The Star Primer Feed Mechanism

The next steps in bringing the Star progressive reloader back to life focused on the primer feed mechanism. That subsystem consists of the primer follower rod (the upper red arrow in the photo below), the primer magazine (the middle arrow in the photo below), the primer pickup and feed mechanism (the lower red arrow in the photo below), and the primer seating device (which is under the base of the reloader, as you’ll see further along in this blog).

In looking at the primer feed mechanism, the primer magazine , and the primer follower rod, I could see they were mighty funky and thoroughly oxidized. I wondered if they were all made of brass. The tip of the primer follower rod obviously was (see the photo below), and probably the feed mechanism base was, but the magazine tube and other parts were so corroded I couldn’t tell.

Then I realized I had another question. See the spring in the photo below? That one through me for a loop. I couldn’t see that it served any function, and all the online references I found for Star reloaders did not show it. So I sent an email to my good buddy Bruce over at Star Machine Works (the outfit that restores and sells parts for Star equipment).

Bruce responded quickly. Here’s what he told me:

Hi Joe,

The spring is a hitch hiker on your machine. Nothing to do with a Star.

Bruce

A hitch hiker. That got a laugh.

The primer pickup and feed mechanism (shown below) is what takes primers from the primer magazine and pushes them below the empty case. That L-shaped lever on the right? It’s the primer slide angle lever (shown by the lower arrow). It’s actuated when the primer feed cam (shown by the middle arrow) descends as the tool head is lowered on each stroke. The lever in turn actuates the primer slide in the feed mechanism (shown by the lower arrow), and that’s what picks up a primer from the magazine and positions it underneath the empty case.

With the primer now in position beneath a .38 Special case, it needs a way to be inserted into the case. The Star has a clever way of doing this that takes advantage of the fact that there’s a shaft in the tool head that descends with the tool head when the main lever is pulled. When the main lever is actuated and the tool head descends, the shaft fits through a hole in the shell plate and extends into the base of the reloader. The tip of the shaft pushes one end of a pivoted lever down, and that then pushes the other end of the lever up. That end actuates a plunger that seats the primer into the empty case. Here’s what the lever looks like underneath the reloader.

Like I said, it’s all quite clever. The guy that designed the Star was a mechanical genius.

Here’s a photo of the primer follower rod. It sits on top of a stack of primers in the primer magazine. Its weight pushes the primers down each time one is transferred from the primer magazine by the primer slide.

The knurled knob below allows you to grasp the primer magazine to remove the tube from the primer feed mechanism. It doesn’t unscrew; it’s just a tight slip fit into the feed mechanism.

When I removed the primer magazine, I could see that the tube was made of brass. There were still a couple of primers in it. I doubt they would fire; they were probably soaked in oil.

When I removed the primer slide angle lever screw, the primer slide was pushed out by its spring. As I was disassembling the primer feed mechanism, I found that the primer slide still held a primer. These parts were pretty funky. In a working reloader, you don’t want any oil in this area. It will contaminate the primers and make them inert (we only want “ert” primers when reloading ammo).

Check out the funk on the primer slide angle lever. This machine had been rode hard and put away wet, I think. My spraying it down with WD 40 to clean didn’t help in that regard. But it sure helped to clean up the Star.

I then unscrewed the two screws holding the primer magazine socket to the primer feed mechanism housing. Here are the parts in all their glorious funkiness.

The primer feed mechanism base is attached to the steel floor base with two large Allen bolts.

I removed the Allen bolts and then took the primer feed mechanism base off the machine. It had two pins to locate it on the Star reloader’s base.

Here’s another exploded view photo of the primer feed mechanism and its components.

The photo below shows the reloader’s steel base and where the primer feed mechanism attaches. The upper two arrows point to the Allen bolt attach points. The lower two arrows point to the locating holes (this is where the two pins mentioned above fit). The arrow in the middle points to the hole for the primer slide spring. The rectangular slot is where the primer slide enters the reloader base to position a new primer beneath a .38 Special case.

The steel base is a blued steel part. It’s just like the bluing on a gun. This is a pretty cool feature. There’s a fair amount of corrosion and discoloration on my Star, but it’s part of the machine’s charm. I hit it with some OOOO steel wool and Kroil, but I’m not going to reblue it. I like its patina.

