Re: Consensus on recutting remington 700 threads
<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: 300sniper</div><div class="ubbcode-body">keith, how are your instructors suggesting you true the receiver lug abutments? are they having you set up the receiver true to the raceway center line? if so, while it is set up true in the lathe, you should thread a mandrel into the receiver and check the run out at a couple places on it. that is the direction your chamber is going to be pointing in relation to the bolt face. if there is no run out, then i don't see any benefit to chasing the threads. i bet there is going to be significant run out though. </div></div>
Using a mandrel. It chases the threads and cuts the abutments at the sane time, off the raceway. Takes minutes. Then face off with facing mandrels that goes off the abutments, then true bolt seperately.
That takes an hour or two
