      One way, and idk if it's the proper way, to part something in a lathe; is to hold a screwdriver in the center hole and send your cutter all the way through. I've also seen the hack saw method with the lathe turning very slowly.

      Swaging also affects 360°, so you are adding clearance where its not needed, scraping only adds additional clearance to the needed area. Big Block Chevy's that run hard also have cast iron core shift issues. Using coated bearings... forcing a cam in will remove the coating on the high spots... or, there's always Prussian blue. Scraping offers superior results, done right. Bore scope might be handy, picked one up off A**zon myself & fix-n to maybe use it in the near future scrapin cam bearings. Video of the work on the aluminum cylinder heads you did impressed me, ending in ice cream even better.

      Unfortunately Mopar Action magazine has gone belly up I just seen in a very recent video on RUclips because the investors decided to pull out because they were mostly selling the magazines on book shelves at news stands and at Walmarts book stands and not many were being sold plus a lot of the car oriented material now is being streamed on RUclips or other platforms and people seem to rather do this than buy a magazine or magazine subscription and actually read the content which I like to read because I enjoy reading . I had bought a Mopar Action magazine from a Walmart book stand & was going to subscribe like I did many years ago 90s then it had gone under but now I'm glad I didn't because some people were saying that they had paid for a magazine subscription just now and didn't get a refund & got burned . UTG just did a video of him and the guy just after the announcement of the magazine going under again I had seen this but I haven't yet sat down to watch it because it's relatively a long video but will get to it once I'm cought up on my own projects lol . I do know that some engine builders use cam bearing knives to scrape the cam bearing if the cam fits tight especially on the Chrysler engines but I've built quite a few of them & yet had any problems with the cam bearings fitting so tight the cam won't turn & I feel that part of the problem is that the cam bearings aren't being made to quality spec standards probably because they are probably made in China now & quality control has dropped just like what's happening with a lot of flat tappet hydraulic and solid cam shafts and lifters that aren't ground correctly or the steel used is too soft because of improper heat treating for hardness that we are seeing & hearing about quite often now with cam & lifter failures even when using the correct amount of zinc added to the oil .

After this time it is stable and candidate for remanufacturing. Resulting in a better engine than bran spanking new.

Your basically making the cam a cutter. Stick it in, rotate one turn and pull out. It takes off all the high spots. Some guys have been doing this for years and years and thats how they correct the issue and thats how i was shown when i ran into my cam not turning for crap.

    I'm going to give you a TIp as someone gave me ... Take a small rod that fits the oil hole in the bearing or a two-stage hole that fits the case and then lower down one that fits the bearing hole. When you put the cam bearing in the rod will fall in the holes if you have them correctly aligned. I use this technique when I build the engine from the case.

    My family had a Corvette-only sales, service, parts department, and body shop. This comment is about the machine shop that we used, they had built a small block Chevy engine that was fully dressed, with heads, intake, carb, water pump, and distributor, and had it sitting on an engine stand by the door. One day we were picking up a block and the owner said to my brother, if you can pick up that engine (the one on display) and carry it out the door he could have it. So my brother walked over, picked the motor up, walked out the door, and set it down in the back of his truck. Immediately the owner started crying that he was just kidding and that he didn’t mean it, despite everyone that was in the office calling him out on it. He got his guys to get the motor out of my brother’s truck and we never used that company again and as the story spread, other people stopped using them as well. I’m not saying he went out of business because of us, we wouldn’t wish that on anyone, we’re not that type of people, but he was closed less than a year after the incident.

    When you’re turning on a CNC lathe….anytime you change your speed or feed or both, it will affect the size your cutting.
    The faster you go across the surface , the less shallow your tooling grooves are which results in a larger O.D. The slower you go across a surface, the deeper your tooling grooves which results in a smaller diameter. Same goes with the tool nose radius of your insert…smaller radius makes smaller tooling grooves (also known as cusps).

Had the camshaft spray welded, and then i made ampco45 bearing bronze inserts on my old monarch, pressed them in, then had the head line bored and honed. Cam shaft speeds are typically perfectly fine with ampci brinze and it's way easier to line hone bearings than fight with press fit, line bore,,finish size.

    Don't cringe but I have used the old cam to make a fine cut reamer to remove a little metal from the interfering part of the new bearing. I had done this on small block Fords and small block Chryslers. It worked well if you just went slow and careful. These motors were generaly run hard and never experienced any problems. I like your broach system better, more precise. Once an experienced builder told me, if the old cam bearings were good to not hot tank the block. Just clean with elbow grease and solvent since the hot tank would destroy installed cam bearings.

