Coped joints for baseboard

Posted by macvirtualasst (My Page) on

Hi All,

We are doing our baseboard trim soon. Is a coped joint where the two pieces of moulding meet necessary or can we just do miter cuts? We are having a hard time understanding why you can just join the two pieces together with a miter cut... Coping is new to us :-)

"We are having a hard time understanding why you can just join the two pieces together with a miter cut."

The odds of the two walls being exactly 90 degrees are between small and zero (even the drywall mud used changes the angle.

Coping greatly reduces the visibility of the small errors in the corner angle.

Install one side butted into the joint, miter the other piece, then cut away all the cross grain wood left on the miter.

It is not coped.

It is now coped.

I've installed miles of trim. Started out mitering, finding the angle of each corner, halving that figure, making the cuts and then tweaking each cut(sometimes using playing cards as shims on the miter saw) to get a tight joint.

Then see that joint open up with weather changes---humidity changes/etc.

I then learned to cope.

It seems slower, but is actually faster than tweaking a miter. And, the really good part is a coped joint does not expand/contract with weather nearly as much. Most times there is no noticeable movement.

The only miter joints I make now are outside miters---coped for inside.
