I just glued up a hard maple breadboard and I see an incredibly thin hairline check/crack on the end of the board. Looking at the end grain view I see the crack is about 0.5 inches deep into the 1.25 inch thick board. Looking at the top i see the crack travels about 1 inch long. It’s (now) obvious the end of the board was checked and I didn’t catch it

It’s about 50-60% humidity here in VT. It’s not a dry state, so that’s probably very normal. I had the board in my shop a week before working with it.

I don’t even think I could get the thinnest feeler from an automotive feeler gauge into the crack. It’s barely noticeable…but I do see it.

I wouldn’t worry about it if the board for me, but this is a paid job I’m doing for a co-worker and I want to see if I can salvage this board. I don’t want to shorten the board because it’s just the right length that the buyer ordered and it’s massive and I have some raw material costs and time and effort into this.

I have thought of trying to do some spot application of CA to seep into the wood, but i’m not sure if that is a lasting fix. I also thought of using my router and a 1/8 inch spiral bit to router the cracked area and then make a perfect fitting plug and titebond III it in there.

What are other options that might be easier/better?

use your shop vac on one side and pour pva glue in the other until it comes through.

Clamp the snot out of it for 24 hours, sand down, finish as normal.

Dallas: I would do that but the check/crack doesn’t go from the topside through the full 1.25 inches and make it through to the bottom.

Have your say...
