After I glued and clamped two pieces of woods together, I found wood crack (not in the gluing area) at the end. Is it because I clamped too hard or just wood is not good quality? What can I do it? Could I cut it off to prevent further crack? Thanks.

Hmmmm.
So many questions
What kind of wood?
Is it necessary to have the full length that you glued up? Then take some of the sawdust, mix it with glue and smear it into the crack.

Generally, so long as your edges are straight you just use enough pressure to make the glue seep out.

My $.03

-- No piece is cut too short. It was meant for a smaller project.

are you sure that the crack wasnt there before you glued them up?

As you may know, I am new to woodwork (much complicated than I initially thought). I don’t think it had the crack before I glued up, since I manually plane it everyday. The crack is very thin <1/100 inch and around 3/4 thickness of the wood. The wood is oak. Your suggestion is highly appreciated!

get some thin instant .cycranalyte (spelling), glue and flow it into the crack, it will be thin enough to fill the crack,and let it dry naturally, do not use the activator, it makes it too brittle, i suggest you put some masking tape along the edges of the crack so it doesnt flood the rest of the surface, or it can fill your grain and also prevent stains from taking, and as small as it is to simply force some glue and SANDING dust as mentioned above into it will also do well…as to why…who knows…its wood, and often things of this nature “Just happen”...but as a precaution always know that wood dries out the most on the ends, thats why end grain checks ( cracks) are quite common, and are usually always present, when dealing with rough sawn lumber, it is very common to have to cut the ends off until you get to sound material, and some times we just dont cut back quite far enough, and some times even when we do , we have opened the wood up and it dries a little more and a small check will appear, for this reason i always glue up longer than I need and then trim back…just in case

Hi, Where could I buy cycranalyte? Next time, I will be more careful. Cut more off from the end. Thanks.

Try Gorilla Super Glue.
It is a Cyanoacrylate glue that remains a little less brittle than other types of Super Glue.
I use it and like it.

Note: This is a different product than the original Gorilla Glue.

The common name for this glue is SUPER GLUE and it is sold everywhere from the dime stores to high end stores. ...of course some are better than others. Also if the crack should widen use clear epoxy mixed with some of the same wood saw dust to fill the crack, also works with chips and dings if there is no stain used in finishing.
