Miter cutting tall baseboard trim


What's the smart way to get a clean miter cut on tall (7-9.5") pieces of baseboard trim?
They are too tall for my basic chop saw.

Circular saw set on an angle and run on a rail?

Or are speciality chopsaws made for that? (I'm thinking of those sliding chopsaws. But that's basically just an easier, faster to.use version of setting up rails and running a plain cirrcular saw at an angle no?)

A sliding miter saw is nice but if you have limited use for it, a little expensive.
I would build a jig for the circular saw for the outside corners and cope the inside corners.

Re: Miter cutting tall baseboard trim


how long are the baseboard pieces ??
how many LF do you have to do ??
the volume of the task often dictates the tools required.

do you have the means to make a small router sled
to keep all your cuts uniform and fit well ???
sort of like the sled jig boat builders use for scarf joints
to join long boards together. except yours will be at a 45* angle.

one option you may consider is that if you have a lot of
90* corners to do, is to make your corners using 3 or 4 feet
long baseboards and scarf them to the longer pieces during
installation. done correctly, the joining seam will be invisible.
sort of like pre-made cove molding corners for the ceiling.

excuse my ignorance but what does "cope the inside corners" mean?
I sort of know what a coping saw is, but what is "to cope" something?

re: router sled.
I don't have a lot of space, expertise or special tools. I'm just trying to finish off a few pieces of baseboard as simply as possible. (I really only have about... 6 corners to miter)

Re: Miter cutting tall baseboard trim


Cutting what you can with your miter saw and finishing up with a handsaw is also an option.

The first piece goes in to the corner with a square cut the second piece is cut on the 45 and the excess is cut away with a bit f a back angle and the corner fits every time.

Re: Miter cutting tall baseboard trim


For the few cuts you have you might talk to your local rental store. A sliding miter say would allow you to make a few practice cuts to get nice closed joints. In the real world those inside and outside corners are often not exactly 90 and being able to cheat as needed will make for a nice looking job.

Re: Miter cutting tall baseboard trim


With a fine tooth blade on your circular saw, you can use a speed square to make the cuts on base molding, and make them fit really tight. I did this years back, and as rough as it sounds, you can make a really good joint this way. I also used the circular saw to make the straight cut under while coping, then used the coping saw to finish the profile.
