This is in regards to the nightstands I have been working on in my free time since back in November….I hope they will be close to finished by end of April but we’ll see. Sorry I haven’t posted progress blogs, but right now I’m just trying to get it finished and have been picking up speed lately. I’ll take pictures when I can actually start dry-fitting.
Now, on to the question:
I live in Indiana, and have been working in my garage all winter in temperature range of 55-65 degrees. I don’t have a humidity measure though for the garage, but know its pretty constant since my boards haven’t warped since acclimation time way back in October. Anyways, since I am building this in Winter and have read that I should account for summer time expansion, I’m wondering how wide the rails can be from leg to leg.
The panels are Cherry, 5/8×13 1/2×19 1/2, legs are Hard Maple. I was planning on having a 3/8” tongue on all edges of the panels and 3/8” grooves on the legs and rails. First, is 3/8” enough?
Now, I want to make sure I make my rails long enough to account for the extra expansion room. If the panels are 13 1/2 in Winter, how much wider can I expect them to expand by summer? These nightstands will be indoors with AC on in the summer.
At 13 1/2” width it means the area that would be sitting between legs outside of grooves would be 12 3/4” So, would 13” rails be long enough to account for this extra expansion or is that too long?
Also, I am undecided by I might buy some extra wood and edge joint another piece onto the panels to these to make the nightstand a little larger like originally intended. So if I brought panel to 18” width (including 3/8” tongues on both sides) then how wide could the rail be excluding the tenons.
Any help would be great. Thanks.
