Got the Jessem feather boards today and are they great. I have some mag type I use on the table saw and band saw but they don't work with the router table.
I also have some Bench Dogs which are really good and that is what I have been using on the router table. They set up ok they are a little pain to set up. You have to place them where you want them and set the pressure at the same time.
The Jessems are a little different, you place them were you want them and lock them down, then you set the pressure you want and lock that down. If you want to move them form side to side a little just do it and you will still have the pressure set just like it was.
Changing them from one setup to the next is kind of a mess, all the hardware you have to mess with but its really not that bad and you will not be doing it all the time.
Yes they are a little high in price but I think they are well worth it. I got 2 twin packs, which give you 2 double height or 4 single height feather boards.
What you get in a Twin Pack, 2 feather boards and a sack of hardware. The hardware lets you set it up as 2 single or one double. You also get the bolts to use with the Jessem T slot on the fence. (picture 1)
When you take a twin pack apart you have all of this. (picture 2)
In use they are great, it is so nice to set them were you want and them set the pressure you need. They are so work just fine on the saw.
