    I haven't done lathework in years and this takes me right back! This is what impresses me the most, guys like yourself who find solutions to tricky jobs. Your methodical approach and equipment available transforms machining into true art. Love watching a master at work. :-) Thanks for taking the time to film it.

    • @Abom79
      @Abom79  11 ปีที่แล้ว

      Thanks Ross. I don't consider myself a master but I've had a lot of experience doing odd job shop work, so I've gotten pretty descent at figuring out how do do a job in some form or fashion. The piston job was fun and gave me even more experience in doing tricky set ups.
      Glad you have been enjoying my videos!!

    Been watching your vids for a year or so, but missed this series. Just wanted to say it's neat to see how the shop has evolved over time :-). Even see the face plate for the welding table sitting there waiting for the future! Nice work!

    Another great video. Thanks for sharing again! The ‘Adam-Cam’ is a bit like riding Mr Toad’s Wild Ride at the carnival except with one loose wheel and no seatbelts..but once I threw up a little the rest of the video was much better.. all kidding aside, those of us with old eyes love a steady camera mount.

    Thank you for putting your videos on Utube Adam. I do not have a lathe and have never done any kind of machining. I have had an interest in this area for a long time, but I have not really had the time or opportunity to get into basic machining as a hobby. I work in the medical field, so it would be a fairly dramatic change of occupation should I ever get into your line of work. Actually, the way you are such a perfectionist, and the way you are able to jockey things around to make it all work.....these traits are similar to the way I go about my work every day. The approach to our professions may be comparable, but ppl in your field might lose part of a finger, whereas I try to put said piece back on....:) Thanks again Adam, I really enjoy watching the unique and professional way you go about your work. I cannot believe how easy you make it all seem. Of course, I think I have a pretty good idea of how much time, work, training, and years of experience it took for you to reach the top of your profession. I hope you are proud of the fact you possess skills that only a few will ever know. Great work Adam!

    Bringing back the dead on this one, however you are dead on with the fly cutters. Ive used them many times doing valve reliefs, just grind my insert then cut away. Also I made a jig for valve to piston angle so I can chuck it and cut it. Since you don't do alot of automotive might not be worth your time do make a setup like that. Love watching your videos, I do automotive machining, never any of this big stuff like you do. Great to see the worlds meet.

  • @KnolltopFarms
    @KnolltopFarms 9 ปีที่แล้ว

    Wow, what a trip it is to see the differences in the shop and also what was really a gas was seeing the face-plate sitting against your toolbox instead of it being a brawny table top, LOL! Thanks for the show as I go through some oldies to fill in some blanks, Aloha...Chuck

  • @bcbloc02
    @bcbloc02 11 ปีที่แล้ว +7

    Also you usually want at least .050" of clearance greater than valve diameter to allow for piston movement in bore and valve growth from heating.

    • @Abom79
      @Abom79  11 ปีที่แล้ว +1

      Thats why I called and talked to the mechanic before I cut it.

    subscribed! I love channel Adam it satisfies my deep itch as I myself am a former aerospace machinist. i appreciate your attention to detail and knack for"doing things the right way"we know both you and I there's a couple correct ways usually for a task but i feel like I'd be working with another me if we were in a shop together. very precise. aerospace doesn't tolerate 0.0005 as good enough but that's implied of course due to the nature of it. no side of the road at 35000 ft. anyways keep it up i loveeee that you make long videos. I kick back and hit auto play

    Hey Adam,
    Really clever thinking man. I love to see how you experienced guys think about solving a problem the requires 3D thinking and clever thought-out setups. Also like the way you convert metric to imperial to be able to work with the dimensions in the "language" that you prefer. Don't worry us metric people have to do it the other way round!

    • @Abom79
      @Abom79  11 ปีที่แล้ว

      Well I prefer everything in "inch" dimensions, but have to deal with metrics quite often. I have charts on the wall that converts everything into decimal for me, so I always know what numbers I need to hit with the mics. Plus the digital calipers are a huge help too!

