Quoted from LynnInDenver:
Many of the Makers I watch on YouTube make miter saw stations that enclose the back half of the miter saw itself in a box, basically giving the saw enough room to come down (they have to move panels to do heavily angled cuts), and use the whole back box as part of the dust vacuum system.
The miter saw stations tend to include movable stop block rail systems, stuck on rulers, lots of surface to rest the piece being cut on, and storage.
Look on YouTube for Jay Bates and Jackman Works, both of them have built miter stations on their channels.
Love Jay Bates "Ultimate Miter Station". I even picked up his plans for it. However, I ultimately decided to make my miter station mobile. Plus, I didn't want to dedicate that much floor space to a single tool. I've learned that a workshop is always evolving, so everything in my shop is mobile. This makes it easy to move stuff around as tools get upgraded down the road.
My miter station is 8' long, favoring the left side as I cut from left to right. I plan on adding wing extensions to both sides, but I'm waiting until I do my next crown molding project to justify investing the time.
I made a hybrid design that was based on Ron Paulk's miter station w/ bench dog holes like the Festool MFT. I used the Kreg track system, which I highly recommend as well; it's easy to calibrate and produces reputable cuts with several different stops. I still need to add cabinets and a cubbyhole for a shop vac beneath the saw.
My original idea was to mimic Jay's dust collection design, which is why I added T-slots on both sides of the saw (see below). This way I could remove the dust schrod as needed when doing angled cuts.
However, I always try to follow the KISS method - keep it simple stupid. I think my dual 4" dust port setup will work and it's easily removable as it's a pretty simple jig. Not sure my dust collector has enough ass though
