Makita 7.2V Drill DF012D: A Low Power Screwdriver for Pros | 1" Check Valve

I’d like an official Hackaday PVC Safety Police badge. I feel that I’ve earned it. But don’t actually make the badge out of PVC, for safety reasons.

On products like knife blades, manufacturers coat the blade before putting on a final edge. This reveals that silver edge on brand new blades. Conversely, a drill bit gets its chemical bath last. You actually see the coating over the cutting edges when brand new. Use that bit or sharpen it with a Drill Doctor, and the natural uncoated edge shows through clearly.

So why aren’t we all driving camless engines? There are a few reasons. The advantages of camless engines to camshaft engines are analogous to the advantages of electronic fuel injection (EFI) vs carburetors. At the core, a fuel injector is a solenoid controlled valve. The fuel pump provides constant pressure. The engine control unit (ECU) fires the injectors at just the right time to inject fuel into the cylinders.The computer also leaves the valves open long enough so that the right amount of fuel is injected for the current throttle position. Electronically this is very similar to what would be required for a camless engine. So what gives?

The winner advances to Saturday’s quarterfinals against the winner of the game between D4 champion Loyalsock (27-1) and D12 third seed Bishop McDevitt (19-7).

It’s also true that heart attacks in males and females may, even frequently, present differently as far as symptoms. But this knowledge is known in medicine. It’s precisely because of science based medicine that we know crushing pain is sometimes absent for females compared to males.

That mattered little to Bavaro, the soft-spoken but bone-crunching end who was regarded as one of the toughest players — not just at his position, but among all players — during his time in the NFL. He delivered crushing blows to defensive ends and outside linebackers when the ball was handed off to one of his teammates or when he was assigned pass protection duties.

Bosch makes some pretty big claims about their bits. But Bosch has a solid reputation in the concrete industry for good reason. When they make a claim, they usually back it up on the job site. A design that allows for longer runtimes and more precision in applications that tend toward the destructive end of things, well, that sounds pretty good to us.

The Milwaukee Step Bits tracks very well at the beginning of the hole and leaves it virtually burr-free. There’s very little of the annoying and time-consuming de-burring on any of the holes, even as that smaller size starts to show its wear.

Finally, WRT to legislation: what would the motivation be? switching from carburetors to EFI dramatically reduced hydrocarbon emissions and, with them, smog. What public good would we realize with camless engines? Most car engines spend most of their lives operating in a very predictable, narrow band of operating conditions, so optimizing camshaft profiles for that scenario is not a big deal. I don’t see any major efficiencies to be gained from camless engines. Generators similar diesel-electric systems run at even more controlled speeds/loads, the whole point being to maximize efficiency, so the benefits of going camless for them would be even less.
