Uniflow Mounting Thread

[Ritchie]

Does anyone know the mounting thread on the RCBS Uniflow powder measure? It appears that the mounting plate with threaded hole is not available separately.

I believe it's 7/8-14, same as a normal reloading die.

Edit: it's 7/8-14, my uniflow3 threads into my rock chucker perfectly.

7/8-14 same as dies but if you’re making a stand it’s about as easy to buy a 1-1/4-12 nut and a Lee or Hornady quick change bushing.Then you can turn the measure 1/4 turn or whatever and dump it.Lot quicker than running the powder thru the measure

I have several Uniflo measures as well as a couple or more Lyman and maybe even a couple others from back in the late 50s - 60s. They all use the 7/8-14 threads. Well the Lymans have an adapter sleeve but same thread.

As mentioned by Willie, if your building a stand go with the nut and quick change bushings. I've got a couple of stands I built, but it was before the bushings were available. If I used them on a regular basis I would probably do the change.

Here’s what I’ve done with a Lee stand and a couple of spare nuts.

I do like wild willy’s suggestion to use a quick change bushing if you’re going to mount Uniflow in a “non-dumpable” configuration.

You will thank me later
All the plate does is hang it over the bench, how useless.

+1 a 7/8 hole is easier than a hole with 7/8-14 threads and the knurled nut he’s got on the bottom could be spun off quickly to empty if you had it mounted solid.

While I too have that very stand and it is handy as heck, I always thought that the mounting bar was for mounting the measure to the press like this.......

It is. That's the way I did it 50 yrs ago. If tight on space it works good. Soon as I dumped the powder I seated the bullet.

I really like Hornady's L-N-L stand. A L-N-L bushing on each powder measure a it's quick and easy to change measures and empty the hoppers.

Well DUH!, So that's what it's for, I have the old dual drum and never dawned on me!

This is what I do as well. Here's my setup...



My shelf is 3/4" plywood, with a hole drilled and the LNL adapter threaded in. I put the adapter on the powder measure and snugged it down, then threaded it in, gives plenty of leverage. The wires on the measures are just to keep me from dumping a charge in case I bump the lever.

Old aluminum sander disc. No wrenches required,tough to describe but they get very tight.... yet,give one a twist and enough clearance is created that the bttm nut spins off(to dump).
