any of you that have made heatshields sans welding, do you just use sheetmetal? multiple layers? sheetmetal-thermalwrap/sheet-sheetmetal sandwich?

i want to make one to isolate the turbine/downpipe from the radiator/alt/oil filter (around 1" between alt/oil filter and 3" downpipe) but don't have a welder around, so figured some combination of trimming and bending sheetmetal would be my best bet
JET i assume you've made some, any ballpark on what you'd charge for something a bit more polished? (assembly-wise, not shiny-wise)
