Topic tags/keywords: question sander sanding


I am about to wrap up the construction of my shop build thickness sander (thanks to Blake) and I was wondering, for those of you with thickness sanders, would you prefer to use a shop vac with a filter bag installed or a dust collector?, I have both, my thinking is that the dust is so fine coming from the sander that it would not settle in the main bag of the dust collector but clog up the bag that filters the exhaust. I hope that makes sense. Im just wondering which type of vac to use, i could mount a shop vac under the sander for convienience. I will post pics when I am done and many thanks to Blake and Yorkshire Stewart and the other LJ’s who have made these sanders, looks like it is going to work great.

P.S My dust collector has a 1 micron bag for the exhaust, My shop vac is a standard one with the yellow filter bag.

I would think the dust colllector would be the way to go. The shop vac is not create enough CFM to effectively collect the dust. Depending on the size of the sanding drum and what grit paper I have read that you will need about 400CFM to collect the dust.

i can tell you now from experience that a shop vac is not enough to pull the dust from a drum sander. You definately need better than 750cfm. My van did a little less than ok. my dust collector pulls 95% of the dust and also allows the paper to live longer since it doesnt fill with dust and burn. Hope this helps a little
