Windy Hill Foundry Machinist Squares Part 3

[@randolphflores3975]

For a bunch of recycled brake rotors, those castings turned out flawless, hats off to Clarke.

[@windyhillfoundry5940]

Thanks, these squares are guaranteed for 50,000 miles😁

[@glennmoreland6457]

Brake discs are a good source of decent iron

[@nathanhershey7897]

Two of those are mine 😁 placed my order many months ago! I have used them several times already!!! Plenty accurate for the work I do 😅

[@glennstasse5698]

One thing I noticed is that the castings all seem well done. No voids, no defects that were apparent from here. Pretty nice for a guy in his barn.

[@rustycowll5735]

I liked the fact that he's recycling old, otherwise useless scrap rotors.

[@thecheekyweta742]

It's such a privilege to see a craftsman at work.

[@richardw.foxhall3392]

Adam, enjoy your efforts. At one time as a young man, I began working for Teledyne-Oster. Oster machine company (now defunct) made Oster pipe and bolt threading machines. When I started the "war finished" machines that were being used to make the parts for the last 8 inch Rapid casting they had were in sad shape. All of the machinists who ran them, each had their " special set ups" to make them cut straight. After speaking to the operators I found a bunch of loose or dirty, under oiled gibs, missing nuts/washers, worn out or missing wipers let all manner of stuff where it did not belong. After giving each machine the health and welfare checks and thorough cleaning they desperately needed, the parts were straight and true. The guys were grateful to me for saving them from the extra set up time they had to invest, before. Please, if you haven't already recently been through your "old worn out KT mill" give it some well deserved cleaning and adjusting. Is it properly affixed and bedded to the floor, level, ways clean, gibs tight with all the proper hardware, and finally where is your Foxtail brush for removing chips? The air is nice for driving chips dust and all manner of stuff into and on your way faces. But good choice on the vacuum. Please find the time to give all of your machines the T L C that they need, so the next video with KT mill, you won't have to shim it to "true" it up. Thanks Adam, for letting me rant, I am Subscribed and enjoy your content, look forward to more...

[@rogerandlyndabeall3840]

Hi As a physicist and not a machinist, I would check two of your squares together, this eliminates the error your gauge square may have and doubles the gap error, making it easier to measure.

[@johnsawyer2516]

Roger and Lynda Beall Yours comment is in my opinion the most sensible and practical one on here.

[@mfc4591]

Rarely will you find a machinist who cares as much as you do about the end product, whic says that you care about the customer who will own one. As always a good job done.

[@billtheunjust]

I watched this with my 5yr old daughter and we spent the time talking about what 90degree corners were and what square was. What forging is and lots more. As always thanks for your videos. Also for an upcoming project it could be neat to make a fixture that would hold your makers mark onto the press to make it easier when you have many of these to stamp.

[@TomTalley]

Thanks for the great video. Seeing you deck off your scraper surfaced fixture plate to get the product flat really impressed me. That was a class move...all for go, not much for show. Get the work right, whatever it takes. Valuable lesson. Thanks for taking the extra time to show this to us.

[@dewiz9596]

Doing any work around the house, I ask myself, “how would Adam do this?”

[@windyhillfoundry5940]

Awesome 3 part video Adam. I'm stress relieving another batch tonight👌

[@Abom79]

Glad you enjoyed Clarke! Great job on the squares, They machine nicely.

[@SweetTooth8989]

Great job Adam, they came out looking great. They're about as square as you could realistically get on a mill without spending 4-5 times as much time on them.

[@matthewperlman3356]

Really impressed with the finish you got using the end-mill, especially when you showed the contact pattern from a light stoning. I would have liked to see two of these squares back to back after the brown an sharp just for comparison.

[@fryreartechnology7611]

I think I’d have to polish or grind mine because they look so so so very good they need that even grind pattern. Those are some flawless casting. Nice short production run

[@gordoneckler4537]

Another beautiful machining job and those are really beautiful castings from Windy Hill Foundry.

[@robertgraham2926]

Wish I had seen videos like this when I was young, may have changed my career path. Barley had computers back then. Hopefully your inspiring the next generation.

[@easternwoods4378]

I like that you're now clamping on the machined surface and eliminating any bending by clamping on the web

[@truckguy6666]

my thoughts too. hate to be that armchair critic but I could see a heavy clamp on the web twisting or maybe bowing the square in such a manner to throw it 1 thou out of square.. Just a thought.

[@jacksak]

If it gives me so much pleasure seeing your finished products, I can't imagine the pleasure you get from having done all that.

[@cannon440]

I guess these are pieces of art. At least you admit they should be surface ground. Another nice video.