I next turned my attention to the primer magazine (the long tube I pointed out earlier). When I withdrew the primer magazine from its slot, I could see the lower end of the tube was brass, but I still wasn’t sure about the entire tube. I went to work on the tube with Scotchbrite and that did the trick. Hello, Beautiful!

I worked on all of the primer feed mechanism’s brass pieces with Scotchbrite. The brass finish came up nicely. This project is coming together fabulously well.

After cleaning and polishing everything, I reassembled it all. I could have polished everything to a mirror finish, but you know the drill: This is a resurrection, not a restoration. Like I said above, I like the patina look. This machine might be older than me, and I sure don’t look like new. We match, the Star and I do. Old. Funky. The ultimate in personalized patina. That’s us.

In the photo below, you can see the primer cam to the right of the brass magazine tube. It’s the part that actuates the primer angle lever. You’ll get to see it all in a short video in just a minute. People like videos, Gresh tells me. We aim to please.

It’s beautiful, isn’t it?

So how does it all work? Gloriously well, thank you. Take a look:

Next up? It’s going to be the case feed mechanism, and that will be the topic for our next Star blog.

I’ll share with you that the blogging part of this Star resurrection business is lagging behind the actual resurrection. Yep, I actually have the Star running already, and it’s running well. You’ll see how I got there in future blogs, and those blogs will be right here in the not too distant future. But I don’t mind jumping ahead a tiny bit to tell you that I picked up my Model 60 Smith and Wesson yesterday morning and I fired the first few rounds I made on the Star through it. They worked just like they were supposed to, as did the Model 60. That’s a story for a future blog.

Stay tuned, my friends!

Hey, here are the Star resurrection blogs so far, along with our other Resurrection projects!

The Star Powder Dispenser

I’m going at the Star resurrection slowly, methodically, and piecemeal. I suppose I could completely disassemble the thing, clean, degrease, and polish all the bits and pieces, and then reassemble it all. But I’m a little bit scared I might not remember how it all goes back together, and I don’t want to spread everything out and make my workbench unusable during this resurrection. Nope, slow and easy is the path forward for me. I’m doing it one bite at a time and I am enjoying the meal.

The Star Powder Dispenser

The first bite is the powder dispenser. It’s the deal that automatically dispenses the right amount of propellant each time the Star’s lever is pulled. It consists of a powder hopper subassembly (the upper arrow) and the dispensing mechanism (the lower arrow), as you see in the photo below.

Here’s another photo of the dispensing mechanism. It mounts to the Star’s upper plate (Star calls this upper plate the tool head).

Powder Dispenser Disassembly

Here’s the bottom of the powder hopper. It’s brass and it mounts by threading into the powder dispensing subassembly. The silo that holds the powder is plastic, and I think when it was new the plastic was probably clear. It’s occluded with age. That’s okay. So have I.

This is the powder dispensing mechanism with the powder hopper removed.

Looking inside the powder dispensing mechanism, there were still a few grains of powder left inside from the last time this reloading equipment was used. I’m guessing that was quite a while ago. My Nikon camera and Sigma macro lens do a wonderful job for this kind of photography.

Incidentally, speaking of the last time this device was used…several of our readers suggested that the number etched onto the Star reloader’s base was a social security number. Before identity theft became the problem it is today, it was common for folks to etch their social security number on things to prevent theft. One of our blog readers located the man whose social security number was located on this Star reloader. That owner was born in 1926 and died in 2009. To my surprise, there’s a social security death index where you can find this information. Who knew?

Back to the job at hand: The powder dispensing mechanism is secured to the tool head with two slotted screws. I had applied a bit of Kroil to these screws a day earlier and they unscrewed easily. Kroil is good stuff.

With the two screws removed, the photo below shows what the powder dispenser mechanism looked like. There’s a lower housing, an upper cover, a spring, the two attach screws, and the powder slide. It was all pretty funky when I disassembled it, but I took care of that.

The powder slide is what actually meters (determines the amount) of powder dropped into each cartridge. When the tool head is up (before you actuate the lever), powder drops into a cavity in the slide. When the tool head is lowered (when you actuate the lever), the powder slide is pushed to the left, the cavity containing the powder moves over the powder spout, and the powder drops through the spout into the cartridge case.

Cleaning Things Up

The tube sticking up through the tool head in the photo below is the powder spout. It’s what the left arrow points to. The right arrow points to the bullet seating and crimping die. There was a lot of crud on the die.

