The Virtual House


This video is a combines several of my favorite technologies. In summary:
  • A hand held GPS was used to record coordinates and elevation points for the land.
  • A 3D interpolation algorithm was created to translate the GPS data into a DEM (Digital Elevation Model).
  • The DEM was imported, and the house drawn, using Google SketchUp.
SketchUp is my new favorite desktop application, moving Visio into second place...

More to come on these topics.

The Vegetable Patch

Having a vegetable garden is a must, so once the weather started to warm up, we began planning. Because the ground is largely clay and rock, we knew it was going to require some work. We chose a location on the north side of the house that is in sun for most of the day and decided to build raised beds that we could fill with compost and top soil.

After settling on a basic design, the real work started! When Dan began digging in the site, we discovered that there were many more rocks and much larger rocks than we had anticipated. It quickly became clear that additional equipment was needed, and so we bought a pick-ax.

Dan smashed the biggest rocks with the pick-ax and dug out enough dirt to set the raised bed into the hillside. He then built a sieve using our garden fencing materials so that we could sift out the smaller rocks and debris. Note the large stack of rocks to the left of the garden. That pile continues to grow and may turn into its own little rock garden.

We were also in need of a permanent compost site. We used re-purposed wood pallets to form the frame of the three-sided compost. If you have the space, this is a cheap and easy way to set up a composting site. Start adding leaves, vegetable waste from cooking, coffee grounds, tea bags and you will have fresh, rich soil in no time.

Once the first raised bed was done, it was time to put the fence up (to keep out pesky animals) and to begin work on the second bed. We had originally planned on only building one bed, but decided it would be more efficient to build them both now - plus we knew we would want the extra growing space!

In this shot, taken just before we started planting seeds, you can see that both raised beds have been installed and top soil, compost, and peat moss have been added to create a rich growing environment. At this point, we also had two compost sites and the fence was nearing completion.

By the end of May, our vegetable patch was complete and seeds had sprouted! We are looking forward to fresh tomatoes, zucchini, green beans, peas, carrots, basil, pumpkin, and peppers!

The Driveway Project - Part 1

On moving into our new house we knew that the driveway needed to be paved. I heard from the builder that he'd left it ready for paving when he'd finished it several years ago, but it was never completed. As anyone who's seen it recently knows, it has significantly deteriorated since then. The problem is mostly due to the steepness of the drive, the amount of water that is diverted onto it, and the fine gravel base. You see, the house sits on top of a hill, and the driveway is about 500 feet (150 meters) long. When we get lots of rain the velocity of water running down the slope likes to take the gravel with it. This results in huge 1 foot deep gouges/channels/ruts in places where the water has eroded deep into the ground. Needless to say, the Driveway Project was initiated.

The Paving Project started by getting estimates from several paving companies. I arranged to meet with each one, so that we could discuss my concerns about the drainage. The concern is about where all the water will go. Erosion along the edge of a driveway can cause it to crack and crumble away. Several options where suggested along with difference widths, depths of asphalt, etc. These options included curbing, grading, drainage ditches, dry-wells and more. At this point we also consulted with a Civil Engineer and the Town Engineer. Apparently where we live there is a zero additional watershed policy, which means you're not allowed to direct water off your property onto the public roads etc. without permission. At this point I was beginning to wonder if we where over-thinking it a bit.

Eventually I selected a paving company and scheduled them to do the work at the start of June. They'd said it would take 2-3 days, so I presumed that if they started on a Wednesday, they would be finished by the weekend. Things seemed to be going well when they started the preparation work on Tuesday, a day early. They brought in several truck loads of stone "process" material to level and grade the base. We had a rain on Wednesday, but by the end of Thursday, the base looked like it was coming to completion.

Two weeks passed without the paving company doing any more work. Apparently they wanted to let the base "settle" before continuing work on the driveway. That makes sense and in the days after the work they did, we did notice several soft spots appear. Unfortunately we've also had some of that rain I mentioned a few paragraphs prior, and now yet again there are several good sized ruts running down it. Not as bad as before, but never-the-less, not ready for asphalt.

The paving company are due to return tomorrow, so we'll see what happens next...

Consumed by Sim City

After finding a link to SimCity Classic, I was consumed once again - for a couple of weekends, at least. Be warned: it's addictive.

Tractor Repair

Last weekend I started cutting the grass on my relatively new tractor. On the first pass down the edge I was abruptly stopped by loud metallic banging as the blades came into contact with something other than grass. In the panic of the moment, I edged forward. The bangs stopped, but the blades no longer had the normal spinning sound that I'd come to expect. On looking down, I noticed that one of the blade shafts was out of alignment, so unhappily, the tractor and I retreated back to the garage.

On further inspection and after a flurry of tool-box activity, it appeared that a mower blade had hit a piece of steel rod that was poking out of the ground. Not only had it taken some good sized chunks out of the blade, but it had also broken (as in completely severed) the mandrel housing (for the blade shaft) away from the 4 mounting bolts.

I don't like things to be broken, it's an annoyance to say the least. I quickly pulled out the parts manual on got on the web-site to determine the replacement parts that were needed. It turned out that the mandrel bearing (15) and shaft bearing (13) where good, so I only needed to replace the mandrel housing (14). However, when the mandrel broke, the pulley (32) was pulled in by the tension in the deck drive belt, which also tore up the belt somewhat, so to be on the safe-side, I ordered one of those too.


After the order was placed, Erin and I went out with pick-axe and hack-saw in hand to remove the offending piece of metal rod:

The expedited order was placed on Sunday, the parts arrived on Tuesday afternoon, and I was back on my tractor in the evening.

First Flowers!

