This may look suspicously like Retired2's project. Mine has a 4" intake/outlet
I built everything out of scrap, except the seal and the acrylic. The bottom is made from 3/4" CDX, the sidewall supports from MDF, the baffle from 1/4" subfloor ply. The top is 1/2" BB over a sheet of plexiglass. The sidewall is 1/8" baltic birch.
You can view how I made my intake here: http://www.jpthien.com/smf/index.php?topic=1117.0
I purchased the plastic bellmouth from Parts express for $5 plus shipping: (Precision Port PSP-4IF 4" Inside Flare for Port Tube
Item# 268-377)
I added a 3/16" rod to support the baffel but after it started to capture lathe turnings I removed it. I think the baffel has plenty of support with the 3/4" ply support.
Works like a champ. Thanks Phil! (and Retired2). ;D
