Years ago I built a dust collector network which tied my 10 stationary tools together using the old style drum and bag model Delta 50-179. It has served my purposes for years, but now the motor caught on fire and is a goner. I checked into a replacement and Delta wants nearly $900 JUST for that motor alone! I don't think I paid $400 for the whole unit! Revamping my network would take some extensive remodeling so I'd like to salvage the old 50-179. I believe I can buy a comparable motor for like $200 which I'm willing to do, but now I wonder if that would be throwing good money away. Has anybody made the same replacement? Any recommendations would be appreciated!
