I hope your insurance is paid up, your widow might need it. Those chips can be downright explosive. And whose the insurance company that allows that? I have personally seen a 6 cyl mercury outboard block welded up where a con- rod went through it, with a smith wrench yet. But since the block was also so badly warped from overheating that it couldn't be line bored for a fresh crank, he after he had welded it very professionally and serviceable looking, proceeded to warm up his weld a little more to show us frogs what happens when you get cocky. Good thing he was working on the sidewalk in front of the store for this particular demo, cuz he had to warn off the fire dept when they arrived. So it just burned with lots of smoke and a very bright flame, leaving a 6' section of sidewalk that had to be back filled in and a new one poured the next day to placate the city, Iowa City IA to be exact. This guy had welding certification cards in his billfold that when unfolded was about 4 feet long. Good teacher, and to this day my favorite stick em together tool is a smith wrench. Nothing I've put together with it has ever come apart again unless I took it apart, usually with the same wrench but a cutting torch screwed in. -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
