Machining a 24 inch Straight Edge with 45 Degree Dovetail Episode 1
ฝัง
- เผยแพร่เมื่อ 26 ส.ค. 2024
- We begin the machining on the King-Way HKA-24 straight edge. This is the model that has the 45 degree angle on one side. I'll be using the shaper to machine this one and my plan is to machine all three sides with one setup.

Adam, those thin section ribs that gave you trouble cooled too quickly. The phenomenon is called chill. Chill results in "white" iron, whose carbon is in the form of very hard ferric carbide. Even though the chemical composition is uniform, cooling rate impacts hugely on the end result. The bulk of the casting that was machinable is "gray" iron, whose carbon is in the form of graphite flakes. White and gray refer to the appearance of a fracture.
Historically, "white" iron is regarded as unmachinable material that must be ground. CBN is harder than ferric carbide and might work, but that interrupted cut could easily damage very costly tooling.
Adam, all of the different camera angle views are great. Really adds to the video.
The shaper is so cool.
Abom79 - like you my Dad taught me machinery. We started in 1890. I noticed you always follow the basics. Always research the engineers who build the tools and never get greedy on a cut. Those are words I can still hear from my Dad. 44 years for me alone. Keep putting out great videos...I watch them all. Thank You!
Good day, Adam. I enjoyed the video, and then I decided to read the comments section. Will I ever learn? Sigh, probably not.
Please allow me to say that you have some subscribers who actually WANT to watch machining videos. Yes, even shaper videos. Yes, even LONG videos. Please don't let the people who are bad-mouthing your work get you down, you are at least doing something while they are sitting at a computer pretending to be superior.
A question: do you have an update on the K&T electric motor issue which is preventing rapid travel in the vertical axis? I forget if it was a sub-panel you needed to get 3-phase or something, memory fails me.
Hope you have a great night, I am off now to watch Part 2!
He did a whole thing on it a while back. Vids are in there.
Amen. The hate and shade are disgusting.. specially since the content is so great. Peace and love brother
the shaper working never fails to blow me away every time... slow methodical mind blowing levels of force
You really don't have to do "shaper work" off camera. That machine's motion combined with it's sound is truly mesmerizing.
I think it's the time it takes to edit it all, not to mention all the grouches would go off their heads about the video being too long, I agree with you though, watching the shaper is awesome.
I'm impressed by how flush the ribs were cast. Metallurgical casting is truly an art form.
Love watching the shaper work. I wish more people used them.
cucumber fruit I think they’re unique is all. Hobbyist, sure, but there’s a lot of finesse in Abom’s videos. A lot of what I watch on YT centers on hand artistry and obsolete manual methods. It’s fun to watch.
Looking at that casting it’s best chinesium. I’d send it back for remelting. Great perseverance. Bigger man than me.
@Jack Smith more like old cast iron engine blocks
Adam nice bit of chilled CI you have there very typical on thin sections the old timers at the iron works in the moulding shops would place pigs ( CI ingots front the casting plant ) very close to any wear surfaces in the finished casting to promote the chilling effect . This was at a time when the foundry’s only had very small windows to keep the sunlight out ( they pulled your leg and said the sunlight ruined the cast ) but in reality they judged the temp of the pour by eye so bright light upset the mark one eyeball .
As I machine parts for model loco’s thin CI is a pain in the butt as are blow holes at least you have none of those yet 😎
Cast anything can sometimes be a real challenge for sure. Hard spots and sand that needs to be gotten under can really tear up tooling in a hurry.
great video and editing. love all the different angles and seeing the feed mechanisms
Man the sound cutting the bottom was awesome!
Adam, as a long time viewer I had to comment that your weight has really dropped and you look to be in terrific shape. This is a poster for all the people who are struggling with weight loss, I know it not easy but you’d show it can be done! Hope for a prosperous New Year and looking forward to your videos on various projects.
Ah Saturday evening (at least in Germany)
Some could beers, and machining videos... Nice! 😎
Sehr gut!
Cold...
same in the uk
Martin L not quite evening yet here in Canada. 3:30 in the afternoon :)
@@brandonbenjamin9452 good enough!
Like we say her in Germany, "kurz vor vier, Zeit für'n Bier."
Like your videos also girlfriend got me a abom tee shirt for Christmas I'm a happy camper
The only problem with a growing subscriber count is the corresponding growth of dumbass comments and people trying to be smartasses and edgelords, keep doing what you do Adam, been watching for 4 years now.
