Can you tell us how you built it. What materials and where you bought them. It is very neat and is something I would like to do to my own.

Looks like something I would be interested in....I know I have kept running more than once and discover powder trailing the case.

Nice job! But my press has no primer follower. Looks like a piece of brass rod, is thst what you're using?

Thanks guys!
MrHill, I'll post up a list of materials shortly.
garySTL, my press is new and the follower rod is a fiberglass rod. I'm not familar with the previous LnL AP's but I would think it's basically the same thing.
BYJO4, I have given it some thought but it's very easy to build. I'll post some instructions very soon.

I took a Sharpie and drew a black "empty" line around the primer follower rod. Looks like you did the same! I noticed a mark on the rod when you removed it from the primer feed tube.
Your design seems like a good one. Very clean.

Thanks Crunchy, I did draw the line and it helped some. My problem is I can't see the follower when seated at the press and got tired of cleaning up powder.

Great job.
Like others I use the black line on the primer follower.

I bought my LnL a few months ago, #40660, and it came with the fiberglass follower. Interesting to note that on the instructions it is called a "fowler".
Apparently that is a relatively new addition. 1/8" brass rod will work also, just don't let it slam down onto the primers.
Very interesting creation Dave. Looking forward to more details.

Info for building the primer Buzz Box.
Sorry this diagram got turned wrong. Not sure why that happened.
Parts needed from Radio Shack:
Project Enclosure Box 270-1801
Lever Switch 275-0016
Mini Buzzer 273-074
9 Volt Battery Terminal (sorry no part #)
2, 2-56 x 3/4 machine screws
2, 2-56 machine screw nuts
Glue. I used contact cement.
Red and black 18, 20 or 22 gauge wire. I robbed mine off some old electronics.
You will also need a soldering iron and some low-temp solder.
Note the lever switch is mounted at an angle. You will have to play with this a little to get it just right. This can be tricky so just take your time. Remember the box is mounted with a short piece of two-sided tape on the bottom so allow for that height difference when locating the position of the switch. Once you have it located drill two small holes for the machine screws to pass through for mounting. It is easier to solder the wires on the switch before mounting.
Drill two small holes in the top of the box to allow for the buzzer pins to pass through. Pass your wire out through the holes and solder them on first then put a dot of glue on the bottom of the buzzer. Push the buzzer pins with wires through the small holes and allow the glue to dry.
Locate your battery inside the box. I just left it loose for replacement. This buzzer will use very little current for very short periods of time so a battery should last a long time.
Now that the box is complete clean the press base good with alcohol or contact cleaner to remove and oil. Before peeling the backing off the two-sided tape, play with the mounting location to be sure you get the right location. Mark the foot-print of the box on the press so with will know the proper location when you are ready to stick it down. This is a little tricky but not bad. If you goof it up, no problem just pop it off and try again.
Hope this helps you guys out that want to use it.

Nice. Very well done. I may have another project to try to take care of. I know I have made a mess a few times.

Cool idea on my way to the local radio shack now, thanks
Missed this back in December thanks for bringing it back up. While I can feel the difference when there is no primer to prime with I just might have to do this as an added measure. I like how its all down out of the way and won't interfere with the powder measure.
