SNS 378: Custom Buffer Adaptor, Swivel Base Milling 

Glad to see some old school manual machining again!

What makes me amazed is how seasoned machinists just eyeball the moment they run the part through the bit... Takes time to build up such experience.

Tap the end of a piece of 5/8" studding to M10.

I've never been so invested in a machining series like this vice build lol. It has to be because Adam has no time constraints and is focusing on using all of his skills on something he wants to be perfect for him. I would totally love to see what personal project he does next.

Love seeing a smaller project and back to the manuel lathe

Gotta love these SNS's....a nice little project like this one are great. Love shop projects.

I could watch the lathe and milling work all day! Love watching the clean cuts.....

Great work, Adam! You are such an expert craftsman.

I’d love to see more videos where we could see your hand motions when running the lathe.

I really love how the hardtail vise is turning out. I don't know if you plan on painting it, but I think just a coating bluing or nitride coating would look the best. I'd hate to paint over that beautiful casting texture, it just looks mean and like it's meant to be used and belongs in a shop.

It is absurd how calm you are threading that fast. I was making diamonds with how tight my ass was watching this. You truly are an experienced machinist.

You missed a joke opportunity at “move the stud out of the way”. Thanks for the vid

Really nice work, Adam! Customers notice those little details. Seeing you fussing about the casting irregularities reminds me of Joe Pie whipping out those small files you mentioned ordering.

Thanks again, Adam. It works awesome.

Always look forward to SNS before dinner.

You make it look so easy Adam. Love Saturday night special.

Thanks Adam, always love this kind of machining ....

Have you ever thought of making interrupted studs like a battleship breech, slip the nut down, then turn 1/4 turn to tighten rather than having to screw all the way off/on? Might be a cool side project/experiment to see if you can make "quick attach" hold down implements Very cool...your boss cleanups are more "precision" than many shops precision work! Keep em coming!!!!

Loving how the project's coming along so far! Thanks for the videos.

That Orange vise looks incredible!

Thank you Adam, I always look forward to SNS.

Exactly what I needed to help me get over my cold, an Abom79 video :D

G'day Adam. Nice quick adapter, which turned out well. The base for the turn table has come out looking good. Keep up the videos, looking forward to the next one. 😊

Nice, clean and confident.

Great stuff, getting right down to the business of making chips.

Another Super Cool Video & really enjoy all of these that you post, Very well done..

Thanks for sharing, nice adapter, nice job.

Beautiful work! ⭐🙂👍

Great Video.....Thank You......

Neddle files and don’t forget the handle you can get that goes on all as it has an expanding rubber sleeve that is compressed by the handle being screwed down and pushing an inner piece of tube against the rubber hence making it Safer and more comfortable too

YesAdam.I want to see the machining of the interior of the main body.Thank you.

Hi Adam, I love all of your work and I never miss a video. I feel I must say though, that I was always taught not use a file without a file handle. Sorry about this little bit of health and safety. John

Those pads are probably made in Beijing, where "vaguely in the ballpark" is industry standard.

thanks for sharing

The rear uprights on my 2002 Chevy Venture are 10mmx1.5. Of course nobody had a chasing thread but I used whatever rot-gut tap the local auto parts store schlepped out to clean the old rusty threads. All good now.

Great video

What a terrific project - thanks so much for sharing your expertise with us!

Nice job adam 👍

Good stuff

Marking drops is some of the best advice ever. Unless you have individual (marked) bins for each type of material you work with you might as well be working with mystery-metal. I use number and letter stamps and stamp the material type on each end, Yeah its a hassle and take a few seconds but it sure beats broken or damaged tools and/or disappointing results. Thinner and smaller stuff just put a flag of tape on it and mark it with a sharpie.

love it

Number 2🎉🎉🎉🎉 great quick work❤

I'd like to see you do a review of your new lathe, Adam.

Adam You are the Best

Great job. Thank you 😊

just buy the arbor on line.

Adam - the fluidity of those early machining processes was pure poetry.

❤ Good setups. You would make a great machine shop instructor in high school Vocational education trade school.