I think I've fallen in love with that shaper. It's so elegant.
One of the things I like about shapers is that it is basically a massive beast of a machine that uses sheer brute force to do the most elegant cutting.
so awesome to see a true workmanship Adam. Love all your vids :) Happy New year to you and your family
The sand paper is smart. I couldn’t figure out why on the previous vidja. But I finally understand. :)
I love the RamCam.
Love watching the camera ride the shaper, very satisfying.
Man,
I know it's called a rough casting, but I think Richard King may want to improve QC.
Adam, what do you think about adding a little air-blow to attach to the end of the clapper box? A little low pressure thing like on some vertical bandsaws? You, know just to get the chips out of the way, no like a super high pressure coolant or anything?
Make bigger mess in shop, adding a vacuum would be a good compromise for small chips. They don't cause much trouble as the tool starts from the edge and pushes them away on the cutting stroke. On the return stroke they give the tool a bit more of a bumpy ride but not enough to matter.
Another great video, love watching the shaper work.
I love the shaper mounted camera views! Really get to see the tool and machine working up close.
Was this a reject casting?
I would have been if I had it.
So glad they have TH-cam in the hotel here in Germany😉Thanks for some beautiful shaper action mate too bad about the heat treat
Shaper is my favorite machine. Nice precision work. I'm starting school for cnc machining in a few weeks thanks to Adam, vintage machinery and others for sparking something in me. I can't wait to start cutting steel.
It looks like the tool is smearing the chips across the surface on the backstroke. Maybe you will achieve better surface finish by constant blowing the chips away...
Thank you for sharing Adam always enjoy your videos I am from South Africa
At the end with a new dressing the bit is in perfect harmony
Adam, Such a nice job on your King Way really enjoyed watching your video thanks for sharing hope your having a great day.!.!.!.
Happen that thin section of the casting cooled a bit quick...
That's why it went hard...
Pre-heating the sand moulds may help this...
And chucking in a bit of Ferrro-Silicon as well...🇬🇧☺️
Best camera work of the year! (Oh, yea nice machining too....)
60 Rockwell-- the low end of ball bearing hardness!
Damn Adam! You is looking trim my man!
(Oh and a happy new year to you and the family)
music to my ears! kinda sounds like the tardis from dr who lol
Been waitin on this since last saturday! I’m excited to see how you tackle the dove tail. I have a few ideas on how I’d do it but it’d be nice to see the “right” way to do it lol.
"How are you going make sure the bottom of the finishing tool is going to be square with the work?" I ask to myself. 24:00 Very clever!
If memory serves, you are going to Uncle Keith Ruckers for the Scraping Class...could probably throw that straight edge on his surface grinder to fix those sides up...
Adam, even though the "working" surfaces were machinable, please let Richard King know the problems you ran into when trying to machine the handle. He should know what happened and _may_ be able to have the foundry pouring his castings prevent that in the future.
Strap a brush for the tool and it will wipe chips off on every pass :D
MarsSheep Actually pretty smart. Clip/clamp on brush...
You beat me to it! Drill a hole in the handle and glue in some Harbor Freight magnets.
I bet you could mount a tool post grinder on the shaper and do it that way
You talked about the hardened casting issue in the video with the rush job housing. As I recall it is because the part was pulled from the mold too soon.
Hey Adam, just re-watched one of your older videos and man is that weight loss obvious! Great job! How much have you lost now?
I'd like to see a tour video of the casting process used in making the straight edges. Would be interesting. Of course never saw an A-bomb video that wasn't.
Windy Hill Foundry has cast some straight edges for Keith Rucker. Here is his site th-cam.com/channels/KHArSvqZlJrqB-F-AXOjgA.html
Thanks for the video Adam.
It’s very relaxing and enjoyable to watch the way you “getter done”. I’m sorry, didn’t mean to inject Mr. Fenners phrase in the conversation but it fits, “just sayin”.
JD in Missouri
ever think about trying carbide cutters, i have seen it done on metal planers, and i tried in on the 18" shaper i ran just by picking up the cutter on the return stroke, never got around to installing an air cylinder to do it automatic.
Nice and interesting as usual ;)! Greetings from Bulgaria!
