    We're moving onto the next machining op for the Fairbanks Power Hammer Cross head. In this episode we'll get set up in the DoAll mill to drill and bore the bolts for the two linkage arms. I'll share some info on the small boring head that was my Dad's. Also I'll be machining a custom sized washer needed for this project and do a simple heat treat on it.

      Hey buddy I'm new to your channel and I appreciate how you explain everything that you are doing. So far I've been impressed with the precision of your work. Thanks for sharing this with me.

    2. Marcos Mota

      If the angle plate is the squaring surface against the central bore, why not use the center of *that* bore as the tabbed base's? Meaning, pick one absolute for the whole piece and use that as the reference? The bore seems like the most important element of the piece. Also, bushings absorb flexing forces and keep the CI from cracking.

    3. Caliberxx

      Why no lubricant or cooling on these drilling ops? Just a wanna be machinist wondering...

    4. Allan Sutton

      How is it possible for a drill to cut oversized? It’s a defined diameter. Please educate me!

      1. Uncle Duncan's Shack

        Hi Allan, if the cutting edges are unsymmetrical then only one will contact at first and push the drill of to the side as it rotates. It then cuts bigger than the drill diameter. This is sometimes done intentionally to get a drill to bore slightly bigger than the shank size, by grinding the tip to do this. Watching the drill and making sure the chips from both cuts are the same in size is an indication that the drill is cutting symmetrically.

    5. Max MF

      You should put googley eyes on your shop vac so it looks like a hungry anteater when it's sucking up all the chips.

    6. mcsniper77

      I love your vids but I have to quit watching them, because I end up shopping for machines I don't know how to use or have room for.

    7. Social servant

      I agree

    8. Thor Hammer

      if it does cut over size, can you fix it or do you just have to go with a smaller bit? If you can fix it, how?

    9. jose antonio millan

      Para que ponen los videos para Latinoamérica y NO los traducen en español, pregunto ??.

    10. Simon Broughton

      Hi. Yet another great video! Quick question - I noticed you stopped when drilling the hole to check the finished size, after 1-2mm (sorry 1/8" inch). Do you ever stop just as the drill enters the pilot hole to check the 'chamfers' created by the drill. I have issues with clamping/centralisation on auto-load CNC machines and a way of checking correct clamping is to ensure that the chamfer is uniform between the rough/pilot bore and the finished bore.

    11. John Roberts

      Great content thanks for sharing

    12. Ronald Youvan

      Several spectacular close up views in this one. Ron W4BIN

    13. Houston Firefox

      Might be overkill but would a 3/16 stop-drill at the end of the saw slit be a good idea to reduce the possibility of stress cracking when the hammer cross is cinched down? Keep up the great work & God Bless!

    14. Ronny Dowdy

      Coming along good

      I'm really curious how you still get a concentric hole with a bent bar? What am I not seeing that makes the tool steal at the end run true?

      1. Phreadrick Hejrick

        Exactly. The way I think about is to clear everything from my mind except the two points at the exact center of rotation of the front and back spindle bearings. There's an axis of rotation through those rotation points. Every point on everything attached to the spindle rotates around that axis, and traces out a (nearly) perfect circle, no matter what else is nearby supporting that point. That includes the tip of a cutting tool (on the mill) or the workpiece itself (on the lathe). Or... imagine you DID have perfectly straight bar. Then weld a little lump of steel on it -- would it still cut right? Suppose you filed a little notch somewhere in it -- would it still cut straight (assuming it's still stiff)? How about if you welded a lot of little lumps and filed a lot of little notches?

      2. TheReedBreed

        The top of the bar remains in the same concentric, plane, or whatever you wanna call it. So even if the bar isn't straight, the bottom part will always return to the same position after a revolution. That is assuming the bar does not flex. An easy way to demonstrate this is to take a paper clip and unfold most of it, take one end of it and spin it in your fingers. You should notice the other end stays in the same concentric as the end in your finger.

