Timber mantel end checking
I have two hard maple timber mantels that I rough cut about a year ago. Since then, they have been air drying in my shop. They were both cut around 8' long and have since checked on each end about 5/8" wide and 12" to 18" deep.
This past weekend, I cut the mantels to length which almost removed the checking down to only 1/8" or so. I'd like to hammer in some sort of clamp, maybe an S-shaped piece of metal or something to try and hold the checking.
I've searched and can't find anything on the internet that would work. I feel like I've seen something similar on railroad ties. Anyone know what I'm looking for and where to find them? Thanks
