After an enforced break, I'm back to working on an old table saw I bought (https://www.woodworkforums.com/f153/cleaning-table-191900)

One thing I'd like to do is to fit a proper Biesemeyer style fence and a cabinet incorporating side extensions.
What's a good size for the table extension? How much left and right of the blade?
Extensions will (probably) be 19mm ply supported front and back on angle iron as used for the fence


Neat fence design


Cabinet design.
