I have been working on an IPE/Boo bow for sometime. I have had some downtime with it lately as I am going to back it as I took the nodes down too much. So the bow hasn't been braced or pulled for 2 weeks.
But other than that, I notice it somtimes feels rough around the glue lines. It didn't two weeks ago. I was watching dean torgues video on boo backed osage and he said you have to keep boo dead dry because it sucks up moisture.
This roughness happens on a weekend like this one where it its 85% humidity outside and raining. I usually sand it off down to 1500gr sandpaper. So it appears the boo is contracting or expanding. This is the second time I have felt it, and same story, humid day. I know its moisture, because I took it overnight and put it in my closet and no more roughness.
So this brings up my question. What should one do about this? I started the bow in Feb when it was very dry like 20% or less in my house. Should I have sealed the bamboo after removing the rinds? Or sealed the area around the glue lines?
Dean says you should keep the boo in a dry box, but I figured that was until you glued it on, then it wasn't going to suck up any more moisture. I know the boo was dead dry when I put it on, because the humidity in the room I keep my boo got down to 9% for a few days due to a wood burning stove.

I alway sand my boo last just before I am ready to put the finish on..I would make sure it is dry do the touch up sanding and apply the finish..

Maybe I take too long to build a bow ;D
Thanks for the reply. Would you put the whole bow in a dry box for now? I do not have one built yet, but considering for the hickory roughed out blanks I have.

It wouldn't hurt to put it in a hot box at 85 or so for a bit.. then take it out and do your finish work..
