Cutting Large Words on a Scroll Saw

Cutting large words on a scroll is simpler than you think. With the right material, blades and a few tricks, you can cut just about anything you set your mind to, regardless of the size of your saw!

Scroll saws are classified in size by the length of the throat, which is the distance from the blade to the back of the saw. The Dewalt  DW788 saw that I use has a 20” throat. 

 

Before we get into HOW to cut out large items, I want to review the different kinds of materials and blades you can use for various projects.

To know what kind of blade to use, it’s important to know what material you plan to use. For large cutouts, I typically stick to birch plywood or MDF. Because these materials come in sheets, you aren't limited to the size as you would be with something like dimensional lumber.

If I’m cutting out something large that will be attached to a backer, like a large word that will be glued to a round, I will use 1/2” MDF. MDF is a great material to work with because it’s easy to cut, and paints beautifully. However, MDF that is 1/2” or thinker can easily break if it is handled too much, so I wouldn’t recommend using anything thinner than 3/4” if you are doing a standalone cut out.

 

My preference when cutting a standalone word is 1/2” or 3/4” birch plywood. Birch plywood is very dense and hard, and has very minimal gaps in the layers. Many cheaper plywoods will have large gaps in the layers and because  you can see on the edges on your cut outs, you want to ensure you use a quality product that will finish nicely.

Birch is also much less fragile, so won’t break as easily as something like MDF.  It really is personal preference on what you use, but in my experience, birch plywood works best!

Now that you know a bit more about the materials, lets get into blades.

When working with plywood, choosing a blade that reduces tear out is essential because if you use a blade that is too aggressive, it will split your material and cause a lot of the layers to flake off. When cutting plywood, I would advise avoiding skip tooth or regular tooth blades.

My personal preference when cutting plywood is either a #5 double reverse tooth blade or a #5 MGT blade. Both of these blades have reverse teeth, which means they are cutting from the top and the bottom, allowing the blade to cut fast and clean.

Many people who are experienced scrollers may ask “why not use a spiral tooth blade?”. Sprial tooth blades allow you to cut in all directions, because the teeth spiral around the blade. And while this can help you cut out large items  I personally find spiral tooth blades much too aggressive when cutting finer materials like plywood and MDF. The kerf, or trace, of spiral blades is much larger than a normal scroll saw blade, and because they are so aggressive, the cut is quite rough which requires more clean up after the fact.

Now that we’ve reviewed materials and blades, it's time to start cutting!
