Hello Jim,

Welcome to The Router Forums.

Movement stability is a common consideration when selecting a species for many different kinds of projects.

Design issues such as the dimensions of the boards also come into play. In thicknesses over 3/4", Western Red Cedar is sturdy enough to be used as trim or for picture frames. It dents easily, but has a low movement rate with humidity changes.

Jim,

First, how big of frames are you looking to make?

What kind of trim or furniture do you have in the room it will go? Do you want them to match?

How much do you want to spend on the wood?

Picture frames are a great way to use more expensive wood, since you don't need much of it. I've not used exotics, but I have made frames out of poplar and red oak, and they've done fine in the Virginia humidity. I've finished them with satin poly.

If you are going to make a frame for a room with painted furniture, you can use MDF, which paints well and doesn't have wood movement issues.

Another thing I forgot to mention was that a lot of people make picture frames out of surplus or used hardwood flooring. I picked up a box of hickory and a box of oak flooring on close out from Home Depot for $50 a box (17 sq ft total on the hickory and 22 sq ft total on the oak). Anyway even after cutting off the tongue & groove, it worked out to be a lot cheaper than buying 'craft boards' to get the wood for jigs & misc small projects that need hardwood. The only downside to it is that the boards also have two grooves on the backside of them. Not that big of deal and kind of a plus for making picture frames as it makes them less likely to warp.

As the humidity changes the entire frame changes. This is usually only a problem when something is trying to prevent the movement like a panel across the frame. I read something recently where the author said "Wood is going to move- period. So let it move."

Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.

It's the mitres that get you with picture frames though isn't it. Especially if the frame stock is wide. The challenge is how to stop them opening up on the inside when the wood shrinks across the grain, or on the outside if it expands.

Howdy Jim,

I agree with Chuck let the wood move. I would recomend reinforcing the frame with a spline. You can use an internal spline but I like to use a contrasting wood and expose it, very fast to do and since the grain in the splines is at a 45 degee angle to the frame itself, it helps as my father said to control wood movement . Have it push against each other. being from s.e. Texas we are no strangers to humidity and it works here.

Reading some of the other ideas here and thinking about them led some more ideas to pop into my head.

I have always known that I can't keep it from moving! Since I took the plunge into wood-crafting I have been on the lookout for better ways to 'move with it'

An idea that popped into my head was to use lumber cut in a way where the movement was focused on the thickness, instead of the width. In the uploaded image, the movement trends for several common styles of mill cuts are shown by drawing a smaller box for the shrunk size, just inside a slightly larger box for the expanded size.

When I saw the word 'contrasting' in your suggestion, the idea that popped into my head was putting a 'trim piece' in the middle of each miter, possibly of a different species so that it would really contrast. the thin trim piece would help buffer the seperation attempt, especicaill if it was a double rabbet sort of thing where it was wide in back and skinny in the front. Corner pieces like that should make it a lot stronger to, not that it really needs more structural strength.
