Plastic Vs. Metal Dust Collection
So as to not hijack other threads I wish to ask a question. Everyone seems to believe that plastic is cheaper to install than metal. However I don't believe I have ever seen anyone post the actual numbers. Has anyone really run the calculation?
Here would be my assumptions for a garage shop system. Trying to keep it simple so it isn't a major effort to calculate. If you have already run the numbers for your system post these instead.
40 feet of straight pipe either snap-lock 6" metal 26 guage from the BORG or 6" green plastic pipe.
Fittings to make 8 90 degree turns in the 6 inch pipe, either long radius metal or using 2 45 degree plastic and a small piece of straight.
3 Wye fittings
Hangers as needed say 10.
Primer/Glue for plastic, or metal tape for metal.
I am going to ignore the cost of adapters from 6 to 4 inch pipe, blast gates, etc. since this could be interchangeable.
Cost from Spiral Manufacturing

A quick call to Spiral Manufacturing http://www.spiralmfg.com/ yielded the following...
40 feet - 6" 24 gauge spiral pipe - $11.36 / 5' section = $90.88
8 - 6" dia long radius die stamped elbows - $17.92 / ea = $143.36
3 - 6"x6"x5" tapered reducing lateral (wye) - $35.71 / ea = $107.13
4 - 6" male couplings for connecting pipe sections - $1.86 / ea = $7.44
Hanger strap and duct sealant not figured.
Total cost - $348.81 + shipping to your corner of paradise.