    Hi
    Adam
    Great video with some good set ups
    Those Ikea lamps are very handy (I should be on commission)
    I well remember "pocketing" pistons using the engine for set up using old valves with carbide inserts brazed on
    Pushed down the valve guide powerd by a electric hand drill
    A simple collar set the depth
    Regards
    John

    • @Abom79
      @Abom79  11 ปีที่แล้ว

      Hey John, I seen theres tools you can buy so that guys can do that themselves using the heads as the guide, but just looks a little sketchy.

    • @realworldmetal67
      @realworldmetal67 11 ปีที่แล้ว

      Abom79 I agree. However, I would be a little nervous about putting any pressure or tension on either the skirt or the wrist pin bore. In such a situation, lacking an actual automotive machine shop, I would be inclined to either use a dummy rod and cylinder or grab it with a 3 jaw chuck and then mount it in some fashion on the adjustable angle plate. I only say this because in my stock car racing days with my dad, those are two places we don't touch with anything other than the wrist pin and the cylinder. Just my two cents.

  • @DrMerkwurdig
    @DrMerkwurdig 11 ปีที่แล้ว +2

    Thanks for sharing! I never thought of using a flycutter for something like that, but now that you've pointed it out, it's obvious. I'm going to pick some up on Ebay now :-)

    • @Abom79
      @Abom79  11 ปีที่แล้ว

      Them fly cutters come in handy for many jobs. Make sure you add a couple large ones to your inventory also, they work good for machining a wide surface.

    • @johnwilson3668

      I have just started watching your videos and concluded that
      you are a highly skilled and meticulous engineer. Your
      videos are excellent . I am a retired jig borer /miller of 49 yearsof experience . I don't want to be condescending but I would like to share a trick I used setting fly cutters on the milling machine .This method depends on how accurately the head is set as in the case of a Bridgeport. I have used this on small diameters in a facing head and up to 2 feet diameter on a boko jig borer in a large fly cutter. This can be done before the job is set or after if you prefer. A digital read out is preferable but not necessary. I have succeeded in plug gauge accuracy
      First place a tap - in - fit piece of mild steel in the bolt slot in the milling machine then pick up the front face with a 1/4 inch edge finder, then move 0.125 to find the edge ,zero the readout .
      The next step is to move the radius of the diameter required
      then insert the tool in the fly cutter and tap until the tool is just scratching the face. If the job was set first it's only a matter of
      keeping a note of the figures without loosing your position .I have
      used this method where a quantity of components have to be machined and tool wear is inevitable . I have written this in more detail than you would need, this is for the sake of new machinists
      I hope this might save you some material on the lathe
      Keep up the good work .

  • @billyc2572

    also, if you sunk the wrist pin dowel right in the t slot groove, you'd be square on that axis right off the rip. then just touch off and you're the man!

    One last thing, Intake valves are the larger diameter. LOL. I know you know that, but had to rub it in.

    I trained as a turner in the 1970's, way before CNC was around (I don't 'do' CNC - LOL)
    I trained on all machines but 'specialised' on lathe work, (mainly to make and modify motorcycle parts, been working on bikes since I was 11yrs old)
    I'm always fascinated by your methods. If you are going to modify more pistons in future it would be worth making a custom clamp. Personally I turned a square of 3/4" thick aluminium plate to register inside piston skirt and made a yoke to fit inside with bolt through back. Still holds on pin but makes moving from lathe to mill quicker and easier. (also has various locating diameters for different pistons)
    Have to comment on your clutch mod next, wondering why 'Rob' want's it locked up?

    For a better grip, you might want to put a cove on the underside of the strap clamp to match the drill rod going thru the wrist pin.

    Hey Adam,
    Whats up with the gooseneck oil can? Did you sell all your Eagle 66's on ebay;))) I really like the your Taft Peirce plate. How did you get the wrist pin aligned with the machine or is that in the second video?
    Talk to you soon.

      The Taft Pierce angle plate is really nice.
      In the second video I show the indicating. I did it the way that I thought would work out and hopefully I wont get flamed too bad on it.
      Part two should be uploaded later tonight.

  • @bcbloc02
    @bcbloc02 11 ปีที่แล้ว

    For your fly-cutting I just use a boring head. Then you just need one radiused cutter and you can adjust for any size valve you want to do and can cut for any clearance.

