The proper way is to have the channel cut safely and completed as intended. I have cut them with a plunge base and on the table. Both have pro's and con's but both can be done safely and accurately. I googled your router and it looks like it has a dust collection adapter that attaches to the base that would be on the router when under the table? Put/screw that clear plastic piece that has the dust collection port on it to the base and have it connected to a vacuum. that will help with gathering dust near/under the bit while your above table dust collection can collect the dust from above. That will help with dust collection to a degree. One of the con's to the table method is sometimes/often the dust collects in the groove you are cutting. If you use the plunge router method you have to have dust collection at the bit for any hope of not making a dusty mess.My question: Is there the proper way to cut a T-track channel in a table saw/ miter gauge sacrificial fence board ? How should I setup my router table for proper dust collection for this? The dust and debris was flowing/flying out to the left, channeled out by the very slot I was cutting.
Routers make a lot of dust and sometimes you just take the piece outside, let her rip and go back in the shop.
