So I have been working on some details of my overhead mount and shroud. The overhead mount was constructed of steel. I wanted something ridged since my ceiling is about 6’ above the table saw. I designed this mount in several peices. One piece of the mount has a flat plate that will attach directly to the ceiling. Another piece of steel slides up into the ceiling mount like a telescope. Several tightening knobs will be used to secure the telescopic section in place. At the bottom of the telescopic section, there is a horiontal square pipe that will enable me to move the blade guard laterally, open up the side section of the dust shroud and then be able to cut tenons on my saw while still having above table saw dust collection.
The guard lift is made of aluminum bar stock, a steel L-frame, and some birch hardwood. it is a parallogram configuration like many on the internet and will be counter weighted to make lifting the blade guard balanced. Here is some progress:
