If you do the jig,
let me know what it would take for you to make another one.
BTW, even recent Tucker Rocky catalogues show the BD HRC insert, but in calls to BD, they say they have had no stock for couple of years. I am sure there are folks out there with the BD insert who aren't using it and do not realize how valuable the item is ....they could sell it for what they paid for it - $150! No wearing parts except the o-rings which are cheap to replace.