I love watching "shop projects". I am not a fan of the CNC stuff.

I bought an adapter like that ten years ago for my B&D angle grinder. I got tired of looking for the right wheels and discs.

Surprised you didn’t chamfer the swivel base after milling them so nicely.

Adam, you do know the best way to cut a one of a kind thread, right? Unique up on it. Ba dum tiss😛

It might sound silly as a request but can you keep showing yourself selecting your tools because I really liked seeing the types of tools

*Summary* *Intro* - *0:00* The project is to make a simple adapter to convert a metric buffer thread to a standard buffer pad thread. - *0:47* The adapter will allow the use of common, easily obtained buffing pads. *Material and Design* - *1:51* Material for the adapter will be 1-inch stress-proof steel. - *2:04* The design is simple with threading on each end and wrench flats milled into the middle. *Machining: Turning the Threads* - *2:22* To ensure concentricity, the original coating on the stock material is removed with emery paper. - *3:34* The outer diameter is turned and faced. - *5:44* Threads are cut using a threading tool on the lathe. - *8:26* Threads are cut to a depth calculated for a 29.5 degrees compound slide angle. - *9:04* Test cuts are used to achieve the correct fit. - *13:02* Thread fit is fine-tuned after testing with a flange nut. - *14:01* Thread triangles are used to measure the pitch diameter of the threads. - *17:30* Threads are polished using emery paper. *Machining: Milling the Wrench Flats* - *18:35* The partially completed adapter is transferred to a milling machine and held in an indexing spacer. - *18:42* The center of the part is located with an edge finder. - *19:12* A 3/8" two-flute end mill is used to mill flats for a 5/8" wrench. *Section: Finishing Part One* - *19:19* Measure outside diameter (OD) of the adapter to calculate depth of milling cut. - *19:42* Touch off end mill and calculate cut to create 5/8" wrench flat. - *20:27* Machine first flat. - *20:57* Rotate part 180 degrees and machine the second flat. - *21:12* Test fit using a 5/8" wrench. - *21:36* Locate T-handle for the lathe's chuck key. - *21:43* Deburr part edges with a file. - *22:09* Note to self: purchase small jewelers files. - *22:51* Set part length dimensions - *23:11* Part off the adapter on the lathe. - *23:50* Mark leftover stock as stress-proof for future identification. - *24:27* Face off parted end of adapter on the lathe. - *25:05* Remove burrs from facing cut. - *25:50* Chamfer edges. - *26:17* Locate metric drill and tap set. - *26:46* Select 8.5 mm as the correct drill size for a 10x1.5 tap. - *27:26* Apply Anchor Lube thread lubricant to tap. - *27:32* Use spring-loaded center to start the tap hole. - *28:16* Complete tapping the part by hand. - *28:39* Test metric threads with matching screw. *Section: Project Wrap-Up* - *29:09* Review finished adapter design. - *29:16* Summarize tools and processes used to make the adapter. - *29:56* Demonstrate finished adapter assembly with metric threaded buffer and buffing pad. - *30:29* Acknowledge viewer interest in shop projects. *Bonus (Unrelated) Section: Preparing for Next Project* - *31:26* Set up a swivel plate using a face mill on a manual mill. - *31:59* Center swivel plate using DRO; mount to table using counterbored bolt in center. - *32:31* Clamp swivel base down for machining ears - *33:00* Establish contact point, level ear, and set zero in the X-axis. - *33:58* Cut 50,000 off in multiple passes, and check progress visually - *35:44* Rotate part. Machine more ears in a similar fashion with adjustments due to part shape and clamp placement. - *40:18* All four ears on the swivel base have been machined flat. - *40:38* The next step for the swivel base project is milling out the interior of the main vice body.

I learn something good today too.🎉🎉🎉🎉🎉

The pfferd files are great nice packing. But!!!! be easing on the filing . I think Tom Lipton spoke about them.

Adam, this should have been on the CNC, you could make a killing selling them!

I miss the SNS series. I thought it disappeared completely.

👍👍

Handy! 🤣🤣🤣

"Perfect enough" will make everyone happy, but can break the ASMR mood. "Perfect" will eventually put the customer and the machine shop out of business.

