re: Can we talk shop vacuums

I spent some time yesterday looking into what was going on with my old Craftsman Shop Vac that was causing the motor speed to fluctuate.  At first I thought possibly a bearing was about to seize but, after spending some more time exploring, I realized that the hose just as it comes out of the vac was collapsing just enough to be the cause.  In an effort to fix it, I heated it up with the heat gun and then sprayed with some cold water to set it in a straight shape again.  Fixed it!  I feel kind of dumb starting this thread now but, in the posts that you all made, I learned about the filter bags which is something I have never tried.  I might have to give that a try.  I also learned about the Dust Cobra which is also on my list of things to look into.  Cool.  Nice bunch of folks on here.  Thanks to all for your input.
