    Default Parker Lucky Curve - How do you insert the pressure bar?

    How is the pressure bar inserted in this Parker Lucky Curve? Does the pointy end fit into the button? Are there some gaskets needed?

    That left end goes inside the button at the top of the pen and the right end ends up using the place between the barrel and the section as a fulcrum point. Or I hope that's how it works because that's how I did two of mine. The bar, if not an original part for that pen, needs to be the correct length otherwise it either doesn't work or it will be too hard to flex with one hand, thumb on the button.

    When you press the button, that flat part flexes in and compresses the sac.

    No gaskets needed, though you will want some shellac to seal the sac to the section, and some talc to keep the sac from binding or twisting in the barrel. Make sure the end of the section is good and smooth and clean.

    Thank you!!! Does the button just pull out? Any idea how much I should trim the sac, how far away from the button end it should be? (I've got shellac & talc at the ready.)

    Someone more experienced will certainly pop in, but for my part, I keep cutting the @*(&@(* sac until the bottom is straight, and by then if it's not the right length then I start over .
    I just eyeball it. If you look where the flat part hits, there probably is a diminishing return on too much sac past the top of where it flexes in.
    The button will remain in the pen; there probably is no need to remove it unless there's something wrong with it. It should freely move if you turn the pen upside down and right side up.

    So once I sac the pen I will just slide the pressure bar in with the sac just like in a lever-fill pen?? Will the pointy end of the pressure bar "click" into place or is that not needed? I thought I saw a picture somewhere (???) that made me think I needed to slide the pressure bar in from the hole where the button goes, meaning the button has to come out and then go back properly.

    I appreciate your help and anyone else's.

    You can put it right in the barrel. It won't click, but you'll see the button pop up once it's in the right place. Then put in the sac/section/nib assembly and try to fill with water.

    Put the section in first then pit the bar back in through the button hole and install the button.

    Your pressure bar will need to be straightened.

    How do you take out and put back the button? Just pull?

    Pull and wiggle. The button has 4 fingers with little tabs that catch on the edge.

    I usually apply a little dry heat when pulling out a button that is reluctant to come. Loosens things up and prevents that dreadful cracking sound we have all heard at least once.

    I got the pen re-sacced, button-out and button & pressure bar back-in last night. Thank you all for the help! The pen is unusually huge and writes broad and wet. Now the question is: Is the flute of this pen base a good enough fit for this pen? The pen was a flea market find and didn't come with a base. So far, so good but only time will tell.

    Good job, and it looks good next to the base. Does it fit down quite deeply and feel like a firm fit? If so then hopefully it should be OK.

    Ooops just spotted that typo sorry! How embarrassing.

    The fit feels pretty good and has been okay for about 16 hours. I've had that unusual base for eons with nothing to do with it so it would be fun if it worked.

    I got the pen in a reverse-sumgai: The person right in front of me was looking at it at this flea market and my heart sank. (There's another vintage pen involved too.) I had that awful, sinking, sad, bummed feeling and then the guy turned to me and said "You want to see these?" and I said: "Yeah!!!!!!!!!!!!!" and he left.
