    I was thinking about ordering this Low Primer Detector and adapting it for my Lock-N-Load AP. Has anyone ever modified one of these for the Hornady AP. Or made something similar that is also self contained with alarm? It seems to be the one aspect I just cant seem to monitor properly I usually run a few rounds through before it dawns on me why the primers seem to be going in so easy (no more primers :what:) "duh" Any input would be appreciated.

    Yeah, that's annoying when you run out and it takes a few rounds before you realize it, been there, done that. That's why I made this:
    _DSC0041.gif
    _DSC0040.gif

    It cost me about $7.00 for all the parts from Radio Shack. Basically, I used the fiberglass primer rod that came with my press, then added two wheel collars to trip the switch. The wheel collars are from my radio controlled airplane stuff, but anything would work really. Initially, I had only the micro switch wired to the buzzer so that the collars would trip the switch. It worked fine that way, but it would buzz the whole time I had the primer pickup tube in place to empty new primers into the holding tube. So, I then went back and wired in the little larger black switch on the bottom right of the unit. That acts as a master switch so I can turn off the battery power while filling up the holding tube with the pick up tube. Of course, the down side to doing that is that you have to remember to turn it back on. ;) I think my version 3.0 would have a time delay switch for the master switch. That is, it turns off the power for about 1 minute, long enough to fill the tube, and then after a minute, it defaults back to on.

    The battery holder is a double AAA cell holder. The buzzer is plenty loud. I can hear it over my radio and case feeder. I just used thin double-stick foam tape to hold it to the outermost primer tube. The tape was also bought at Radio Shack. I don't have a list or receipt anymore, but feel free to print the picture and take it to the store with you. Heck, they might even help ya assemble it there!

    One thing I like about the wheel collar thing-a-mabobs is that I can easily adjust their height on the fiberglass rod thus adjusting when it alarms. I currently have it set so that it alarms with one more primer left. That way I can take off the screw thing on my case feeder actuator and finish out the five cases on the turret. That way I don't leave any half way completed reloads, if that makes sense.

    Looks like just the ticket, simplicity elegant. No sense reinventing the wheel, thank you

    I just use a length of wooden dowel marked with red tape - you do need to remember to look at it from time to time but it's very, very inexpensive and you should be maintaining at least that level of situational awareness while reloading in any case.

    I sort by headstamp so each baggie has 100 cases ... makes keeping track of primer count pretty easy.

    I just take an empty .223 casing and throw it on top. Once it gets to the mouth of the case I know that I have 1 primer left.

    I just made a brass rod with a bend in it. When the bend touches the top of the primer tube, I have one primer left. It cost me $0.98.

    Ditto the last post, except I put a piece of blue tape around my brass rod as a marker.

    I use the Dillon primer busser. Cut the plastic push rod to leave ~ 5 primers in the tube. Recharge with ~ 105 and keep cranking. Needed to add a thin paper shim for tight fit. Standard over priced Dillon product, but works OK.

    I can't speak for the OP, but for me the tape around the rod or empty case on top of the rod or whatever just didn't work for me. I was too preoccupied looking in each case for the presence of powder to watch the primer rod. So, for me, an auditory alarm is what I needed. Again, it's just what worked for me.

    metalax,

    Yes it works great. My best friend spotted one of those on eBay for $6.00 + $3.00 shipping a few years back and bought it for me. All I did was use two o-rings; one on the primer tube housing to maintain the space offset by the clamp and a second o-ring to hold the whole assembly tight against primer tube housing. Here is a picture

    When I had my LNL I used the alarm off of one of my dillon's and it worked fine. They appear identical to the RCBS one above but blue. The wooden dowl and tape would be simple enough but I personally wouldn't use a brass rod. I have never personally had a primer, much less a full tube ignite but the brass rod would make for more of a mess in the event that it did happen.
