Making an Auger (feed conveyor) from Washers ...and mathematics!

The pitch of the screw and circumference of the circle on the diameter make two sides of a right-angled triangle. Solving the hypotenuse with Pythagoras gives the the length of the helical path at this diameter, knowing the ratio of the inner and outer diameters allows you to calculate the radii of the annular ring that fits both helical paths.

Sir I just found your video and I had to write you. My daughter dose pottery and has been telling me she needs a pug mill, no not the ugly dogs, to grind up scrap clay and I had no idea how to do it. Now with your site she just might get one for Christmas. That saves about $4000. Thank you so much. Keep posting and God bless.

It's so generous of you to share the spreadsheet. You are clearly a good man.

These calculators are all over the internet for calculating the flighting for screw augers yet they don’t match your results. Obviously yours is correct. Excellent video! Thanks.
-
Great work, and sharing the spreadsheet like a boss. Well done, sir.

Namaskaram Dear sir, this video shaved me from confusion and faulty formulation as well as resources with time in R&D work. your spreadsheet is so precise, effortlessly we can find the exact OD & ID of the washers to make augers (screw bush). Thank you for your initiatives to this video and spreadsheet broadcasting.🙏

Simple and straight to the point. Well done sir. I need to produce conveyors for my project. With this video am almost there. Thanks alot.

I love your work and calculations!! Thank you!

Excellent video thank you, a slightly different take on a screw conveyor. We often make them from a single piece of thin flat bar put in an appropriate round tube. One end of the flat bar is clamped in a vise and the other end twisted with a monkey wrench. The tubing helps keep it linear as you twist. The end result does not have the center spindle and hubs or stub shafts need to be welded on, but it works very well for granular delivery or chip conveyance.

Really good info, well presented with a real professional voice. Thank You
-
Very ingenious, like the way you rotated the auger while welding it.

¡ Genios, Thankyou VM !. I was breaking muy head many times to make something like this !. Health for you and your people. Greeting from Córdoba, Argentina

Great Video!.... and the spread sheet is fantastic. I used it calculate ID and OD to help manufacture a wood chip auger in a mill.
-
Nice idea and project. Thanks for posting this. Thumbs Up!
-
Awesome Spreadsheet Andy, I used it several times now for different sizes and it works great. But I think I'm gonna send you a step drill for Christmas...lol
