Apologies if I break any rules with this post, please let me know if I do.
I am an utter novice when it comes to woodworking but I want to get into it as soon as I have the time/money and I decided a good place to get my hands dirty is trying to fix some of the second-hand furniture I'm gonna be getting for my new apartment.
I bought this lovely desk which is mostly in pretty good shape except that the back legs are kinda loose and crooked. When it's standing, I can use it well enough without any wobbling but I'd love to fix them anyway.
It looks like they were removed and glued back in at some point as it seems like there used to be a bar going from leg to leg.
I could remove one of the legs with a little force and unscrewing movement but the other one seems to be glued tightly.
How can I unglue that leg without damaging the desk?
How can I put them back in so that they stand perfectly straight like the other two?
Bear in mind I have no tools or experience, but willing to do whatever is in my means!
Based on the comments the mortise has a loose bit as seen in the picture, so you are definitely right that I should address that as well.
