Crosscut fence zero clearance

I suspect that most here with Hammer K3 sliders have an outrigger with the crosscut fence at the farther end of the slider. This mod is for the K3s with the shorter sliders, such as mine, which is 49"/1250mm, which have the crosscut fence at the start of the slider.

The problem I have with this crosscut fence is that it cannot be aligned with the edge of the saw blade ala a zero clearance. If a sacrificial board is attached to the front of the fence, the fence loses its ability to be set to the angle scale.

Some of you may have worked out a better method, but this is what I did ...

The inside of the crosscut fence, with the shortened end of the extruded aluminium ..

A chunk of UHMW ...

… is bolted through ...

... and inserts into a tapped threaded hole ...

... creating this zero clearance section ...

The steel hex bolt is recessed out of harm's way.

As a reminder, these ends are not intended to prevent spelching (breakout), but rather to aid in lining up the ends of a board.

Once set up, the ends are trimmed lower to clear the dust guard ...

The purpose of reducing the height was to enable the blade to be lowered and also to clear the side of the blade guard.

The F&F jig was treated similarly, receiving a zero clearance edge ...

Another zero clearance end was also made for the crosscut fence when sawing at 45 degrees ...

Again, the bolt looks close to the blade, but it is not in danger of being struck.
