I have a Jet DC that I'd like to put in a corner of my small shop, and I can easily find many sources for 4-inch fittings to connect it to my tools (fittings, blast gates, hose, etc.).
However, what I'd really like to do is run 6-inch pipe from the DC along the ceiling, in a single line, with T (or equivalent) connections to 4-inch flexible hose drops.
The 6-inch pipe itself isn't a problem, as I can find what I need in PVC from Home Depot. However, I can't locate any source of parts so I can attach the 4-inch drops. I'm not talking about a 6-inch-to-4-inch fitting, which I can find, but something that would allow a 4-inch drop while continuing the pipe at 6-inches to the next drop.
Keeping the pipe at 6-inches as long as possible is frequently recommended, but I can't seem to find a way to do it. As I mentioned, doing the whole thing at 4-inches is straightforward, but sub-optimal.
Advice?