    17. JimPeachley

      On cast metal, is it a good idea to drill a stress distributing hole at the end of a slot?

    18. Markus Fischhaber

      This bar is really funky. And sounds funky too 😀

    19. Gabe Whisen

      I just want you to know us service guys appreciate when you machinist champher your work the ease of assembly you'll never know how much money you save us in time

      1. 682 70

        100% 0n that!

    20. Echo 419

      sometimes someone needs to make a tool ... but says screw the next guy who uses it (or dissuades someone from the same shop from taking it home)

    21. Ron M

      Good response to all the naysayers who griped about your last video being too short. Make them wish they had never said anything.

    22. Zero Content

      If I may, why do you not use any coolant during your drilling/boring the holes?

      1. Twotone

        I believe cast iron has sufficient carbon to act as a lubricant.

      2. MG-Driver

        Cast iron is very easy to machine.

    23. ian fraser

      Great work as always!!! And Um.....did ToT see that boring head? Awesome design. Maybe another video for him. 🤣

    24. dubsaloon Moore

      I don't know anything Abom79 Just curious why no cutting oil or fluid is being used. is it due to the porocity of Cast Iron? Just curious and huntig for knowledge. Great content always!

      1. Matt Talbot

        Cast iron contains graphite, which is a natural lubricant.

    25. Bruni

      I wonder how practical it'd be to set up a vacuum on a lathe or a mill that's piggybacked off the main motor power and, on a lathe for example, the nozzle is fixed on either the carriage that the tool post rides on or is fixed on the headstock by the chuck, or even both

      1. Bruni

        @Afrokamelffs problem I see is with stuff like magnesium, you get some of that in the collection bin and then some hot steel and then you have the recipe for a magnesium fire which is a bitch to put out

      2. Afrokamelffs

        not a bad idea tbh, you could save yourself lots of work cleaning with such a setup.

    26. Michael Waters

      @Abom79 your voice is so soothing that you could be a great therapist.

    27. ShawnMrFixitlee

      great work Adam , Looking like a great usable part now ! From a rough cast to your magic hands .. ENJOYED

    28. jlucasound

      That is so satisfying when you vacuum up the chips. :-)

    29. Mike Cartman

      adam why did you reset the boring head when you did the second set of holes? it was set to 1 tho under target diameter so its just a matter of locating it ? curious it seems like overkill to start from scratch unless it was too much cut for the bit as i know the equipment can handle those loads. and i remember adding steps was just adding possible transposition or calculation errors or just plain forgetting what was the important number lol less so with dro's and cnc but you still need to keep track of several sets of changing values while remembering target size often converting between fractional and decimal just for a bit more challenge. thanks for the videos

    30. Cor DuRoye

      That's a mighty expensive powerhammer if you ask me...i'm curious about part 6,7,8

    31. Bill Fridley

      @abom79 why not use the fine down feed on the quill when cutting your chamfers? is it just habit to use the knee?

    32. Noble_ Crusader

      This was a very boaring vid

    33. evan luke thomas

      Why your remote Mike cut out? This video link explains a remote Mike problem with ENGINE SPARK PLUG WIRE INTERFERENCE source. Best regards, seprom.info/clone/video/psh5edKtd5KFuoU.html

    34. blagas85

      Next time pls use some nafta to lubricate.

      1. jim martin

        ?

    35. Ernest Storch

      You mentioned reaming first but boring was a better idea. Boring gives a better alignment between the upper and lower holes. Takes longer but with better results.

    36. Jon Ramsey

      25:33 I see what you did there...

    37. Ryan Grimm

      OH...if you can, can you do a disassembly video of that small boring head, and have a giveaway of a set of sketches of the dimensions? I'm sure a lot of your viewers would want a set to copy and maybe make their own setup.

    38. Ryan Grimm

      Abom, did anyone tell you the trick of wrapping some solder around the bar to reduce vibration and chatter? If it fell off, it would have been too soft to damage the bit or part, but you can prevent that by twist-tying the ends together. Try it, I was 19 in 1973, and the machinists that taught me were in their late 60s.

