Hello Chinggu! It’s amazing the grinding slop you can find in brand spanking new chucks!!!! Even in some mega buck chucks. Your really a super machine person! I don’t know how you can be sooooooooooo informed on so many aspects of shop knowledge???? The only thing I know about electrical is how to reverse the spindle on 3 phase system when it been hooked up wrong. Even when I do, I’m absolutely terrified I’m going to be electrocuted!!! Can’t wait for your next videos????
Oh, of course. I always throw mine away. It never occurred to me that it's a free spring I could use for something else. Like holding parallels in the vise.
The cardboard trick was surprising and useful. Your video content quality only improves. It must take forever to overdub the entire production. I hope all is well with you and you family.
Thanks Robert, glad you found that useful. Voiceover takes some time for sure, but keeps the video moving and keeps the viewers interested. I can't speak and do at the same time.😭
Great video, My own personal opinion regarding using grease, is simply…Don’t… It just acts like a magnet for dirt and metal chips, and as there are no fast moving parts or high temperatures there’s really no need… All I’ve ever used on drill and lathe chucks is a light coating of a light oil like 3 in one., and I’ve never had any problems or concerns…. After time grease becomes hard and can actually seize a chuck… I recently bought an unused Pratt Griptru chuck extremely cheaply as it was seized solid..I dismantled it to find the original grease had set like varnish…after a thorough clean and oil it now works like a dream… Using a light oil makes future maintenance so much easier
"Bob's your Uncle..." Depending on what state you're in, Bob MIGHT be your Auntie. And as far as cleaning your lathe/shop, that is what small free-loading minions are good for. Feed them cold, canned peas 3 times a day and they will be knocking over each other to get an upgrade to the food ration. :P
I purchased a 'affordable' 5C collet chuck with D1-8 mount backplate from eBay a few years ago. The brand was H&H, unknown. But it was not a zero set. And had extreme runout. That runout was worse the further from the chuck, so it had a conical error as well as simple concentricity. I ended up buying a Bison brand chuck and replaced the junk version. Lesson learned. There are few import (from PRC) that I've found to ever have good lathe chucks. Sloppy jaws, so bell mouthed contact brand new is an issue with 4 jaw independent chucks. 3 jaw chucks with extreme runout (25 thou, typical). But I've had good luck with 1 brand that has a symbol of Saturn (the planet) that seems to be pretty good. I have no idea of their company name as I can't read Mandarin. I learned to just buy Bison and never deal with runout issues. It's a good thing my chuck buying days are over, as the price is 3x what I paid in 2004 for the 12 inch 6 jaw Bison and backplate.
The problem with most of these importers is that because the products are, shall we say, inexpensive, they don’t inspect any of it. It comes from the factory, goes to their warehouse, and on to the customer. That doesn’t mean the product is bad, as more recent Chinese manufacture has gotten much better. But the very cheapest, no brand units, are at the very bottom of the quality stack. Precision Matthew’s, Grizzly, Shars and a couple others tend to be on the better side. But as a result of the pricing, small touches in the finishing usually isn’t done, as that costs more to do than you would think. Top chuck manufacturers recommend (and may even make) a high moly chuck grease. And yeah, don’t skimp on it.
Nice presentation. Everything you said was true. Could you comment on the main gear and pinion gears? Are they cast iron? You omitted this crucial information. I subscribed anyway.
Very nice video. Thanks for sharing all of the processes you went through. Very nice chuck. Are you happy with the chuck and the price paid for it? I like the card board cleaning, excellent. Thanks again. Take care, Ed.
Love the Bloopers ! ! ! So.... what's the ratio of finished material in the final product to raw material actually taken? And how much of that material on the cutting room floor is the bloopers? Perspiring minds need to know ! ! !
Thanks Bruce. This video was odd. It took 26 takes just for the intro which is a lot. It usually takes 3 or 4 takes. There are about 7 hours worth of raw footages for this 18 minute video. People that haven't made a video and complain have no idea the amount of work goes into providing these free videos.
@@woodscreekworkshop9939 I've done a couple of videos and they are far from "proper" quality. But it was enough to convince me that you folks that do the "maker videos" are woefully under appreciated. Such great training examples for so many things for those that want to learn this stuff. I used your videos on the Spindexer Flip to do my own slightly different version about a year ago. While I changed things slightly it was mostly your example that got me going and that I mostly copied. So thanks for that!
I noticed although cast iron is used, higher ends ones are steel. In fact, Bison offers "semi steel" for higher end models, also suppose to handle higher RPM, which doesn't come into play for my manual machines. Thanks!
I just received my Matthews 5C chuck on Monday . For the reasonable price and true set feature it’s a great deal. Enjoyed your video, it was really helpful filled with great ideas . Stoning the drive plate being one great idea. I note it has a ball oiler port , will you be using oil in yours ? And what type . I have decided to use the collet locating screw as my locating reference point to the spindle zero stamped mark . Thanks BB
Hey, great tip regarding cleaning precision ground flat stones. I've never seen that before. Certainly going to use it though. Yuchol, do you have any issues with TH-cam and copyright? I've noticed you use some non-elevator style music clips in your videos. I got one of my videos flagged because there was a Fleetwod Mac track playing on a P.A. at the venue where I was filming. Super annoying because YT said they would just mute the audio as a "solution". Cheers, Preso.
Thanks Mark. As far as the music goes, all mine are royalty-free. If you Google "TH-cam Audio Library", you can go to free audio library that TH-cam offers. There are thousands of songs which you can filter by genre, mood or artist. Hope this helps!
@@woodscreekworkshop9939 Thanks Yuchol. I already use the TH-cam audio library. It's pretty good for incidental "machining music". It seems that YT has become a lot tougher on copyright in recent years. It's probably a good thing they supply their own "safe" music clips. Regards, Mark
Hi Yuchol - Happy Eater weekend to you and family! I know you’re a great value shopper - What brand of Stones do you recommend or did you buy for this type of finish work on parts?
The holes between the mating surfaces need to be slightly countersunk and then deburred and only then use the PGS. If you just use the PGS, there is a very sharp edge that can form an upturned burr the next time a bolt goes through. I'm not impressed by the quality of their products. Sometimes it is better to get a used machine and restore it.
No, they don't need to be tight. But they have to go in far enough so the camlock actually pulls the chuck tight onto the lathe spindle. The notch on the stud exists solely for the screw to register on those stud so they don't unscrew.
Ocd but didn't clean with iso after he used a stone on a mating surface? You're not ocd buddy. Lol
I did. I just didn't show it because, well, how many times do you want to see a guy clean with alcohol in one video? I also took multiple bathroom breaks which I didn't show, but that happened buddy.

