Okay I figure there isn't an existing thread I'd be better posting this in. Just stripped the polyurethane down off this Japanese Oak tabletop and sanded it to a smooth 800 grit. Probably overkill and might need to sand it back to something coarser, but at least it feels nice. So I'm wanting to lay down a new finish on it and I'm getting conflicting information online; some recommend tung oil, others recommend polyurethane. I was wanting a durable finish and I assume tung oil wouldn't provide the kind of hard surface layer that you get from PU, but it was highly recommended by the guy at the hardware store as he used it on his table.

Can post more pictures of the tabletop if you want to have a good look, but it is a little pock-marked from decades of use. The original tabletop was Kauri, but it was real marked up since it's a soft wood and was removed perhaps 60 years ago. Damn photo better not be sideways.

TL;DR: what finish do I use on my japanese oak tabletop? I don't live in the states so some of your brands might not be available, but general recommendations would be greatly appreciated.
>>
>>1595601
Poly would be better, especially if your putting a coffee mug or a cold drink. Tung oil won't offer the ease of mind that poly would and poly will still show the wood off without it looking like plastic (like a laq would)
>>
>>1595608
Sounds reasonable. I've heard of putting oil down to make the wood shine, and covering it with an oil-based polyurethane, ever come across that?

Wood vs fiberglass. What's best for which applications?

It's called a regulator. That broom at the front and the plows are for moving the ballast.

Heavy snow in the west is cleared with a rotary snow plow.

Lighter snows are cleared with a wedge plow. Picture related.

They are also used out east for 'heavy snow'. IE 'lil bitch' snow. If you can see the top of a semi truck above the snow but you still think its a lot of snow, its 'lil bitch' snow. When you can't even see the tops of the trailers anymore, then it's really snowing.

I want to make a small setup that would mimic the rising of the sun at a time that I choose. How would /diy/ build it? This is my guess at the basics of it but I don't quite have a parts list assembled sooo... help me with a shopping list? This would all be from a plug source. Im no electrician. I can do simple wiring but thats about it. Thoughts?

TRIAC dimmer driven by a slow ramp oscillator is the first thing that comes to mind. You could use a simple 555 timer for the oscillator but if you're looking to mimic variations with seasons you're gonna need a microcontroller. I can't say how well this effect will realistically mimic a sunrise, probably not very well, but it should at least create a gradual ramp in light output which should at least mimic the effect in the most basic sense.

More realism is more an issue of optics than electronics and for that you'd probably want an array of lights and you'd want to match the color spectrum close to that of the sun plus compensate for how the atmosphere will distort that as the angle of the sun changes. That's a massive rabbit hole though and would make this project extremely complex.

not bad. course if only this had the proper bulbs in it. maybe I could rewire it. And sorry m8 I never come on here, so- yeah. I am dead set though. Sunrise simulation might be good keywords in retrospect though.

>>1594299
smart- but doesn't tackle the spectrum issue.

Do you think I could get a cheap manual dimmer switch and attach it to a dimmable daylight bulb and then have a timer unit slowly manually move the slider? my guess is that it'd be too weak, but I could probably remove a spring in the slider for instance.

this would require a reset daily if I didnt mod it too but this might be the most simple.

and you're probably right on the array of bulbs for realism, but yeah I just wanna go basic for the time being. I've bought some "daylight " bulbs in the past and they're nice for lighting in general so it'll prolly do for now til I get a little more informed and build something really nice.

Online you can find the rgb
and intensity values for empty sky. Then also the values for the sun (color temp and intensity) at morning, noon, and evening.

Then use rgb LEDs, lots of them. And a power supply and microcontroller.
>>
>>1594978
This is similar to what I did in a way.

In the living room I have recessed and hidden ambient lighting. I have three strips of it. Daylight, Warm, and Ultra Warm.

Each of them has their own controller which takes in a 10 bit signal for PWM. And there's an Arduino brainbox. As the evening progresses it will transition from the Daylight, to the Warm, to the Ultra Warm and then slowly dim that UW to 10%.

Having the interior light mimmic whats going on outside has definitely helped improve my sleep pattern.