Do you have a peanut the squirrel also? I see your hand is all scratched up :)
Maybe he is a secret shark? Violin makers used to use shark skin as the finest polishing grade after emery cloth - and he does take the honing of cutters quite seriously ;)
Hi Steve! (in case he is watching :)
HEADDYNAMICS Thats from me horsing around with Abby’s cats
@@Abom79 So when they scratch you they become Abby's cats.
@@Abom79 Welding Gloves are not just for welding. (Cat Catchers)😾😼🙀🙀. Also, do you still have your chair?
Only one Peanut the Squirrel. 😁
Would it help with surface finish on the scraper to have something vacuuming up the chips as you go? I wonder how much it's being scratched up pulling back over the old chips.
Where I live Westinghouse Machine Co. Used to be in business,any way when they closed down you could buy old machining equipment like lathes, mills, you name they had for pennies on the dollar.
Nice!! Great chips, sharp tool.... :-)
That interesting tool lift artefact on the side wall is visible at 29:29 again like on the first camel. You can see it developed/ing on both passes at 19:50 and if you look at the geometry of the tool lifter hinge it forces the tip of the cutting tool to the right and into the work when it is lifted up and it causes the light drag cut at the start of the return stroke until it rides high enough to slide freely. This effect occurs because the cutting tip is in front of the tool lift hinge/pivot. I used a office stapler to visualise the problem before I mentioned it again to make sure I was not imagining it. Someone who knows parametric CAD with animation could do a video clip of one stoke end with the geometry as set up.
It correlates with the previous video at th-cam.com/video/tU5uVNbduUE/w-d-xo.html
Use carbide fly cutter on mill?
Carbide insert on shaper?
Would this work?
No (in this case) carbide chips when its dragged on the backstroke of the shaper.
Does the collection of chips on the surface as the scrapper retracts affect the finish?
Great chips!
Shaper's the Lathe for flat stuff :)
nice to see that you having fun with your new machine :-P
I would not be surprised if the areas where the tool left different patterns are more difficult to scrape in. Guess we'll find out, eventually
That part may have been poured from the last in the crucible, end of shift on Friday ... or they were just not having a good day
Was that a ten thousands indicator last? Impressive - no scraping necessary. 😊
looked to me like the final variation was round 0.00003"
Absolutely as close to perfect as it gets. Ffs someone buy this man a beer! :)
My kind of ASMR...😊
What's the tool in the green Rototec case next to your roll-up door?
Afternoon Adam
Hope that the not heat relieved ribs do not come back to bite you Adam. Good luck too.
Victory First
I was thinking the same. I would have just abandoned the shaper to run it on the grinder. Do what you have todo to get a good result. It also looks nice and professional with the sides trued.
Ones side were true then strap her back into my favorite machine, the shaper.
@@louisturner8842 I totally agree with you Louis. One of my favorite machines is the shaper.
jeeze.. what'd they cast that thing in, a kids sandbox? that thing was rough..
Yeah, that's how iron castings are made, in sand.
I love watching you work, man. Makes me want to learn this stuff.
Been looking forward to the 45 degree one :)
Hi Adam. Could you use a brazed on carbide tool?
Have idea on how to build wiper so would be 100% adjustable for all tools/cutting. Light weight,easy change of wiper height/angle etc. Make from indicator base, arms, and clamps. Wiper itself could be artis paint brushes. Round handle to fit in clamps. Also be any widths. Also if oil used brushes would distribute oil evenly.if no oil just use new brush bushes are cheap.

They should have annealed the thing B-4 sending it to you. My opinion. They knew you'd be cuttin' on it.
You can't anneal cast iron afaik. If there are spots of hard white iron it happened during casting. Heat treatment is all about stress relief to stabilise it.
That's what I'd do. You do what you want. Sounds like the hard portions just cooled too fast.
@@MattOGormanSmith I was involved with some extensive rebuilding of some rather large castings from a big press that were cracked. The castings were pre heated to 600F degrees then we welded them out and immediately shoved them in a furnace at 1750F. This process was tested out on a smaller piece of the same material and was tested both mechanically and microscopically. It was shown this method stress relieved and converted the brittle zones from welding and made a good part as suiteable for service as it ever was.
