The 3D printed Micro adjustment upgrades your existing powder bar to a micro adjustment powder bar.

No more guessing how many turns of the adjustment screw will get you back to that perfect powder weight.
Much more than just a dial or knob.
There are 999 adjustments possible.
Every turn is 99 adjustments and then every compleet turn is 1 number comming up on top.
Tip for easy turning, just put on 3 places a very little grease on the screw thread and on top.

NOTE: the dail knob don’t say how many grain of powder you have (it’s not posible becourse every powder has its own volume/wight), so it just learn you to find back a known position on how many grain’s it wil give on that number.

Start to turn the bar complete in to the lowest volume what is possible.
Put the frame (large ore small powder bar) on the bar and secure them on the bottom with the Allen wrench. Warning: can be tight fitting.
Put the dial knob on zero/zero and place in the middle of the frame and secure it from the side with the Allen wrench. Not to tight, knob must can turn.
instal paper included.
NOTE: do not overtight the 2 little screws, they are just there to keep it on place. It’s just turning in 3D printed plastick but they are just there to keep it in place and are strong enough.

You will be able to return instantly to any powder weight setting with a speed and an accuracy never before possible.
Of course, you still must weigh and confirm all powder weight setting changes.
Depends on what kind of powder is used and make a schedule.
