Hellow Happy,
You may not be real happy reading this but,
I saw the same Woodsmith post about having a tools attached to the saw fence, I personally would not do it for a few reasons:
1. It adds clutter to the work area and the gear can be located elsewhere, for example a magnetic attached box on the cabinet side.
2. There ia a risk that all the extra load will make the adjustment of the fence inaccurate as its dragging a heap of monkeys with it.
3. the addition of the clutter (Tools) it adds the risk of an accident happening by means of a Foriegn Object if something was to dislodge. Check out your steel rule for one.
4. It also provides the opportunity to just grab something whilst the blade is exposed but not necessarly working and, by sheer accident it might add drop it onto the blade damaging it or if its rotating returning the item quicker than you can duck, even a plastic or soft item hurts at high velocity, just ask any paintballer!!
As for the fence mod by Bob Van ********************, I have something similar but without clamps, it attached into the fence edge grooves.
Maybe I will post a picture of the fence, but my saw is 14 years old and no longer made so few LJs would have something that vintage.
Purely my opinion and not intended to belittle your work practices in any way, just another avenue of thought to consider.
So after say that just where would the gear go?
Some suggestions for relocation:
Tape measures pencils and other associated tools could be located on the workbench nearby, or on your ear, (I have big ears) or as mentioned earlier in a caddy on the side of the saw just the spot for mag switch feather boards and the likes.
There is however one iten I have on the saw top and that's a 6" steel rule, which lies in the gully of the rip fence slide at the front of the saw.
Your big steel rule if you must have it so close fit some magnets on top of your fence and firmly attach it there please.
This all coming from somebody with no formal skills no workshop and no scientific evidence to support their claims but I thought it worth mentioning anyway.
Good job on your fence BVD fence
