Well in my adventures in shade tree mechanic post, I mentioned how I had a broken stud on the front of the tractor holding the axle support bracket. Well I had to renew the pin, so I yanked the axle support bracket to beat the daylights out of the pin. The bushing was worn through and only half was left. The axle was wallowed out. Since I had to wait for parts to arrive, I figured here was a chance to yank that stud. I bought an expensive Tungsten Carbide bit, but at 1/4 inch was too big to get any good pressure form the hand drill.....sooo....I chucked up a masonry bit for a TAPCON. It's got a narrow Tungsten Carbide tip. I used copious amounts of cutting oil and put the drill in hammer mode and burned through the center of the hardened stud. I went all the way through in case I broke the easy out in the hole so I could drive it out from the other side. I had soaked it in PB blaster for days, and now and then a little heat from a blue bottle torch. With the easy out in, I applied moderate pressure and it moved 1/64 of an inch. I soaked it in PB Blaster again, then went and had a cup of coffee......came back and eased it on out.
Then did a little happy dance!
