[@sphillips6357]

If I was 30 years younger I'd come work for you for free just so I could learn. Unfortunately I learned to repair office and commercial/industrial equipment. Tolerances there, too, are plus or minus .001 and some adjustments had to be done by feel as there was no way to possibly get any type of gauge in there. That equipment no longer exists and is now all obsolete, just like my skills. I hope your assistants know how blessed they are to learn these skills from a master tech like you. I know from trying to teach some people many years ago that some people just never seemed to grasp the concept of close tolerances. And I've found that true of some machinists too.

When I was 21, I was a E5 USN Submarine Sailor. I was married and had very little extra cash to play with engine mods. My 67 Impala, 327 at 75,000 miles killed a cam and needed to be rebuilt. Damn Quaker State Crap Oil!!! Devastation! So, being mechanically inclined and a DYI guy, I did the engine rebuild my self. Lucky for me, I found a local machine shop in a small town in CT that had a heart and good engine machinating skills. It was Larrys Machine Shop. You remind me of the owner. Knowledgeable, Kind, and SMART! I can not believe all the LS Engine knowledge that you have provide me. THANK YOU! You are the MAN! Bill

That’s near and dear for me, thanks for saving some good iron! Years ago I bought a 454 block, steel crank and rods out of a boat a boat that blew an oil cooler line and was driven with no oil pressure until it locked up near the shore. Seller sold it to me for scrap. The center main was spun so bad it bulged the cap out really bad and was completely black. Since the cape as wasted we snagged another from a scrapped 396 and worked on that thing all weekend. Definitely burned the “midnight oil” line honing that thing to accept some over/under bearing shells. My buddy ground the crank under, .020” mains, .010” mains rods while I squared the block up, zero decked and bored .030”. 20 yrs later still running as a daily driver that sees the 1/8th on some weekends and get the kids to school during the week :)

Thank you so much for this video. I'm fixing an engine that had spun 4 rods and a main. I got a new forged crankshaft and was planning to reuse my block very ignorantly and the new crank would not spin because the number 1 main that had spun was oblonged causing the bearing to crush the crankshaft journal on the sides and not allow it to spin. I spent a whole 2 minutes peening it like you did but with a ballpeen hammer instead of an air hammer and I can now spin it with one hand. Seriously this video saved me from getting a new block. When I'm done blowing all my money on rebuilding my motor I'll have to send you a tip cause this saved my block.

You are setting the bore gauge up to the size you want and hone the bores to the size you want. That's why the reading on the gauge got smaller. Right? I know this is probably something everybody else knows but I've never been around this kind of stuff and was just trying to figure it out.

At Pete's machine(when I was a kid working there), Pete had align boring equipment where he could recut, or align cut all those caps. Now Pete would make sure all the oil galleys was clear, open and clean so oil would flow as needed in the engine. We use to use blue Loctite on the crank cap bolts to make sure they stayed where we torqued them. Also Pete had a crank grinding machine- seems there was always a crank in the machine getting reground by Terry back in those days.

During my time in the older way with repairs involved heating and brazing the blocks and caps after we bored the block to create an area for the mass of brass. Hand filing a peening everything until the block was good with blueing. Clip the caps as usual for the boring. At times we would finish hone if we had rough finishing.. Sometimes we'd have to really bore big and make soft steel sleeves and with push rod those in the block and replace the cap. There was always a way to get it right again. Some of it was race stuff and still used when the boys had no choice.

Keep in mind if the block sees enough heat it will occasionally crack, usually in the oil supply passage area.

[@frotobaggins7169]

I'm sure this is a dumb question but...Wouldn't it make more sense to machine it with the block on the top so the weight of the bar and gravity are cutting the caps more than the block? This way it seems like the block gets more material removed just due to gravity. I get that the idea is that it's cutting both sides so it's splitting the difference but with nothing to guide the bar other than the mains, it seems like just by nature it would cut the block more than the caps. I also get that the machine is using the block as the reference so flipping it around would be very complicated. So maybe it's just for simplicity's sake. One other question is what effect does the shortened distance from the crank center line to the cam and deck have? I get that it's only a few thousandths but that is also what we are removing here.

[@powellmachineinc]

It doesn't work like that, but more info than I'm willing to type

You need to wear gloves to protect yourself from the cutting fluids, as they do cause kidney cancer. As a lifelong machinist, I was diagnosed with kidney cancer in my mid 40's.

One idea that was floated once was spray welding the edge of the cap to take up the excess clearence. Then reinstalling and align honing it all. Not a professional so making no claim as how legit that would turnout. Interested in your thoughts. Just a back note, was relating to a Rover/Buick V8 and they often get loose on the main caps, sometimes just rough installation. Another idea was using a water jet cutter and making a set of new caps to suit. Never went that route but bit of out of the box thinking.
