Near the end of the bit is a vacuum port. It allows the bit to turn while the hose stays in place. Bosch’s dust extractor hose nozzle is already a perfect fit, so it works well here.

You’re right, quick exhaust. A Fernco 3in pipe cap (rubber) works well up to about 100psi. Higher than that the pressure differential caused it to oscillate and not release fully.

NSF’s lead leaching protocol[4] for fixtures like faucets involves a 3-week evaluation using water that is more corrosive than the average drinking water but less corrosive than water from some parts of the country.[5] The more corrosive the water, the more lead will leach from the faucet.

Bosch has a line of hammer drill bits designed to last longer and drill faster, more precise holes in concrete with rebar. The Bosch Bulldog Xtreme Bits have a conical, 100% full-carbide tip with an upgraded variable flute design. The end result, Bosch claims, is an SDS-Plus bit that provides 25% more holes drills per charge and rounder holes for more precise anchoring.

First, determine whether you can move the hole to another location or drill a shallower hole. If neither is practical, switch to the next heavier rental drill, called a rotary hammer. Get a masonry bit and a rebar-cutting bit. When you hit steel, back out the masonry bit and install the rebar cutter. Switch the drill off hammer mode and into drilling mode, and drill through the rebar before backing the bit out and switching back to the masonry bit and hammer mode.

Suprised the author missed this. The valve actuators are there on this design, albeit for only half the valves. It shows a relatively simple design which does not require a large complex hudraulic setup. Possibly a high pressure common rail with an accumulator to work. The pump would have to be able to keep up with the demand.

I also find the 10-year / 100,000-mile timing belt replacement to be fairly reasonable. It only takes a few hours to do, only happens once a decade, and presents a good opportunity to replace the oil and water pumps, etc., while you’re in there Of course, I’ve also had an engine with a timing chain destroy itself too (with the chain wearing the tensioners, coming loose, then slapping the water pump.)

Numerous people chimed in about their theories about how vaccines may have played a role. Some people suggested that he might have recently received a flu vaccine. Since anti-vaxxers are super good at investigating their claims, one person provided a source for the link.

Tighten the chuck up so the bit can’t move without removing it so the adjustment doesn’t change. Then pull the chuck out and give it a little extra tightening. Just be sure not to overtighten it – the goal is to make sure the bit doesn’t move during sharpening, not make it a permanent fixture with the chuck.

The inside door panel on this apparatus is equipped with a full height stainless-steel panel, LED warning light and angled handrail. Note the red color webbing over the door strap, which can be used to assist personnel entering the crew cab area.There are different options for valve controls on the front intake, including an external manual butterfly-style, air-operated and electric actuator controls. Each style of valve control has advantages and drawbacks; however, if an electric actuator is preferred, then specify an easily accessible manual override to enable the engine chauffer to open the valve in the event of a system failure. One of the principal missions of the engine company is to rapidly secure a reliable water supply and whether this entails having the first-due engine apparatus lay a supply line or hook up to an available hydrant. Well-designed engines should be able to bring in a water supply from several positions on the apparatus to ensure an adequate and reliable water supply. 

Safety should be paramount in any portion of the vehicle design, and this should start with a review of access to the cab and body compartments. All step surfaces should be provided with aggressive, non-slip surfaces, and depending upon your local weather conditions, may require more than the standard raised diamond, aluminum tread plate. The position and location of handrails should be determined, including areas inside of the cab, to enable personnel to maintain three points of contact at all times.
