I knew the Bigsert didn't hold well as I have had to repair several heads that had Bigserts. Then I have to make a reallybigsert, but with coarse threads so they hold.Another fascinating surprise, Jim. Thanks for posting. Definitely not what most of us would have expected. I've been using the Timeserts routinely for years on cases, cylinders, and heads on the assumption that they were stronger than helical inserts. Oh well, at least I haven't had any of them fail (yet). And in some cases, there just isn't enough room for the larger diameter inserts (like with cases bored out for 920 liners). In any case, it looks like the best option is a larger OD insert, if possible, and very coarse OD threads whatever the insert size.