The spout was funky, so I ran a patch through it with a cleaning rod.

The bullet seating and crimping die is the last of the three reloading dies. It was super funky. It’s the die that seat the bullet and crimps the cartridge case.

Here’s the “after” photo. I went to work on the die with WD 40 and a toothbrush.

This is the powder dispenser lower housing. It’s funky, too, but just wait.

The photo below shows the powder slide, and it says exactly what I hoped it would say. Note the “BE” on the upper tine, and the “2.7 GR” on the lower tine. That means this powder slide is designed to throw 2.7 grains of Bullseye powder, and that’s a good thing. That powder and that charge, along with a 148-grain lead wadcutter bullet, is the accuracy load in .38 Special. I got lucky; this is exactly what I wanted to see. Note the two rollers between the tines. I’ll explain what they do a little further along in this blog. And yeah, I know, this is another funky piece. But wait; you’ll see.

More funkiness…the powder dispensing mechanism cover.

Here’s another shot of the powder slide and its spring. This is the “before” picture. And that hole in the center? It’s the feature that determines how much powder goes into each cartridge. If you want a different charge on a Star reloader, you need to buy a different power slide. Like I said, I got lucky. This one was set up for 2.7 grains of Bullseye. It’s just what I wanted.

I wiped the powder slide off and, being that it was brass, I wanted to get rid of all the oxidation and then polish it. I was thinking it would be cool if I had some Brasso, but since I’m no longer in the Army I don’t have any. Then I remembered: I have Dillon Rapid Polish brass polish that I use with my Franklin Arsenal brass tumbler, and it does the same thing. I put a little on a rag and used it to polish the powder slide.

Here’s another shot (the “after” photo) of the powder slide.

Note the rollers on the left end of the powder slide. This thing is like a Ducati: It has desmodromic valve actuation. I’ll explain that a little bit further down.

Next up would be the powder dispenser mounting screws. I went to work on them with a Scotchbrite pad and they cleaned up nicely.

Here’s the powder dispenser base and the powder on the tool head.

And here’s the powder dispenser cover, the spring, and the mounting screws reassembled. I used a Scotchbrite pad to clean up the powder dispenser housing and powder dispenser cover, too. They look good.

And finally, here’s the powder hopper reinstalled on the powder dispenser.

Desmo Dispenser Actuation

You might be wondering how the powder dispenser works. It’s really quite clever. When the Star reloader lever is actuated, the tool head moves up and down on the main shaft, bringing the powder dispenser with it. As that occurs, the powder slide translates back and forth as it moves along the curved cam you see in the photo below.

Remember those two rollers in the powder slide?

They follow the vertical cam path shown two photos up. The inner roller rolls along the cam as the tool head moves down, and the outer roller rolls along the cam as the tool head is returned to the up position. This is desmodromic actuation, just like Ducati uses on the their motorcycle intake and exhaust valves. They’re driven open by a cam, and they’re driven closed by a cam. Star could have just used pins instead of rollers, but they went with rollers (a more expensive and more reliable approach, I think). When the tool head moves down, the powder slide takes 2.7 grains of Bullseye powder, shifts it over the powder spout, and gravity does the rest. Take a look.

This is all very cool stuff, and if you get the feeling I’m having a good time bringing the Star back to life, you’re a very perceptive person. If you’re just tuning in to this adventure and you want to see our earlier blogs on the Star reloader resurrection, you can find them here.

Next up? That’s going to be the primer feed mechanism. Stay tuned!

Cleaning the Star: A First Pass

As a first step in bringing the Star progressive reloader back to life, I washed it down with WD 40 and squirted some Kroil penetrating oil on it, but before I did that, I shot a few photos with my Nikon and its macro Sigma lens. These are better photos than the ones in the previous blog shot with my cell phone. With apologies in advance for this bit of redundancy, I’ll start with the “before” photos.

The Star Reloading Machine

Here’s the Star label. They were originally manufactured in San Diego. I didn’t know that.

Star Reloader Parts and Subassemblies

This is a side view of the Star showing the powder container and the powder dispensing mechanism. There’s a lot of dust and dirt on the Star. No rat poop like Gresh’s MGB GT, thankfully.

This is the base plate. It still has several cartridge cases in the baseplate shell holder.

Here’s another “before” photo of the base plate. The doodad on the left is the case feed mechanism. The mechanism on the right is the primer feed.

