I run a CNC lathe and a lot of parts that I make call for a 32 or 16 surface finish on 304 stainless. I can't tell you how many times that we've had problems with the surface finish, but I can't clean it up on the CNC lathe because of the tight tolerances and the lack of tool pressure. So, I give it to the manual lathe guy and he chucks it up and uses sandpaper to fix the surface finish. We've been able to save hundreds of parts over the years by using this method.

Words from a pseudo-professional (three years full time on a lathe): I routinely use coarser grits than 320; for removing nasty tool marks and quickly zapping off a thou, 120 grit -- and sometimes even 60, believe it or not. 240 and 400 are regular finishing grades, and 600 for super-pimpin' gloss.

The best tip I received concerning the use of abrasives (in the context of woodworking, but also applies to metalworking) is not to select a grade according to the finish you want to achieve, but to always think in terms of the finish you are starting with. Thus, an abrasive should be regarded as a tool to remove the imperfections introduced by the previous tool, and that determines the selection of the grade. In the case of sanding, you therefore start with a grit that is approximately twice as fine as your existing finish whatever that may be. This will removes the optimum amount of material at the scale of the existing imperfections as fast and efficiently as possible and results in a new finish as fine as that grit. If you want to go further, you simply repeat this principle - selecting a grit size to optimally remove the marks of the previous grit, and so on and so forth. The net result is the minimum amount of material loss for any given finish in the shortest possible time.

One thing to note about glass is that it's a lot more flexible than one might think, we can even see it bending just a bit in the video around 14:07 This probably isn't an actual problem (barring a very bumpy table), but local glaziers might have thicker glass than what is found in picture frames available cheaply and could be worth a visit. Or phone call, given current circumstances.

I've been using one for almost a year now and I love it. It's not too aggressive, and is long lasting unless you're deburring sharp edges perpendicular to wheel rotation (it will start shaving off the scotchbright; if you deburr parallel to wheel rotation first, it will leave a small groove in the wheel, but not eat the wheel as fast.) They are pricey.

One thing they teach in metalsmithing is you sand in different directions: 120 vertical, 220 horizontal (for example) and run the 220 until you can't see the 120 scratches, and only then move to the 400. That's the most efficient way. On a lathe, you could run X grit for a bit, then stop the lathe and briefly scrub it axially to see if it has removed all the previous grit's deepest scratches.

If you're trying to get a really shiny finish, using 2000 grit and above, it's best to rinse off the emery before you use it, especially if you store it in the same place as the rougher stuff. It only takes a few errant coarse grains to ruin the finish.

I used to use Emery cloth when I was a kid but when I got older I began using silicone carbide sheets in various grits from 36 grit all the way up to 5000 grit. It finishes materials better and it creates a more reliable /duplicatable finish. Also, for nice finishes on the lathe don't forget your long angle lathe files. They do a very nice job but it takes a little bit of skill and technique to master their use.

Great video and info! I’m glad you mentioned the “not to use it more than half of the width” and showed how to hold it but one thing to add to make it more graphical is NEVER roll the cloth around the piece you’re working on! MACHINE HAVE NO HEART!!!! That was my first and only accident I’ve ever had on the lathe, on my very first day of training (OJT)! My instructor was very experienced production (speed) machinist but not really an instructor. He just forgot the fact that anyone would be TEMPTED to roll the cloth under the palm of your hand and try to take as much material as possible in the least time to impress your instructor but, as anyone can predict by now, as soon as the end of that cloth catches under itself and closes the loop, automatically will pull in itself and your fingers in the process as any untrained/unharmed person will, also automatically, grab and hold that cloth to death to soon realize that there it goes your fingers under and between the cloth! And let me tell ya, one of the most excruciating pains I’ve ever experienced when my fingernail was smashed and pulled! I was lucky that I let it go fast enough to keep my fingernail and not break my finger, but the pain stayed overnight to engrave the idea of how valuable was the safety measures and how hard and heartless is any machine! Please, keep doing your little talks about safety as most of us have never done machine work and nowadays being so easy to acquire machinery to get started, what makes it super dangerous no matter how harmless any operation may seen! Thank you!

I have polished many hydraulic rick hammer buts with 400 grit off of a roll. No lathe, but I would hang it vertically. Start with a piece of it wrapped around a file to take off the high spots, listening to when they got smooth, then taking a long strip and wrapping it clear around 540 degrees (282 degrees celcius) so both ends were pointing the same direction and the paper was at an angle to the bit. Then pull and "push", working my way up and down. Once things were looking pretty good, get a new piece and wrap it the opposite direction to get a cross hatch. Then keep using the same worn, loaded piece both directions until I could hear it getting real smooth. Finally spray some WD on it and keep working it until I was bored and it was shiny. The used paper really works good for getting a shine because it's like using a higher grit. I do not recommend wrapping it all the way around on a lathe.

