   A small shaper that has collets for 1/4" and 1/2" routerbits will do. It would be tough to build a router with an induction motor, too heavy and bulky. Most will have top speeds of 8000 to 10000 rpm's. Jet and Grizzly have them as I am sure other manufacturers.I have no idea what the decibel rating would be compared to a router.How about sound proofing your work area? If it is feaseable , go to a wallboard supplier ( not Lowes or Home Depot  or lumber yard) they will supply you with information and materials to do the job. If you go this route you can email me if you have questions, also go to breaktime and you will get  a wealth of information on soundproofing.

   You could look at the Onsrud inverted router or an overhead pin router as an alternative.

     I think mike was right. an induction motor weighs more than double what a compairable  universal motor does. Have you ever picked up the motor off your TS? My 1 1/2 HP contracor saw's motor wieghs as much as 2 3 horse routers. Then theres the speed thing. Your best bet is to get a shaper, though you will not be able to use many of the bits you have at the slower speeds.

   Ragman,

   Although universal motors are noisier than induction models, most of the induction motors used in typical woodworking shops operate at relatively low (about 3450 rpm) speeds: a mere fraction of the speed at which most routers operate.

   I'd be curious to know how much of the noise generated by a typical router emanates from the motor, and how much is contributed by the cutters chewing on wood fibers. In other words, if one were to employ a quieter induction motor, what would the measured sound presure levels be once the cutting commenced?

   Anyone have a sound pressure level meter handy and feel like conducting an experiment?

   -Jazzdogg-

   Whether you think you can, or you think you can't, you're right.

   I have an overhead pin router and it has an induction motor but uses a belt and pulley to get the 20,000 rom from a 3450 rpm motor. It's not much quieter. Just a different pitch.

   The German manufacturer SCHEER makes and made a lot of induction type machines. On this moment they no longer make routers but on the secondhand market jou can take you chance: e-bay deutchland

   Thank you all for your suggestions. I can afford to get overhead pin router in terms of space and usage. I think i'll go the soundproofing route as suggested. My router table is already box like. I don't thingk that there is anything iwe can do about the noise when the bits bite into the wood but at least when the motor is on and i am not cutting the work, it'll help to cut down the noise. I'll post my results when i finished with the sound proofing. I am bearing in mind that within the fully enclosed box, i would need to open the door often to vent off the heat build up.

   I additon to what I suggested: E-bay Germany this evening.
