RE: Modding a 30-30 to Ackley Improved? Wanting advice.
The ONLY way to do it correctly without a lathe is to use a T handle,go SLOWLY without force,letting pilot guide you,and go maybe 1/4-1/2 turn at a time before you turn backwards and pull out to remove shavings,adding PLENTY of oil.
Using T handle you'll feel everything,drill you can't feel.
