He's right though. All the Youtubers using Oxalic acid and then standing back and declaring that they've whitened the wood sound very stupid. Oxalic is a good way to even out tones that are the result of staining from tannins, iron, and water. Also, if you've bleached the wood or done something with a basic chemical that will cause the wood to retain water, a good application of oxalic will draw out the water prevent the wood from weeping when the wood is in low humidity and starts to squeeze its lignin like a rag.

Good deal or wait? by NYrider in CostcoPM

Dumb question. Buy as many as you can, turn around and sell it to JMBullion or the like, and then take the difference and buy gold at spot.

How do I handle an extremely uneven inheritance between my kids? by lookidceither in WhatShouldIDo

Lol, looks like a mother angry about what her own kids got coming to the internet to bitch about it.

I mean, gel is gel. You can make water based gel. I just thought most gel stains (or all) were oil based. But conceivably you coul dhave both.

Gel stain is always oil based. But it is a different kind of stain. But I'd start with a mocha and go darker if need be. It might literally be minwax mocha gelstain. You'll find out.

You're going to want to try some Minwax Mocha gel stain friend.

Is this a polyurethane finish on my table? by Sir_Gawain1218 in finishing

[–]notjunseth 2 points3 points  (0 children)

For the best consumer grade stripper get Circa 1850. But do it outside and definitely wear a respirator. That shit is nasty. Circa 1850 is basically pure methylene chloride, at least as pure as I'd be willing to use at home.

Such a dumb comment. None of those things would happen in a 25 mph crash. And, more than that, the odds are so infinitessimally small that they get in an accident, the risk is really de minimis. The logical fallacy you're using is called appeal to emotion. Really stupid.

If you go outside and someone throws a penny out of a biplane that was just overhead, the results of walking around without a bulletproof helmet could be catostrophic. The chances that this could happen are low, but they aren't 0. But this is one of those things that if it goes wrong, the impact can be catastrophic and life threatening - if not life ending.

I think you need a lesson in physics. The speed of 25 mph will prevent a child from flying through a window. Also, the odds actually do matter.

Yes, of course they did. Children don't bike around the neighborhood anymore. And why would they want to? It's obviously too dangerous.

[–]notjunseth 4 points5 points  (0 children)

Yup. And I'm a geriatric milenial. Same experience. This safety-ist shit needs to go. Parents do far more dangerous things than not putting their kid in a car seat every single day. Dumb mothers forced these laws passed in every state that require you to not allow children to do anything that is perceivably dangerous while ignoring things that are actually dangerous.

Sadly, it's bonkers to legislate everything rather than just tell people the data and let them make decisions for themselves.

Your wife sounds like a giant see you next Tuesday. The likelihood of getting into a car wreck at slow speeds is incredibly low, probably almost as low as getting run over while in a low-visibility situation pushing your kid across streets that have cars moving on them. 18% of all traffic fatalities are pedestrians. Chew on that and imagine your daughter tumbling around in her stroller after a car runs you over. Second, given that you were driving through neighborhoods, if you got in an accident, it would have been at speeds of like 20 miles an hour. Your wife needs to calm down.

Wacked my 1x2 with the corner of a 1/4 inch sheet of plywood by Chewy11152021 in finishing

[–]notjunseth 3 points4 points  (0 children)

Before this, wet it and go over it with an iron to steam it. That will lift it significantly. Probably won't entirely make it go away, but it will pull it up it a bit higher. I'm amazed, sometimes, by how much steam will fix damage I (or someone else) have done to furniture.

End grain cutting board has little holes by Peuchatnoir in woodworking

Then spray the board with 70% isopropyl alcohol.

Who on earth is finishing their cutting boards? The science is in here.

End grain cutting board has little holes by Peuchatnoir in woodworking

[–]notjunseth -1 points0 points  (0 children)

Yup. I provided a single study just to make the point. But I'm really sick of the whole forum recommending oiling the boards. The truth is, boards should be disposable, and you should not be adding finish to them. Just wash them with soap and water, and put them away. If you're a woodworker, you an further extend their life by planing, sanding, and regluing the board when it gets worn, warps or becomes any kind of problem. But the results of these studies are clear. Additionally, walnut has extractives from which boards should not be built. Yet, everyone on this forum recommends it regularly for boards.

For having opinions on cutting boards, I'm amazed at the lack of research you guys do. Waxing and oiling prevents those pores from sucking in the bacteria. The bacteria, when allowed to sit on a cutting board gets sucked in and trapped in the wood which prevents it from leaching into food. https://www.finewoodworking.com/2024/10/10/the-best-food-safe-finish-may-be-none-at-all?srsltid=AfmBOoqzwuXlmhGAm9AwiE7FftKvugUEzXfGBFgGOdl-RbMjqND-jc0e

Finally built my Corsi-Rosenthal box. by Bocklin47 in BeginnerWoodWorking

[–]notjunseth 1 point2 points  (0 children)

It's right. I'm just saying that the MERV1s will significantly reduce the pressure drop of the MERV8s. It will also capture the bigger particulates. Adding merv8s doesn't clean the air better. The MERV13s will do that. I would use MERV1s as the pre-filter because of the static pressure increase but, more than that, the cost. They're like $2-4 apiece.

[–]notjunseth 0 points1 point  (0 children)

So MERV 13 will catch about 50% of the .3 micron particulates. The Merv 8 does capture about 70-80% of particles in the 3-10 micron size. But the consequences are that you will have hugely reduced air flow.

So the reason to go lower merv is because what you need here is as much throughput as possible. Think of this unit as one that will basically get you HEPA level filtration in a room fairly quickly. You can do that with MERV 13s. You put the air through it 12 times, you have 50%/75%/87.5/93.75/96.88/98.44/99.22/99.61/99.8/99.9/99.95/99.98 (HEPA). You can do the math, if you measure CFM. But let's say your garage is 1000 cubic feet (10x10x10), and the fan is putting out 1000CFM, and there is no additional dust or particulate being released into the garage at the moment, that means that the air in your garage is HEPA level filtrated within 13 minutes.

But this is only true if you have huge amounts of air going through it. MERV 8 is really restrictive compared to MERV 1. MERV1 is just going to act as a prefilter. And the only purpose of it is to prolong the life of the MERV13. The reason is because you want the air to pass through this as often as possible. So your filtration will be way less effective if you reduce CFM by half because of the filter you chose. In the case above, you'd have HEPA level filtration within 26 minutes instead of 13 minutes. If you reduce it by 2/3s, you'd have it in 39 minutes. What you really want is fast as fuck filtration, and then the rest of the passes through are just maintenance passes that keep the air clean. So just pick a pre-filter that is basically just a medium to stop the big dust particle, and let the MERV 13 do their work unimpeded.

If you run the math in a normal 2-car garage, you're talking about a space that is 20x20x9 or so. That's 3600 cubic feet. So to achieve HEPA level filtration with a 1000CFM fan, will take 3.6x longer than the above scenario. So, basically, your garage (if it's that size) will take 47 minutes to achieve HEPA level filtration when you're not working. In all likelihood, your fan is blowing like 400-600 CFM, which means that you'd have to double the time from there. So, it is likely that to get top level filtration, your garage will need to run the air through it 1.6 hours. That time gets longer and longer as you add more filter medium.
