I just want to let you guys know that after three years of interrupted development I managed to make the automation work. I had to use a timing belt to increase the torque and a hall sensor over an...

Thank you all for your advices and insights. What I take away out of this is that I could benefit from a clean heating source like gas/propane or maybe even making my own electric smelter (solar...

Hi
Until now I considered lead smelting in a small smelter in the open. I look at melting range scrap, lead roofing and pipes mostly. I assume an active coal filter with fine dust filtering would be...

Hi Tazza,
I just realize another reason of not having heat issues: I use step motors with a high supply voltage: my small Nema 23 motor (for the lead pour) is fed by a driver fed on 36VDC, the main...

I could post pics but since I’m destroying everything to set up the timing belt pulleys, I need to tinker a bit more. The price for the encoder was ok, I paid something like 40€ and this is a small...

Addendum
I found it interesting to see the step motor is capable of accelerating almost instantly and stopping in such a sudden way that no impacting of the frame is necessary. I just need to tackle...

It has been a while so here is a small update
I started programming and exploring examples of code beginning of april 2020, by summer I was programming a few days per month on this project. By...

Thanks for the hint.

As I don’t have an M-die available, I took a Lee collet die in 308 screwed high in my single stage press and entered each case 3 times. The crimp was not gone but much less...

Hi,
I’m getting started in reloading 30-06 for my SAFN and have a large batch of German 30-06 DAG once fired brass in pretty good shape.

I wanted to include neck turning to my case preparation to...

For me it works lovely. You have to play a bit with the ramp angle and the angle at which the feeder itself is hooked. Also make sure you minimize vibrations coming from the case feeder to which the...

That’s a viable option, thanks.
If the custom shellplate is too expensive then that is wat I may do. Then again I hoped I could stick to the few presses I already have. Buying an extra press just...

Hi Tazza,
I used a left-hand torque wrench to measure the force required to cut the sprue of my largest diameter mold I currently have. I measured 14Nm max. I am aware that there are a lot of...

Small update - I purchased the step motors and am currently trying to write software for it. I settled for an arduino. C code programming is like 16 years ago but the internet came since then.

It...

Hi There

I know this is an old thread but just like the topic starter I want to load 25 acp on my Dillon 550. What I’m looking for is the following:
- either a drawing of the shellplate so I can...

A small step motor and a cam is exactly what I had in mind. Will create a less noisy circuit.

For the main step motor I found earlier a 30Nm step motor for 200USD and its driver is about 100USD. I...

Not so far, I had an urgent renovation at the house. But in the mean time I used the left handed torque wrench on one of my bigger diameter molds and found out the torque that would stall the motor...

OK, thanks for the hints, then I’ll use the standard supplied Magma sprue plates after the conversion.

I was a bit concerned that if I would use Smoke’s Powder coating for rifle (rated 2700+ fps)...

Gentlemen,

I’m in the process of converting RCBS and Lyman rifle and pistol molds to the Master Caster from Magma. With the standard Magma sprue plates I notice there is a pitch difference between...

Thanks Hatch for chiming in.

In the mean time I nearly started a small machine shop for converting all my moulds, bought an X2 type mill. I acquired a Left hand torque wrench and found a source of...

Is there really no one able to help me with a rough torque estimation of the Master Caster?

Hi Tazza,
Thanks for the hints. If I use large coils like a solenoid then I will think of a diode snubber to contain the back EMF when the current through the circuit is cut. Also separating...

Ammobot? Do you mean this?

Sorry just joking ;-)

Depending on the needed torque...

Hello Everyone

I’m at the very start of automating my Master caster. I decided I would program a Single Board Computer (Arduino or Raspberry - cost effective) to operate a step motor for replacing...