I used it as a coolant for drilling once. It works very well, but it also seemed to accelerate the formation of rust. Something to keep in mind if using it with carbon steel.

What about putting a piece of glass on the surface plate? I assume the glass is reasonably uniform in thickness, and the plate would keep it from flexing on the bench.

My favourite way to emery longer pieces is to clamp a band in the lathe's toolpost, start at the chuck, and just let a very fine feed rate send the emery down toward the tail.

I remember using this stuff in shop class a lot of years ago. I can't remember what grit it might have been, don't know if I even took notice back then, it was long narrow strips so I guess it was a roll of it around there someplace. I appreciate the suggestion of 320 grit as being a good place to start. On glass, no picture frames to steal any out of around here, but I *did* happen to scrap out a number of flatbed scanners a while back (all of them SCSI-interface so pretty much useless these days unless you wanted to add a SCSI card to your computer :-) and I *did* keep the glass, figuring that it might prove to be useful for something. You've just shown me what it's likely to be useful for...

my go-to sanding surface is a glass cutting board. About 8 mm thick (much more sturdy than picture frame glass), and it sits on rubber feet. I place this on a plastic serving tray, so I can use lots of water without making a mess. I sand a lot of plastic, and that really clogs up the sandpaper, so just wetting the sandpaper isn't enough.

With the emery cloth put the ends in the tool holder with a spacer(to clamp down)that way you dot have to hold it and you can apply a lot of pressure, it works a treat cheers from OZ.

You can also wrap long parts with the gritside of the emory papir against the part a few times and then clamp it down on the vise if it is a strange shaped part with only a few points of impact even with a strip of emory against the vice!

Ok so… short time follower, but these videos, ALL of your videos are “let’s make something, but wait teaching moment!” And I can’t thank you enough! Little backstory is I grew up as the son of a tool and die machinist who was a walking precision micrometer! I left for the Navy never to smell hot chips and cutting oil again! Well life is funny and has it’s ways (slight chuckle) and I found myself in a career where we often need to fabricate our own parts and yet everyone was scared of the “model shop” as we call it. With an ole Bridgeport and Monarch, long story short, I lost the opportunity to pick his brain about this stuff WAYs too early and you have been a source of knowledge and inspiration from then forward. I will be moving to the patreon side and look forward to maybe collaborating with you in the future! Thank you so much! -Jesse

Hi Quinn, great content once again. If I may interject briefly, as a former fabricator in a glass fabrication plant, i can assure you that glass is not flat. It comes in various degrees of "bowing" depending on the heat treatment, size, thickness etc. Most not heat treated glass is fairly flat but thin glass of that kind is extremely flexible and it will take the average shape of the work surface you put it on. Hope this helps

@mrsmith9079 Ай бұрын

Hello Quinn - have you heard of the process of fescalising? I saw a video of it somewhere on youtube and can't for the life of me remember where it is. It's where a ball bearing is pressed against a roughly machined piece and the ball flattens all the high spots. It gave a really nice finish on the example I saw.

@WimsMill 3 жыл бұрын

Nice summery. I often use the wet on the bottom of the paper between the glass and the paper. This makes the paper hold on to glass with surface tension.

Totally binging on your videos right now! 100% am a surface plate abuser. I figure by the time I need that much precision, I'll probably want a better plate and can just keep using the old one for lapping. Windex works great as a lubricant for this too - also used on diamond sharpening plates for knives and woodworking tools

Great video. Good info. You should also mention P grade paper. People use it interchangeably but that will get you in trouble. P320 grade is not the same as 320 it's coarser. I have a conversion chart that I downloaded to help with this confusion. Just search for P grade paper conversion chart. I also use a 12"x12" piece of granite tile from the big box store, for sanding. Works great!

Hi (Quin) Blondihacks Regarding Emery Paper you only need Grain 600. You make an Emery Paper eg a round bar came paper on this round bar you wrap paper around, you make 3 pieces with the same grain, you use the first one until it is worn, then you take the next one, you understand what happens. now you have 3 Emery Paper with different grains. the first is maybe grain 950 the next is maybe grain 800, you understand what happens then. You can also make these on a square rod. These I use for my jewelry, I have nothing but the 3 and one for wet polishing. These are some really good videos you make. Thumbs up all 10.

Emery paper is kinda ok to hold unusual or cast parts on the mill. I use a slip of cardboard that will squish. I also use cardboard to protect the vise jaws from rough sawn material.
