Re: Chamber Reamer Tight
How much are you cutting before you pull out and flush / re-apply cutting oil?
As William said, the flush sytem is the way to go but I chambered many barrels with Rapid Tap or Tap Majic before I started using the flushing system. I have had my reamer get tight before but I usually found that I took too much of a cut and let it get "dry". As you get deeper into the chamber, you will need to take less and less of a cut as you can only get so much cutting oil on the work. This gets worse on larger "magnum" type chambers.
The second possible issue is that your pilot is "too big" for the given chamber you are running. You may be getting a tight pilot....Just a guess as you did not post what type of reamer you are using. Sometimes when you use a reamer pilot that is really close tolerance, add some chips and a little temp change from the cutting process, things tighten up and will give resistance.
my 02 cents worth.....
Hope it all works out for you,
