I need a gore elbow or advanced flat-pattern formula in the field
Hold this as an advanced layout/approved-shop-standard question. Use the calculator page only for supported math; if a gore elbow layout is not provided for this job, verify with the foreman/shop before fabricating.
Watch out Do not invent a flat pattern from memory for field fabrication when the job needs an approved layout. Check Confirm duct diameter, elbow angle, number of gores, centerline radius, connection type, and available length. Check whether the shop/detailer has a standard pattern or calculator. Do a sketch with all inputs before cutting metal. Ask for verification before field-fabbing. Steps Confirm duct diameter, elbow angle, number of gores, centerline radius, connection type, and available length. Check whether the shop/detailer has a standard pattern or calculator. Do a sketch with all inputs before cutting metal. Ask for verification before field-fabbing. Say this to your foreman I need to field-layout a [diameter] [angle] gore elbow with [number] gores. What shop formula/template/calculator do you want me to use before I cut?
