Today I tried my first sac replacement. It was easier than I thought except for trying to make a straight cut on the initial sac. I used a #16 (for an Esterbrook J). I measured and then cut the end of the sac. But I needed to make a second cut to achieve the recommended straight-across cut. (Must get some better scissors!) I then went on to install the sac. Now that it's done, I am concerned because it looks a bit short. I used the advice for lever-fill pens to ensure that the new sac does not extend past the end of the lever when everything is reassembled. And mine meets that criteria, but it looks rather short nonetheless. If this simply means that it won't hold a lot of ink, that would be completely okay. But if this means that the lever and J-bar mechanism will not properly engage the sac, that of course is bad. I will have to wait for everything to dry before dusting the sac, putting the pen back together again, and then testing it. But in the meantime I thought I would post this question... Is it possible that I've made this new sac too short? (And what is "too short" for an Estie?)
Thanks for all the terrific tips and tutorials in these threads. I would never have considered trying this a few months ago!