Nice little adapter. Why do machinists trust the mill DRO absolutely (3 trips around a 6-hole pattern), but they don't trust the lathe DRO? Almost every cut on the lathe out comes the measuring tools. I don't have a lathe DRO, well actually I do, I use 2 mag-back indicators - Dial Read Out

Why was the boss counterbored? the screw could sit on the top. A 45 degree approach cutter would have left a nicer blend where the flat meets the casting.

Is there a market for these adaptors? Seems like the perfect part for small scale mass-production (e.g. creating a CNC process for).

Hey man is that a rule of thumb calculation for the thread depth?

Can't believe you just used emery paper over the unprotected ways of that brand new lathe, turned out nice though.

I think that vice needs a Snapon extreme green paint job. Black handle and screw. Red is boring.

Do you use a carriage stop when you are cutting threads?

hey Adam, how do you like the Icon wrenches? and I also would like to say i really enjoy watching your videos

Would those pitch diameter measurement triangles be any easier to use if they were magnetized?

Adam - would be awesome to see some of the other projects you do in your shop. No way you're supporting the new shop doing odd jobs for viewers, nor is the hardtail vice bringing in any cash (aside from RU-vid revenue). What are you using all these fancy new machines for??

Are you going to gouge the contact surfaces between the base and the body?

So what exactly are you looking at when you use an edge finder. Is it just looking for the wobble to stop?

If you had chosen to machine the flats to suit a 1/2" wrench it wouldn't have left much metal between the flats and the 10mm thread of the arbor, would it?

I'm surprised the triangles don't have a little spring steel hand to put tension on the work...seems very awkward with the tubing

Those grinding marks are nasty looking

👍🏻👍🏻🇺🇸🇺🇸🇺🇸🇺🇸

I need to find a mil to lure with.

That buffer adapter can be bought off Amazon and at good hardware and tool supplies for $5 to $10. Even Makita has one. They offer the 5/8-11 SAE size in multiple different metric sizes, i.e. M10x1. 25, M10x1. 5, M14. They also offer them with a male thread on both sides. Plus when you buy a quality buffer it usually includes that adapter with the tool. So it really wouldn't be profitable for Adam to mass produce them on his CNC.

adom what marker/ Highlighter is that brand

21:40, AARGH, It"s fingernails on a chalkboard.... I know that three jaw Chuck is not on a LATHE, but it's just that you left the key in it 😮 😊

22.07 I have a little warning about some needle-files, as you mention, because once I poked my finger-nail using one of them, the round sharp one. Ow what a pain. One have to control them and not goof around, the triangular, and half-round tapered also pointy as well. You do not want to poke them into your hand or fingers, and certainly not through one of your finger-nails. The flat needle-file with a square end is of cource more or less safe, being a miniature version of a flat straight file. Also, they must at all times be fitted with a handle, with their very thin and pointy tangs.

Just a question? Why did you not use a champers bit on the edges to get rid of the casting flaw? Great job! This is why I subscribed not to watch a million dollar set and not be used. 73 dan

With the shop and location you have, you could make $$$ teaching a trade to young students.

Not critical still means within a thou....

what watch are you wearing?

what is the purpose of a thread release

please tell me what is the name of the thread measuring instrument? which is shown at 15 minutes 52 seconds

Great manual machining video as always. I tune out the CNC stuff but that's just me 😬

Adam, you could become a famous brain surgeon as well handling that thread measurement thingy.

I like this type of sns except the HF wrenches surprised me.

First!

Perhaps new Rite Hite T-slot bolts that always start straight can be the project for another video? I'd watch it!

When did you grind that KBC mill table, is there a video made? 🤔

Do you have/use thread pitch micrometers? I know you've said the triangles are your preference for measuring thread pitch diameter, but I was just curious.

Зачем он прослабил резьбу, объясните плиз?

Every time I see external threading like that I think he's going to crash 😮.

Not to be Picky Adam but wasn't the adapter body suppose to be 1" with a 3/4" threaded end?

If we only could agree with ONE measurement system...
