Building A Swing Bed For My Wife

Project:
Building a Swing Bed for my wife's Backyard Sun Shade Pergola

Difficulty Level (Easy, Medium, Hard, Insane):
Medium

Process:
This one was actually a bit tricky for two reasons:

1. I wanted the swinging mechanism to be nice, smooth and quiet
2. I wanted to be able to turn the swing bed into a regular width swing

I decided to accomplish #1 by not using chains but to use bearings instead. Except for it took a little "Eigenheering" (as a friend of mine calls it) to get the support brackets just right. I could have just bought the ready-made bearing supports from Princess Auto but I didn't want to spend $120 on that alone so instead I bought 8 bearings for a couple bucks each and another $10 bucks worth of iron. And, now I can support at least 1200 pounds on those supports...

The bed frame was definitely a bit tricky because I'm chopping out a square piece in the middle essentially leaving two corners unsupported. So I had to do some doubling up of the 2x4's to make it strong enough.

The last thing I had to do is fit some cross-braces in the roof beams and cut 4 holes through the shade cloth (after I sewed a circle around the hole to prevent from tearing)

Now it's being used a lot and it definitely scored me some brownie points with my wife!

Fixing The Car Horn For Our PT Cruiser

Project:
Fixing the car horn on our PT Cruiser so it will pass inspection

Difficulty Level (Easy, Medium, Hard, Insane):
Easy

Process:
This little car has been amazing when it comes to reliability and reparis but I still actually hate it quite a bit. My wife loves it though and that's why we're keeping it.

In any case, the yearly inspection passed except for the horn which isn't working so I had one night to fix it. I figured it would be the little switches under the car horn because over the last year it has started to slowly go and become more intermittent until a few weeks ago when it completely gave out.

The first thing I had to do was disconnect the battery, take off the steering wheel air bag, then take out the horn switches. After some usage it looks like the horn buttons weren't making proper contact so I used a screwdriver to bend the contacts up a bit and re-installed the buttons (there were 4).

Unfortunately, it still didn't work, so I had to use my multi meter tool to trace the contacts. What I found was that there was a plug underneath the steering wheel that somehow didn't make proper contact so I had to bend those contacts with a little screw driver and then the multi meter showed proper continuity.

Unfortunately, that STILL didn't work, so off the front left wheel came (as per my repair manual's instructions) but I could not for the life of me find that stupid horn. Just out of curiosity I checked the other side of the vehicle and wouldn't you know it, there it was! No idea why they installed the horn on the right side instead of the left side.

Oh well! I stuck the multi meter into the two little plugs and had my son make contact by the horn buttons and the voltage promptly went up to 12V from 0. Great. Except, the horn still didn't work so I took it off and hooked it up directly to the battery and voila! It worked. What the heck? After I had a closer look at the contacts I saw that it was rather tarnished from general corrosion so after cleaning the plugs and all contacts IT WORKED!

After re-installing everything and driving around the block honking my horn (my neighbors were probably wondering what was going on) I parked the car in the garage.

The next day I drove by the shop where they inspected the horn and gave my sticker. Good for another year!

As a funny thing is that after work when I tried the horn again it stopped working again. Looks like I'm gonna have to do a little more cleaning and maybe I'll put some NOALOX on it...no rush though this time.

Creating A Replacement Cap For Our Pool

Project:
Making a little plastic cap to keep the air in our small paddling pool

Difficulty Level (Easy, Medium, Hard, Insane):
Easy

Process:
It was July 1st and almost warm enough to put out the little paddling pool for the kids so I hauled out the air pump and got going just to realize that one of the 3 plugs that keeps the air in for the pool wall was missing. I tried a regular pop can cap but it was too big and no other bottle had a cap that was just the right size.

I realized I could probably just go to walmart and buy one for a couple of bucks but where would be the fun in that? So I hauled out the alginate and the two-component urethane casting resin (both from www.smooth-on.com) that I bought a couple of years ago after the Fix that wasn't fiasco.

The first step was to create a negative mold of the bottle cap using the alginate. Then, I had to mix the two components of the rubber and pour it into the cavity. An hour later it was de-mold time, clean up the edges and cap the pool

Tools:

Materials:
2 tbsp Alja-Safe Alginate
1/8 cup Smooth-Cast 380
Some tuck tape

Cost:

1hr

Savings:
$2.50

Works great. The air is holding.
