There used to be dozens of books that would tell you what you needed to do.
I had an uncle that was a gunsmith and machinist and he thought the various conversions were half-assed (for whatever reason) hed always say that the conversion was a good way to F-up a perfectly good rifle. But I doubt that ever stopped anyone from doing it.
I have to agree. I once bought a used Savage 22 semi auto and the first time I tried to fire it, the weapon fired eight rounds full auto and then jammed. I took it to a good gunsmith who discoverd that someone had tried to convert it to fire fully auto. It cost me more to fix the darned thing than a new one would have cost.
