Procor 3000 cf Sodium Chlorate hopper - 3d printable

Procor built more than 1,300 aluminum covered hoppers for hauling sodium chlorate dry crystals. Over 95% are used in paper manufacturing (bleaching agent). The remainder are mostly sent to beverage facilities for sanitizing equipment. Both industries I plan to add to my RR.
I’ve built 2 versions, One with retractible safety rails and one without. The files are shared on Printables. https://www.printables.com/model/1626905-procor-3000cf-sodium-chlorate-hopper-for-your-gard



Decal sheets in PDF format are provided as well

Here is the Cricut design project file for the Anti skid patches. https://design.cricut.com/landing/project-detail/69c6c26bf52b03855e54d913



I fashioned the safety rail sections from brass rod.

All parts printed in Polymaker ASA except the detail bits at the bottom which are Siraya-Tech tough grey resin.

For added weight, I made inserts for the hopper outlets to hold a stack of pennies.

Looks great! I love all the details, end platforms.

Only 1298 to go.

Thanks! A few details I’ve added to mine are not included in the print version. These “patches” on the sill are styrene sheet.


and the brake lines are 2mm styrene rods attached with brackets made by drilling a couple holes in styrene.

Not “Super detailed” but I felt they were needed. :slightly_smiling_face:

Absolutely beautiful !! And your willingness to share the print and decal files is just awesome. Great work!

Wow Dan, those look amazing!
What a great idea using a roll of pennies for weight.

Do you use your mini torch to solder the railings?

Another gorgeous research, design and modeling effort, Dan! So many excellent details, and the decals are, as always, wonderful

I too am impressed with the pennies for weight. Easily adjustable, uniform shape (unlike many fishing weights), and they only cost, well, pennies.

Thanks! Yes, I was going to use a soldering iron but the little torch works so much better! I cut a shallow X channel in a scrap board then:

  1. Placed and taped the brass pieces in place.
  2. Added a couple drops of liquid flux to the joint.
  3. snipped a tiny bit of silver solder and placed atop the joint.
  4. lit the torch and slowly brought it towards the joint.
    Worked like a charm. Little to no clean up. (filing).

That is clever and the results look great. I might have to try that the next time I have railings to make.