The part that impressed us most was the nightly bedtime struggle sort of dissapeared.

i've never created a sewing pattern before but im trying to create a cosplay of ghiaccio from jjba. i made this on illustrator and can have it printed in actual size on paper at my job. I would like some feedback on if this looks usable or not.
>>
>>1595531
Pattern making for clothing has some little idiosyncrasies that you need to learn for well fitting articles.

Go into the fabric stores and browse the catalogue. Find something similar in general fit and function as what you want to make.

Don't cut up the pattern you bought. Trace that onto vellum or newspaper, or something else and cut that out. That way you can re-use the pattern over and over for multiple sizes if you make something for someone else.

Pay attention to where the darts are, and where things are taken in. Getting familiar with these will make creating your own patterns easier.

You definitely can power wash the moss off but depending on how old and brittle it is you might blast off pieces of your render too. You can always patch those up though.

How do I remove this goddamned castle nut? I've tried using a Dremel, using some nut splitters and I've also cursed at it. The bolt spins only enough to move it's position but it won't go up nor will it tighten. I am doing this in an apartment parking lot because I'm too damn poor to own a house and garage and I have basic tools for oil changes and a set of ratchets from Stanley. I want to remove the damned nut off but I don't wanna be evicted for using torches or making to much noise. Please help I've been trying now for what feels like a month trying to remove it but it won't come off like a damned parasite.

I've been given a camper by a relative who's encouraged me to renovate it. I build furniture, so I'm not a stranger to diy stuff at all but I've never worked much with trailers. It's already been gutted and the walls are practically falling off but the trailer frame itself is in good shape, just slightly rusted. Where's a good place to start with it? I'm pretty sure I can build up the walls once I get the wood frame onto the metal but I guess I dont' know how to get started or even what to google.

First time poster looking for some advice. I want to make a rowing bicycle.
I was inspired by this german engineers attempt www.rowcycle.de, but it's
not for sale yet and they say it will be priced in the mid 4-digits -
way outside of my budget. This american version rowbike.com looks way less
complicated but also not very interesting.
I plan to make it mostly out of recycled bits to save on cost. I've got
some understanding of mechanics but no real engineering experience.
I've got basic tools and can get used bicycles for next to nothing.
Looking for ideas and technical help to make a rowing bicycle.
Some of the things I expect to be difficult are:

1) Converting pulling motion into rotational motion.
2) Having the pulling handle return to starting point without creating too
much resistance that doesn't convert to rotational motion.
3) Decoupling wheel motion from pulling device when not actively pulling

Why not use a torsion spring? They're compact and do exactly what you want.

Use a sprag bearing. They are available cheaply online.

>To avoid the need for a differential, i think it's best to have the driving
force on the single wheel end. What are advantages/disadvantages to having
the propulsion wheel in the front vs back?
I'd say you're right about avoiding the differential by using a single drive wheel. In my opinion you should use a rear wheel drive set up, front wheel steering, and brakes that are either rear only or heavily biased to the rear. Also, the brakes should be applied by a hand lever positioned next to your dominant hand. Lastly, regarding your steering system, you would be best served by a foot pedal operated system. My first thought is that you should have a pedal arrangement such that you can steer with either foot while bracing with the other.

Alternatively, no steering and no reverse.

>>
>>1595501
It is a terrible personal vehicle but it is a good way to get some miles in if you can travel around in it (you wouldn't be able to most places). The main issue is that you're so low down and in most places you'd be expected to ride that thing on a road with automobiles, so scary shit and also fun inhaling exhaust fumes. Not impossible but not great.

The steering is not the problem really, people doing sculls steer with a foot mechanism in the boat so it's a bit of practice in a way, easy enough to set something up. Also while rowing is more upperbody than cycling, it's still very leg dominated.

Hello.

As a project to make things more beautiful I have decided to breed local butterflies.

The reason for this is yesterday while I was planting strawberries, a large peacock butterfly came and landed on the patch and sat with me for a good 30 minutes, only to move to a window and sit for most of the afternoon.

It was a very spiritual experience and prompted me to firstly discover it's type, which I have not had the pleasure of seeing before - but also the desire to breed them for release.

The larvae are relatively cheap and these particular butterflies thrive on stinging nettles. Some varieties of the exotic prefer rotten fruit and citrus - however these will bring havok to the locality so can't be released.

A few monarchs have found there way across the ocean but we don't produce milkweed here.
