A drill-down on making great holes

One thing penetrating into another is always made easier by first creating a hole.

No matter how skilled, how mighty, or how overwhelmingly powerful the athlete carrying the ball is in the sport of professional football, his success in progressing past the line of scrimmage will correlate directly with the size of the hole created.

If the 300-pound offensive lineman creating this hole was successful in separating the angry bunch of 300-pound defensive linemen in the way, then the skilled ball carrier passes through with minimal discomfort.

If the offensive lineman fails to create a hole, either due to lack of skill, poor timing, or the fact a few individuals are somewhat disgruntled by recent contract negotiations, then the ball carrier will certainly be facing a whole lot of hurt.

Most nails and screws will penetrate wood. There are self-tapping screws designed to drill and pierce through steel. There are even nails that can be hammered into solid concrete.

However, it’s always easier when there’s a hole created first.

Let’s look at some of the things we can use to create holes. Things to realize; steel drill bits will cut through wood, but wood bits won’t cut through steel, while concrete bits will only really cut through concrete.

That being said, with enough weight or pressure, a drill bit could be forced through just about anything, just like a grand piano could be forced through the mail slot of a front door, but it wouldn’t be pretty.

To keep things easy, and pretty, we use the proper designated drill bit for the task at hand.

Essentially, small holes of 3/16” or less, often used to pre-drill wood in order to accept a nail or screw, are effectively done with a steel drilling bit.

Holes required to be anywhere from a quarter-inch to 1.5 inches in diameter are best drilled with a spade bit, which has a flat head, similar to a canoe paddle. Using a steel bit for these sized holes will work, but you’ll be forfeiting accuracy. A steel bit will move around a little on the surface before it bites down into the wood. Plus, the hole will be frayed at the sides, due to the steel bit lacking the extended, cutting edges found on a typical spade bit.

Anything larger than 1.5 inches would require a hole-saw, which is a cylinder-shaped cutting tool. Hole-saws are two component drilling tools, requiring a centre bit, referred to as a “mandrel,” to start the hole. The mandrel further guides the circular hole-saw into the wood. If this is your first hole-saw purchase, don’t forget to buy both components. Generally, one mandrel will service a number of various hole-saw diameters.

However, not all centering mandrels match all hole-saws. So, be sure to test-fit your existing mandrel with the newer hole-saw before leaving the building supply centre.

Note to self: drilling with larger spade bits and any sized hole-saw bit is like playing catch with a football, best done using two hands. If your drill doesn’t have an extended arm to place a second, steadying hand, definitely consider ordering one of these components for your specific brand of drill. Otherwise, keep two hands firmly on the trigger shaft.

Spade bits and hole-saws will sometimes jamb in the wood. If that happens, and you’ve only got one hand on the drill, the sudden twist is going to leave your wrist looking and feeling like a strand of cooked spaghetti.

Next, be wary of purchasing just any spade bit. Some spade bits have regular tips, others a full-thread tip. The full-thread bit option effectively draws the spade bit blades into the wood, making this bit very aggressive— which is fine if you’re an electrician with 1,000 holes to drill. Otherwise, I prefer the gentle push, draw back (which helps clear the hole of cuttings) then push forward strategy of a regular spade bit.

Next week we’ll have more on creating holes.

Good building.

Painting’s more than picking up a brush

Painting tradespersons don’t get the respect they deserve.

This is due to the belief most of us feel we’re generally capable of painting a room with little consequence, while delivering acceptable results.

True enough, few people have electrocuted themselves or flooded the home’s basement as a result of performing a poor paint job. Plus, cuts and bruises are minimal, and although painters tend to keep their fingers over the course of their career, there was the tragic beheading of Sir Edward “Eggshell” Egleton, by order of the Earl of Warwick in 1645, due to a sloppy effort of painting where the ceiling met the stained crown trim, a treasured molding of the Earl. Unfortunately for Eggshell Egleton, who prided himself on a revolutionary paint texture that duplicated a beloved breakfast food, but whose trimming hand was a little shaky, masking tape would only be invented 300 years later, and painter’s tape, another 50 years after that.

All to say, dipping a brush into a can of paint is relatively easy.

The key to getting from this point to a desirable finish, while avoiding any headaches, will take a whole lot of care.

First, organize your supplies. Besides the paint, angled brushes, pans, roller cages, and refills, you’ll need a few canvas drop mats, drywall repair compound, painter’s tape, and paintable caulking.

The key to achieving a nice finish is to first prepare the surface. No matter how good the paint, it won’t camouflage nail holes, dents, or smooth out a poor drywall repair job.

If your goal is to paint the room in one day, pick up a bag of ‘sheetrock 20.’ This powdered, just add water compound can be sanded 20 minutes after it’s applied.  If time is on your side, regular joint compound will require 24 hours to set.

First, clear the room of as many obstacles as you can. Although you’ll be using a water-based paint, removing paint splatter off the kitchen table or the coffee maker will be a pain in the butt, especially if the droplets go unnoticed for a few hours.

