NOTE: PHOTOS WILL FOLLOW!
i needed different rods than what was in my carb in order to fatten up the mix some. A 9000 series emissions era parts carb had some very lean rods which were 67/57/54 when measured.
I modified them to 67/52/42.
I found out that in my cheapy drill press (one of those Chinese ones sold undated many names) that I could chuck up the TQ rods as the bend fit above the jaws.
So after some experimentation I figured out that, with the drill press running, holding a jewelers/points file wrapped in 220 would cut the brass better than most grits. (I used the bare file to make sure the sections of the rods were flat.) Then with the drill press still running I pinched the rods holding 800 grit to polish them up.
The rods need to be shaped roughly in thirds. The narrow power section all the same thickness. The middle section can taper from the fat cruise section. (See photos below)
This takes a little careful attention, measuring frequently any changes so you don’t go too far. Also, if your drill press has any vibration as mine did, just stop and rotate the rods 45* a few times in the chuck so they don’t turn out with oblong cross section.
