DIY arrow saw ideas needed

I’ve watched dozens of videos. I know there are many plans out there. I want input on what I want to use that I already own. I have a pneumatic die grinder with a cutoff wheel attachment. I’ve used it to cut everything before even carbon shafts years ago. Back then I did it freehand. I have a couple arrow spinners that also will square ends so if the cut is not 100% perfect I can easily square them on the next step. My plan was to fasten my die grinder to a piece of strut rod. The shape of the die grinder is perfectly round so laying it on strut rod and zip tying would hold it square to the strut. My question is how would I feed the shaft into the wheel? Would I need to design a hinge that would allow my die grinder to hinge up like a chop saw or make the arrow table slide in and out like a table saw mitre guage? I want to keep this simple and effective. Ideas?

I put a diamond cutting wheel on my dremel and attached it to a 4 ft length of angle metal with a hose clamp. If you set it in there right it sits square. I then drilled a hole in the end of a 2x2 piece of lumber and use a hose clamp to attach it to the angle metal at the length I need (nock sits inside the hole). It cuts them off very close to square and I just touch them up with the squaring tool after.

Well I have a need to cut some shafts and am too cheap to fork out for a proper saw like many of my brothers. This thread and a couple of others inspired me to come up with this drawer slide cutting contraption. Still need to add a tape and possible thread an thumb screw to lock it down instead of using a paper binder that actually works well. This was put together will all old money, stuff I already had on hand stuffed in junk boxes, wish the slide was a touch shorter but it is what is and works well.

Why do you have your drawer slide head on with your die grinder? I think this idea is awesome but if you took a couple slides and mounted them at a 90 degree angle to the grinder you could make a platform that was attached to them and slide them in and out like a table saw.

I don't know but I just finished cutting 12 carbon and 6 old 2117 eastons and it seemed to do a nice job. Would be using a slightly different cut off disk but that would have required me to visit the local hardware store. Colored the shaft end after the cut and my arrow square/spinner showed that the cuts were pretty darn square. I'm sure it could be improved upon but I was being frugal, just trying to get by with all the junk I have on hand. This is something I'll likely use two maybe three times a year if I am unlucky.

Drawer slide is actually slight offset to the dremel, only cuts a partially cut through the sidewall of the shaft, rotate the shaft like one does on a typical store bought saw cutter to finish the cut.

eta: changed things up just a little.

Like many on here I wanted to build an arrow saw but I did research and found a unit called mod saw
When I looked at all the parts I would have had to buy plus a decent spinner this made more sense even Thu I like to build my stuff
I'm the same. I had a tentative design all worked out for a saw but when I did a quick calculation it just made far more sense to buy a used one.
