What type of tapered reamer are you guys using for your real foot calls I've been tapering mine on the lathe but would like to become more precise for a better fit. Thanks

I just concluded a personal study on how the old timers did the taper Ryan and came to the conclusion that a Windsor chair reamer is the most likely reamer used. The most common angle (taper) is 6 to 7 degrees relative to the center line of the insert.
I personally use an old reamer that I found in a tool box but the Windsor chair reamers are available from "Lee Valley" at a very reasonable price. There are 2 sizes available and you want the larger size. 7 and 9 degree reamers are also available from auto tool suppliers and are used as tie rod end bearing reamers but they run about $100 or more. A much nicer reamer but the price! There are also "Irwin" brand "handy man" reamers available on Amazon that, in the larger size, will also work and they are under $50. I also use the smaller size Irwin to smooth the inside of the insert and bell the mouth.
I use a guide I made from delrin to align the reamer with the 3/4 hole in the call barrel. I just slip the delrin guide over the reamer tip and insert the reamer/guide in the barrel and turn by hand.

I forgot to mention Ryan that it is also possible to make your own reamer.
My thanks to Marvin H for these links to "how too" articles.

This is the reamer I came up with after doing more research and the valuable information from Fred and Marvin. I added a 3/4 straight end to the reamer to keep every thing in line and its a 6 degree angle which from what I've read is about the strongest angled tennon for chair building. I've made a few practice inserts with it and it holds very well. Thanks for everyones help.(http://i1368.photobucket.com/albums/ag167/roosagamecalls/IMG_20150625_192226315_zps9xbpcdrw.jpg) (http://s1368.photobucket.com/user/roosagamecalls/media/IMG_20150625_192226315_zps9xbpcdrw.jpg.html)

FDR..again thank you for all your advice on reelfoot.
How about a photo of your delrin guide for the reamer tip?

Here are a couple pictures of my reamer with the guide in place. The guide is an approximately 1 inch long piece of 3/4 inch diameter Acetal (delrin). I turned the outside diameter to 0.740" to provide some working clearance in the 3/4 call barrel bore.
To make the guide I placed the delrin section into my collet chuck and drilled a 3/8 inch hole through the piece. I then placed the reamer in the tail stock, hand turned the lathe spindle and advanced the reamer into the 3/8 hole until I had almost penetrated the 3/4 delrin section.
As long as the guide does not bind in the call barrel the reamer will follow the hole in the call barrel without cutting into the guide. I would guess that a wooden guide would also work but I have not tried one. I got the delrin from ENCO. Look for Acetal rod. I hand ream the taper for the insert into call barrel and the drill chuck is merely a convenient way to hold the reamer.
