So, can you cut a 4×4 with a table saw? Yes, you can cut a 4×4 with a table saw if you have a 12″ table saw. But if you have an 8-¼-inch or 10″ table saw, you have to run it twice to get a clean cut.
Do you know the actual size of 4×4 lumber? When it comes to thickness, hardwood lumber in North America is typically marketed in “quarter” sizes; 4×4 corresponds to 3 1/2 × 3 1/2 inches or 89 × 89 mm.
A table saw’s capacity is usually around 1/3 the blade’s diameter. It’s hard to offer a single figure since there are different types of table saws with blades as small as 6′′ and as large as 12′′ or more.
Depending on the saw plate thickness, 10-inch saw blades can cut up to 3 inches thick in one pass. These are portable table saws used by both beginners and professionals alike. The thickness of a 4×4 is 3 1/2 inches. As a result, you must make one cut and then turn it over to make the second cut.
The accuracy of your work will be determined by your work holding technique. Stop blocks are quite common. However, safety comes first. Kickback may be increased by using a long 4×4 that is larger than the table. Use auxiliary supports as necessary.
How to Crosscut a 4×4 on a Table Saw
The miter gauge may be used to cut a 4×4 across the grain. If you have a 10-inch table saw, you will need to make two passes to cut all the way through.
To begin, elevate your blade as high as it will go. It should be a little more than 3 inches. Make a standard crosscut, and then flip your 4×4 over. Reduce the height of your blade so that it can cut through the remaining material, but not too high for safety reasons. You may use a router with a flush bit to make your cut flawless if you leave a little excess material after your second cut.
Quick Tip: Leave a little extra material on the desired piece to ensure the 4×4 will be crosscut at the right length. This makes the wood simpler to work with and allows you to gradually remove more material in a few more passes, resulting in a flawless cut.
How to Cut a 4×4 Lengthwise (Rip-Cut) on a Table Saw
Table saws have the amazing way to rip-cut a 4×4 like a fence post, something no other power tool can achieve.
Ripping a 4×4 on a 10-inch table saw works similarly to a crosscut. Because you know your fence won’t move, you’ll only need to make two passes with the wood this time, and the cut will be identical to the first. There will be no clean-up passes required, which is usually beneficial.
Just adjust the fence’s distance and lock it in place to prevent it from moving. Then lift the blade halfway up the cut, but not all the way. This allows you to cut less material on the initial pass, which speeds up the process.
Furthermore, avoiding having the blade cut the maximum amount of material at once helps to keep your table saw’s motor from being clogged and lowers the risk of the blade burning the wood.
Make sure your finger isn’t pushing where the saw blade will come out as you drive your 4×4 along the fence. It is strongly advised to use a push stick.
Cutting Thicker than A 4×4 with a Table Saw
if you have a 10″ table saw which can only go three inches deep, then flipping the workpiece over and cutting both sides that can often end up in an uneven face
- First, clamp the workpiece to the miter fence; that way, it stays nice and solid.
- Get the blade up as deep.
- Make a full pass.
- Now for the next step down, just over what’s left to cut.
- line this with the blade.
- Make another full pass, and there you have it.
- Use a router with a flush bit to make your cut, even if there are little extra materials.
Cutting a 4×4 with a Table Saw – Summary
There are two variables to consider while cutting a 44 using a table saw. The table saw’s geometry is the first consideration. The diameter of the blade, the arbor size and washer that clamp the blade to the arbor, and the amount of travel incorporated into the blade lifting mechanism are all important considerations.
By rotating the workpiece end over end and running it through a second time, you may double the depth of the cut. If you need to rip lumber that is above 6″ thick, you might consider utilizing a band saw. Band saws are better designed to cut through thick logs.
