If you chuck the reamer up in drill press or mill at low speed, it takes all of 5 minutes to do. I leave about 3/8-1/2" at the bottom of funnel at the original diameter. Use lots of oil.

Thanks for the tip on the reamer. I used an 11 degree that I have on hand and the funnel now works fine. I also drilled the remaining hole out to .199 to eliminate the remaining rough spots below the reamer cut and polished the ID with a bore brush wrapped in steel wool. I have a lathe so it was easy.
I'm going to order one of the reamers like you noted above, it will move the taper even lower into the funnel. I did find some on EBay also.
