Topic tags/keywords: trick tip jig shopvac

I would like to fit my shopvac with a plastic bag liner. Without some type of device to hold the bag against the inside of the shopvac I find the bag everntually sucks up around the filter and suction stops.

Any ideas for a simple device which I could remove, then remove the bag, put in another bag and reinsert the holding device and start again?

use hardware cloth (wire with squares welded in it to make it appear like really coarse screen). cut it to about 1” from the bottom of the inlet and use enough of it to equal the circumference of the vacuum. put it in the bag and slip the bag in the vac. When it’s time to empty, pull out the hardware cloth to use with the next bag.

I have been useing a shop vac brand vacuum for many years and use the bags made for that vacuum without any problems. I have never had one come of the only problem that I had was when I forgot to change the bags I remember to change the bags now. A pac of bags cost about 10.00$ for a pac of three I hope this helps

I read a tip where you used a regular trash bag, held on the top with a strip of plastic laminate like you would use for a counter top. I guess any thin strip that would fit in the vac and create a ‘clamp’ effect would work, like a piece of matal with a bit of ‘spring’ to it.

I’m with Dave, I’d just throw a chunck of something in the bottom of the bag. Eventually, as it startes to fill the weight of the chips and dust should hold the bag down and out.

I put a bucket inside the shop vac and the plastic bag inside the bucket. Works.

I have used the shopvac brand bags in my shop vac, especially for drywall dust and the like, they are great. They act as another filter so the shop vac does not blow the dust back out. As mentioned though they are a bit expensive.
I will have to try the plastic bag trick, sounds much better than trying to empty the can, that can be a real pain.
