Hey Gang,
I got a ton of cases that I am working on, that little black thing is a 12 gauge round for scale.
This little tool is causing me all kinds of trouble, it needs to get put into the mouth of the case and turned a couple of rotations to chamfer the mouth of the case. It also needs to get turned over and rotated for a couple of turns to deburr the mouth of the case and it doesn't hurt to chamfer the primer pocket a little too.
As you can imagine that is a lot of turning by hand. It is a slow process and can become quite painful after a few hours.
They make quite a few proprietary tools that all run around 100-150$ but all they do is spin other tools for you like primer pocket cleaner, neck brushes, chamfer and deburr tools. I spin tools all day this should be easy to fake right?
Sinclair International to the rescue.
This 15$ tool lets you chuck a standard chamfer and deburr tool into a drill.
Now I don't have to spin it myself anymore.
The funny thing is that drills spin way to fast for this kind of job and I don't want to have to hold onto the drill. I get enough of that at work.
I built a mount for the drill and plugged it into my 3$ Dremel brand Solid State Motor Speed Controller that I picked up at the thrift store. For those of you keeping track that is a Black and Decker Pro 3/8" variable speed drill. All that matters to you is that it's variable speed. That means that the motor can stand being slowed down by reducing the voltage without burning up. Another plus to this drill is that it originally had a T handle. That means right behind the chuck is round.
It fits in to a hole in the vertical board and is pulled tight by the wire. The wire attaches on one side by a loop that is stuck in a hole with a screw though it.
On the otherside I've taken a long 1/4" 20 bolt and made an eye in the end so I could really tension the hell out of it. The spacer block under the hind end of the drill is just that. All it does is holds the end up there is no meaningful connection to the drill.
And it clamps to my bench top! Pretty slick right? Notice the pile of brass on the coffee lid in the background.
But wait, theres more!
The chuck on the drill opens up to 3/8" so a primer pocket cleaning tool fits perfectly.
So does a neck brush.
Lessions learned,
If I had a 1/2" drill that wasn't in my work kit I couldn't have skipped the tool from Sinclair.
Even my slowest drill wasn't slow enough.
The first one I built I used my cheapest drill and it was loud!
Any wobble with the tool deburring tool makes the job exciting!
Deburring needs the slowest speed while chamfering can go faster and primer pocket cleaning.. forget about it that sucker will go 2500rpm.