[@crazyed979]

39:27 THIS IS MY SQUARE......THERE ARE MANY LIKE IT BUT THIS ONE IS MINE!!!! LOL I couldnt resist great video

[@austinatkinson4639]

Always get excited for new abom videos

[@gusviera3905]

Nice job, Adam. Take care and watch out for those hurricanes. We got lucky here in St Augustine with the last one. More are coming. Be well.

[@aarongrabowski5620]

Good job as always Adam. You are getting another thumbs up.

[@jamesbarisitz4794]

Great results. Those precision stones are the icing on the cake. 👍

[@clydebalcom8252]

Absolutely nothing wrong with self critique. That is why you are chosen for these projects.

[@herbertsunday5913]

Very nice work and I am very impressed with the accuracy you got with your milling machine. Really I mean Wow!!

[@bcbloc02]

Less than .001" on milled surfaces I say you did as good as can be expected. It annoys me when people talk about how accurate CNC is but then never actually check the parts that come off the machine.

[@cojones8518]

Clarke might want to add a raised boss in the web of the square to mill down for the touch mark and maybe a serial number.

[@hilltopmachineworks2131]

Good idea.

[@wheresmyskin]

I was supposed to go to bed and new video dropped. Thanks Adam, now I have to stay up and watch this :D

[@ChuckRoss77]

I cut my teeth in a cast shop...this project just brings back my hate of cast iron. Although, you pretty much knock them parts out of the park! Great video per usual Adam...thanks.

[@timothyforney1164]

Those turned out really well. That endmill finish looked amazing. Guess you couldn't have squeezed that into the last video.

[@zexsrah5836]

Love good machining nice work Mr booth

[@ErikBongers]

Checking the flatness of a part by wiggling it on the surface plate and seeing where it hinges only works with equal distributed weight - that is, a block of equal height. A square has a lot more weight on one end, and thus it will hinge at that heavy end, rather than at the... Einstein point or whatever it's called.

[@CatNolara]

Bessel points And you're correct, that's what I was noticing too

[@ErikBongers]

Right. The Basil point.

[@sagetx]

@@ErikBongers Right the Brussel Sprout. Oh wait.. This isn't Reddit..... 😏

[@davesalzer3220]

.001” is dandy for straight off the mill in my book. Ain’t nothing like a good sharp carbide endmill.

[@bengtjohnsson6758]

Hi Adam. I work for many years ago at an machin factory. And the old machinists always says that all cast iron must lie about at least 2 years out in free space in winter/summer so all tension dissapears from the ithem. When cast iron is new, cast, it is hard an change form at the time. They says that cast iron should be matures. love yours uploads on this channel..always see them at saturday at 21.oo lokal time yous B Johnsson Denmark

[@chrisenright7003]

This is why BMW selected 'old' M10 engine blocks to use to make their turbocharged Formula One engines back in the day.

[@crisnevin7934]

The process is known as seasoning. It's a good piece of knowledge to have, but it really only works well in places with wide temprature swings for fairly long periods. You can accomplish the same thing using a deep freeze and oven, or by sending it off for cryogenic treatment, which gets it done much faster.

[@robwatkins4356]

Just love watching your work. You have been around machining machines for sometime. Every think about doing a series on buying used machines and what the hobby guys need to look out for? Keep the content rolling.

[@steveshoemaker6347]

You do the best....Thanks my friend...!

Tristan Hali well thankfully my work blocked KZbin so i will not get in trouble but yes i can see how that could be a problem at work.

[@davidmcduffie1398]

Nice job Adam, those squares turned out amazing and the makers touch was right on point !!!

[@tacitus101010]

One of these squares would make an amazing hand scraping project!

[@larrybarnes3920]

Beautifully cast and beautifully finished. I want one.

[@rodneywroten2994]

Beautiful work Adam

[@chrispriest5065]

WOW if I managed to be 1000th out I would personally consider that to be well close enough. Keeping in mind 1000th is a cigarette paper damn that would be well good enough for me. Well done Adam.

[@disklamer]

For ultimate precision keep a Rizla handy to shim up your work, great idea.

[@grahamstretch6863]

disklamer I used to have to scrounge a Rizzla paper from one of the guys at work, tear it in halves lengthways and put the pieces along the top of the fixed vice jaw to pack the jaw back to perpendicular to the table! Very handy item to have available. 👍

[@disklamer]

Tools for the ages, I'd buy one just because.

[@carloscordero4204]

Wow they came out nice!!! Thanks i really enjoyed watching this!! Thank you Adam!

[@uspatriot4261]

Love watching your videos Adam, keep them coming !

[@darkwinter6028]

Something to be aware of: the embossed maker’s mark will have left a raised edge around the logo. If it hasn’t been done yet; that area should be ground flat with a stone.

[@jonedmonds1681]

Enjoyed the content. To true these up could you use the x axis to finish both sides? Use a stop on y axis. Use the 2 pins in y and adjust the radius of one of the pins 1/2 thou or so with a stroke or 2 on the flat stone, clamp your best square against 2 pins on y, and run your 10ths indicator down x, repeat until it reads true.

[@TrPrecisionMachining]

very good video..thanks for your time

[@MikeHarris1984]

You sir.. are an artist with machining... I wish I had your skill! Great content and good teaching! I miss the colab with This Old Tony with his cut away of you giving him a look or talking shyt, lol.

[@yqwgjsg]

Hell, I’d just love one of these for wall art.

[@specforged5651]

I really like the color and/or patina on those castings. I would imagine it isn’t too much patina at this point, but I really like the shade. I would assume that has to do with the certain quantities and makeup of the raw casting material itself. Maybe it’s just the light, but they almost have a copper tint to them. Very cool and they look great! I’m going to buy one just to have even though I haven’t even purchased my mill and lathe yet.

[@thomasstone1363]

that copper colour you're seeing comes from the red Iron Oxide. Cast Iron is really lovely stuff

[@specforged5651]

Thomas Stone. I figured it was something like that, I’m just not super familiar with makeup of cast iron even though I use it all the time. I’m sure a lot of it can vary in color depending on the foundry. Thanks.

[@thomasstone1363]

@@specforged5651 Yeah I reckon casting temperature has a lot to do with the colouration of the oxide. My experience of the metal is hand filing and shaping it and I was surprised at how nice it was to work.

[@windyhillfoundry5940]

The color comes after stress releiving. It produces an oxide layer that darkens the cast surface. Straight out of the sand they are plain gray but after stress releiving the appearance is red. I wire brush that off to expose what you see here.

[@thomasstone1363]

@@windyhillfoundry5940 Thank you for the information

[@waynepollard6879]

Beautiful job ! Anyone would be proud to have that square .

[@mikegriffith8730]

Those hold downs with the built in brass jaws look a lot like old school rocker arms. A guy could make clamps by the dozen if any of the scrap heads still exist.

[@MySynthDungeon]

Nice Work! Cheers!! Enjoyed!!

[@josephcitizen4195]

You only need three points of contact on your fixture when doing the final ends 29:16. Great series anyway. Keep it up man.

Great work !

[@Steviegtr52]

I have 2 precision machine squares & they are both out. Maybe your cast ones are correct & the steel one is slightly out. Great job.

[@CatNolara]

I wonder, when hinging how much does the weight distribution affect the location of the pivot point? Because the part has more mass on one side than on the other through its triangular shape.

[@Nf6xNet]

Those are lovely!

[@Rubbernecker]

Great vid Adam!! Thanks for sharing!!

[@larryshedd5734]

Great job Mr Adam

[@rockwell6594]

Adam, thanks for all the great videos. Can I suggest that the problem of the out-of-squareness of the finished squares due to any out-of-squareness between the X and Y-axis travels of the milling machine could have been avoided if a fence had been set up truly at right angles to the to the X-direction of travel. Then the first edge of each square would be milled using your existing setup or similar, then that finished edge would be registered against the fence and the second edge milled using the X-axis travel. Obviously, that would have required resetting each piece a second time in order to mill the second edge, but it may have resulted in the finished pieces being more truly square. The resulting accuracy would then depend on how accurate the fence is set to the X-axis of travel and then how accurately the parts are registered with the fence rather than how square the X-axis travel of the machine is to the Y-axis travel. It would be best to set the fence with an accurate square. However, even an inaccurate one could be used if it is flipped over and the tramming checked both ways and any error is equalised. For the square flipping technique to work, the edges of the blade of the square would need to be accurately parallel, or alternatively, both edges of the fence would need to be parallel (and accessible) so that only the outside edges of the square need to be used.. Cheers

The clamps at 25:52 are from a company called All American (hence the AA mark on the castings) but they seem to be out of business now. Here's a catalog from a few years ago. Your clamps are on page 66.

we most certainly did not get to the moon using slide rules, we used the most sophisticated bleeding edge technology of the era, funded by blank checks from the government.

@@dolvaran yes. we also didn't use them to get to the moon. we used computers.

[@WilliamAdams5]

I've been watching a couple years now, and I have two observations. 1) I'm sure there are plenty of good machined goods from all over the world, but now when I "buy American", I know what to look for. 2) I have noticed that you use your hands as feelers quite a lot. Whether it's a fingernail test, or wiping a surface of dust, or feeling the backlash in a handle, your finger senses and muscle memory are probably super important to being a great machinist. That's something a completely automated machine may not have.

The worlds of engineering and machine work are all about specifications...the +/- numbers. Note this square: www.starrett.com/metrology/product-detail/20-3 ......0.0001-inch over six inches.