Customer service is everything. Many a business have failed in that aspect.
Unfortunately that's true, but there are few still out there.
Wow. I've never seen the cardboard trick to clean the stones. I already got my money out of this video, and I haven't even finished it yet.
I have few more tricks I'm holding on tight, waiting for the right moment.
The WD-40 on the cardboard is nice trick. I'm headed out to my shop right after this and clean mine!
Clean PFG's unite!
I absolutely love your attention to detail, and meticulous inspection and thorough cleaning/greasing of the new parts.
Take Care L.L.
Collet chucks, once you use one you never want to be without. Hope there is more content coming Yuchol.
Thanks my friend
Great Video, Yuchol !! Thank you for your work and humor!
Thanks Joe!
Nice Chuck. Looks nice. Can't do it with out those fine tools.
Thanks Randy. Your knocker and scribes were necessities as well.

Thanks for sharing.
Glad to hear it Joe.

Thanks Chuck.
Looks like a very nice unit. Have fun with it.
Already using it on projects. Thanks!
Made me laugh when you tossed out the chuck wrench spring.....mine went in the surplus spring bucket as well.....🤣
Thanks Eric. Those are impossible to actually use.
Oh, of course. I always throw mine away. It never occurred to me that it's a free spring I could use for something else. Like holding parallels in the vise.
I have the same chuck in D1-5 from Precision Mathew’s and am very pleased with it. I am able to dial it in to .0001” consistently. It’s a great value!

Thanks Harold. I think it will be more accurate than I can manage to machine.
Ive been wondering how to clean the dirt and oil off of my precision ground stones. Awesome tip!
Glad to help!

I triple dog dare you.
Man, that's some great accuracy! It's really hard to get better than that unless you have an infinite amount of time and money. Great video. 👍

Angry 🦫marks! The precision stones are a life changing item in the shop.
Yes. Once you see the light, it cannot be unseen.

Depending on how this one holds out, Bison would be the next option. Thanks.
Nicely done, now I have to go tune mine!
Good luck!
I never would have thought to disassemble and clean and stone. I would have just slapped it on the machine and wondered why it wasn't accurate.
There is joy in not knowing sometimes.

Traditionally a backing plate is made of cast iron for stability. I wonder if that method is still in use.
