200Litre (50Gal) Vacuum Cleaner Pre Filter / Drum

I found that while I could physically put a lot of it into bags with a dustpan, there was always going to be little left overs that wanted vacuuming, but I would always fill up my vacuum cleaner back in seconds. So to give me more vacuuming capacity, and to put a large drum vacuum into my shop I experimented with cyclonic bin vacuums a bit before settling on this. Its really simple design and was made out of cheap things.