Using a narrow putty knife, and a small plastic container you’ve salvaged from the recycle box, mix a small amount of sheetrock 20 to a cake icing consistency. Then, apply it over the holes and rough surfaces.

Next, start taping. Professional painters avoid taping because it’s time consuming, costly, and because they’ve in most cases mastered the technique of trimming. Unless you’re a medical surgeon or dismantle bombs for a living, odds are that with the amount of coffee and medication in your system, your hand stroke is about as steady as gas prices on a holiday weekend.

So, protect the things you don’t want to colour with a painter’s tape, and not masking tape. Painter’s tape is a new-and-improved version of masking tape, and is designed to seal as soon as paint makes contact with its edge.

Besides your crown, window, and door moldings, be sure to tape around the doorknobs and light fixture bases as well. Once you’ve finished applying the painter’s tape, the ‘sheetrock 20’ will be ready for sanding.

Next, lay your canvas drop mats in position. The canvas mats are more expensive than the plastic or paper protective coverings, but they spread and handle far better. The canvas mats are available in 3’x20’ or 4’x12’ formats, which is convenient when moving from wall to wall.

Try not to walk on the mats as you paint. Otherwise the droplets they’ve absorbed will end up on the soles of your slippers, with your trips back and forth from the fridge well documented from that point on.

Even though you’ve protected things with a painter’s tape, begin the painting sequence using a quality tapered brush around the moldings and where the wall meets the ceiling. Once the molding’s been painted, remove the tape as soon as you can. This way, any paint that’s made its way under the tape can be easily rubbed off.

Good painting.

The cutting edge

Using the right type of blade for the job is important. Postmedia Network

“That’s not a knife . . .this is a knife,” states Paul Hogan (starring as Crocodile Dundee) as he presents his 10-inch Bowie survival knife to a group of street hoodlums, and “We’re gonna need a bigger boat” as stated by Roy Scheider (starring as Chief Brody) to boat Captain Quint, as Brody backs into the cabin area in a somewhat bewildered manner, are a couple of memorable movie lines that exemplify persons showing up for a job with slightly less than adequate tools for the task.

One situation has a New York gangbanger looking to challenge a seasoned Australian outbacker with a simple six-inch switchblade, with the other having a mish mash crew looking to catch a 25 foot Great White shark while aboard the Orca, a 30 ft. aged wooden trawler.

So, with today’s theme relating to cutting and munching, we’re going to be looking at what type of blades are best suited to cut the various building products we do-it-yourselfers will be encountering over our amateur careers.

First rule of thumb to make note of? If there exists a building product or piece of material that needs cutting, then there also exists a specific cutting blade or wheel for that task. That being said, can some saw blades or knives serve in a multi-purpose role, having the capacity to cut or sever a number of building products other than then the one they’ve been specifically designed for? Absolutely.

A circular saw blade, or hacksaw blade formulated to cut steel, will eventually make its way through a piece of wood, eventually, just like Frank Morris eventually carved his way out of the Alcatraz prison in 1962 using a cafeteria spoon. Had inmate Morris had the luxury of procuring himself a cordless drill, with the appropriate concrete bit, I’m sure he would have jumped on the opportunity to save himself the six months of work. And, this is an important point for do-it-yourselfers to understand — don’t go for the spoon, or otherwise semi-adaptable saw blade or drill bit in the toolbox simply because it could perform the task at hand, although poorly, but save you the 10 minute drive to the local building supply center.

Using an 80 tooth finishing blade to rip lumber (cutting lengthwise), when a 24 tooth blade is the better choice, will actually cost you time. Furthermore, a finishing blade designed for cross cutting, but instead used in a ripping manner, will overheat, most likely warp, and certainly dullen the teeth beyond any further productive use. Then there’s the risk factor of forcing lumber into a finishing blade that was not meant to chew through wood at a rip pace. You know you’re tempting fate when pushing a piece of lumber through your table saw requires the same amount of force used to push an automobile out of the snow. In this scenario, the blade is heating up, and is moments away from swelling or warping slightly. When this happens, the blade jams itself into the plank, either shorting out the table saw, or as in most cases, causes a ‘kick back’, appropriately referred to as such due to the lumber jolting backwards, usually hitting the operator in the groin with a force equal to that of an annoyed Appaloosa.

Essentially, every circular or table saw blade will list the items it’s designed to cut on the blade itself. So, if you’re cutting melamine, or plywood, or ripping lumber, look for a blade that lists exactly the type of cutting you’ll be performing. Looking to cut re-bar, steel bolts, angle iron, or steel lath, then choose the appropriate metal blade. Avoid the grinder type of composite discs to cut steel or concrete. They’re certainly less expensive, but wear down quickly. A proper steel blade, designed for the cutting of steel, concrete, or non-ferrous metals (metals that don’t contain iron, such as copper or aluminum) is your best bet.

As always, wear tight fitting work gloves and eyewear when cutting anything.

Good building.
