Use a compass to accurately draw the hole. Bore a hole thru the sheet metal big enough to allow pointed tin snips to start cutting. Follow the line with tin snips until the hole is completed.

How do you calculate area in square meter of a duct elbow 45 degree?
To calculate the square meters of a duct you must add the total length of the straight duct work plus the loss of length from the elbows. A standard elbows measurement is 15 feet for each elbow with a 4 inch diameter or 20 feet for an elbow with a 6 inch diameter.

How do I patch 1 to 3 inch diameter holes in stucco?
Use something like Duct Tape to make a backing and fill the hole as much as possible with this. The use a putty knife to get the stucco material in the hole and to cover it, going up and down and side to side. You can then immediately paint over the patched spot, no need to wait on it to dry!
How many yards of concrete will it take to fill a 24 inch by 84 inch hole?
Concrete is reckoned by the cubic yard. But the hole mentioned only has two dimensions given - so I have to make an assumption, that it is an 84 inch deep round hole whose diameter is 24 inches. If this is the case, I work out the volume of the hole like this: volume of cylinder is pi times diameter times diameter times depth divided by four. 24 inch = 0.67 yard 84 inch = 2.33 yard So the volume is 3.14 X 0.67 X 0.67 X 2.33 / 4 cubic yards = 0.815 cubic yards. /BrianW

How do you repair a furnace duct?
Contary to popular belief, 'duct' tape is not for fixing broken furnace ducts. It was originally developed for sealing the joints between duct sections, and is a poor substitute for properly riviting the sections together. If you have a large leak in a duct section, you might consider replacing the whole section rather than trying to patch it. If the leak is only a few inches in diameter, cut a piece of sheet metal about the same thickness as the metal of the duct, drill holes 1/8 inch in diameter around the perimeter of this piece, and then lay it on the duct. Using a marker of some sort, mark a few of the holes at one end of the patch, and drill the duct with the same 1/8 inch drill. Using a pop riveting tool, pop rivet the patch to the duct. Work from one end of the patch toward the other, never drilling more than 2 or 3 holes at a time before riveting them. Otherwise, the patch will end up not aligning with the holes that you have drilled, and you will have to make more holes in the duct. If the patch must go over an irregular surface, like an elbow, you may need to use silicone sealant to seal the spaces between the rivets.Be careful when drilling the duct that you do not press hard on the drill, as it could cause the duct to collapse. If you do not have any of the tools needed to perform this repair, consider calling a heating and air conditioning specialist.AnswerIt depends on what is wrong with the duct. Could you be more specific?

Can a 31 inch tire go on a 30 inch rim?
No. The 'inch' figure for tires is related to the diameter of the interior 'hole' in the tire while the figure for wheels is linked to the outside diameter of the wheel. Trying to fit a 31 inch tire on a 30 inch rim would result in a 1/2 inch gap all the way around between the tire and wheel. Cheers
