New Crosscut Sled.
First off using the table saw without a blade guard and riving knife (splitter) is illegal in commercial workshops in the UK. However as I work alone I can do as I please in the privacy of my own shop.
I will say though, I only use my table saw for crosscuts doing all my ripping on the bandsaw.
So with a high end table saw fitted with a rock solid sliding table why do I use a crosscut sled?
Firstly for a splinter free cut, to the both the left and right of the work as well as the rear.
Secondly it cuts dead square, the aluminium extruded fence on my Felder saw is very fiddly to set and once you tighten the knobs it flexes. The fence on my planer thicknesser suffers from the same problem.
Thirdly it supports the work both sides of the blade which actually helps with safety as the off cut can be moved completely clear of the blade before removal.
Lastly it allows me to make cuts against a stop either side of the blade
None of this is new to woodworkers in the US.

Below you can see the zero clearance either side of the blade.
Although I've used a simple sled for a few years, there were two major improvements I wanted to make. Firstly I made it bigger, 3' to the left of the blade and 2' to the right with a 16' capacity. With anything greater than 3' I could use the telescopic arm and stop on the table saw fence taking it to 6'.
Secondly I was fed up of clamping on bits of wood as stops, then measuring, adjusting the clamp and so on until it was just right. So enter 'Flipstop'.
This is an industrial piece of equipment with a price to match but I've used it for many years on my drill press and it is superb http://www.flipstop.com/. Rock solid, easy to adjust and with no play whatsoever. The fence has elongated screw holes so you can adjust it until the scale reads absolutely spot on, no more tape measure! A pair of stops is very useful as you can retain a setting by flipping the stop arm out of the way. This is great when cutting box sides with continuous grain as you can alternate from one stop to the other as you work down the board. This will get plenty of use preparing the parts for the tool chest course in the summer for New English Workshop.
Here's my drill press setup, the stops are being borrowed on the table saw and are easy to swap over as needed, at £61.20 per stop I didn't feel like buying two more unless absolutely necessary!
So that just leaves me with the 'get out' that all the magazines over use over here, 'guards removed for clarity', what a load of b******s!
