Thank you for posting. Watched tons of videos and read lots of articles but your video was the one which finally helped me remove my rusted carriage bolts!
Thank for posting. But mine are much bigger bolts & nuts. They are high quality metal, ATG Nickel-Based Super Alloys Kim X. Even trying with a blow torch will not melt them.
You can come here and try to cut these bolts & nuts for me. Oymyakon temperatures are in the 20's. Winter gets very cold. It's below -50's, where many bolts will not hold up.
