Help! Why is my wood stain leaving lines in the wood?

(ignore the blue tape) I’ve been trying to stain some ash wood (for a guitar project) and I’ve been practice staining some scrap ash wood. However, every time I try to stain it, it leaves these streaks/lines of unstained wood. Why isn’t my stain working? I’m using a trans-tint dye (red mahogany). I’ve mixed it with water, water + denatured alcohol, and pure denatured alcohol; I’ve tried sanding to different grits and pre-raising the wood and sanding, and NOTHING WORKS. Someone please tell me what I’m doing wrong.

Possible warping on this style of tabletop?

I have a peice of furniture I made awhile ago in school things didnt turn out the best so im repurposing it and turning it into a low coffee table. The only problem is the pannels from the peice are 18 wide were the lenght is shorter than the width. The way it was build it could pull that off but in a coffee table if I made the pannel 2ft wide and 18 long could the fact that its made 6 boards cause the pannel to bow or cup significantly? Would alternating the grain direction of the parts of the tabletop mitigate this or is this just a bad idea.

What’s the next step?

Finally decided to replace the original uneven top with this piece of wood, got the hardware set up fine, w brackets to support. I am not fully sure of the next steps to make this kitchen island safe. I assume it’s a combo of sanding, adding something onto the wood to make it water resistant and safe for like using cleaning spray. (Also if I would like to paint it black, what step would that come in?) any help is greatly appreciated. First timer lol

Best way/product for this?

I need help getting the black stuff off this wooden table. There was a bag of trash that was sitting under a pile of stuff that leaked black sludge causing this. Is there anything I can do or any products I can use to get this out? Thank you in advance.

Apple?

I was given this cookie but friend didn’t know what it was either. Fairly heavy for the size, seems harder than cherry, big leaf or walnut from my normal woods I use often. When sprayed it has more of a reddish hew to the wood. Splits make me think of apple but I may be way off too. In Washington state but cookie could have came from elsewhere originally, no idea. Any thoughts? And thank you!

My first project made from left over 2x4

I learned alot doing this project with bare amount of tools

I can’t bring myself to throw out the big foot innards. I feel like I’m throwing out their souls. Looks like I’ll be building a shelf in the shop for them.

Wood species help

The back where the holes are drilled out for hinges is a light color. looks like maple to me. The grain on the panels and face frame is throwing me off.
