Every type of video you make explains different things. Using a whiteboard helps to understand the steps. I like this electronic board because we can see an actual drawing and the way is presented; a mix of these techniques will improve our understanding. Thank you again. Not many people have the budget to pay for the time of somebody to explain this type of knowledge. I really appreciate these gifts to the Engineering community and myself.
The Fixed Fastener Formula provides the Position tolerance for both parts. You didn't finish the calculation T= .031/2 = 0.0155 for each part. Split 60/40, this would be 0.093 and 0.0062 or ~0.01 & 0.006. This formula does not account for the screw deviation due to straightness or the Position tolerance of thread to body. ASME Y14.5 has a note in the section warning users that the formula does not include these values. Screws from the various industry standards have different geometric tolerances and values, so they cannot easily include these in the text. People should be aware that this simplistic calculation is not complete.
That’s a subject I enjoy as well! I read a book called “Longitude” that was all about the development of the Chronometer for marine navigation. Thanks for tuning in to my channel.
Thanks a lot! That's very informative! Is there any chance you might demonstrate to replace two screws and holes assembly with two pins and holes assembly with clearance fits, say close running fit H8/f8? I'm searching for info on all kinds of fits applied to GD&T. Unfortunately, I couldn't find it. Thanks in advance.
Hi, thanks so much! I don’t have anything available directly from me, but I would recommend GD&T Basics: www.gdandtbasics.com/about-us/ I do teaching for them, although I couldn’t promise I would be teaching the class if you signed up.
@@RDeanOdell You might not have any idea how much people appreciate what you are doing. I wish you could be held in retainer as a consultant for particular questions. You are a good teacher. I can understand what you are saying even if the concept scapes me I am in the process of self teaching stack up tol from a book and the book is not clear about certain things it is a slow progress You are helping keep it up please
At 7:45 you said correctly that the Projected tolerance zonce was the maximum thickness of the mating part. But you are calculating the length of the hole for the part the screw goes through. Why is that?
A bit late but he does that cause the projected tolerance zone is defined on the threaded holes. You want to specify how far from the surface of the toleranced hole you wish to extend the tolerance zone, not how thick the tolerance zone on the toleranced hole is.
Hi, thanks for commenting. I’ll put it in my list of videos to make. I haven’t covered any datum targets in my videos, so it is something I will make a priority.
Hi, I do have a video about that in my CMM playlist. Let me know what kind of features you are looking to inspect and maybe I can make another video about it.

Thank you! I have no formal background in video content. I’m always trying something different to see what works. I appreciate the feedback!

Idk how Celestial Navigation brought me to Engineering but you're really easy to listen to haha

Great video! You’re an awesome teacher!
Thanks so much! Great to hear.

Awesome!
Can you share your source for the chart you use for your clearance hole tolerances? I would find that very useful.
Mr Odell, I love your work! Do you have a full course for gd&t? Happy to pay.

@@RDeanOdell Thanks mate. Really appreciate it.
Man! this is awesome..

You are a good teacher.
I can understand what you are saying
even if the concept scapes me
I am in the process of self teaching stack up tol from a book and the book is not clear about certain things
it is a slow progress
You are helping
keep it up please
Can you explain where did you get the tolerance dia .290 +.014/-.009? You mentioned from chart. I can't find a chart that has that tolerance.
Hello, is there anyway we could download this drawing for referencing GD&T?
Hi, send me an email (contact info on my website) and I can send over the PDF.

Hi dude, I need more details about datum target and movable datum target usages,
Kindly make videos of it

Hai sir please make a vedio on True position in MMC condition how to work with calypso
