With two of these sets in different lengths, I made a pretty nice router sled for under $100. These work great with no flex that’s worth noting…

envio rapido el unico inconveniente es que los rieles estan un poco torcidos debido a un mal ajuste de los tornillos que se encuentran en la parte de abajo de los rieles pero en mi caso no necesito tanta precision por lo que me sirven sin embargo en el control de calidad del fabricante deberian ser mas detallistas ya que de esto depende su desempeño

I would have given it 5 stars but one of the rails is bent slightly so I had to straighten it, other than that great product.

I ordered this hoping to be able to use it for a new product. What I found out that it has sloop from side to side. It could never be used for anything that requires registration from side to side. The plate on top would have to be aligned to something by bars that went to a slot or groove on both sides to make sure that it was registered for a right angle. From what I can see it does rotate about the z axis from side to side (if you are looking down the track as a front view) by about 5 to 10 degrees at least.It does side easy enough but not good for accuracy. If they had made something that registered it to the track so that the plate is parallel to the track then I would use something like this. It would have been very easy to do, but they did not. I can recommend this for anything that needs registration.