@@MattOGormanSmith I annealed a cast iron pressure plate from a clutch assembly. There were hard spots from where the clutch had burned it (band saw couldn't cut it, carbide scraper wouldn't scrape it). I annealed it and the bandsaw sliced right through it and it was easy to scrape. From what I remember you need to cool the casting slowly to have it be soft. I'd guess that's why the ribs are hard and the thicker bottom side is softer - it would have cooled slower.
bcbloc02 cast is a bastard to weld I’ve done some but preheat was 400C and oven cooled over 24 hrs in stages
Thanks Adam
That cast was warped like a dogtail......not good at all
@@TheAggromonster you have to be american to be so patriotic, that a bad piece of casting from an area near you embaresses you
I have to say, the inability to machine the ribs is buggin' me.
Please allow a question from a non-machinist. Does your shaper leave a better surface than a surface grinder? I've heard that Jo-blocks have a super-duper finish to support their accuracy. Are these cut on a shaper or ground on a grinder? Thanks for the interesting videos.
I have to ask if there was any noticeable surface difference between the shear tool cut surfaces on the two projects, with the wider and narrower shear tool? With the wider tool, you get a second pass over much of the already cut area, which I would surmise might serve to burnish the surface a little more, especially if there is any fuzz as the tool wears and the cut progresses. Did you see any evidence of this? Of course, being cuts on two separate pieces of material might obscure this, as well.
I was blowing at my screen to get rid of the chips ;P
Lego Man 12345 12345 I tried that too. Didn’t work for me.
Adam, why can't there be a wiper brush mounted, on the clapper box, on the side so does nt affect the movement of the back stroke or cutting stroke. Also the wiper could be ahead of bit so wipes first then a secound behind bit, so wipes chips on both strokes. Bit would be on a clean sirface at all times. The assembly of wiper could be a cheap brush and base would b3 mag so remove easly to make tool changes etc.
Right off the top , I am not a machinist , my dad and grandfather were tho , but they have both passed away so I cant ask them. I have watched so many of these videos where parts are setup in the shaper and my question is: why not use a milling machine and mill it off ? Is there an advantage to the shaper ? Love watching you do your work Adam. Thank you !!
Easy.. Because it's fun. I mean... watch it, doesn't it make you smile? Once she's going it's kinda like staring at a fire with the guys.
The shaper up until the 1960s was the only way to do milling operations. Its fun for some people nowadays to restore and play with. It is still the best way to cut internal key seats for a key way
Thanks Jason ! That makes perfect sense. I never thought about the old school approach that people enjoy so much.
@@moefugger There's an old saying. You can make anything on a shaper, except money 😃
That made me laugh , that's a good one !
2:48 what is that thumper made of? Looks like lead?
Hi Adam, Happy New Year to you and Abby, hope you have great new year. Super mesmerising video as usual, Just as i was wondering about mag mounting the camera on the slider, you go and do it. Brilliant. Thanks for sharing, Stay safe and keep up the good work. 👍🖖
My kind of 'metal' music!
Agreed!
Question could you have cut the sides in with a fly cutter or end mill on the mill, and possibly cut like .002 off with the sharper afterwards?
Are you going to do a video on scraping those? I'd be interested in your process, a lot of people have slight variations that make a huge difference in the end product. :)
Curly chips in CI is unusual
Shaper, yipeeeeeeee!🤪
So if you wanted to cut the ends so all sides be in same plane. Could you turn clamp table 90.o cut each end so all flates are samp plane. Then retun tabl back to cut 45.o and remount work.
Looks like a trip to Lance's shop is in the future?
Mount your tool post grinder to the head.
Hello
Looks good. Would it help to put an blower on it to blow off the shavings? Idk I'm not a machinist. But you could hang the line from the ceiling so it can swing with the machine. Keep it up brother.
Great video this week. Hands look great. Must still be using that Josie Maran hand lotion, right AVON79?
Who's that?
Snorri Ö.K.
There was a funny sketch way way back, tried to link it but couldn’t easily find it and this video has just finished, moving on!
It was a This Old Tony video. I will find it and link it here soon.
Oh hey nice
Hi Adam good stuff as always.... Can you not put together a grinder to fit
On your shaper.....
Interesting that both of them have “HKA” cast into them. 😏
William Squires Richard usually grinds the A off the “Hk” models. Says it has to do with cost of casting.
Its a common thing to have standard info cast in and then grind out the bit that isn't relevant to that particular version afterwards.
Adam, ever think about starting a new channel? You can call it Machinists ASMR... call me and we can talk about my finders fee 🤣
What will be the cost of one of these ?
Say, would you think using a broad finishing tool as you did here would also work on ordinary steel?
Looks like a real timesaver over a shearing bit!
