This is how I went about adjusting the amount of powder that the LEE Auto-Disk Powder Dispensers are pre-designed to dispense.
If you're anything like me, the amount of powder that I come up with in my more accurate load workups rarely ever falls neatly in line with the pre-made holes in the Lee Auto-Disk System.
I'm sure alot of thought went into coming up with these predetermined powder volumes that they put in their disks but dang it, I've never found them optimum for the rounds I've reloaded.
That's not to say that they don't work well, even at those pre-set volumes. They work fine, just not as fine as they could work once a person works up a better load.
I'm sure this topic has been covered before by the do-it-yourselfers in this group. I was just to lazy to go in search of any other posts made on the modified Lee Auto-Disk Powder measure/dispensers.
I did come across a few DIY mods to adjust the volume of a given existing Auto-Disk-Hole. For the most part, they entailed drilling and taping a hole in the wall of the hole and just screwing a set-screw through the wall of the hole and into the main chamber/hole.
This was enough to alter or adjust how much powder was in the powder hole of the disk. By all accounts, this seemed to work out well enough.
I was just reluctant to drill holes in my newly purchased Lee Auto-Disk components so, I came up with this 3D printed version of the Adjustable-Powder-Volume Auto-Disk.
I'm also sure that there are easier less complicated ways to get around this. This is just
the way I went about it.
This photo is a CAD Rendering. Although my 3D print looks just like it, the color of my print is solid white. I chose these colors in this computer rendering simply because it allowed for the showing of more detail than a solid white colored rendering.
It took me three tries to actually get all the measurements right. Even then, my 3D printer doesn't have the resolution to print out models as pristine looking as this CAD rendering.
I have to print them out about a thousands or two larger or smaller depending on the part or area of the part, and then manually sand or file them down to as close to a perfect tolerance as possible.
I pretty much got it down to where the manual sanding or filing is minimal but still, there is some post-print work involved.
In the end, I made myself something that the LEE Auto-Disk System should probably think about offering without it being an expensive optional feature.
