Check out that difference, doing great so far. I can already tell from the deep pits at the end of the blade we aren't going to be able to get this blade to look perfect in the end. I would have to shave off too much of the blade and it would end up too thin. Oh well, let's see what we can do.

Hey /diy/. I was originally thinking of adding a friction drive to my bike for those times i'm feeling lazy. But I like my bike the way it is, so, how feasible is it to build one of these (specifically replicating that one wheeled hoverboard) and not have it be a gigantic deathtrap? There's some instructables that use arduino so it seems like it's at least possible? I get that for it balancing from front-back, but how about side to side? Also, IIRC the hoverboard pictured charges its batteries insanely fast (they're a lithium cell array, charges in like 15-20 minutes). How would I charge say a bunch of 18650 lithiums fast without it turning into the fourth of july?

>How would I charge say a bunch of 18650 lithiums fast without it turning into the fourth of july?
Liquid electrolyte lithium-ion round cells may be tempting for their somewhat better energy density, but if you're gonna push the charge rate past 1C/<1hr then you're probably better off with LiPoly batteries instead. I'm not saying charging round cells at 3-4C can't be done, but you're kinda in uncharted territory there.

Anyone here a car AC tech? This is driving me nuts, I have a 1999 Isuzu Rodeo that I've been trying to fix the AC system on for the past month and have already wasted so much money. Originally it had a weak AC that would only go could if I pressed the accelerator which I diagnosed to a weak compressor. Now I've replaced the AC compressor, evaporator, control valve and dryer and it's not getting cold at all. I've followed the procedure of flushing it out and then running a vacuum to boil out any moisture.

This is the readout on the manifold gauge,...

High low-side and low high-side is almost always a compressor but can be expansion valve. Check to see if anybody installed an aftermarket filter in-line those things fuck everything up (if they did it would be on the low-side before the expansion valve.

its the expansion valve most likely. this is what causes the compressed gas to expand into a liquid. if theres a blockage the gas cant expand properly and wont become liquid and thus wont get cold

Anyone try this brand of stain?Im staining,well trying to stain a set of new unfinished kitchen cabinets.The guy at Ace talked me into choosing Zar over Minwax and now im not sure if this was a bad call.Cabinets are red oak,nothing fancy.The stain in pic came out nicely whitish on a tester board of pine paneling.my problem is after 3 coats my cabinets arent getting much whiter.im just seeing more of the wood grain.does this stain suck?is it the wood?do i just need more applications?

It won't make the wood whiter no matter how many coats you use. It's actually making the wood grain darker. The same stain on a different wood type will show a completely different shade and color.
>>
To get wood lighter in tone the general methods are either Bleaching or Pickling
These techniques are NOT stains
They require a different set of products unlikely to be at a BIGBOX store
Try Woodcraft or Rockler
>>
>>950888
We have Woodcraft here but is it too late since ive already applied this to half the cabinet units?were not unhappy with the results so far its just...different from what we expected.the cabinets still look nice with our counter tops so idk if a ton of effort is really necessary if those lightening techniques would add days to the process.we have a lot more to get to by our move in date.

>Could I use a smaller one multiple times?

Technically yes, but it's not going to work as well. You simply aren't going to get as good a rub if you're trying to sort of "bridge" two flat areas with a small straightedge. Again, if you're bothering to scrape something, there's no point in half-assing it because the entire point of scraping is that it gives whole-assed results. Why spend hours and hours doing it if you can't get it to within a...

Quote from lowes compressor buying guide:

>The CFM value changes as PSI changes. As you lower the PSI output, CFM increases.

My compressor is rated 5.65cfm @ 87psi (160 l/min @ 6 bar). How do I figure out how much air it blows at lower pressure, let's say 3 or 4 bars?
