Anyone else ever feel like a pro until the skirting boards come out?

The most reliable way to find those wierd angles without a digital gauge is to just scribe them directly onto the floor. You take two offcuts of your skirting and lay them flat against the walls where they meet. Trace the outside edge of both pieces so the lines intersect. If you draw a line from the actual corner of the wall trough that intersection point on the floor, that's your exact **miter line**. You can then set your manual bevel to that line and transfer it to the saw.

I ussually keep a dedicated pair of "test blocks" in my kit for this. They’re just two 6-inch pieces of the same skirting profile. I’ll cut them at what looks like the right angle, hold them up, and then adjust the saw by half a degree or so untill the joint is tight. It saves alot of wood compared to burning through full-length pieces. Even with a fancy digital protractor, walls are rarely ever perfectly plumb or flat, so you’ll almost always have to tweak that final cut anyway.

If you're looking for a new tool, look at the **Starrett 505A-12**. It’s an analog miter protractor that gives you the actual cut angle directly on the dial. No batteries to worry about and it's way more durable than the cheap plastic digital ones that tend to lose calibration if you drop them once in the van. Skirting is one of those tasks that looks easy until you're dealing with out-of-square garden rooms or buildings where nothing is a true 90 degrees. It’s the difference between a rough framing mindset and a finish carpentry mindset. Once you get that floor bisection method down, you'll be able to fly through the next one without needing a tutorial.

I'm still at the stage where I just stare at the corner and hope a standard 45-degree cut magically works. Does that floor bisection trick work for vertical corners too, like if I'm doing trim around a door frame that's wonky? I've been looking at those cheap digital finders because they seem easier to read, but if they break that easily, maybe the Starrett analog one is the way to go. Is there much of a learning curve to reading those dials correctly when you're in a rush? I usally end up second-guessing myself once I get back to the saw.

Instead of just mitering everything, I started coping all my internal corners years ago. It’s a game changer for garden rooms where the studs might have twisted during the build. You butt one piece square into the corner and then scribe the profile of the second piece onto the face.

Once you cut that profile with a coping saw or a grinder with a sanding disc, it doesn’t matter if the corner is 88 or 92 degrees—it’ll look perfect every time. For outside corners, I ussually glue and pin my miters togehter before they even touch the wall. If the joint itself is tight, you can just shim the back of the board to make it flush with the plaster.

Garden rooms are tricky because the temp swings make everything move before you even finish. For those outside corners that are way over 90, I usually just shim the back of the piece against the fence of the miter saw. It gives you that tiny bit of extra angle without having to reset the saw a dozen times. Also, if you're using MDF skirting, watch out for moisture. It swells if you look at it wrong, wich ruins your tight joints. A little bit of 2P-10 adhesive helps alot to keep those miters from opening up later.