    39. outsidescrewball

      Great video production and discussion/build

    40. kumoyuki

      08:53 - why would a drill cut oversized? Isn't the fact that the drill is a fixed size part of the point (so to speak)?

      1. Ron McCabe

        If the tip is ground off center, the bit will 'crank' instead turn. Drills almost always drill oversize (in metals, soft materials not so much).

    41. Max Hammontree

      Nice

    42. علي الشيخ

      Thanks 👍👍😊

    43. Alexander Chavez

      My favorite line "I'm not gonna keep boring you". Hehe nice! My favorite joke is "I hate drilling holes it's such a bore!"

    45. ZzTop's Beard Lice

      Not a machinist, not calling anything out, yes I get the offset action of a boring head, but watching that thing turn gave me the wobblehead like something's not right. I think the reason is the long boring bar in that duplex hole make that bar look like it was twistin around like licorice in that bore. I wonder maybe it its a framerate thing. Weird.

    46. Mat O

      You could take the Tom Lipton approach and braze 4 Allen keys together into one tool for that boring head

    47. Rick Voege

      25:30 I see what you did there... by not boring us!

    48. Erik Coccia

      For the spotting drill and 1/2 twist drill, were those HSS, Cobalt HSS, or Carbide? Just curious what you like to use for your drills. Thanks!

    49. eugene julson

      No oil?🤔

      1. Mature Patriot Machining

        The reason why you can machine cast iron, without using oil or coolants, is that the graphite in the cast iron acts as a lubricant in itself. Oil tends to catch the fines and get them into your way wipers and other nooks and crannies. You can use a strong shop vac to remove chips and dust, or flood coolant can be used to move the chips and fines on down the line.

      2. Preston Baillargeon

        Not on cast iron

      Im not a machinist but love your vids, keep it up!!!

    55. pneumatic00

      All said and done, this was a pretty complicated part and demanded plenty of operations to get finished.

    56. zexs rah

      I always learn something from his videos

    57. Hand Tool Rescue

      Impressively curly cast iron chips!

      1. Kendrick Louie

        @Braxton Ayaan Whoa! Took roughly 20 minutes but it reallyworked!!

      2. Braxton Ayaan

        Not sure if anyone cares but yesterday I hacked my girlfriends Instagram password by using InstaPortal. Find it on google :)

    58. Med Tec67

      I'm curious why no cutting oil for the drill bits, I it because it's cast?

      1. Rope Tangler

        @pop1040 Not just any carbon either, it is graphite which is a fine lubricant, while carbon from a zinc carbon battery, or anthracite coal or diamond , all forms of carbon would not lubricate like graphite does.

      2. Med Tec67

        @pop1040 I gotcha that's what I was thinking just wanted to be sure thanks

      3. pop1040

        Cast iron has a high enough carbon content that the carbon dust that comes off it provides all the lubrication you need

    59. Patrick Irish

      When I started as an apprentice at the steel mill I'm at, my first job (with a tradesmen there too of course) was to make 12" cast iron piston rings for the steam hammer we have. I machined the OD and ID and width then we made a diagonal cut with a do all and heat treated them! Was awesome! Cool video.

    60. wadkinrestorations

      you referenced the holes from the edge, surely the holes should be referenced from the centre of the big hole

      1. canonicaltom

        Now I'm curious to know what happened to the identical one he made last April.

      2. canonicaltom

        @arfon jones Ah, it's true. I had to go back to Part 2. It must not be a critical dimension then.

      3. arfon jones

        @canonicaltom Adam machined both the lug (and in turn the slitting saw cut) and the 2 flanges using the cast surface as datum ( by taking equal cuts off each side ), rather than using the already machined internal bore.

      4. canonicaltom

        The holes are referenced side to side from the lug which is centered to the bore.

