Niki,
This is without a doubt the most sophisticated sled I have seen. I will say this, your photos and text make a complex build seem rather straight-forward. I have need of one of these as well as a miter sled. You have given me a lot of ideas and, to be honest, I would not know where to even think of trying to add an improvement. You simply have engineered an outstanding product.
A simple thank you somehow seems so lacking for all the time, effort and work that you have put into this series but it is heartfelt and I really appreciate the entire post.
Thank You.
