Broke my water pump bolt. Now what? (Update - broken bolt is out)

Still working the problem. Heated it up again, more PB Blaster, cooled it, tried to turn with a vise grips. No luck - wouldn't budge. Have totally buggered up the threads on the shaft. Before doing this, tried to fit an extraction tool on the protruding part. Not enough length to make the connection. Next step - drilling it for a bolt extractor tool. Going out to buy left hand drill bits.
Cruiser, left hand bits won't do anything at all for a bolt that is stuck that hard. From what you have said in the last 4 pages, there is NOTHING you are going to be able to do at hour home with what you have available. Let's be honest and think about your options.
1. Find a mobile welder who will come to your house. Have you looked yet? There are several here in Topeka.
2. Make some phone calls to some mechanics (smaller repair shops) in your area. You may very well find someone who will come to your house and remove it with the weld on a nut technique.
3. You have GOT to have a friend with a truck. Or you can rent one for a day. Then rent an engine hoist. Then use something for padding (old tires or something) and put the engine in the back of the truck and take it somewhere. You keep saying you have no way to get the engine to a shop, but, forgive me for being blunt, that is not true. You CAN rent or borrow a truck. You CAN rent or borrow an engine hoist.
It's time to figure out a way to either get the engine to a shop OR have someone come to you.
I have a good Miller welder. But if I didn't, I know several guys with welders who would be more than happy to bring it over and help me out. I also know a bunch of guys with trucks who would be glad to help. Do you really not know anyone with a truck, welder and/or an engine hoist?
@1WildRT, @RustyRatRod and @toolmanmike are right. It's time to assess the situation, formulate a plan and execute the plan!
