BoschFSNWAN Track Miter Guide

Makes angle cuts much easier and faster for multiple cuts

The ability to accurately make cross cuts with my track saw typically requires meticulous measurements and a square of some type. Using this miter guide allows me to make accurate square 90 degree cuts on sheet goods and small boards. The ability to make other angle cuts accurately is an added bonus. This is a fairly expensive accessory but well worth the investment providing another lever of use for my track saw.

I'm surprised how many people use this FSN WAN as a rail square. Benchdogs makes one if you're using your track saw mostly for breaking down sheet goods. I've used this to cut stair stringers, scabbing in sheathing on siding jobs, interior plaster cutback, and gable cuts for Hardie siding. In short, it's an excellent tool just be aware that just this tool + a Bosch track saw isn't enough. You'll want longer tracks, a track connector, and track clamps. Stair stringers are tricky if you're using 2x12s, since the flatness of the boards matters. If you're using this FSN WAN miter gauge with LVL, you'll fly through stringers and get stairs that line up perfectly.With Hardie boards, you'll get near perfect cuts but a vacuum is a must. Otherwise the dust will clog everything up. Using this FSN WAN to cut gable angles for your Hardie panels is about a perfect application for this tool. You'll get smoother cuts, and fewer warranty issues. My $1600 siding table didn't survive a year of making Hardie dust, Bosch's product does just fine with it. Make sure you get a PCD blade with a 20mm arbor if you want to cut fiber cement products properly (watch out, they're expensive but worth it).Overall, I think for about $1000 you can have a very effective track saw setup for carpentry and siding. Better, in my opinion than Makita or Festool.

The FSNWAN attachment allows you to make miter cuts with your Maffel rail-compatible track saw. I use it while building in the attic as it is more convenient than running outside to the big miter saw. You can also extent the miter guide with any of the Bosch FSN or Mafell rails to cut angels in sheet-goods. As the other Spanish reviewer noticed, you need a connector which is not included if you extent the miter guide with another rail piece. Track-saws and their accessories are expensive. but once you own one, you do not want to miss it. The tracks can also be used with other compatible tools such as jig saws and routers. As a background, there are essentially two standards for rails, and both are from Germany: the Mafell one (Bosch licenses and is 100% compatible) and Festools. All other rails systems are knock-offs of either one of these two rail systems, mostly then one from Festool and are compatible to varying degree to these.

I love this Bosch square. Does the job what I need it for.

Algo que es extremadamente molesto, es que compres una accesorio como este que podríaaaaa ayudarte en gran manera y no lo puedes usar porque requiere otro accesorio mas que es el conector negro "FSN VEL"para unir la guia con esta escuadra, el cual su costo es de $1,400 pesos!!!! Por una pieza pequeña que DEBERIA INCLUIRLA. Asi que si vas a comprarla compra el conector "FSN VEL"

First thing first, this is not going to replace a sliding table saw but can replace your regular table saw.There’s a 90 degree notch on its body but I wouldn’t trust that.

Scale is somewhat imprecise. Even the notch won't give you precise 90. It's just so slightly off you never notice with naked eye. I have to lock it against a known good carpenter's square for precise 90. Once locked, the setting remains in place securely and does not drift. Works very well for breaking down sheet goods to rough size. I would probably not trim panels to final size/angle with this unless I have nothing better available to me (panel trimming jig for table saw, slider table saw etc.). For the record I would not use a track saw anywhere I could safely use a table saw. If you plan to use this on the floor, get at least 1" thick foam board under your sheet - this jig requires a bit of space below the sheet for the cross bar and a locking nut and won't work with 1/2 foam sheet in most cases.

Really is a sturdy piece of tool. Makes precision angles and cuts repetitively. Worth every penny.
