My wife got me a dust collector from Harbor Freight for my birthday and I decided that i wanted to make it a two-stage system. I bought a trash can cyclone lid from Woodcraft and a new trash can from Lowe’s and added that as the first stage for the system. The thing is, it seems like most of the dust and chips are going straight through the trash can and straight into the dust collector bag. Any ideas why this is happening and/or how I can fix it?
