<p>Did you leave the flat panel on a solid surface without equal
airflow on both large faces?</p>
<p>I did that once to some cherry panels - and got me a Pringle the
next day<br>

style="font-size:12.0pt;font-family:"Arial","sans-serif"">I’m
making a photo board for my granddaughter (believe it or not
they are actually printing pictures and the Polaroid is
making a comeback). She likes rustic so I was going to make
it out of pine (knots and all) and put a barn wood finish on
it. Since it was going to be rustic, I figured I could skip
a milling step and purchase 1x4 boards at Lowe’s. Most were
badly warped but I found 3 - 10’ boards that were relatively
straight. I thought that since they acclimated in the store,
they should be good to go. Plus I was going to chop up into
2’ lengths so I could manage the warp. I set them aside in
my climate controlled shop and went to finish the concrete
truck for my grandson. When I went to retrieve the boards,
they had warped badly. I knew better but I used them
thinking I could force them straight at glue up. When I went
to clamp them up, my heart-of-hearts knew it wasn’t going to
work because they were warping at glue up. I had gone this
far so I glued up, clamped down to a flat work bench and
hoped for the best. Sure enough, when I removed the clamps,
the panel was badly warped (unfortunately, I was not
surprised).<o:p></o:p></span></p>

<p class="MsoNormal"><span
style="font-size:12.0pt;font-family:"Arial","sans-serif"">I
realized I should have done what I planned to do in the
first place and go get 2x4’s so I could mill the warp out. I
got pretty straight 2x4’s and chopped into 2’ sections and
,milled down to 1 ¼”. I stickered on my bench and let
acclimate to shop for a day. Encouraging because as you
looked at the stickered stack, they did not appear to be
warping at all. So next day I milled down to just under 7/8”
and stickered again overnight. Again stack looked good so I
milled to final thickness of ¾’. As I was gluing up, I was
very encouraged as the glue up was flat. No need to clamp to
bench (I did anyway) but was very encouraged. Yesterday
morning I unclamped and held my breath but, hooray, a flat
panel. I sanded panel to remove glue marks and set aside to
practice texturing sample boards for the barn wood finish
(still nice and flat). This morning, I went into the shop
and the panel was warped!! As I write this, I clamped the
board flat to my bench and started to bring the temperature
up in my shop. If I’m not working on anything, when I leave
the shop for the night, I hold temp to 50 degrees but if I’m
working on something, I hold temp to 61. Why 61? Because I
bring up temp in 3 degree increments to get to 70. Why 3
degrees? I don’t know, I just do.<o:p></o:p></span></p>

<p class="MsoNormal"><span
style="font-size:12.0pt;font-family:"Arial","sans-serif"">So
I have questions: What happened? Is it the temperature
fluctuations (and does 9 degrees really make a difference in
warping)? But most importantly, what do I do now? I have
less than a week to finish. I could do again with new 2x4’s
but I’m not comfortable I wouldn’t have the same issue. As I
send this I’m going back out to unclamp from the bench but I
don’t expect it to stay flat.<o:p></o:p></span></p>
