Cut the Length
Next, take your top and side panels to a miter saw and cut them down to the appropriate length. The miter saw will make a cleaner, more controlled cut than the table saw, and is a better choice for smaller pieces of lumber. If your dimensions are too large to be cut using your miter saw, the cuts can be made on the table saw, but take great care to make the cuts as clean as possible.
If you’re building a radiator cover for the kitchen you may want to give it a custom look. Consider contacting your cabinet manufacturer to purchase materials similar to your kitchen cabinetry.
