If you've ever seen all those intricate 3D wood reindeer or mentally stimulating games pieces and considered how they're produced, you're looking with the magic of scroll saw compound patterns . It's one associated with those techniques that will looks incredibly difficult to the uninitiated, but once you obtain the hang associated with it, it's effortlessly one of the particular most satisfying things you can do in a woodshop. Unlike standard smooth scrolling where you're just cutting away a silhouette, compound cutting involves functioning on two sides of a wood block to make a fully three-dimensional object.
It's a bit of a mind-bender the very first time you try this. You're essentially reducing a shape through the front, then rotating the wood 90 degrees plus cutting another shape from the aspect. When the discard pieces fall apart, you're left along with a finished 3D figure hidden within. It feels a bit like being a sculptor, only the saw does the particular heavy lifting regarding you.
Getting Your Workspace Ready
Before you jump into your first collection of scroll saw compound patterns , a person need to make sure your set up is actually able of handling the job. Most standard scroll saws can perform this, but the key may be the thickness of the wooden. Since you're slicing through a strong block—often 1. 5 to 2 inches thick—you need a saw that's squared up perfectly. In the event that your blade is usually even a small bit tilted, the particular front and back of your piece won't line up, and your 3D elephant might end up looking more such as a Picasso artwork than an animal.
Look at your table with a small square. It wants to be exactly 90 degrees to the particular blade. Also, create sure you've obtained a fresh cutter. For compound slicing, I reach for a #5 or even #7 reverse-tooth cutter. You need something beefy enough to clear the sawdust out of a deep cut without drifting or even bending under the particular pressure. If the blade is too slim, it'll wander within the wood, and your "3D" effect will be ruined before you even finish the first side.
Prepping the Wood and Patterns
The way a person apply scroll saw compound patterns is arguably the most important stage. You aren't just slapping an item of paper on the top of a panel. You're wrapping a pattern around a square block associated with wood. Most patterns come in two parts: a "front view" and a "side view. "
I've found that the particular best way to do this is to use a square block associated with wood—something like cherry, walnut, or actually a nice piece of clear pine. Make sure the block is completely square on all four sides. If it's even slightly away from, your patterns won't align.
A pro tip that'll save you a ton associated with frustration: cover the particular wood in blue painter's tape or clear packing record before you decide to glue the particular pattern down. This makes the document much easier to peel from the lime later, plus the packing recording actually lubricates the blade a little, which prevents the wooden from burning. As soon as the tape will be on, use a little bit of spray adhesive in order to stick the front side pattern on one particular side as well as the side pattern within the adjacent side. Ensure they're lined up in the base!
The Cutting Process: The particular "Aha" Moment
This is where the real fun starts. You start by cutting out the pattern upon the first part. Now, here's the key that catches every single beginner off safeguard: don't let the scrap pieces fall apart yet.
When you cut the first side, the particular pieces will desire to fall out. In case they do, you'll lose the flat work surface you need to cut the second aspect. It also means you've just cut away the pattern for the second side! To repair this, most scrollers use a little bit of clear tape to "stitch" the scrap parts back into place as they proceed. You want the stop to remain as the solid cube until the very final cut is produced.
Once the first side will be cut and taped back together, rotate the block ninety degrees and begin on the second pattern. This is the particular part that requires the bit of patience. You're cutting by means of the "ghost" of the first cut, so the opposition from the wood might feel a small different. Simply take this slow and the actual lines.
Whenever that final trim is finished, a person get the "big reveal. " A person pull the video tape off, the discard pieces fall away, and suddenly there's a 3D item sitting in the center of the particular mess. Honestly, I've been carrying this out for years, and that moment never gets old. It's such as a little hit of dopamine each time.
Finding the right Wood for the Job
Not really all wood is created equal when it comes to scroll saw compound patterns . If you're just starting out, stay away through the super hard stuff like oak or hickory. They're beautiful, sure, but they'll fight the cutting tool the whole way, plus you'll likely end up with burn marks that are usually a nightmare in order to sand off.
Basswood is a classic choice regarding beginners because it's soft and has a very tight materials, which means it won't splinter. However, when you want something which looks a little bit more "finished, " cherry and walnut are fantastic. They will cut cleanly plus smell great while you're working. Simply keep in brain that the wider the wood, the particular more heat the blade generates. If you see smoke, you're either pushing too much or your cutter is dull.
Common Pitfalls to consider
Let's discuss the stuff that will usually goes incorrect, since it happens in order to the best people. The biggest issue with scroll saw compound patterns is blade drift. Because you're slicing through such a thick piece of wooden, the bottom of the blade may not be perfectly aligned with the top. To describe it in triggered by either a dull blade or even a lot of "side stress. " You've got to allow the saw do the work. If you're pushing the wood to the blade, the cutter will flex, as well as your 3D shape will be distorted.
One more common headache will be pattern alignment. If your "front" pattern is a quarter-inch higher compared to your "side" design, the features of your carving won't meet on the corners. I usually pull a "reference line" across the corner from the block just before I stick the patterns on. If the lines upon the patterns match up that reference series, I know I'm good to go.
Finally, don't forget regarding the "internal" cuts. Some compound patterns require you to drill an opening and thread the particular blade to cut out a middle section. If a person have any of these, always do them first . It's easier to handle a solid stop than one that's already half-cut and held together by tape.
Finishing Your 3D Work of art
Once the particular piece is out there of the block, you're going to possess some sanding to do. There's no way around it. Compound cutting often leaves small "steps" or fuzzies where the two cuts met. A set associated with small needle documents or some folded-over sandpaper is going to be your best friends here.
Since these pieces are usually small and intricate, I prefer a simple "dunk" finish. A mixture of mineral oil plus beeswax works wonders. You simply dip the particular piece in, let the excess spill off, and wipe it down. It brings out the particular natural color associated with the wood without having the hassle of trying to clean lacquer into small 3D crevices.
Using scroll saw compound patterns is an amazing way to level up your woodworking sport. It takes you out of the 2D planet and lets a person create actual objects—toys, ornaments, chess sets—that people can pick up and look in from every position. It might take a couple associated with "practice" blocks (also known as firewood) to get the pressure and alignment best, but once a person do, the possibilities are just about endless. Grab a stop of wood, find a cool design, and give it an attempt. You may be surprised with what's hiding within that piece of timber.
