I broke off all four half inch bolts in the two inch plate that the spindle welds in to on the corn picker. Only one was flush,the other three were recessed a thread or two. I welded a 3/8ths washer to the one that was flush,welded a nut to it,rapped it a few times with the impact and he came loose.
The ones that were recessed were a little tougher. I laid the washer over a hole in the anvil,put a ball peened hammer in it and hammered them in to a dish. I laid them over the holes,very carefully got the welding rod straight down in the hole,then just let it burn and pile straight up to the washer and made a swirl in the washer to finish them off. Being dished,they stuck up above the plate enough to get ahold of them with a pair of curved jaw vise grips. I tapped the vice grips with a hammer for about half a turn then turned them on out. One came on the first attempt. The other two,the washer broke off and I had to try again,but I got all four of the buggers out of there with no drilling.
