Church Work Day

I wrote a couple months ago about the renovation I oversaw of the house on the church property. The final step in that project was fixing up the landscaping, but we wanted to wait for nicer weather. The big day arrived a couple weeks ago and Tim had a great plan laid out for us and a bunch of nice plants picked out. The main projects were taking down two small trees, removing a bunch of bushes, taking out a huge out-of-control rhododendron, and moving a LOT of rock from the planter area to the church driveway. We rented a Dingo to help move all the rock and rip out the stumps and that ended up being the best decision of the day. There’s no way the work would have been finished with out it! I posted a bunch of photos at the end of this Facebook photo album but here is a before and after photo that shows part of the area we worked on.

Home Safety

At our last homeowner’s association, a Woodinville police offer was a guest speaker. She talked about the types of calls that came from our area (there aren’t many), and the size of the Woodinville police force (only 1 or 2 officers on patrol at any given time.) At the end of the talk, she offered to come by our houses and talk about security. Most people seemed to ignore this line, but I got her card and a few days later, we set up a meeting.

When she got to the door, she said, “I’ve been in this house before.” “I hope it was for something good!” “Oh yes, the original owners were the neighborhood watch captains.” Phew!

She walked around inside and outside and gave me some tips. Overall she said we were doing really well. Obviously I’m not going into detail about what she suggested we improve, but here are some general things she talked about that she sees:

  • Don’t put big bushes in front of your windows. This gives burglers a place to hide while they peek in. Keep them trimmed down below the bottom of the windows and the bottom of the bush should be 1-2 feet off the ground.
  • Make sure all your windows are locked or have dowels in the track to avoid them being forced open.
  • Where can someone hide outside your front door? You want to be safe if you step outside at night.
  • Which entries are the least visible from the street and your neighbor’s houses? Those are the most enticing.
  • What electronics can you see if you look in from the windows?
  • What kinds of friends do your kids have? Kids talk and if you have cool stuff in your house and an easy way to break in, word is going to get around.

I’ve made it a point to get to know as many of my neighbors as possible so hopefully they’ll notice if anything odd is going on. While there’s not any special history of burglaries in this area, there’s no reason not to take some simple precautions. A lot of this is common sense, but the trick is to make your house harder to break into than your neighbors’.

Rubber Meets The Road

If you don’t think that your physics classes were very interesting, hop on a motorcycle and whip through a corner or two. You’ll probably start thinking about those few square inches of rubber that are touching the pavement and somehow holding you in place. How does that really work?

Most of this post is a summary of a longer article so please head there if you want the full story. There are a lot of other good motorcycle physics discussions there too. The basic idea is that there are two laws of friction:

  1. Friction increases as weight increases.
  2. Friction is independent of the contact area.

The first one makes sense, but the second one probably sounds a bit odd. It states that if you set a brick on it’s end or on it’s side, it will start sliding at exactly the same angle either way. It might sound crazy, but it’s true.

So let’s apply this to a motorcycle. The first law states that when you brake you have more traction on the front tire because the weight is transferred to that tire. The second law says that when you corner, you have the same amount traction than you did standing up straight because you have the same weight of the bike pushing down into the pavement. (The force imparted from going around a corner is parallel to the ground so that doesn’t give you additional friction.) However, while you may have the same amount of total traction in a corner, you’re also using up more of your available traction to go around the corner. You can’t grab a handful of brake and expect good things to happen.

The second law always means that the size of the tire makes no difference in the amount of traction you have. In theory, if you built a bicycle tire and a motorcycle tire out of the same rubber compound, they would provide you with the exact same amount of traction. So why are motorcycle tires fatter? You get better handling characteristics from having a tire with a bigger curve on it. You don’t go from tread to sidewall as quickly when you lean over as you would with a bike. Also, most motorcycle tires have a tougher rubber compound in the middle for long tire life and a software compound on the sides for more grip.

Physics isn’t just a good idea, it’s the law!

DIY Irrigation

At some point we are planning to put in a proper irrigation system, but I think the backyard remodel is a couple years out. Since I’ve been spending so much time learning about caring for a yard, I don’t want to let it die off during the summer months when we don’t get any rain. But I also don’t want to have to move sprinklers around the yard by hand and have hoses laying in the grass. By pulling up an aerial view of my property from King County, I realized that with three sprinklers, I could cover most of the front and side yard.

