Two method's to fill cracks
One method I use is to run blue painter's tape down each side of the crack to protect as much as the visible grain as possible.
I then run a line of glue (of choice) along the crack and use a pliable spatula to force the glue in the crack. Much like forcing grout between tiles. The pliable spatula can be a autobody applicator or a pot cleaning thingy.
Another method that works very good with thinned glue is a syringe and needle. A diabetic, nurse friend or a Veterinary Store may be able to help obtain a new one. Avoid any used ones.
Adding matching sawdust to top layer for either method helps to blend the tone.
One needs to observe the wood closely to determine if clamping is required or even desired. If the wood has begun to check and is not yet dry, any repair that is clamped is really going to stress the wood.
