I need to shave my nuts

So I need to file down the string grooves on a Tiesco nut that I've "modified" by building up the worn down grooves with glue and baking soda.

A set of nut files is around $100-$125 and I'm no luthier my any means.
I don't want to pay somebody $20 to file it when I bought the guitar for $20. I can't borrow a set because the process will be time consuming and can't be done "on the spot" if I borrow some.

Does anyone have any tips or tricks for nut filing? I've tried a pumpkin carver, but that creates V grooves and won't be good for ease of string sliding I don't think.
TIA

I've made do with a set of normal needle files, razor blades and using strings themselves to carve the slots. not quick but with diligence and going slowly you can get there. A folded bit of fine grade sandpaper to smooth it off.

I got some lolly sticks and epoxied lengths of the roundwound strings to them to get better and flatter pressure and used them like files. It's not quick but works.

If I was going to one-off it to cut nut slots, I would maybe try to wrap some 400 grit sand paper around feeler gauges and cut slots with them. You could get whatever width you want by combination of gauges and width of paper. of course you would have some trial and error. and 400 grit is only a guess. and I probably don't know what I am talking about. but take all that into consideration and it just might work.

Thanks Dave and Cur- I think I might order that kit and see how it works.

Torch tip cleaners work pretty well. A set is usually just a few bucks at the hardware store. My impatience got the best of me when I chipped the nut on my tele. I shaped a blank nut with sandpaper and slotted it wit torch tip cleaners. That nut is still on that tele, and it plays great with no issues. That kit would make it easier though.

Diamond needle files and some patience.

That file set from Rondo is super cheap... let us know if they are any good.

The classic answer is a set of welding torch tip / carburetor jet cleaners - abrasive, various sizes, a set is usually under $5. I've used them successfully to make a very good nut.
