Construction Tools

The flat chisel is a popular woodworking tool, for cutting and shaping wood

A chain block is a device where a chain runs through an overhead steel pulley block and can be used to lift things and be locked into place. A very useful tool .

Most probably yes. I have known of Komatsu operating through a large local distributor. I am sure even Volvo would have some similar way of operation. All of these leading construction equipment dealers are 100% representatives of their principals. They have strong supply chain network and excellent back office support.

Diamond by nature is the hardest material, therefore Diamond bits are the "hardest." They are only for ceramics though, for drilling in metal, you would use a cobalt, or carbide drill bit.

"chuck"

That's an 'opinion thing', like "are Chevy's better than Fords" , but I honestly believe Nicholson files and rasps in general are VERY good products and I consider Benchmark average.

I believe that it was made in china, but I'm not sure when. The gunpowder that they recently made was put into a bamboo pipe, stuffed with rocks on the top, and lit from the bottom. They called it: The Boomstick

Cobalt Drill Bits Ideal for drilling into hardened steel.

you can't buy new ones

Both will. Carbide tips will last longer but the black ones will also. The key is to run the drill slowly and use oil.

A small bent chisel for wood carving.

You cannot use any type of "engine oil" on a chainsaw bar. Even though the oil itself is quite adequate, manufacturers put a tackifier into the oil so it doesn't fly off the chain when in motion. The temperature outside is irrelevant, in this case.

First, lets qualify the term "Fire Blocking" vs. "Draft Stopping" Fire blocking is a term commonly used to describe the blocking used at the mid span of a wood framed area to inhibit the advance of fire within a concealed space, thereby maintaining the structural integrity of the building during a fire. It is described in the building codes (IRC/IBC) as follows: FIREBLOCKING. Building materials installed to resist the free passage of flame to other areas of the building through concealed spaces. Fireblocking is seldom required in residential construction any more (there are some exceptions), however there is a process called "Draft Stopping" that is common in all wood framing and used extensively in residential construction. Fireblocking is most commonly seen in fire rated assemblies (walls, floors and ceilings). It should be made of noncombustible materials or a rated assembly that incorporates combustible materials (rated assemblies have been tested and are built to very strict standards). There are some applications that allow standard dimensional lumber (such as 2x4's) to be used. Check with your specifications or code requirements in your area for clarification. Most can be placed using standard forms of attachment, such as nails, screws or staples, and some require special attachment processes. If special attachment is required, it will usually be spelled out in the design specifications (see you plans and details or assembly specifications). Draft stopping is described in the building codes (IRC/IBC) as follows: DRAFTSTOP. A material, device or construction installed to restrict the movement of air within open spaces of concealed areas of building components such as crawl spaces, floor/ceiling assemblies, roof/ceiling assemblies and attics. Draft stopping is required to be located in areas where a transition from horizontal to vertical or vertical to horizontal occurs. It is also required in spaces over a prescribed volume or square footage to limit how much air is available to feed a fire. The intent is to starve the fire of oxygen before it can grow to a point that it can cause severe damage to the building or structure. As draft stopping is used to limit air and not stop fire it can be build of almost any material approved by the building codes. We commonly use sheet metal, wood framing members, insulation or expanding foam for draft stopping. In Conclusion, it would be wise to determine what you are doing and which process you are required to use. Then, call your local building inspectors office or design professional of record and get approval for the application. Hope this helps! Terry

A sensitive drilling machine is an upright drilling machine. However, a radial drilling machine is also considered a sensitive drilling machine.

Because it depends on gravity to work. -Gravity doesn't work horizontally .

You turn the key as hard as you can.

You would want to use a 1/2" drill bit IF DRILLING FROM BEHIND THE AIR RESTRICTOR. If you drill from the front where the dart sits, you can wear the plastic inside the barrel, resulting in air slipping between the dart and the wall of the barrel. Not good. If you want to be on the safe side, use a 1/4" bit.

Very large load haul dump trucks Used in mining have a huge diesel engine that turns a big generator. The electrical power from this goes to a big electric motor in each wheel.

It is the angle between the cutting edges.It is usually 118 degrees

The first axled wheel carts used solid wood wheels with a square box on top. Spoked wheels became widely used for transportation (wagons and carts) but solid wheels were sturdier for wheelbarrows and are still used today.

Your local lawnmower and gardening tool store would have that, or be able to get one in easily.

most chainsaw gas/oil mixtures is 32/1

a good way to remove a metal bolt is to get a screw extractor. You drill a small pilot hole down the middle of the bolt, and lightly tap the extractor into the hole. The bolt will then twist out. You may need to add lube to the bolt if its rusted (WD-40 etc.)
