The old diving board must go. Unfortunately, the weathered, rusted bolts holding it down were frozen tight. I'd tried WD-40 in the past with no luck. I didn't want to spend a lifetime burning through reciprocating saw blades trying to cut through them. This was the perfect project to try a new technique, fire.

We're probably not going to replace the board during the pool remodel since it's a basically an inevitable trip to the emergency room, just waiting to happen. As fun as it is, we've had some close calls with the kids over the years. Now that the pool is empty, anyone that walks on it isn't just risking falling in a nice pool of water, they're risking a nine foot swan- dive onto the concrete below. Now that's a trip to the emergency room.

Since we're currently enjoying the horrors of Arizona summertime heat,and there was absolutely no shade on the diving board area, I waited until after dinnertime to head outside as the sun started to dip towards the mountain. 

Not only was the diving board an injury magnet, it was in horrible shape. The base was a rusted eyesore. It sat on the section of deck where I had done my experiment in removing the horrible, slippery stone our predecessors had laid on top of the deck. 

It was really more of a problem with the nuts, seized onto the bolts protruding up from the concrete deck. There was a bunch debris around those nuts, concrete dust, pebbles, and rusty corrosion. A wire brush cleaned it up reasonably well so I could get a clean shot at the nut and bolt.

I tried, one last time, to macho-man those rusted nuts off with sheer brute force. No luck. The lower jaw of my crescent wrench actually flexed a bit and seemed like it was going to break. Looking at the photo, I realize my hand would have slammed into the base of the board if the wrench had broken. Gloves or not, that may have resulted in some broken fingers. You may argue with me, but I consider broken fingers undesirable. I'm kooky like that. 

Torch time! For this awkward location, I chose the Bernzomatic Trigger Start Hose Torch. I could keep the gas bottle back from my work area and use the smaller torch head to reach into the space below the board and still see what I was doing. This particular torch also has the ability to use MAP-Pro gas in addition to normal propane.

MAP-Pro burns hotter, 3,730° F, over Propane's 3,600° F. Propane should do the trick, MAP-Pro will just do it faster. I like faster when I'm sweating out in the heat with a handheld flamethrower and there are frosty beverages to be had when the job is done.

Check out the cool holster. It even has a metal sleeve for a hot torch.

With some WD-40 residue still on the nut, I laid down some fire on it. I got it HOT, blasting flame and slowly moving it around for 30 seconds or so. The idea is that the metal expanding breaks down the corrosion. The heat draws the WD-40 into the threads, similar to the way solder gets sucked into a plumbing joint when a fitting is heated. 

I slipped a monkey wrench into a steel pipe (actually an electrical conduit bender handle), to make a "cheater bar" for leverage, and rocked the nut back and forth a bit before putting some muscle to it. It broke free fairly easily and began to unthread.

Done deal. The nut un-threaded easily once I got it going. The threaded stud didn't snap off with the herculanean force I applied using the cheater bar. 

The garage sale monkey wrench and the loosened nut, still warm.

I continued, using the same method for the other two nuts. It worked perfectly. Check out the clean threads on the left bolt below. I suspect with a little cleaning it could be re-used if I was simply replacing the board.

Free Tip of the Day: Don't touch!!!

With all three nuts off, the board popped up easily. 

I guess it's something you never think about in the course of a normal day, but if you ever wondered, I can assure you first hand that a diving board is heavier than it looks. As the sun slipped behind the mountain, I lugged the beast all the way to the front curb to throw it on the quarterly bulk trash pile...

...and lugged it all the way back, when I realized the city had already cleared the pile. I guess I'll have the pool demo contractor dispose of it or for the next bulk pickup.

This torch technique is definitely going in my DIY playbook. I'm also looking forward to more projects using the flexibility of the hose torch.

Frosty beverage time!
