A lot of what I use my 770 for is small injection molds. These videos have given me some really good techniques for how to polish my molds. Doesn't seem to be a lot of information out there and getting this from a former mold maker is awesome. Love the bamboo skewer method.
Thank you so much for all of the kind words, Randy! Mold polishing, like mold making, has a lot of additional variables involved. The three most important bits of advice I can give you outright out be 1. Watch your tolerances and leave a bit of stock on your critical features, as polish does remove material. 2. Keep in mind how you want your material to flow when choosing a surface finish and 3. Mind the parting-line and shutoffs carefully. (It does not take much to roll a critical shutoff area.) Good luck and I sincerely hope that I was able to help you on your endeavors!! 😁
I have NEVER thought about polishing in terms of stress/strain and have massacred a Nambe bowl in the process of restoring it. Somewhere along the line I hit it too hard. I think it was with steel wool. I suspect that iron depositing on the surface kept it from forming an oxide layer, and to my understanding it's the oxide that we're trying to polish. Thank you so much, this was an extremely informative video.
Awww!!!! Thank you SO much, John, for the huge compliment! The best part of the job is knowing that craftsmanship is still valued and appreciated! I am sincerely grateful for you, taking the time to leave such kind words - it means a lot! 😃
I am ecstatic to hear that you have been enjoying it! I truly hope that you take a shot at doing some hand polishing - it is extremely rewarding to see something that you machined take on a whole new dimension. 😀
I thought about a tool for this. What if you got a sort of device like white out tape roller that has thin soft very anneled copper on spools that you unroll with a handle to lay down on a slope. Then you dip the tip in the polish you want, embed it, use it until its done and crank a small knob to advance clean copper against the 'anvil' so you can put different abrasive on it.
I am the type of person that believes that quality of material or workmanship is what grabs peoples attention. However, there are also those who notice the actual detail and effort that went into the job. I happen to be one of the latter and I enjoy seeing that extra effort and detail that very few will take the time to endure or make the effort to gain the needed wisdom to get the high quality results some have come to appreciate. When I do something, I want to do it once and just maintain as needed. If I spend 15 hours on a project that will look nice, why wouldn't I put in the extra 5 hours to make it look beautiful and exceptional. I enjoy admiring quality workmanship and even more when it's mine. haha Your video content is just that. Thank you for the information and demonstrating for us on how it's done the right way and why. Best vid I've seen yet on polishing aluminum
Fantastic tutorial, thanks! How does the polish hold up during use? Do you need to repolish every few months to regain the mirror finish, or does a simple wipe with a microfiber cloth restore the full luster?
That is a shiny light saber! That Jedi will have no problem beating the Sith as they get blinded by reflections, heh heh... But on a more serious note, good job on the topic! I was 110% oblivious as to what goes into polishing. Not only the process, but the science behind it. I would have sworn it was a matter of buffing imperfections away, but by your explanation it almost seems as if you are repositioning the metal groove by groove until it becomes "flattened"? If so, polishing is more of metal forming than cutting? I may have misunderstood the concepts, but either way it looks amazing!
That's amazing! I am about to begin pouring aluminum cast pistol & rifle casings just for the fun of it and wanted to know if aluminum could even be polished to a mirror finish. What would you recommend starting with since the diamond paste would probably be considered a finishing touch? I plan to polish all my pieces by hand. Should I just stick with the typical incremental grit sheets from 100 range thru 2-8k type emery paper? (forgive my terminology if i'm wrong, I dont know much about polishing)
Have u any experience on motorcycle aluminum heads and carters?I have been literally breaking my head over some and , after removing the thick factory paint (with paint stripper.. unfortunately blasting glass beads was not possible) and tried with some rotary tools, wheels and buffing soaps, I have ended up with a fair amount of scratches and a semi polished surface. I cannot get into the small gaps and cracks, fins and tiny holes in and on the irregular surfaces of the cases with any of my tools and I was wondering whether you had done some similar work. Could I send u a couple of photos of those parts? Get a few suggestions and tips perhaps?
All tool steel can be polished with the same techniques we demonstrated, though it will take longer depending on the hardness of the steel. P20 is tempered at a Rockwell C hardness of 37 to 28, and it's pretty forgiving compared to other steels. Thanks for the question!

Hi,
You are not a machinist, you are an artist. Very nice work.
John
Correction: I should have said you are not only a machinist but a well accomplished artist.
John

@@jennybannink823 You are most welcome. It is nice to see someone striving hard for perfection with an excellent result.
John
good to have this information from a real expert
Brilliant explanation with modeling clay!
I deply regrets for using rotary tools, it's left orange peel marks as you mentioned. Thanks for your advice and polishing technique.
Love this kind of content keep it comming! A rabbit hole I did even know of to go down now
I am ecstatic to hear that you have been enjoying it! I truly hope that you take a shot at doing some hand polishing - it is extremely rewarding to see something that you machined take on a whole new dimension. 😀
I ♥️♥️♥️ hearing the whys in addition to the how-tos! Thank you.
Also, she sounded a little too excited when she said “0.5 microns.”
Very interesting topic, I look forward to seeing more of the actual technique involved.

Thank you so much for the nice comment. Jenny put a lot of work into this and appreciates the feedback.
More... More. I wish I had seen this years ago. Bravo
More shiny. Learned a lot in this video as well as the first. Thanks!
Great content... I want to see more of this...well done Jenny.
Thanks, Enda! I truly appreciate the compliment and feedback! We strive to create content that really does help to inspire and create!! 😀
Thanks... I’d like to use this video for my machining classes..!
- cheers
Yes, you definitely can use this in your class! There are some resources in the description that you might want to use.
I would love this! The best part of what we do, is being able to share it with those who would like to learn! 😀
Amazing!
Thank you, so much!!! 😀
is there a way to predictably make the "orange peel" texture as a type of finish?
Fantastic tutorial, thanks! How does the polish hold up during use? Do you need to repolish every few months to regain the mirror finish, or does a simple wipe with a microfiber cloth restore the full luster?
Wow!

Why did you use the flat side to demonstrate the power tool merhod when they also come in all ranges of grits?
Will this work with nickel plating too?
Reminds me of spit-polishing my class-A (dress) shoes in basic! : )
I'm sure they were the best polished shoes in basic!

Hello, if you have to polish large chrome plated surface which is 62HRC how you will do this job?
Great video! This is like “ The Rest of the Story “ for Machining!
Do you ever use Cratex?
Does anybody have a link to the polish sje used
Love it
so cute.
Is that a lightsaber hilt?
Yes, this is the Lightsaber we helped The Hacksmith build last year. ua-cam.com/video/SC3jGEp5llU/v-deo.html
Wow
Have someone polished P20 steel molds?

Amazing video! I hope one day you could explain us how to use a tool called diamond burnishing, that tool can also polish in the lathe
Gesswein stones
Whats with her hair?
