So after introducing myself to a very friendly welcome I thought I would try and ask a question. I can’t work out whether this is the correct forum, but here goes…
I have one of those fret jigs for a 24.75" scale and it strikes me that with a 0.58mm kerf on the saw the end cut, where the nut is, should be 0.29mm offset, if anyone sees what I mean.
Is that the case?
Well you're cutting the standard fret slot where the nut goes anyway, the jig usually has it as one of the notches to line up so in theory that already happens. Certainly never had a problem yet myself using a ig and fret saw.
@simecircle Yes there should be a tiny offset, at least compared to using a zero fret. I have a template from Rall, and there is markings for Saddle/Zero fret. The slot for this is a tiny bit wider and you tuck it up against the desired edge when cutting the slot.
@swepri yes, that's exactly what I am thinking - especially if you compare to a zero fret! I don't think my jig does this and I notice that difference on yours is quite pronounced? Anyway, thank you so much for the response. I asked this in a couple of places and have been told I was overthinking it and maybe I am, but I am glad to have some confirmation that my theory is along the right lines!!
@simecircle Check your jig using a fret space calculator. Maybe some templates are already compensated and others are not?
On the other hand, the difference is only half a tang width, so maybe it does not compromise the intonation that much.

Good morning, I'm a bit late to the party but yes, there should be an offset for the nut position slot. I allow for this on the templates that I make for the slotting jig available in Mark and Carol's shop and this is indicated for each scale length. The only ones which are positioned for zero frets are the two Maccaferri scales. It may only be half the thickness of the saw blade but, to my mind, if you can compensate for this then you may as well do so.
