BRAVO my friend, a stubborn swing arm pivot bolt caused me to miss with the sledge and put a chip in the engine case, only small but still a huge regret and well now i know how im fixing it :)
good video, you built that surface back up to be a protective cover over the engine using only a blow torch and a dura weld stick! ... Well done! You inspire me to be more daring! Saves on having to buy another part!
In this video i use durafix rod, many similar products in ebay, you need map gas, is a mixed formula with High thermodynamics efficiency, is a yellow bottle.
I think you melted the hole, so that there was a cut in the video ... but then you gave it your way, I think you stood a plaque below the hole and finally managed to slap it, so that the repair end was much larger than the first, but the video was good, better than the videos meaningless Durafix staying welding pieces here and there completely out of everyday reality ...
