Default shop vac - how powerful

may I ask if anyone has a chart of vac performance figures in relation to each power tool. eg. how many millibars or KPA of pressure and how much air flow are required for a sander for instance.

I've never had any trouble with a shop vac and any hand tool. My first table saw had a 2-1/2 inch port for a shop vac, and it did OK, but not great.

I have a large and small one as well as a 2hp DC. The small did a decent job with the last model of router table I had. It has about a 1 1/4" hose on it. It will hook to most of the small power tools I have like sanders and biscuit joiner. It does okay with the sanders and helps with the biscuit joiner. I haven't tried it on my one router with a dust port yet, a Hitachi M12VC. It should make a difference with it too. The larger one is hooked to the new router table and it does a little better. It is still too small for my stationary tools.

Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.

Shop Vacs have never been a good solution in my shop. I have one of the large ones and have never been satisfied with on a tool. I've finally gotten a setup that works for me, using a 2 hp HF unit. I got two on sale, one for the garage where my planer, band saw and jointer live, the other for my small shop. The shop unit has a canister filter, the one in the garage just uses a bag because i can roll it outside when in use. Both use flexible 4 inch hoses and both have a 30 gallon chip collector inline as well. Before that I'd cobbled together a home brew DC, but was never satisfied with it. With all of that, I still wear a mask when cutting in the shop, and for some time after.

For small tools, I have a 2.5 inch hose with reducers if needed on one end, and an adapter to 4 inches on the other. I just drop the adapter end into the DC's connector when I need it.

Sawdust is very bad for your lungs so I suggest you consider getting a real DC system rather than spending money trying to cobble something inadequate together. By the time I got my home brew system working OK, I'd spend nearly as much as both my HF units ($ 187 in sale with 29% coupon at 2 separate stores). I was able to use the 30 gallon fiber drums from my old setup, which saved some. I had throat cancer years ago and I just don't want to mess with sawdust.

Although I understand about budgets, once my wife understood what's at stake, she insisted I get the good stuff.

I have a Fein Turbo shop vac. There is a valve on the end of the hose to turn down the pressure when using hand sanders. The shop vac works much better than a bag when using my Bosch 6 and 5 inch orbital sanders. But I find I need to reduce the suction when using the Bosch sanders for it to work best.

I have a Ridgid shop vac "the large one". As someone said on here it will suck the chrome off a trailer hitch. I use ir on all my hand power tools plus my router table fence. The Ridgid vac works great. For larger tolls like the table saw I have a Grizzly 1.5 HP dust collector.

Measure once cut twice and it's still to short.

I'm with Don on this combo and find it works very well. The one downside if it is one, is that on connecting the shop vac to my Bosch 5" ROS, if the ROS is on the board when I start the shop vac it will cause the ROS to adhere to the board. An excellent reminder not to start the ROS in place.

I would not recommend the shop vac for any stationary tools, particularly not a planer but it works well on the chop saw.

I also added a HIPA filter to the shop vac and with the muffler provided the system is relatively quiet.
