1st board bow cracking

[morerightrudder]

Working on 1st board bow and have backed with drywalll tape.  This is a piece of oak from Lowes. I can hear the first sounds of cracking while tillering.  Do I continue and work under the idea that it aint broke until its broke or should I assume it's broke and move on to the next one?

Cracking is not good. Post pictures but do not continue.

Could be the glue and tape making the cracking,sound.
Usually if a splinter is raised it will be one crack sound.
Just a quick "tick"
If you have a pulley system where you can stand back while exercising then you could continue safely.

There arent any visable cracks but the noise SCARED me.  It was also the first time i exercised the board since adding the backing.
