I put the reamer in the mail to you just a bit ago. You should have it on Monday.
The helical flutes look a bit formidable at first glance but this reamer will not tend to 'dig in' or 'drive' itself into the receiver. About the only way it can get stuck is if you generate a lot of heat and then leave the reamer in the hole while things cool off. You shouldn't be doing that, anyway. There won't be enough heat to cause problems doing it by hand.
I mentioned on the phone that you'll need to verify that the small diameter of the receiver is at least .500" since that's the size of the small end of the reamer. If a 1/2" drill won't pass through, you'll need to very carefully open it up. If you do this... put some sort of stop on the drill so you'll only enter the depth of the receiver.
It has a 1/2" square shank. If you can get your hands on a large tap handle, that's the best way to get 'straight in' pressure. I've been known to turn it with a Crescent wrench but be aware of keeping the reamer straight. Remember that those flutes are actually to the left but the reamer cuts by turning it clockwise. Light oil will help it to cut but it still takes quite a bit of pressure to work at hand pressure. As someone mentioned... if the receiver is removable... the best way is to just take it off to do the work.
This should be an easy task. However... in the very worst case... you could always back off and just put an new receiver on the horn. Provided you don't completely twist the leadpipe in half!
I'm glad you called me on the phone yesterday. Sounds like you can handle this OK. I'm always reluctant to hand out information like this to 'first timers' but it sounded to me like you will know where to 'draw the line' if you have too.
