Why don't we take the beat on Ed business to another thread, elsewhere, and address doubletrouble's problem in the normal, gentlemanly way things get handled here. I know I've picked on Ed in the past (I
still have that quart can of miner's lamp carbide if you want it.
) but doubletrouble came here with a legitimate problem asking for application of the collective knowledge of the site. So let's go there.
FWIW, if you go back on some of the late Ballistix999's threads about learning to do CCH, you'll note he was quite worried about things like warping the frame during the process. And everyone here just fawned on Tony and his concern. And rightly so. Ed raises the possibility of the same issue and you guys back up the manure spreader.
I don't know a hell of a lot about Parkers or CCH, but it does stand to reason that any of the possibilities already raised here - frame warp during re-CCH, crud, sear wear, worn insides generally, botched re-assembly - or a couple more I can think of (It's a no-safety gun - are they more prone to doubling? What effect re-stocking? What effect from the old rebarrelling?) might well obtain.
