Extraordinary detail ! Super helpful !! I learned lots !!! Thanks mate . 👊🏼 🔥

[@chriserickson4417]

Who would have ever known all this. I'm just now (late in life) learning all this, knowing how to put together pieces of metal through methods other than welding is a great tool in my toolbox for metal work. Now all I need is some practice and the necessity of it all will bring out all my inventions. Thanks for the video.

[@Thewatson77]

Great info. A lot of people don’t realize there are so many variations.

[@davidl9410]

Form taps are the only tap I use in stainless. Never had one break. Just make sure it is intended to be used in stainless

[@lordvrouxgames7332]

Wonderful content. Thank you

[@joels4208]

Great video... I have a new project requiring hand tapping into the sides of the casting of a milling machine. The holes will not be blind. Is there a particular tap that is best suited for tapping holes in cast iron?

[@rudydaberry122]

What’s a good tap set for cleaning buggered threads up in a mechanic shop? I’m just getting started in this industry and don’t really have much knowledge on taps.

[@rapidenterprises5681]

Nice

@7:40 something fell... I'm listening thru headphones and it sounds like it is directly behind me! Just spent 5 minutes trying to see if the cat pushed something off a shelf! (seriously)

"It even covers METRIC size's." (like most of the world has for many many many years). Should a student of yours, try to work abroad M/F, F/M or any other gender, it would be very difficult to find a position in a company working in Inches and Thou's ( known as the Banana scale).

[@iansandusky417]

Eh, I guess - but converting metric to imperial and vise versa isn’t exactly hard. I’m in Canada and my shop uses exclusively imperial measurements and the vast majority of my customers do as well - it doesn’t mean when a metric drawing or metric thread call-outs come in that we can’t figure it out 🤷🏼‍♂️

[@merouanebenderradji1582]

@@iansandusky417 that's true of course but trying to convert tolerances from metric to imperial or vise versa is tricky if you don't know what you are doing
