How Loud is a router?

[balsaman]

I think most of the noise is vibration and brush noise. It's the shear speed at which it turns. Cutting noise is a huge factor as well. Like I said, come up with a quiet high speed spindle..you will be rich.

Kong, don't let me discourage you, give it a try and let us know if it helps. I am just guessing and thinking out loud. Maybe enclose the thing in an insulated cardboard box for now as an experement.

I have a old 3 1/2 hp Porter Cable on mine and its very Noisy. Its in my attached shop about 30' from the living room. I had sense enough to put a 6" insulated wall between the Shop and house.(all one building). And a exterior door. I can sit next to the door and watch tv at a regular level with the router the 2 1/2 hp Shopfox vacuum system and the 3 hp Vacuum pump going.
Now when I open the door and enter the shop I reach for my ear muffs..
I have a Friend that has a 5hp spindle on his machine and its 5 times quiter than mine. But the spindles are $1500.00 also. And his Vacuum is a 10 hp Rotary outside in a insulated shed.
Sound is a big issue. Insulation is a big help. Dust is the next thing to conqour. That 2 1/2 hp vacuum is not enough. I have two rows of horse hair brushes around my router but it still spits the chips. And if cutting mdf the dust is terriable. I did build a filtration system for the shop air that helps some with the fine dust.

I had a Kress router on my machine. It was the 1.25 HP model 8000-25000rpm and it was very quite, even at the highest rpm setting. (quiter then my dremel tool)

I had problems with it and found out that that model was discontinued. They sent me the 0.75 HP model as a replacement (I was still under warrenty). The .75HP model would be a good choice for a quite router, but I didn't want to give up the power.

I now have the Porter Cable 1.75 HP model. Like other posts said, its quiet at low rpm, but screams at high rpms.

I have a need for a small hp router. Where is the best place to order a Kress from in the US?

I remember when the spindle on the multicam router at work went. The replacement came with an electric fan instead of the one attached to the shaft. The reduction in noise was astonishing. I cant remember which spindle it was, but it was around 1300 bucks.
The spindle on a large mill is almost silent. I know they are running in the 3000 to 5000 RPM range, but why not run a belt drive with 1 to 3 ratio and quieter motor with more torque and less RPM?

I got my Kress router from Techno Inc. , 516-328-3970. (located in New Jersey)
Its a well made router, but its not cheap. I think it runs around $360.

I have no experience here, but I have seen some of the industrial spindles are water-cooled. How does an induction motor work differently from a brushed motor?

wjbzone,
Thanks, I'll check it out. That is a little spendy but worth it to me if it is quiet enough, ... got close neighbors.
