Exactly what do you think a thermostat even does?

>I said in the OP to not worry about it

No, you didn't. You said "not to worry about sheer forces". One, I think you meant "shear" and, two, what I described is not a shear force.

Anyway, assuming you've got the thing fixed to prevent it from falling sideways, >>1598824 is the least death-trappy death trap you've posted so far, by a longshot. It's actually almost passable for a decent design, if you squint hard enough.

...you're...kidding, right...?

Gee.

Other than it probably being an unlivable shithole in its current state, of course.

You don't like dildos?

What are you, some kinda faggot?

>caps suck at providing quick stable power

That...that's the entire point the point of putting a filter capacitor in a circuit, and why you will never see a railgun (which demands much higher power than a coilgun) of appreciable size run off anything but a large bank of pulse-rated capacitors.

You can get away with using other power sources in a coilgun specifically _because_ the minimum power requirements can be lower. But then you also have to account for actually switching off the coils, which, in higher-powered guns operating at hundreds or thousands of amps, is not necessarily trivial.

For projectiles, just buy some steel rod and cut/grind it to size and shape. It's cheap and should be plenty straight.

What the fuck is this shit? This is not at all reflective of more typical hardwood prices, at least not exotic hardwoods. The more expensive "building" hardwoods at my local lumber yard is like $15/bdft.


Actually, I just looked at that link, and you officially have no idea what you're talking about. Prices are listed in "BF", which is board-foot (bdft). A board-foot is 12x12x1", or 144in^2. And only their most expensive hardwoods (and, naturally, their exotic imports) go above $16/bdft. Most of them are only $5-9/bdft.

And 48% of that thing is fucking wood? How the hell are you assuming nearly half the containing volume of that thing is solid wood when somewhere between a third and half of it is EMPTY SPACE? And what, you think that upholstery is just pulled taut over solid wood? No, the inside is going to be a mostly-hollow frame with maybe a box spring supporting the middle area. Even if we assume that the outside is as thick as the borders imply (it's almost certainly not, and likely only half that thick or so), I'd be surprised if the hardwood occupied more than about 8% of the total volume.

So, let's see here, I'm not going to bother to check your math, so I'll just divide your final figure up.

$105,600/3 (to correct from linear feet to board feet) = $35,200
$35,200/2 (to roughly correct that you used a figure about double what typical hardwood prices are) = $17,600
$17,600/8 (to roughly correct that your estimations of volume are way off) = $2,200

$2,200 is a much more realistic estimate, although it still intuitively feels a little high for what I'm looking at. Depends a lot on exactly what wood and lumber size you use, too. In any event, I can only suggest you never look into actuary work, because you'd be fired before the interview was over.