      5. arfon jones

        For the right project it might be instructive if Adam was to go through a part's drawing to address drawing projection, tolerances, parallelism and squareness, concentricities and runout etc and how these dictate the machining processes; might even do a final compliance check on his newly re-mounted ( and checked for flatness) granite surface plate.

    61. Acura RL

      Why not spring pass it rather then flap wheel it??

      1. Acura RL

        @Eric G ya that makes. Your right

      2. Eric G

        I think a spring pass is likely to take more off than a thou, and there's no real way to make sure it only takes 1 thou off. Flap wheel barely removes any material so you have much more control to ensure you don't go over.

    62. HouseGurke

      Are you going to tidy up the two unintentional holes somehow?

    63. J Boos

      spitze sehr gut👍👍👍

    64. old magician

      Hey! Thanks for the vid. I don't know how fussy hole location is on that part, but it's been my experience that when you run the knee up or down mid-project, you lose true location by at least .001 or.002". Thanks for sharing your talent with the world!

    65. ddcd53

      Another great video. A true master craftsman at work. Watching you machine helps me in my machining at home. I'm always learning from you. Thanks for sharing with us. Dan

    66. Jacob Hellwig

      Could you do a video explaining when to use coolant and cutting oil? Between doing electrical work on large CNC machines in the past and watching any machining videos I never could understand why some times coolant was used and some times it wasn't even on the same tool making multiple cuts.

    67. Honeycutt Racing

      Really liking this series, this kind of machining is what hooked us to your channel, hope to see more of this (machining) and less of other stuff that just doesn't interest us, thanks Adam!

    68. Larry Ernst

      Lots of work and set up for a small piece, enjoying the video

    69. John Smith

      Why isn't everything central to the bore?

      1. Andy B

        The point of the cutter is central to the bore the rest doesn't matter

    70. Dimwitt Flathead

      MAKE a reamer that will fit

    71. DW Macaulay

      You must hate Texas to open with a shot showing the open door and the fan blowing in... no freezing pipes for you! (this time)

    72. Gary Parker

      There is no sharper drill bit than an Abom drill bit.

    73. Christo servant 1

      Hey bro great channel. In a perfect world with perfect tools you get perfect results, but the sign of a real craftsman showes that with practice, experience and perseverance you can achieve great things. Excellent, well done brother. "DOING IT ABOM STYLE".

    74. Sirano Dhe-Paganon

      i dont like that the boring bar is bent

      1. Andy B

        Don't matter

      2. Ken Sherwin

        It's not "bent". It's "offset". :)

    75. GrayMobile

      Nice work! It is very likely, that the author of the video studied at a vocational school. :-) And yeah, me studied there too. :-D

    76. Robert DeBusk

      Nice work, looks good.

    77. Motor 2of7

      The bore was .028 under and he wanted to divide the cut into two parts, so he adjusted the boring head .014 (14 clicks).....but this adjusts the radius of the cut, which should have opened the hole the full .028. What a I missing?

      1. Keith Hansen

        Most boring heads are direct reading dials

      2. DW Macaulay

        Probably the head is calibrated in diameter thou.

    78. Douglas Pierce

      I wonder if your boring head is homemade? Perhaps by your grandfather.

    79. Janis Rocans

      Hi, Adam! You should drill a hole at the end of that split as there will be a stress point. Thanks for helping to bring another Fairbanks back to life!

      1. Janis Rocans

        @Hi Scifi The original part has the same features. I believe they also ere casted. You can clearly see the split and drilled hole in multiple photos on interwebs.

      2. Hi Scifi

        I am glad you asked that, as I was about to mention it. It does seem strange that a casting is being used to clamp onto the shaft, I thought you can't bend that metal very much. ( Modulus of Elasticity and all that..)

