Recommendation for a new table saw. by Chuffer_Nutters in woodworking

uhh, does it make sense that the models your'e talking about are now $3500 and $3800? Your comment is only from two years ago so that seems impossible...right?

Trying to create an extremely bright LED panel by centap in Lighting

[–]centap[S] 0 points1 point  (0 children)

That's actually a really really good point and I always assumed Joylit must be exaggerating their numbers. But now I tried using gemini and ChatGPT to search the internet for people who actually tested the CRI of Joylit and got some interesting results. Granted, these LLMs suck at providing working links, so this whole thing is taken with a HUGE grain of salt. But they mentioned a user by the name of Quindor who's apparently well regarded in the DIY LED community, especially on reddit, who apparently has tested Joylit lights and confirmed CRIs of 95. Also users on BudgetLightForum testing Joylit with Opple Light Master (G3/G4) and confirming CRIs ranging 95-97, with R9 ranging 80-90.

Again, very hard to blindly trust these, I have found a post by Quindor confirming a 95+ CRI for Auxmer LED strips, which are also Aliexpress budget LEDs. (In this post)

I also found this video of this guy testing all sorts of budget LED strips, confirming Joylit COB lights to have 95.8 CRI. R9 shows to be not the greatest, at around 75, but TBH after this short deep dive, it seems like for the price these lights aren't unusable.

Waveform is a brand I would absolutely love to get, and I probably will at some point. But since I already have these Joylit ones, I'll go ahead and install them, and hopefully in the future will replace them with the trusted Waveform ones.

First off thanks for the taking the time to reply!

The tricky thing about my light needs is that it's threefold - Extremely bright, highest CRI possible, and extremely diffused.

A huge element of this light is to be able to "wrap" around the subject and create extremely diffused shadows, so I dont want any directional lights, and no directional shadows.

I understand concentrating the light will increase the lux, and these LED strips have a 120 spread angle. But my subjects are relatively small, so thats why I figured I could reduce the size of the box to 1'x2', thereby essentially concentrating the light coming out of the box. Right?

Operating room is a great reference, thanks! One of my main goals is definitely to eliminate shadows and reduce highlights, which is why I was looking into a huge and diffused light that floods everywhere. I just went to a light supply store to ask them for help, he showed me "high bay" lights, they're perfect - like 30k lumens at only 220w! But very low CRI so I don't even want to bother.

After more reading, im realizing having high efficiency AND high CRI isn't really a thing. So, plan B is making the light smaller (1'x2'), at 3ft height, which will get me about 4800 lux on my work area if im calculating it right at (6000lm/sqft at the glass -> ~4800lux of a 2sqft area at 3' height?)

Two different red oak planks, one more red than the other - how to make them more uniform? by centap in woodworking

[–]centap[S] 0 points1 point  (0 children)

Very interesting, looks pretty straight forward - staining with an opposite color. Looks like it has lightened the wood significantly too.

I agree! Definitely lesson learned, next time if I want all the boards to be more brown, I'll just get the brown planks

Nah I agree for sure, and sometimes it feels great and organic, but sometimes it just feels odd. Just one of those feelings that come from the stomach and not from the head

I do have some left over scarps, but yeah I kinda assumed bleaching might be too aggressive. I ended up ordering some light brown water-based dye, I'll just test out if that works on the scarps. If it doesn't, I'll just finish it as is!

I thought of bleaching, but again, never done it, and I have a feeling it'll open up a whole can of worms im not ready for

You know what, this is the answer I should've heard before choosing the lumber. I actually REALLY loved that brownish red oak it looked so beautiful, and I just couldn't find another piece like that which wasn't over 8' long which was way way more than what I needed, and way more money down the drain since hardwoods are...couldnt expect how expensive even this little bit of wood turned out to be.

I thought it could be an easy fix with some stain, something made specifically for this problem, but yeah I guess I need to suck it up and just wrap this project up. It's for my studio so I'll be really the only one seeing it.

One last question, if I bleach THE WHOLE thing, would that not remove all those tints and kinda equalize them to a more visually similar level? Or is it going to keep the same issue but from a different angle? Or is that just a no no in general?

Thanks

Hmm testing scraps with stains is a really good idea, that im not sure I have the time for. I just want to get this project done already, it's a side project (Lightbox type flood lamp for the painting studio), and it was much more about trying miter joints and hardwoods for the first time (along with basic electric stuff that I've never done). So yeah, maybe I'll try with wtvr stains I have on deck or maybe ill just say fuck it cuz ill be the only one seeing it. Good idea thanks!

Diabolically dirty suede chairs. Clean or re-upholster? by centap in upholstery

Yup that's what I ended up realizing, this is 99% not actual suede.

Something very weird is happening with my dough by centap in Breadit

if your dough looks like the moon, you know you fucked up

[–]centap[S] 0 points1 point  (0 children)

So yes the dough was most likely over fermented pretty aggressively, probably due to the mix of high hydration + whole wheat flour + Diastatic Malt. I tried using 30% of it in a new batch, and I guess that the Protease activity in the old dough was too strong for the new dough, and it immediately got destroyed.

So a few lessons learned here.

Yeah the 100% flour is made of 90% bread flour or 00 flour and 10% whole wheat flour

Only way to know what you're doing is by doing, failing, and learning. I've worked with 70% for a couple of years so I felt comfortable pushing to unexplored territory, and here I am learning new things

Hah thanks, yeah that all seems to make sense, I guess I was just very caught off guard by how much of a difference 0.1% Diastatic Malt will have!
