Electric Screwdriver/Neck turning

I used this Ryobi for a while since the RPM's were reasonable https://www.homedepot.com/p/RYOBI-4-Volt-Lithium-Screwdriver-HP34L/302648210

I stopped using it after I realized that being able to change the RPM based on how much I was taking off, or the diameter of the neck (smaller = faster). Dug though the project bins and made myself a jig that holds the turner, allows me to move the brass in and out, and has speed control. I did have to buy the joints, but everything else including the shell holders was already on-hand.

I do not use an electric drill because I have an electric neck turning motor that we built. I suppose the proper screwdriver with the proper speed control and proper torque will do the trick. I would think you should do something to secure the driver to a bench or solid base of some type. It’s impossible to hold the driver and the neck turner and have any control of what you are doing.

What are the RPM's Francis?
 
I just started turning necks with a 21st century lathe and got a old Milwaukee 2 speed cordless screwdriver to power it.. seems to be working well...
 
Anyone turning necks using an electric screwdriver? Any suggestions what model your're using would be appreciated.
I use one with my Hornaday neck turner due to a smaller size and lighter weight is great plus the trigger has 5FB61BD0-0B79-4A8D-89F0-5BDBE20BA3E4.jpeg forward or reverse without having to move another button very handy

Awesome setup. Perhaps you could help me build a robot in my likeness that can field my wife's gripes instead of me????
 
I've had good results with this Dewalt on a Century 21 neck turning lathe:

One feature I like about this cordless screwdriver is that it is gyroscopic - the further you turn it clockwise or counterclockwise - the faster it will turn.

I use the same one with a PMA tool. Works great. A guy I shoot BR with pointed it out to me, and when I saw how well it worked I bought one the next day. It charges up pretty fast too.

I use my Dewalt cordless that has a 1/2 inch chuck. The brass goes directly into the chuck and the base of the cordless, which is the battery, is placed on the bench. The variable speed trigger is operated by my thumb. My turner/cutter is a cheap hand held RCBS type which has a tool steel blade which is periodically sharpened and maintained square with a diamond knife hone. Measurements of turned brass show neck wall thicknesses variations less than .001. I doubt that holding brass by tension exerted on the rim is better than clamping the circumference of the brass in a chuck. Yes, it wobbles some but the blade of the cutter is held against the surface of the brass neck. I find that usually .001 - .003 cleans up necks and if I need to remove more I do it in stages.

I use the same set up with a Ryobi 1/2 inch cordless. I can usually clear up any wobble by reorienting the case in the chuck. I spent way too much money on Sinclair tools that hold the case head. I haven't used them since I got the 1/2 inch drill.
 
And if it’ll fit your budget, the little mini lathe has been a very useful investment for my reloading room.
 
What gearbox is that?

Gear box came on pictured grinder from Harbor Fright. Wet part was replaced by shaft to accept Lyman Universal trimmer shell holder. (around $20.00) Sent gear box to friend on forum who made shaft for it. Total including grinder and dinner for forum friend less than $100 Shaft turns 160 RPM has worked great.
