I'll take a look at it though and see what I can do. The other thing I will need are the dimensions for the mating Dillon component. I unfortunately don't have one, but my brother does. Awesome! Knurled cap is 17.7mm wide x 27mm high. Basically what I'm imagining is a cylinder with a tension/lock ring at the bottom to grab on the knurled cap, with a ramp on the top for the primers to slide from the tray and dump directly into primer magazine tube. It might be easier to just make an adapter for the Lee tray, like this thing. That way you can have multiple trays flipped and ready to dump in. The top of the knurled cap is concave and 2.1mm deep, so would a convex bottom surface be necessary for the primers to cleanly transition from the slide to the magazine tube? And then a hole in the top center for the primer follower rod to slide through. The mouth/slide of that Lee tray is 11.75 wide x 5.6mm tall x 12mm long. Does that make sense? I can do non digital MS paint. |

I got the inspiration from here. https://www.amazon.com/Prairie-Dog-6-101-Perfect-Powder/dp/B00HYYNWFA I think the top piece holds more of the weight of the powder than the bottom. So, it keeps the weight between the top and bottom of the powder measure more consistent. |

Originally Posted By KPtexan: OK, I just redrew that part since it wasn't too complex. I put some slots hopefully for a slip fit, but I could integrate some sort of screw clamp for a more secure fit.

My guesses were correct, the tray needs to be angled up (pic below), and a few primers went sideways dropping from the printed part down to the top of the knurled cap. I'm excited, this thing is already 80% ready to use. Nice. If some kind of screw clamp is possible, that would be perfect, but with this rev I could just use a hose clamp. Would it be possible to add a thin walled, centered 2mm tall cylinder on the bottom surface to interface with the concave top of the knurled cap? (pic below) Without testing it yet, the only other thing that I think would make it work better is a small wedge where the Lee tray attaches, to angle it up a slight bit so tapping or vibration will make the primers slide down into the tube. Thanks! ![]()

Originally Posted By KPtexan: Glad to hear it is at least semi-functional - it doesn't always go that well on the first try! I'll try to implement some enhancements - angle the tray mount up a bit, enhance the transition from the printed part to knurled cap, add a clamp, etc. One thing that will be helpful is some more info on the knurled cap - is the concave part a cone shape with approx. 45 degree slope? What is the diameter at the outer edges of the cone? What is the diameter of the hole in the center of the knurled cap? With that info I can make it mate up perfectly with the knurled cap, and it should be self centering so it has a smooth transition. Let's see, diameter 1 = 10mm, diameter 2 = 6mm, and the slope is 45*-ish. The cone is about 2.1mm deep. |

I think instead of a cone, we need more of a tube. A tube that goes down to the top of the primer magazine tube, through the bottom 6mm hole of the knurled cap. See below for cap screwed onto magazine, with inner magazine tube visible under the hole. This thing is the filler tube cap that would normally be used to dump primers into the magazine. Actual picture of the tip on a filler tube. Also, the ID of the main body of the adapter needs to be bumped out to 18mm. I had to use a clamp to force the knurled cap all the way into the adapter, and then had to break it to get it off.

Originally Posted By KPtexan: Ok, no problem. I can make all those changes easily. I'll just slice the cone off and then add a drop tube of the proper length there. Just to be clear, that tube OD needs to be able to go through the 6mm hole in the cap and sit on top of the inner magazine tube right? Correct, the OD of the drop tube needs to be less than 6.3mm (which is the actual ID of the smaller bottom hole) and the ID of the drop tube needs to be 4.9-5.2mm. From where the primer first drops in to the top of the magazine tube, needs to be one flat smooth surface. Also, can you add a tenth of a mm to the surface of the top hole opposite the feed ramp? The primers are going over the edge and turning sideways, we want the leading edge of the primer to just touch the wall and then drop straight down as soon as they clear the feed ramp edge. |

I think I'm going to print it out real quick and check it. I've got some filament to burn and a some SPP that I deprimed the other day, so I'll check out the feeding behavior. Only thing I can't check is how it fits the Dillon cap. |

I've also updated my bullet tray to fit the presses that have the roller handles installed like those from Inline Fabrication. I moved the dovetail on the tray more to the right and there's no slope to the side of the tray on the right side. So, this should provide enough clearance for the roller handles.

I'm thinking about expanding my options for my bullet tray to other presses. I'm hoping to get dimensions off my Dad's RCBS Rockchucker press in the next couple of weeks and make something that would work for it. I'd really like to get dimensions of the LEE single stage press or their progressive press. |

That's what all my testing has been on. I got measurements for one of the newer presses from a member here. But Hornady has done another change to the casting at some point and that's really the one I need dimensions for. Most recent manufacture ones. My clamps are close to being right for that one, but if I'm going to keep making them I need to get the fit right. |

I wish I could get good measurements on the newer Hornady LNL presses of recent manufacture. I tried going to local gun shops to get measurements, but they don't even have display models anymore. They're selling everything/anything reloading as soon as it's in stock. After doing some brain storming I'm thinking the rear section may be better on single stage presses. I could come up with something that fits on the outer ribbed portion, but I could make it adjustable to fit several presses. Similar to what this guy did, but I could design it to work with my bullet trays. https://www.thingiverse.com/thing:2749171 On progressive presses the handles are more to the right, but on single stages they come pretty close to the front bar. This complicates things along with variations between brands, etc. Edit: Now after thinking over your measurements I might could make something work on that press at the front bar location. |
