Thank you for the reply Rob. I purchased this table used. The split is not the whole length of the cross-member. It stops about 7 inches before getting all the way across. The pic is taken in the middle area of the table where the largest of the separation is.
Thanks!
Rob's suggestions are good ones. As an experienced woodworker, I can tell you that splits like this are easy to fix.
1. Clean out the crack as best you can. Gently pry it open a little and use a strong vacuum to clean out any debris that may have fallen into it (or compressed air to blow out the debris).
2. With the crack open, squirt some wood glue (Titebond is good stuff) along the length of the crack. Be generous, better too much than too little. It's pretty fluid and should run down the crack and leak out the bottom, so watch for that.
3. Clamp the crack closed, using as many clamps as you can. A clamp every 12 inches or so would be great. You will get a lot of glue squeezing out. That's ok, just wipe it up with a damp sponge. The glue is water soluble.
4. Leave it clamped for 24 hours. Depending on how well the two crack surfaces mated, the crack could now be essentially invisible and the piece stronger than the original wood. Wood glue is remarkable stuff.
5. If you don't have clamps, follow Ron's suggestion and use screws to close the crack. That will work well, although if you have clamps, the screws aren't necessary and the finished product will look less "repaired"
