Simple vertical blade in a frame with guides and pull the sand paper though by hand. Don't over complicate it.
try the angle grinder with a 1mm or 0.8mm discI dont think that will work - i think ill get a ragged edge, or it will start to tear, or go off line. The paper is tougher than standard paper, which is why i use it. I can buy weak paper in 103mm rolls, but its no good.
The frame and blade is my preferred idea of the moment, as im not sure a guilotine will be a whole load better than doing it by hand - i mean it will be quicker, but just as tedious.
I think the frame idea is good, but i think it will, somehow, need to be a powered blade, be it hand powered stanley in a jig, or rotating, or bandsaw. Ideally electric, so i can just, as you say, pull the whole roll through in one go.
Im wondering how long those thin ceramic dremel discs would hold up.
^^exactly this, not worth the grief. Life's too short to be working round a permanent problem all the time. If it was a one off or seldom needed, then aye, but regularly, no way. Flog it on to someone else, and buy one of the easily available size would be the way I'd go.Cough.
Buy another sander.
Cough

Are they not around 30k?A paper slitting machine will be your friend, but by the time you’ve got one of those it will be cheaper to buy sand paper from the states
What about a saw bench with very fine blade. Paper roll held in place by a wooden board.I dont think that will work - i think ill get a ragged edge, or it will start to tear, or go off line.

I dont know exact costs but they will be expensive, hence why i said it will be cheaper to buy the paper in the correct size.Are they not around 30k?
I only commented as a cheap slitting machine would be great for me.I dont know exact costs but they will be expensive, hence why i said it will be cheaper to buy the paper in the correct size.
Ive had a quick blast around the internet this morning. 103 mm paper is available but it seems to be quite expensive, so i guess the OP is looking at saving some money by cutting down 115mm wide rolls.
Got a photo Brad?Yes. You'd use a tape cutting machine like the one I've got sat in my yard
Why do you need a cheap slitting machine?I only commented as a cheap slitting machine would be great for me.
When I had this issue I ended up relocating one of the sandpaper holding clips on the drum to allow me to use full size (115mm) strips. Post a couple of picture of the drum to see if this is viable.