I picked up three Melnor spike sprinklers, a 100 foot 8 ply 3/4” hose, and some female and male hose repair ends. (On a side note, I’ve been so impressed with that brand of hose that I have picked up two more of them.) I took the brand new 100 foot hose and cut it into three sections to run from the spigot too the sprinkler and then on to each other sprinkler. The hose repair kit gave me new ends for the hose and that all works very well without leaks. Tim had given me a hose timer so once I get into regular watering mode, that will come in handy.

This setup fulfills my requirements of not having to move sprinklers around and I can leave it set up semi-permanently. The downside is that since each sprinkler is covering a different span, the yard isn’t watered evenly. Also, when we had a plumber add a pressure regulator valve to help with the water hammer in the house, he turned down our water pressure to 40psi. Now that I’ve installed arrestors on every termination point in the house, I was able to crank that up to 50psi. 40 wasn’t enough to power all three sprinklers but 50 is just enough.

I also added some Y valves to the middle sprinkler which allows me to selectively shut off sprinklers down the line. This will come in handy when I need to water that big first section a little longer, and it was also helpful for tweaking the water flow to each sprinkler.

It takes me about 75 minutes to put down 1/2” of water in the big section on the east of the house. (An easy way to measure it is to set a used tuna can out in the yard while you run the sprinklers.) Once we get into summer I’ll set it so that it puts down 1/2” twice a week. For now we’re getting a few tenths a week spread out over many days. I’ll supplement the rain with a deep watering every once in a while.

Hopefully this work will leave us with the nicest yard on the block!

Cruiser vs. Crotch Rocket

There have been a lot of conversations directed at me lately implying that my choice of motorcycle was ridiculous. This comes mostly from pure sport bike riders claiming that my bike is “slow.” However, a couple of the questions have been honest questions from new riders so I’ll give a little spiel about why I love my bike in hopes that it will help some of you decide what you want to buy.

There are two basic styles of motorcycles for the road: cruisers and sport bikes. On a cruiser you sit straight up with your legs out in front. Think of a Harley. On a sport bike the handlebars are very low requiring you to lean forward and tuck your legs up under you. This is what you see people racing on TV.

Cruisers are great for long rides. They’re very comfortable and while you’ll get sore, you could put in a 500 mile day and still be able to move the next day. Sport bikes are built for speed and they can be quite a bit faster than cruisers. Generally, the faster your sport bike is, the shorter the distance you can ride before you turn into a giant cramp. You might think twice about 100 miles on a sport bike, but you’ll experience more thrills in those 100 miles than you would on a cruiser.

Now of course I’m generalizing and it all depends on the specific bike. MattM has a bike that would fall in the sport bike category but he puts in way more miles than I ever have on any of my bikes. But in general, I think the above paragraph holds up.

My bike, a 2009 Kawasaki Concours 14 ABS, falls into a tiny category called “sport touring.” Actually Kawasaki calls it “super sport touring” to reflect it’s race bred ancestors. It’s more of a niche market but it attempts to combine the performance of a sport bike with the comfort of a cruiser. Of course you can’t get the best of both worlds, but this bike comes pretty close. It has gobs more speed than you can ever pretend to use on a street (0-100mph in 4.7seconds?!?), but the seating position is much more upright giving you the ability to ride a lot farther each day.

It’s probably not a great category for your first bike since these bikes tend to be pretty heavy and they have huge engines that can get you in a lot of trouble. But if you like taking overnight trips but you want a little pep in your step, it’s a great style!

What’s next for me? Of course I dream about that a lot. I think I’ll have this for many years down the road, but when it does come time to sell it, I think I’d strongly consider going full “old man” bike. After I’ve hit 300-400 miles in a day, I really envy those guys on Goldwings with arm and backrests!

Your Mileage May Vary

If you’ve used a GPS in your car, you may have noticed that it doesn’t match your speedometer and odometer. Just about every car on the market has about a 3% difference between your actual speed and the displayed speed. (You’re really going slower than you think.) Imagine the lawsuits if people were getting pulled over because their speedometer reported that they were going slower than they really were. The difference can vary by car, tire size, etc.

Since getting the latest set of tires on my motorcycle, I noticed that my speedometer was getting pretty far off. It’s annoying to do math just to figure out how fast I’m really going. An actual speed of 60mph was reported as something more like 63-64mph. It also means that you’re racking up the miles faster which devalues your vehicle quicker than it should.

