I didn't want to intrude on Kevins topic he started about dust separators recently, but I have a question. I have been using a Home Depot Duststopper on a 5 gallon bucket for quite a while and it appears to work pretty good. Yesterday I got to thinking about it and I also have a small Dust Deputy that I purchased several years ago. I found it yesterday and decided to put it on my bucket and see it I can tell any difference. With the Dust Deputy, after running it a few minutes, it collapsed my bucket on three sides. It also appears I have a lot more suction at the saw. That is a good thing, but I am somewhat concerned about what it is doing to my vacuum. It sounds no different, but something different is happening and I cannot afford to ruin my vacuum. Amy one have any insight as to if this is a problem or not? Makes me a little nervous... I might add. When I first got the HD DustStopper, I mounted it on an orange HD bucket. It collapsed also, so I switched to this heavy duty paint bucked I had. The HD DustStopper did not collapse this heavy duty bucket.
