Ok ok... So not trying to spark off anything here but... I have a Harbor Freight dust collector #45378. Hey it was what I could afford at the time, like some others I paid about $159 for the unit, and well it is what I own now so... ignoring it's general lack of quality I have a question about replacement bags for it.
After searching on here I found that basically everyone replaces the bags that come with. After reading this I decided to look at them closely and I must agree those that came with it are pretty bad stuff. The gaps in the weave are pretty darn big. So I went looking for the shaker felt replacement bags at Highland as many seemed to like those and then realized I had a problem.
I am left wondering what size bag do you buy to replace them? Does anyone recall?
I measure my unit and doing a rough measurement across the metal center band appears to be about 19.4" across. There are 2 bags that flank that measure an 18" and a 20". I am just wondering which ones fits better?!!? I am not sure if it better to have to stretch it to get it on or if being a little loose is the way to go and then you use the metal strap to cynch it down?
If anyone has done this and you remember what size you bought it could be a really great help to me! Again, just in case it helps I have the 45378 dual bag big DC unit.
Also... I have seen in some photos a plastic bag on the bottom of it. Which seems like a good idea. But I am left wondering if anything needs to be changed to get that to work? Is a larger bag, a smaller bag or a different kind of bag altogether needed in order to make that change? And I suppose a question I should have asked at first. Does it help and make a difference?
Thanks!