One of my first projects this spring was to clean up the flower bed along the front of the house. The area was completely overgrown, so I pulled up the grass and weeds and cleared out hundreds of rocks (literally!). Because the soil around here is a lovely mixture of rocks and clay, I added some fresh compost and top soil into the mix and crossed my fingers that everything would grow!

After clearing out the bed, I transplanted our collection of Asiatic Lilies from the old house to the new house. I was surprised at how big the lilies already were in early April when I dug them up, but the process of moving the bulbs went surprisingly well.

With the lilies happily transplanted, it was time to finish planting. For this year, we decided to keep it simple by adding a row of daylilies (Happy Returns and Red Volunteers) interspersed with zinnias. Once those were in, we added a layer of fresh mulch and voila!

All the plants have been thriving in their new home and just this week the first flowers began to appear! Plans are already in the works to add new flower beds next year.....

Choosing A Tractor

Ever since my recent "tractor" purchase, I've been turning into a tractor-nut. When I dive past the a works crew using their tractors to cut grass by the side of the road, I find myself craning my neck to get a better look....

Even before we moved into the new house, we knew we'd need a ride-on lawn-mower (or "tractor") to help manage almost an acre of grass lawn. With little experience in the field of ride-on mowers, I began doing some research. This was a time consuming process, during which the grass was slowly inching upwards.

I began by looking at what Lowes, Home Depot and Sears had to offer. I discovered that the Poulan and Craftsman (Sears) tractors are actually branded versions of the Husqvana tractors. I also looked at John Deere, but somehow missed Cub Cadet and others. I worked through various buying guides to try and determine which tractor was right for me. It was not an easy task with a hundred or so to choose from. To cut a long story short, I now know that there are several main features to consider when selecting a tractor:
  • Deck Size
  • Transmission Type
  • Engine Type and Horse Power
  • Supported Attachments
  • Wheel Size
Other factors to consider are:
  • How much grass will you be cutting?.
  • What kind of terrain will you be driving on?
  • What else might you like to use the tractor for?
  • Price.
Tractor selection is confused further by terminology such as "Lawn", "Garden" or "Yard" tractors. For example: on the sears website, Yard tractors are found in the Garden tractors section, and come with a manual that says it's a Lawn tractor and talking to the sales associates just adds to the confusion. One might think these terms can be used interchangeably. However, my research has lead me to be believe that Lawn, Garden, and Yard are categories referring to overall increasing "size" of the tractor. They become "Yard" tractors if they have 23 inch wheels or greater, and a Yard tractor is capable of accepting "ground engaging" attachments, such as a leveler or dozer blade, both of which require a "sleeve hitch" (different kind of hitch to regular attachments).

Anyway, after many hours trying to digest all this, I finally selected the Craftsman Lawn Tractor Model No. 917.288900. This particular tractor is also known as: DYS 4500, Mfr. model# 28890, and Sears item# 07128890000. It has a 48 inch deck, hydrostatic transmission, a 25HP Kohler twin V engine, accepts most non-ground engaging attachments, has 20 inch wheels, and a cup-holder.

In a future post, I'll tell you how I've been getting on with this little tractor.

Felling a Tree

During a break from the paving project (see previous post), we decided it might be fun to attempt some dead tree removal. Anticipating that we might need to deal with trees, one of our first purchases for the new house (bought before we even moved in) was a chainsaw. We have gotten good use out of the chainsaw so far – mostly using it to cut fallen logs into firewood-sized chunks – and have accumulated a nice stash of wood for next winter.

For this tree removal project, we decided to take on one of the dead trees that looked ready to topple over. Dan and James (Dan’s brother) first attempted to pull the tree down with a rope, but evidently the tree was sturdier than it looked, and unfortunately for Dan and James, the rope was not as sturdy as it looked. So with some advice from onlookers, Dan felled his first tree with the chainsaw.



The tree fell beautifully and couldn’t have landed in a better spot! The only downside was the amount of work it took to clean it up and cut the trunk into small enough pieces to move. We now have stacks of firewood and probably won’t be needing to fell anymore trees anytime soon.

The Paving Project

Last week we had visitors in town. My parents and brother where visiting from England to see the new house (and do some shopping). Knowing that they like to be kept busy, we'd put together a list of potential projects to work on during there stay.

The main project that was successfully completed was extending the patio path alongside the house to meet the new and soon-to-be installed driveway. Difficult weather conditions made it challenging with extremes of torrential rain and blazing sunshine. We began by splitting into two teams: one to excavate the work area, while the other sourced the paving stones. In this matter, team one made much better progress on day one.

Heavy rain over-night threatened to turn the paving project into the swimming-pool project, but after bailing out, and collecting half a pallet of stones, we were in good shape to make some progress. We then brought in extra gravel and the compactor (also-known-as "Whacker") to try and firm up the water-logged base. We also had to source extra stones for the edge due to extending the path past the edge of the house. By the fourth day we where on a tight schedule. Whacker had to be back by 3pm, so we really got down to business. An 8am start saw another round of "whacking", before we started to lay the stones.

Most of the stones went down quickly, helped by the fact that we laid out the pattern first. The edges and corners took slightly more effort (and not helped by the rising temperatures), but in the end it turned out very nicely.

Thanks to all who helped complete a successful project!

Welcome to our blog!

This is the place where you can get the scoop on the latest MacNick happenings. Here's a quick summary of the year-to-date:

Throughout January we spent a lot of time wondering if our house purchase was going to happen or not. It had been a lengthy process but we eventually got some good news and our closing date was set. February came and in a final hurdle we missed the scheduled closing date only to have it rescheduled 2 days later. Several months of anguish became worthwhile when we moved into the new place. We had a busy few weeks before our March vacation to Bonaire. April was a busy month with visits from friends and family in-between house and yard projects, and a tractor delivery. During May we made some difficult driveway decisions and booked a trip to Alaska. Now June is here and we're almost half way through the year...