Enter the Speedohealer. They make a little box that connects in between your speed sensor and the dash. (Vist the HealTech web site to find the correct wiring harness for your bike.) You tell it exactly how much your gauges are off and it will make sure your gauges read correctly. I did a couple tests on the interstate with a GPS measuring my actual speed until I got it dialed in correctly. The unit also comes with a little button that you can mount somewhere near your dash that will recall your max speed and display it on the speedometer.

Installation on my 2009 Concours wasn’t just plug and play. When the unit was connected, the bike got a little hitch in it’s giddy up at low speeds. The instructions with the unit (specific for my bike) said that I needed to send the unaltered speed signal straight to the ECU. That meant cutting one wire from the main wiring harness and splicing in another one. I had to make the cut right by the plug going into the ECU, so if I did something wrong, it would have been very difficult to repair. I finally took the plunge and made the snip with visions of a four digit repair bill if I screwed it up. Thankfully all went well.

I hesitated to post this because I wasn’t sure how legal it was to monkey with your odometer, but I couldn’t find anything that said it was illegal to calibrate it correctly. Either way, I’m happy to be able to tell how fast I’m really going and have my odometer read the correct mileage. I don’t usually carry a mapping GPS on the bike so when I need to make a turn in 17.4 miles, I’ll actually be able to find it now!

Lake Chelan

On Memorial Day weekend, Tyla and I headed over to Lake Chelan State Park with her family. It’s on the east side of the mountains, so if you remember your Washington geography, you’ll know that it’s in the desert.

The park is more focused on day use than overnight camping, but we probably had the best trailer camping spot in the park. We bordered the woods on one side so we had some privacy. And even better, there was a small stream running in the woods behind the site that the guys named Pee Creek.

The park does have some incredible tent sites. Each site has room for one car to park along the road and then you carry your gear about 50 feet down to the water. Your tent gets set up on the banks of the lake. There’s no immediate water access since there are about 10-15 feet of huge rocks heading down to the lake, but it’s still a great view. If you have a boat, you can even rent a dock right by your campsite!

The lake itself is gorgeous. It’s 55 miles long and is the largest natural lake in the state. At 1486 feet deep, it’s the third deepest lake in the US and the 25th deepest lake in the world. The bottom of the lake is 388 feet below sea level! I couldn’t find any stats about the cleanliness of the water but it was amazing how far down you could see.

We had beautiful weather all weekend which let us enjoy a lot of time playing with Oskar down by the lake, go for a couple short hikes, and check out the small dam just down stream from the lake.

It’s a very popular destination which means there can be big crowds, but since it’s such a big lake, the boat traffic didn’t look too crowded. When I make my millions, it will be tempting to buy a house somewhere on the lake. Maybe this one will still be for sale.

In a three hour drive home, we went from desert lake to snowy mountain pass to wet coastal region. I love the Pacific Northwest!

Michelin Pilot Road 3

The front tire on my 2009 Kawasaki Concours has been wearing out and after 9700 miles, I no longer had much confidence in it. The back tire still looked pretty good, but I shopped around and decided to pull the trigger on new tires. The tech at Waldron Kawasaki suggested that I take the old rear tire home as a spare in case something happens to this new one and I don’t feel like shelling out the money for another tire right away. 10,000 miles isn’t a lot, but it’s not too low for a sport bike or a “super sport touring” bike which is what the classification of this bike.

The Bridgestones that came with the bike weren’t great and the compound on the front tires for the 09 model is notorious for being too soft and wearing out quickly. I opted for the Michelin PR3’s after quite a bit of internet research and talking to the guys at the shop.

First of all, it looks visually like it might be some kind of rain tire. The tire is siped and can move a lot of water on wet days, but it’s still very durable for hard riding and will last a long time. When people see the tire, the general reaction is that there is too much tread and there can’t be enough grip. However, a UK magazine did a wet weather test and was able to lean the bike over in the rain and drag a knee. Another reviewer took them to the famous Spa race track, ran a bunch of laps, and then ran thousands of miles with them on normal roads. Not too shabby!

The tire is dual compound which means the middle is a harder compound for long life and the sides are softer for increased grip in the corners. Reviewers also say that this tire is incredibly quick to warm up and you get good grip almost as soon as you leave the driveway.

