That gives 1400 - 210 - 170 = 1020mm of cutting width.

Your measurement is too conservative here but it is a good start for "comfortable work".

The saw slides on the cams, not on the metal groove, so you actually do not need the full base to be on the rail, just the cams must be on the rail. This allows to subtract about 50 mm on either end.

So the 1000-ish mm cut capacity is correct for "comfortable" cut without too much fiddling. But the true "max accurate cut" capacity is somewhere around 1150 mm for the TS75 on a 1400 rail.

Either case, it is too little for a full cross-cut but not by as much as would be indicated.

I have a marked lines on all my tracks where my track should meet the material and where the end of the saw should go for max cut capacity. I use these lines to place the rail, connect the GRS and where place the saw bedfore starting it. All without having to fiddle where I am.

For a TS 55 saw I have the "material start" line 300 mm from the rail start and I always place the rail so it is just whole on the rail. For a TS 75 I would use same approach but with a mark about 350 mm from rail start.

I also have a mark at the rail end, about 100 mm from the end to indicate where the rail is *supposed* to overhang the material. Ideally.

Works really well, sparing me the need to think/check where I place the rail or the saw.

I totally forgot yesterday, but I did get it together today.
From the back of the base plate to the point where the blade meets the base plate in the front.
Setting the saw for a 6mm depth of cut:
TS 55 - 8 1/4" or 210mm
TS 75 - 10 1/8" or 257mm

Setting the saw to full depth:
TS 55 - 9 5/8 or 244mm
TS 75 - 12 3/4 or 324mm

All measurements are of course approximate, no need to be crazy about it.
