Take a look hereCONGER":93h0h2ta said:Whisky.... I see you are using a cyclone on top of a blue drum.
I guess that this is one of those watertight drums we see used for rafting?
I used exactly the same configuration.... the drum was a quality(?) version.
The idea was great... but.... when the vac tube blocked (e.g. sucked on a large piece of wood... or...) the drum collapsed... totally!
I straightened it out again... and placed a ring 'corset' inside the drum.... and it collapsed again... just more 'elegantly'.
What did you do to avoid this?
BTW... I got a mild steel paper bin.... and now all is fine. The vac (FESTOOL shop vac) will pick up anything... I have to check my fingers and toes.
