Sorry to sound like a broken record. I do not have wood allergies. I’m just a regular person. I was not diligent enough on dust control early on. I now take medication every day and will for the rest of my life.
We can’t all do a perfect job of collecting spoil. I do always recommend that you do the best that you can in the room you have and with the budget you have. I also start all responses to the question of “what tools should I get first?” with number one being dust collection.
I am not some kind of dust collection wacko that thinks anybody who doesn’t do perfectly with their dust collection system is doomed to a horrible death. Let’s just use common sense and do the best we can :-)
IMO, DC is very important! Obviously, the crap you breathe in isn't good for you but, how about the time you spend cleaning up all the dust you're making instead of continuing to work on projects? And, to boot, There's some pretty inexpensive options out there!
Again, just my opinion but, you need the big 3 first. Table saw, jointer, and planer. Coming in at 3.5 would be the dust collection. I'd rather work on projects that clean the shop.
As an additional note, the more energy you invest in good dust collection the more enjoyable spending time in your shop is. You'll note I said energy, not money. As I said before, there's lots of inexpensive options out there.
While its definitely a concern, how many people are utilizing it?
Is it more important for someone in their shop 24-7? Obviously breathing in wood dust is harmful, but growing up we/I didnt know any better in my time at least.
So my main question is when do you guys feel like you need it? To be clear let's hear from the guys with a dedicated wood shop. I understand if your shop is in the basement/ garage and dont want to get it in the house. Eventually I suppose it's a necessity, but when do you add it to your set up?
There is room by all means. I just cant help but think the money spent on a 240v is overkill for me. Its money that can be spent elsewhere. With that being said only 2 of the saws I mentioned can be wired for 120v. One comes already and the other is an add on. Add one cost so....time to look at wire
You did not buy a bunk slab, you bought a slab with the pith through the middle, you have only one solution, cut the pith out. Any other attempt to prevent cupping will not work.
As for the white spots it’s hard to tell but I’m betting the inside of that slab is a lot wetter than you realize, definitely wetter than your outside readings.
One positive, once you cut out the pith you’ll have two nice quarter sawn pieces.
