Seems I saw a recent post where some fellow had been advised to file a draft/bevel on the parts to be let in.
He cut about a 45* bevel. That's about 40* too much. So now when I see folks give this sage advice I worry that the recipient might not "gather" exactly how much. The exact amound is never critical, but it doesn't take much-and too much can create problems.
If you're giving up and simply don't care to do it, you should probably post in the trading section. Here in the building section we're just going to keep nudging and advising how we think it might be best for you to proceed.
PICS of this one or of previous work might help let us know at a glance what your current skill level is, as well as exactly what someone might be dealing with if they took on your work. Or they might help us best advise you just how to proceed.
Pre-carves are hard (according to everyone I know who builds rifles) and can be more so when the inlets are started. I'm all for letting someone else put in swamped barrels and drilling rr holes, but I did a couple before I'd let myself farm that out. Best of luck and progress.