  • @jtkilroy
    @jtkilroy 11 ปีที่แล้ว +1

    Taft-Pierce? Hell yeah thats a nice angle plate. I am sure the new cost on something like that would be $2K+. Very nice work as usual Adam. BTW, sure isn't hot up here, down below freezing every night, not good.

    • @Abom79
      @Abom79  11 ปีที่แล้ว

      Taft Pierce made some damn fine machine shop tools. Yea this angle plate has always been a nice item and I was very happy to finally get all that surface rust, and years of shop crud cleaned off of it. Its still in great shape!
      I think that cold front has stalled out in between you and I James. It moved through yesterday and was in the 40's, then moved back north again and its been in the high 70's today......sheesh!!

  • @1-shotslinger108
    @1-shotslinger108 6 ปีที่แล้ว

    The way we did it in the Harley shop [ with no milling machine] . Braze a tool onto an old valve and place it in the head -- bolt head on mark stem of cutter for depth and machine fly cuts right on the motor.

    I was wondering about clearance like some of the other viewers I guess we will see that in part 2. That piston is pretty big must be from a single cylinder motor. The ones on my 750 DOHC Honda are only 62mm! It's good to take unusual jobs I think that is a good way to stay sharp and learn.

    For those who are interested those "double boost" lights are from IKEA. They had a sale on them in amazon 6-7 years ago for $7.95 I bought 40 and placed them on a pancake magnet and on every piece of equipment I have as well as my reloaders.on a few I mounted them on micro lead acid batteries for trips to attic etc. Great video as always. How much did you end up charging for the valve job if I may ask?

  • @PLUSHAIRPLANECARPET
    @PLUSHAIRPLANECARPET 11 ปีที่แล้ว

  • @shanegill25
    @shanegill25 8 ปีที่แล้ว

    On your fly cutters, have you thought about insetting a small magnet into the bottom of the slot to hold the cutter tool flush against the head while you're setting the diameter?

  • @mainemikeiii
    @mainemikeiii 11 ปีที่แล้ว

    Assuming theres no runout on the valve shafts... couldnt you chuck them up in a drill chuck or a collet to find center??? Probably no where near precise enough, but just wondered really what your thought on it was... great vids... thanks for taking the time to share with us all!...

    • @Abom79
      @Abom79  11 ปีที่แล้ว

      He used the valve guide holes and used the transfer punch so I would know exactly where the center would be. No guess work there.

  • @Dan.Whiteford
    @Dan.Whiteford 11 ปีที่แล้ว

    That looks a kind of tricky project with all those different factors to consider!
    Also I would think that bcbloc02 has it correct (below) when they make the point of the need for extra lateral clearance for heat expansion and piston movement. Don't I remember you taking measurements off the valve heads direct?

    • @Abom79
      @Abom79  11 ปีที่แล้ว

      In the second video I correct the diameter of the fly cutter after making a call to the engine mechanic.

    • @Gottenhimfella
      @Gottenhimfella 8 ปีที่แล้ว

      I was surprise to see Adam setting the outer cutting diameter of the fly cutting toolbits to the same size as the outside diameter of the valves.
      I would have expected him to set the centre of the radius of the toolbit tip to that diameter, because the corners of the valve are a lot less rounded off than the toolbit.
      I guess it must have worked out OK though; maybe the pockets were deep enough that it cleared anyhow?
      Or maybe he increased the diameter setting in the next clip, which I haven't yet watched.

    got em all. And yes I do have a 1923 Ford. So dont feel bad, half of work we do I have no clue what it is or what it does. Just do what the customer wants. BUT fear

  • @spantosix9
    @spantosix9 7 ปีที่แล้ว

    I have a better way to set the angle on the fly cutter, used a edge finder on a collet pick up the edge off set of jaws on the vise on any angle plate,1-2-3 block chuck on the vise ,once your edge is picked up zero your axis on the display or the dial on the handle and come out the radius that you are trying to set the diameter for remove edge finder off the quill install the fly cutter on a collet loosen the bit cutter put the spindle on neutral come out with the cutter to pick up the edge on whatever edge you picked up with the edge finder. Hope I explained myself good enough Machinist are not the best communicators or a V block and a height gage
