Any length of bolt is now achievable. This same technique is used in shortening car axle shafts that handle 100's of horsepower.
Tools I used in the video:
Vise Grip C clamps 11" total length: amzn.to/2MTR0ik
Milwaukee M12 3" Cutoff saw: amzn.to/3rKK2ew
Milwaukee M12 R-Angle Die Grinder: amzn.to/3rMaDbc
Miller Multimatic 220 AC/DC multiprocess welder: amzn.to/3tOJZQE
VIDEO THOUGHTS
Mig it and be done is seconds. You can also Flux Core, Oxy acetylene, or even stick weld if it's big enough.
Don't Quench:
Why? because you will never match the factory hardening process in your garage and will worse case make the bolt fragile/brittle. Sure allowing it to cool slowly naturally is going to make the metal soft, but that's like saying I only want soft rocks thrown at me. It's still strong/hard. It will just bend or stretch easier vs snapping. The shaft of any give bolt is over 25% stronger than the thread area as it has 25%+ larger surface area. Not having it tempered properly is not going to reduce the strength more than this.
