RCBS Matchmaster question

[Sdupontjr]

If anyone has one and can measure something for me, I'd really appreciate it. I'm working on a little something and need the ID of the smaller dispense tube.

Awesome tool. I have been using one for some time now. Love the ability to program the unit to drop exactly my desire. LIke to so much I have been considering a second to put on the shelf just as a backup. Whatta Hobby!

I'm actually building a unit to mimic it to go along with my beam scale from Scott Parker. My current setup is a single motor that will dispense the main load in a set amount of time, then several relays, diodes and a speed controller drop the rpm from 400 down to a crawl for trickling. A sensor mounted on the scale trip power at my setpoint. Every now and then I'll get an overcharge. So my new 3D printed design will have 2 motors. The main with larger tube and the trickle motor with the much smaller tube for more precise measurements. Thus the Matchmaster came to mind when I was thinking about doing it.

Here is the 1st version I built a while back. The new one is different, but you get the idea.