We also flapper wheel the bearing housings as Chrysler used a rock and cold chisel to machine them in the first place.

    Not your typical Dad & Dave situation, very interesting, informative but of your comments got stuck with me , " things I've been doing WRONG all these years", a very harsh word to use weather it be towards yourself & not that you did but towards someone else, I myself have used extensively in the past & have learnt over the years that it puts people off or in a state of limbo so I started to say " not right " , not quite right or not correct. So in short I have found the outcome much more rewarding for others & beneficial in business workings . Thank you guys .

    The swedge or burnish tool idea was brilliant. A little take it or leave it advice. Your CNC probably has a feed-rate override. Maybe something like a rheostat knob or a up/down button. You can slow rapid traverse during set-up. Creep up to work-piece. Lessen the pucker factor.
    Also, your lathe probably has mutliple on screen read-outs. Location of tool, etc. A 'distance to go" read out is useful when setting up. A 'how far until next line of program' distance. If distance to go reads 3.00 inches in Z axis and your 1.00 inch from work piece, you'll know there's a problem.
    Also, when setting up work as you did here, fairly close tolerance, allow for two finish passes. Say, mild steel, leave .030. Take half first pass. Mic and offset down remaining pass. Two equal passes allows for equal tool pressure. Many factors determine tool pressure. Size of work, distance from chuck, etc. Ok, good job. Thanks.

    Back in the day, we took a old cam, and milled a partial flat, at about a slight angle to the centerline of the cam, to get something similar to a single flute, on a reamer, on the camshaft journals, then sharpened the cutting edge.
    Looking back, not sure it was right, but it worked…

This was fun to watch, you two are very blessed to have the (well I'll just say it like I see it), love and respect that you have for each other. We came up with some pretty unsophisticated solutions about 1 or 2 o'clock in the morning occasionally. Of course we couldn't even spell CNC. I'm 75 now, and I still miss him.

    I've built several big block Chryslers and they almost all had tight cams. The first one was a back yard build and I spun the cam in pretty forcefully and then hand scraped and polished the tight bearings where they shined up. Slow tedious process and I didn't like that so I made me a tool from an old cam on the next one. Used a cutoff wheel on a Dremel tool and ground a diagonal cut across the 3 middle journals. I ground them on an angle into the journal to form sort of a "blade". Lube it up and gently turn it in with a wrench with just a slight pressure in. Sometimes they make a bit of shavings but usually just a smidge in the groove. Seems to make a nice finish on the bearing without scratching it up. I did take my time making the grooves and cleaned them up to a smooth blade. It works very well and fast too with no special tools. I think I've used it 4 times so far.

    When I was a zone rep for Chrysler the story of after installation cam boring was common. I have not watched the video yet but another truism was that the shop manual was off 0.001 for the number 4 bearing and always had been.
    We had tooling plates that set the distance between the crank and the cam tunnel and tooling that would align either the cam tunnel bores or the bearings exactly. We could overbore for larger than the small Chrysler bearings or for roller bearings and adjust for main align bores
    we could also od bore the cam journals so we could feed from a not bottom of the bearing location
    Now to watch the video and see what you came up with cheers

    My old boss was a mechanic who worked on building the cameras for the U2 spy planes. The Tolerances were typically always within 5 10 thousands of an inch.
    but before each day started they ran the machines for 20-30 minutes to warm -up before cutting in order to get consistent and accurate cuts.
    When doing such accurate work you may considerer this,

    Last comment I promise.
    The material you are broaching can rebound behind the tool so it can be smaller than the broach size. It can also actually work harden the material.
    We used to do it with balls through the piston pin bore

    It was amazingly interesting and informative and entertaining.
    I have been with your channel for about three to four weeks now and I absolutely love it!!!!!! You both are so inspiring and talented to watch and come up with ideas like on this Chrysler cam bearings.
    The CNC machine was so very nice to have to make the tool. My compliments to you both.
    I agree with dad that it is good where it is and would not try resizing it more. Believe it will run just fine where it is. End of that chapter!!!!!!!!!!
    Will be anxious to see more work done on this motor and eventually see it run-yeah!!!!!!!!
    I really enjoyed watching what you did and how it came out. Enjoying your channel.
    Your CNC machine is paying for itself.
    Looking forward to the next video. Thanks for everything!!!!
