I believe these videos are from when he worked at the school. He had access to more machinery but unless he dubs them, sound will not change. Remember this is not tv but a generous individual giving his time to post free videos to help educate anyone willing to listen. Keep that in mind for most RU-vid uploaded.
Thanks Francisco for understanding that I am just a retired toolmaker having fun while helping others. That is what RU-vid is all about. Thanks for watching and for taking the time to write, Marc
People complaining about audio quality need to grow up. Also, it sounds like they never have been instructed on a machine in a noisy shop. It is just like a real class experience.
My friend works in a machinist shop an he is going to hire me , I'm scared because my math skills are horrible , I'm good with my hands though an I catch on quick I just suck really bad at math .
Whatever you are mr Marc my gratitude for the time you dedicate to do the helpful videos my best wishes for you and be safe be healthy and enjoy your machinists
0:28 - Why is it expensive? 8:04 - Can you explain more why a table on top of another table (ways) makes a more accurate motion? You said it's due to large contact, does that mean it makes it more rigid?
Where oh where are these notes and project diagrams that you keep on referring to? I have repeatedly asked this question with no answer and I'm one of your dedicated listeners. Please, someone, tell me where to find these notes.
I am amazed at how much I did not know about what I did not know about cylindrical grinders. Thank you for the in depth overview. I will most certainly be looking for part 2.
I am disappointed that some viewers of this video don't appreciate the time and effort that goes into producing it. Yes, the audio would be better if a lapel mic were used, but I for one watched it to gain more knowledge. An appreciative viewer.
Thanks Richard, it's all for fun and for helping others, it's not about producing the best video or getting the most views. I am glad to see that you (and most viewers) know and appreciate that. That however doesn't mean that I do not try to produce better videos, I do what I can with what I have. Thanks for your support, your viewership and for taking the time to write. Your comment made my day! Marc
I ran a Cincinnati Millacon grinder back in the 70s and 80s. It had a 32 in wheel 3in wide. It would hold 110 in length by 36 in diameter cylinders. But the normal cylinders I ground were, body Dia 14 in Dia, the bearing journals were 3 in Dia and the gear journal would be 2 in. We had to hold 5 tenth tolerance, 1 tenth taper and 5 tenth runout. We made cylinders for printing newspapers and magazines
Thank you for sharing your knowledge. As long as you keep talking, I will be here, listening. This level of explination is the missing link for hobby machinists worldwide. Keep going,you're great! Can't believe it took this long to find you....Thanks again.
Excellent video and introduction to Cylindrical Grinding. I would be interested in a briefing on maintenance of these machines; daily, weekly etc. Also, fitting of grinding wheels; balancing would be critical?
Marc, really enjoy your presentations! I would love to have the ability to perform centerless grinding but have not the room nor the financial resources to purchase a machine beyond my surface grinder. Do you have any recommendations for a "poor-man's" centerless grinder using a surface grinder? Would love to be able to produce cylinder squares.
Thanks a lot Marc, for me the grinder was always almost a mystery but now i think that i could walk into one for grind some punches for our turret press
Deat Marc, thank you for your video, it's been very informative! I would like to ask - I have a few parts that callout a N4 surface finish after hard anodize type III and also require to be sized after coating to a tolerance of less than 0.0004". the parts are tubular, around 3 inch long, 2 inch diameter. parts are aluminum so - not hardened off course but Ive read that type III anodize can reach 60+ HRC. would cylincrical grinding be the solution for this drawing callout in your opinion? thank you again!
Hi all. I would like to do some cylindrical grinding on my lathe utilising a grinding attachment. Just wondering what are the affects of the mixture of grinding dust and coolant on my lathe? Thanks Jozef
mod the wheel guard to catch sparks. extending past the bed, straight into the tray below... cover the ways, vinyl sheet, stiff plastic, ali...drain everything to the tray... grab a 20L bucket or three plumb up a separate system with washing soda solution. bigger the bucket, better settling... dont use soluble oils. water. and washing soda. wash it down with WD40 or similar after. lots of it. doing it dry? it gets EVERYWHERE. dressing is the worst part. its worth the extra hour or two to make some dedicated guards and gutters.
Thanks Marc, excellent educational presentation. You are the shop teacher I never had. Trying to work my way through all the videos. I learn from you. Don't die!
Hi Mark, nice to see you again!! Sound is fine, yet I do miss the 3d effects... We want more, so please find some time for your scattered around the globe students. Athens, Greece.
There's too much echo due to recording in a concrete room where the sound bounces off the hard surface walls. Using a lapel mic will greatly reduce the objectionable echo. Dubbing in the dialogue would produce a superior result without having to attach sound absorbing panels to the walls or hanging sound curtains to moderate sound reflections which, unfortunately, greatly interferes with excellent, well scripted and delivered, content. Would you give top ratings to a Mozart Symphony performed in such conditions. No, you wouldn't!
@@jimbeaver3426 It depends! If you judge Mozart (in this case Information) and you know something about music, yes you would give top ratings. If you judge the performance of the particular orchestra (in this case the microphone setup) you would -obviously- not.
Hi Stanley, I have a feeling that what you are referring to is important but English is not my first language and I don"t quite understand your comment. With all the experience that you have, I think that it would be important to make another comment in order to detail and clarifie your first comment. These comments are public so you could help others to understand more or correct something that I said that could be false or poorly explained. Thanks for taking the time to watch and for taking the time to comment. Marc
@@THATLAZYMACHINIST Hi Marc when cylindrical grinding was told not to allow the job to past the grinding wheel That means all ways keep the wheel in contact with the part your grinding
Yes, yes, yes! (See my comment above.) By nature, machinists are perfectionists so it's doubly astounding that the audio is so ghastly. There was no lack of talent or facilities. Check out the credits at the end of the video.
