and with a couple of mini grinders just cut the flutes in the bolt and be done with it. I don’t know the difference in hardness between a grade 10 bolt and a HSS tap. But maybe for a mechanic in a pinch that needs a real long shank tap to chase treads down deep in a casting might do the job. I’m going to try this on a grade 10 bolt. Also those Allen head bolts are real hard to and they might work also.
amazing it's a high level skill
Thank you very much my friend
@@Mastermind- 11¹1
Q
It's only case hardened. What are you planning to thread ??
In my 51 years of machining background I had to make a tap only once. Very nice work and good and interesting video too.
That's awesome!
I am honored that you enjoyed the video
Thank you
I wouldnt bother
yes 51 years experience and 0 in video editing... the vid is fake. he pre cutted the tread ;)

Borax made into a paste also helps to keep oxidation to a minimum when torch heating for quench hardening

Amazing Skill,
Waiting nexs video
Thank you very much my friend
And, rotate the chuck counterclockwise, as you cut the flute deeper, to get more relief on one side, and more cutting angle on the other?
Excelente trabajo ,quedó como de fábrica

How did you put the clearance on the chamfer lead of the tap ? It won't cut unless you do.
I carefully hand grind the clearance when I sharpen the tap many times particular taping hard steel. He seems to be taping mild steel so can get away without grinding the clearance.

no my friend This tool is one number, and because I angled the top of it, there is no need for two or three tools
@@Mastermind- tilted very little, a smoother entry into the hole is needed.
The three styles of taps for a single thread are taper, plug, and bottom.
@@ellieprice363 Not always the case. Machine taps cut the thread to full profile in one pass with just the one tap.