This is the decapping and resizing die. It’s a bit rusty. I’m thinking it’s probably a carbide die, which means the cases don’t have to be lubed for the resizing operation.

The photo above is a macro “before” shot of the powder dispensing mechanism.

The photo below is a “before” shot of the head of the reloader. It’s the piece that reciprocates up and down with each manual lever stroke.

A shot from the top of the reloader, showing the top of one of the reloading dies.

Cleaning the Star Reloader

Moving on to the cleaning operation, these are the things I’m using initially: WD 40, Kroil (a penetrating oil), a toothbrush, and an oily rag. This is the initial cleaning just to see what’s going on. A deeper scrub of each subassembly will follow in subsequent blogs.

I gave the entire press a spritz with WD 40.

Here’s a better photo of the original Star decal. I’m not going to do a full-blown concours style restoration of the Star and I don’t want to bring the reloader back to as new condition. I like the patina and my intent is to get it working again, displaying the aging that has naturally occurred on an old piece of equipment like this. It’s a resurrection, not a restoration.

The bottom of the press is starting to look better already.

The powder container unscrews from the powder dispensing mechanism.

Here’s a photo of the powder container’s aluminum lid.

Here’s one of the lid’s underside. Note the breather hole. There won’t be any vapor lock on this puppy.

This is the powder dispensing mechanism after the powder container has been removed.

I have a new good buddy named Bruce Williams who restores and sells parts for these vintage Star reloading machines, and I asked him if he could tell me the date this Star reloader was manufactured based on the serial number I found etched into the machine’s base (see the photo below).

Bruce explained that Star never put a serial number on their reloaders, but many police departments, schools, commercial reloaders, clubs, and other organizations who owned Star reloaders applied a property tag number. I wonder who this machine belonged to. It has a history and I’d sure love to know it.

The .38 Special

As I was cleaning the Star, I found I could rotate the shell plate into position so that I could remove one of the several cartridge cases it held. The shell plate rotation is sticky, but I’ll clear that up when I do a detailed cleaning of the shell plate area (a topic for another blog, to be sure). The case was a .38 Special, which told me that’s what this machine had been set up to reload. That’s good. I shoot .38 Special ammo in a couple of guns.

Before 9mm handguns became the rage in the 1980s, the .38 Special revolver was used by most police agencies and pistol competitors. As you can imagine, a lot of departments, schools, and clubs went through a bunch of .38 Special ammo back in the day. In those days, the .38 Special was probably second only to the .22 Long Rifle cartridge in terms of quantity sold, and the .38 Special used to be the most commonly reloaded cartridge in the world. It’s been eclipsed by the 9mm, but it’s still a great cartridge and there are still a lot of folks shooting .38 Special. I’m one of them.

The Model 60 Smith and Wesson

As I explained in our first blog on the Star, a friend of mine gave it to me when I started the Peoples Republik of Kalifornia transfer process for a snubnosed .38 Special revolver I recently scored (I got a killer deal). It’s a stainless steel Model 60 Smith and Wesson Chief’s Special, and it’s a honey. We’ll have a blog on the Model 60 sometime in the near future, and if all goes well, I’ll use reloaded .38 Special ammunition crafted on the resurrected Star.

The Powder Dispenser

The Star’s powder dispenser looked pretty funky, and I could see it still held a few grains of powder when I peeked into the cavity that throws the charge. I applied a few drops of Kroil to the screw heads so it could soak in overnight. The powder dispenser will be one of the first subassemblies I disassemble and clean. Kroil is a penetrating oil; it will creep into the threads so that the screws can be removed without burring the slots. The powder dispenser will be the topic for our next Star blog.

I didn’t recognize what this was (in the photo below) when I first saw it, and it was thoroughly coated in crud. Then I realized…it’s the bullet seating and crimping die. I’ll explain more about this in a subsequent blog, too.

Here’s a close look at the brass slider in the powder dispenser. It’s marked “2.7 GR.” I’m hoping that’s for 2.7 brains of Bullseye propellant, which is the go to accuracy load (along with a 148 grain wadcutter bullet) in the .38 Special cartridge. I’ll learn more when I disassemble the powder dispenser. I’m itching to get into it.

Here’s one last look at the powder dispenser, with the powder chamber mounted above it. In the next blog, I’ll explain how this subassembly works to dispense powder.
