I changed the doorknob to my room. IT TOOK ALL DAY. 3 trips to 3 different stores (Target, Home Depot, Wal-Mart). Original purchase: Replacement doorknob. $9.99. Good deal, right?

Get home. Realize I will need to do some drilling. Get out the old drill and find both batteries dead. Also find out that I need to drill some BIG holes, and we don't have any bits for that.

Home Depot. Find a nice set of spade bits. $9.99. Good deal, right? The cheapest corded drill I could find: $39.99.

This job is getting expensive.

Ok, now I'm good to go. I drill the hole in the side of the door a little bigger and it works perfectly. Now, time to install the knobs ... uh-oh. The tiny hole my previous knobs used is not sufficient. The new knobs require something like a 2 1/2 inch hole, and the biggest spade bit I have is 1 1/4. Great.

I try to improvise, using smaller spade bits to try and make a nice big round hole. It doesn't work very well because spade bits are designed to drill straight into something, and you can't really get any side-to-side motion to smooth things out.

In the meantime, the whole reason I'm replacing my doorknob is because the previous one didn't latch well, which was fine until I got cats. They like to push the door open and get in my room and eat things they are not supposed to. They have been throwing up various things today but I think it's all out of their system now. Gross.

So now I'm stuck, until Caleb finds some cat barf on his bed and doesn't have a spare sheet set - giving me an excuse to go to Wal-Mart. I get there, check the hardware section, and bingo - found some drum sander bits. I get those and a set of the big round toothy-looking hole cutters, just in case.

I stripped two out of three sander bits, but 45 minutes and a whole lot of sawdust later, I have a new doorknob.
