Topic tags/keywords: question

I’m buying my first router table. My workspace shares one wall with one neighbor and I have another neighbor above me (I’m on the ground floor). My floor is poured concrete; the walls are whatever you call modern metal frame with drywall over it construction.

I want to be a considerate neighbor and so I’m interested in mitigating the amount of noise that travels to those adjacent units.

I haven’t bought a router yet, so lets start there. Is there any significant difference among models in terms of noise? One of the models that is directly compatible with the router lift I’m buying is the Hitachi M12VC. The manufacturer says it has “class leading noise level, only 79.5dB for a quieter workshop”. Purdue University has a noise comparison chart – it says a garbage disposal is 80dB.

Then there is the table. I’m buying the Incra unit, which is just an open stand.

I will enclose it by sliding in 1/2” panels.

And I’m also getting the Clean Sweep downdraft dust collection box.

Would the material I choose for those panels impact the noise?
Should I isolated it from the cement floor with a rubber pad, or would that not have any effect?

Any other thoughts?

Thank you, but what I am concerned about is noise transmission that might annoy my neighbors.

I built this. I enclosed the router motor. There is a 4” port on the left, a 4” veined vent on the right and a 2” on the top. Still noisy but better.

Wow – that’s a beauty! I’d like a bathroom vanity that looks like that!

The enclosure will help (get the bottom as well), as will that dust thingy. But they are loud, and I suspect since you have a dust box around they’ll be something else running. So it may be beyond what you want. Nature of the beast. The universal motors are loud enough on their own, but add in a cutter that’s spinning really fast and some sort of vac/DC, you’ll find it a lot louder than a garbage disposal.

THe top was from Rockler. If you want to learn how to build it, get the cheapest plywood you can get, some fairly straight 2×4s, a box of deck screws and get to work – add stain and poly to finish.

This is all cheap plywood, I keep it because it works and it reminds me that our shop cabinets are great places to learn how to build this stuff – make your mistakes here – not where others see it.

That’s a good point, Fred…there will be a dust collector, which is another 80dB.

David, I think you’ve got good taste and nice sense of proportion. I’m going to follow your advice. How did you attach the router top to the cabinet.

lets face it – the noise from woodworking machines (especially universal motor machines) WILL annoy neighbors :)

Figure 8s from Rockler.

I have a Bench Dog router table with a PC690 motor in it … noise isn’t bad … until the bit hits the wood.

There may be quiet routers, but I have never seen (or heard) them.

Routers are less noisy at slower speeds. On my variable
speed routers I usually run them slower than top speed
because 1) I’d rather route accurately than route fast
most of the time and 2) they’re not as loud.

Is the speed needed connected to the HP of the unit? For example, could a 3HP router route a board well at a lower speed whereas a 2HP router would need a higher speed for that same board?

If you are doing panels, 3+ HP is the way to go. Had a 2HP router and burned it fairly quickly.

You can feed the work faster at higher speeds generally.

With larger bits like panel raisers it is a good idea to run
the router slower because if you don’t the rim speed
gets really fast and may cause burning or other issues.
