I have a 26 gallon air compressor max 150psi and I want to put it in the back corner of my garage with a hose reel mounted on the ceiling in the center and another quick connect in the front of the garage for easy access. I am planning on using ½ inch pvc with glued connections to route the air because it’s cheap and easy. I have already started mounting some of the pipe but after doing some reading there are very mixed opinions on pvc. I’m in Southern California so I’m not too worried about brittle failure from excessive cold but wanted to knowing anyone else has experience with a similar setup or any advice for the project.

Tldr; why does my saw burn the wood?

I have a craftsman 12 inch sliding compound miter saw. It's using the original 12" blade. I haven't used it very much. Maybe a few dozen deck boards and some 2x4. Whenever I do a long cut like in the picture, I get a cloud of smoke and burn marks on the wood, usually more at the beginning and less later.

(Sorry for being a noob) I also get burns if I set an angle either horizontally or vertically. I rarely get a burn on straight cuts.

Is it just a dull blade? Can I sharpen it or is it not worth sharpening? Can you recommend a new 12" blade? I'll pay for quality if it's worth it, ie lasts longer

Maybe I'm doing something wrong. It only burns on miter cuts, not straight cuts. I suspect the wood moved, but I've clamped it down in several places and have the same result. It also burns both sides. I go really slow at first to minimize the burn, but that doesn't help. On this cut I pulled the blade to full extension, plunged to limit and pushed backwards. The burning stopped after the blade made it to the bottom of the plywood.

I propped open the guard to show the blade better. I don't cut with the guard open...

Thanks!

We have a pretty big, unconditioned attic that is all wasted space. The only thing up there is a furnace/air conditioner, which sits on a small platform accessible from the attic access panel.

The rest of the attic is simply ceiling joists, and loose insulation and insulated HVAC ducting.

Would it be a horrible idea to lay down some 3/4” subfloor-grade plywood, so at least the space could be somewhat usable for non-sensitive storage?

The attic space isn’t sealed, nor are the ceiling joists of the roof insulated/sheeted. I’d be laying the plywood directly on top of the insulation and joists. We would use it primarily for seasonal decoration storage or something.

Is this a bad idea? Is 3/4” subfloor overkill ($25/sheet) Could I use 1/2” osb or other cheaper plywood?

I’ve got little to no interest in finishing the space, I just would like to be able to walk around up there and move some stuff out of basement storage.

Thanks!
