Ok, so I bought these two 3" thick slabs of cherry with the intention of making my next bass with, soon after receiving them I noticed they started to check. I kept an eye on it and they got worse to a point, but then seemed to stay the same. By this point they had reached the section I would have been using for said bass. So I put them in my garage and wrote off using them. That was about 3 months ago, now I'm planning on building a guitar, which has a smaller body, so I thought I could dig them out and see if any of the cracks would be present within my template. But when I got the wood out of the (damp) garage the cracks had completely healed up to the point where they are invisible. So, I'm guessing after bringing them in the house they are going to open up again as they dry out a bit. This was last night and they haven't opened up yet. My questions are these. Firstly is this a sign the wood is not yet fully dry? When I bought it I was told that it had been air dried for around 5 years. Secondly is there any way I can use this to my advantage (them opening and closing)? I was thinking of marking all the cracks when they next open up then putting the wood back in the garage so they close up, then injecting CA into the area to hopefully hold them closed. Thirdly, may new cracks form, or were these most likely old cracks which first happened when the wood was dried? If there's a chance of more just appearing after I have worked on it for a month I would be happy to just scrap it. Or cut it into laminates. Thanks!