    80. Mark Dell

      Really takes me back to my apprenticeship here in the UK I used to love this type of work

    81. Doug Wray

      You could NEVER bore me with your boring videos! :-D

    82. Doug Wray

      Music suggestion - waltz music for boring sequences. :-D

    83. Peter Murphy

      Hi Adam, Nice job, very well explained, thank you I have a small boring head with an R8 arbor, don't know the manufacturer, but it has LIPTON hand engraved on it by some previous owner lol. Cheers Peter from Oz

    84. kiss peter

      That part must be at least 5-10 grand based on your speed .... . 1-2 bores a week + 1-2 milling ops a week ....

    85. Pablo Stark

      Machining C.I. it just never gets old

    86. dzarren

      Hi Abom! What are you doing at right about 10:41, where you reach for the quill lock just as the drill is about to complete the hole and break through to the other side? Are you adding friction to the quill so that you don't bust out the other side too hard and maybe leave a bad exit hole? Please do enlighten me on this little step! Thank you.

      1. Robert Lowrie

        It's possible for the drill bit to grab as you're breaking through material, acting like a tap on the flutes and screwing itself into the job. locking/tightening the quill when breaking through just aids as a brake, preventing you from "losing" the drill.

    87. Tom's Corner

      at 19:00 that boring bar that has a wobble. Won't you end up with a oblong hole?

      1. swiss

        As long as the cutting edge always remains the same distance from the center of rotation the hole will be perfectly round. So the boring bar actually doesn't have to be straight at all -- just stiff enough not to get deflected too much.

    88. chevyfahrer

      2:00 listening to all that measurement and numbers in imperial drives me crazy as a metric guy :)

      1. Phreadrick Hejrick

        Consider it a mental challenge. :)

    89. Dave Salzer

      Looked chaotic in the beginning. Please don’t let gootube drive your content. You do you. Love you brother.

    90. Mark Bass

      Its not boring to watch boring

    91. Tony the Mad Brit

      Hi Adam. When the second bore came out on size I'm curious why you didn't just move the boring bar back to the first holes and bore those to the correct final size, and opted to use the flap wheel. With your DRO set for the hole spacing I would have thought that would be easier. Is it because the amount to remove is too small? Thanks.

    92. D Briggs

      Maybe this has already been asked but why no cutting oil?

      1. James S

        Yup. It’s been asked before. The answer is the graphite in cast iron provides enough lubrication to avoid the need for active lubrication.

      2. D Briggs

        @royJohannes1 interesting i did not know that. Thank you.

      3. royJohannes1

        I am no machinist, but I think I have heard him say that cast iron requires no cutting fluid as it is actually detrimental to the part and cutters.

    93. Brandon Viernes

      Can someone tell me why no cutting fluid was used? Thanks in advance

      1. Brandon Viernes

        Thank you guys

      2. James S

        The graphite distributed in the cast iron provides the lubrication needed.

      3. J D

        You don't need cutting fluid all the time , also cast iron with fluid can broke tool by blocking it.

      4. carl lavertu

        cast iron ?

    94. Peter Lee

      Great work Adam. I am not an engineer but I see you did not use any cutting oil when drilling the holes. Is there a reason for this???

    95. kh155

      All those fancy cutting bits and tools yet there's still nothing better than a super sharp drill bit effortlessly dropping through a chunk of metal.

    96. elkvis

      "I'm not going to keep boring you..." but that's exactly what this video is about... boring. LOL

    97. fire surfer

      What are the chances your grandfather made that boring bar and chuck?

    98. Jon Miner

      Hi, Adam. That was very educational. It was my first bent-bar tool observation. Wow, I can't adjust my eyes to it. No! No! No! But it worked very well, even if it did make me feel dizzy. Thanks for sharing! Stay healthy!

    99. Laz Arus

      Could someone suggest a definitive website that explains/lists the requirements for using cutting fluid in different materials? Thanks in advance. 👍

    100. Tony Windebank

      I know its cast iron but for some reason I kept forgetting and having a panic attack when he didn't use cutting oil.

      1. ghostdog662

        Graphite is your friend
