SIDEWINDER MITRE SLED

I just got back from holidays and my back is keeping me from playing in the shop even so I am itching to get going and the wife also has me on lite duty in the garden .
Today is a rainy day so I thought I post some of my older projects .
This is my mitre sled I made a couple of years ago and has worked out well .
The sled consists of a base with a runner attached to fit the mitre slot and also has a metal cleat attached to the bottom of the runner the rides in the T slot and keeps the sled from tipping of the back of the saw .
The fence is a perfect 90 DEG. and bolted to the sub base which can rotate on the base and is locked in place at the desired setting .
The top of the fence is a half dovetail shape which allows the corresponding stop blocks to be fastened .
Picture 3 showes the simple alignment procedure with a very accurate drafting square touching the blade body and fence .

The stop blocks have a piece of dowel attached on one face to keep the mitre tip from contacting the flat of the stop and getting damaged .
When cutting the pieces I cut the top and bottom using one face of the fence and the sides on the other .
This sled also allows me to cut mitres on frames which have different width of sides and top and bottom by setting the subbase to the proper angle and the combined sum of the angles will give a perfect 90DEG. result because of the 90 DEG fence .
See the picture that showes a frame of unequal sizing .
