Hi. I have noticed quite a lot of people suggest using JB Weld to modify the Lee adjustable powder charge.
I just wanted to know what JB Weld would be best suited for the job ? I am planning to experiment filling in one of the auto disks and then drill it out smaller to see if I can get close to what i need.

At the moment I am using a home made job packing the end of the adjustable charge which throws accurate 60% of the time but then has issues of powder getting stuck. Hoping to find the product at this store in Australia: https://www.repco.com.au

Just ask for and buy JB weld at almost any car parts/ engineering outlet. I have used this method for years and it works fine.

I remember seeing someone made delrin inserts to fit in the larger disks. It may have been on Igor’s blog. They reported it worked very well. Good luck...

Why don't you just get a Lee Micro-Disk set?

Although Lee stopped making them sometime ago due to their mold breaking, I believe, similar products are available..

I have one of these, very high quality, and will dispense loads as low as 1.0 gr Bullseye which,incidentally, my Pardini HP really likes.

The disks look like they're made of polypropylene. Being a very low energy plastic, there isn't much that will actually form a good bond to it (there are a couple of specialized epoxies that will bond, but they generally require a flame pre-treatment which is not suitable for fine/detailed parts.)

If it were me, I'd countersink the hole you're going to fill (to keep the plug from falling through should it come loose), and use whatever JB you can get your hands on - the 5 minute stuff will be fine; the regular may run if not allowed to cure while flat, but will also work. Drill out to your desired opening, sand off any protrusions, and start loading.
