Frank Posted March 18, 2016 Report Share Posted March 18, 2016 You could also put a little bend in the rod. This will keep it in place till it cools. The picture I posted has a rod but what it does not show is it has a little swage mark to keep his weight from sliding. But his inserts are machined to tight tolerances. If you are using lead then the bend will work fine. 1 Quote Link to comment Share on other sites More sharing options...
