I lucked into or lucked out of acquiring a Lyman accu-measure.
It came with the 3 rotors that give you 5 holes a #9s #9L #10s ,#10L and #12
I made one rotor but decided to use the 3 it came with and make them adjustable.
Well the #9 
 have the same diameter hole.
A 10x1.25mm end tap leaves enough meat left to form a reasonable thread in the #9 and #10 rotor.
No bolt or thread could be found so I cut a thread on the lathe using my special tooth metric gear.
Woo hoo.
The deepest hole in the #10L drops 6.5 grains bullseye.
Which is enough for all I need at present.
The others throw 4.5 -5 grains max which will do for my other smaller bulleye loads
I fancy my chances next time I’m in town for a few 10x1.25 short grub screws.
After a good clean out and graphite to get the works lubed up I filled ‘er up with bullseye and ran some tests.
I tried double tapping the handle both ways and was getting 0.5 grn max difference of 10 throws then weighing 49-48.5grns over many samples
Just tapping smartly to each end of throw of the lever to make sure all the powder is out of the nozzle, I was getting 0.3 gr max difference 48-47.7 grns over many samples.
Both are accurate with the single tap more consistent over many 10 throw weighting’s.
And yes they do throw different weights.
Happy as It is working
I can go forth now and load at will and increase or decrease my load on the fly at the range to tweak my loads.
I’m looking forward to using it.
I may need a little more time getting to know it but I think it should be good as gold.
What you reckon fellas?
