| Jan 31 at 11:38 | comment | added | psmears | @FreeMan: "useable" is listed in the dictionary as a variant spelling - no need for a "(sic)" :) | |
| Jan 31 at 1:37 | comment | added | Nelson | Relative humidity is, well, relative... If you have +3% every day for 2 weeks, your wood is now probably sitting in water. | |
| Jan 30 at 20:01 | comment | added | popham | @FreeMan, people's heuristic for "it's humid outside" is based on dew point, not relative humidity. See weather.gov/arx/why_dewpoint_vs_humidity. Your relative humidity might not vary as much as you anticipate. | |

| Jan 30 at 19:35 | comment | added | FreeMan | Thanks, @matt. Always good to double check things! For the work I've done so far, I've trusted factory edges. As I get the shop set up and start in on cabinet/furniture build, I most certainly won't though! | |
| Jan 30 at 19:34 | comment | added | matt. | Our sister company is a commercial cabinet shop, we never trust factory edges for square. I always over cut our parts and then true them up with a custom jig we have and then make our second rip cut with the TS. Just to be clear, I wasn't dogging on your answer, was genuinely curious as to why you thought it was unsafe. You raise valid points and adding them to your answer was a good idea IMO. Nicely done. | |
| Jan 30 at 19:29 | comment | added | FreeMan | Yes, @matt. a riving knife will definitely help, but I wouldn't completely count on it. Besides, you'll get a beveled cut (the swollen edge will lift the board) and would need to run it through a 2nd time to get a 90° cut. You might also have difficulty with a no-longer square edge running against the fence. All in all, I think it would be safer to make the initial clean up cut with a circular saw, then square it up again on the TS as needed. | |
| Jan 30 at 19:21 | comment | added | popham | You might be surprised on the stability of indoor humidity versus outdoor humidity depending on the location. I looked up Columbus, OH the other day because of some lady's truss movement. I discovered that their outdoor relative humidity stays within about +/-5% all year. Heating that air in the winter will swing the relative humidity way down. | |
| Jan 30 at 19:21 | comment | added | matt. | Isn't that the exact purpose of a riving knife? I understand kickback, have seen it before as well, in shop class. +1 anyways, solid answer. | |

| Jan 30 at 18:17 | comment | added | FreeMan | Because it won't lie flat on the table. As you cut into it, the flat, non-swollen part will want to sink down, while the swollen part will remain raised. That will cause the board to pinch on the blade and a pinched blade will kick back, launching the wood back at you. Waaay back in Jr. High school, I saw the results of kickback. Someone in the shop class before me was ripping a 2x4. It kicked back, shot the board more than 30' and left a 2x4 dent in the chalk board. You do not want to be there when that happens. | |
| Jan 30 at 18:15 | comment | added | matt. | Why would swollen particle board be unsafe to cut on a table saw? | |
| Jan 30 at 18:13 | comment | added | FreeMan | OTOH, penicillin was originally made from mold, so some of them are pretty darn beneficial. | |
| Jan 30 at 18:03 | comment | added | KMJ | OT: Mold is a bit scary because we haven't figured it out yet. Go read up on Valley Fever if you're curious about it. We're still figuring out what mold is a problem and what mold is not. | |