Since this is the first time I’ve ever purchased new tires for a motorcycle, I don’t claim to be any kind of expert, but it’s cool to see how much technology and progress there is in the tire world. I was surprised that I could feel a difference when I rolled out of the dealer, but I don’t know if that was just because the tires were a different shape. The old ones were squared off a bit. Whether I’ll be able to tell a difference beyond that or not, I hope these last me for another 10K miles and beyond!

Beware Of Bikers

It’s been almost four years since I wrote a post called “What Motorcyclists Wish You Knew.” While I still wish that every driver would read that post, I realize that there are always going to be bad drivers out there and it’s up to me to stay safe. I’ve been riding for seven years now and I feel like I’ve developed a sixth sense about traffic situations. 99% of people on the road follow a bunch of undefined social norms. The trick is to look for any car that is straying even slightly from the norm. It’s easy to spot the guy flying up behind you and weaving in and out of traffic erratically, but what about that car about a quarter mile up who keeps drifting slightly out of their lane or the person in the lane next to you who keeps slowing down to 50 before speeding back up to the speed limit. Those people seem more dangerous to me because they’re probably on their phones and are very unaware of what’s going on around them.

But if I could boil down that previous post to one item and share it with everyone, it would be “don’t ever enter a lane in front of a motorcycle.” That means don’t merge in front of a motorcycle on a highway or pull out in front of a motorcycle from a side street. It’s really hard to judge the speed of a motorcycle with a quick glance since the size is so different. Now if you turn on your blinker, wait for the biker to acknowledge you and wave you over, by all means go for it. But squeezing into that little space like you would between two cars is just not smart.

And while we’re at it, this applies to trucks too. I spent a lot of time on 405 in stop and go traffic and it blows my mind how many people will use the space in front of a semi to change lanes, even when traffic is coming to a halt. Why do you think that big space is there in front of the 30 ton behemoth? I’ll give you a hint: it’s not for you to cut into.

So be safe out there this summer! Pay extra attention to motorcycles around you and give them a little extra room. Yes, some riders are jerks, but the vast majority of us are just out to have a little extra fun on our commute. I’ll leave you with one little story from a ride a couple years ago. I was stopped in a line of traffic when a lady came whipping up the side and tried to cut into the spot that I was occupying. Thankfully she slammed on the brakes in time but she ended up close enough that I gave her a solid pound on her window with my fist. She rolled it down and started yelling at me. I waited for her to finish, flipped open my visor and said, “After you took this spot, were you planning on calling my wife to tell her why I won’t be home for dinner?”

Drills

When I moved out on my own, my parents got me a 9V cordless Makita drill. It served me well through a ton of projects, but after 10 years, the batteries are worn out. It was either buy some new batteries or upgrade. After looking at the prices, I went with the latter and decided to keep the old drill around for smaller projects around the house.

I’ve loved using Tim’s 18V DeWalt drills. He works them much harder than I will and they’ve held up well, so that, combined with some online reviews, convinced me to stick with that brand.

DeWalt recently made a huge switch and broke backwards compatibility with their batteries. With over 60 million batteries on the market, that was a pretty big decision. I decided to buy into their new battery technology. It’s denoted on the market right now as 20v. Technically it’s actually still 18v but people were getting confused so it’s a marketing gimmick. The new batteries are lithium-ion and have a much different form factor that allows for smaller handles.

I ended up with the DCK280C2 combo kit which includes a compact drill, impact driver, two batteries, charger and a hard side case. Tim’s XRP batteries will last longer than mine, but I have the option of getting some “MAX Li-Ion 3.0Ah” batteries if I want. I’m very happy with the 1.5Ah batteries that were included though. On the recent deck project, I put in 250 screws with the impact driver before the first battery gave out. Each screw was going through 5/4” cedar into pressure treated support joists. Not bad! Each drill has built in lights that stay on 20 seconds after you’ve let off the trigger and that comes in pretty handy in dark spots. The lights on the impact driver work a little better because they have three lights around the chuck instead of a single light under the chuck.

Maybe impact drivers are old news, but I’ve only started using them in the last year or so. If you’ve never tried one, give it a shot next time you’re at Home Depot and you see the little demo setup. They are incredible. You’ll twist your mind trying to figure out how you can drive a screw all the way through a stud without exerting any pressure on the drill. It’s like a knife through butter!
