Building a Deck: Best Tool for Cutting Joists?

I'm planning to build a 12x16 deck next month. I need to cut a bunch of 2x8 pressure treated joists. My circular saw is a cheap $40 one and it struggles. Should I get a worm drive saw or a miter saw? Also I'm on a budget, so not too expensive but want something that lasts.

For deck framing, you'll be making a lot of cross cuts. A sliding miter saw is super handy, but can be pricey. If you're on a budget, look for a used one on Craigslist or FB Marketplace. I got a 10" sliding Ryobi for $80 and it works great. Alternatively, a worm drive saw will rip through those joists but is heavy and not great for precise cuts. I'd go miter saw.

Dude, get the worm drive. That thing will cut anything and you can use it for the whole project. Miter saws are stationary and a pain for long boards. Plus, a worm drive is a solid investment. My Skilsaw 77 has been going for 20 years. Yeah, it's heavy but you'll get used to it. And for budget, check out the Kobalt or Porter-Cable versions.

I'm more of a weekend woodworker, but I've built a few decks. Honestly, a good circular saw is fine if you have the right blade. A 40-tooth framing blade makes a huge difference. But if you have the cash, a 7-1/4" worm drive is the way to go. Also, consider a portable saw horses with a stand for the miter saw if you go that route – it makes life easier. Just my 2 cents.

Everyone's given good advice. I'll add: whatever saw you get, make sure it has a blade guard that works properly and get some proper PPE – eye and ear protection. Pressure treated wood dust is nasty too, so a dust mask if you're cutting indoors. Also, for the miter saw, ensure you have a stable surface to avoid kickback. Safety first!
