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

[@joelongstaff7601]

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.

[@kammer007]

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.

[@AndysMachines]

Yes, I don't know why, but the one I used originally didn't seem to give the correct results and I also could not figure out how they'd arrived at the formula they used.

[@kevcat8655]

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

[@davisonnyatinyirenda4626]

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

[@radriand]

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.

You are a génius man !!! I realy look for that since years ! Thank you very much !

[@MostlyPosative-nj5ex]

I made one years ago. I didn’t know the math and I couldn’t even find it probably due to the words I Googled. I bought big washers from the hardware store, cut them and welded a few together. I then stretched them out and tried different round stock to find what fit. After that I drilled out the washers inner diameter larger to use a larger rod in the center. I then sanded down the outside until it fit into the pipe. 2 different approaches with the same results.

Awesome. Just a note from a farmer: the flighting on auger screws are rarely seam welded the length of the helix. More commonly I see a weld stitch once per turn of the helix. Good work anyway.

[@dannywilsher4165]

I made one of these augers and drilled a water well with it. I used a 1/2 inch drill to turn it to a depth of over 30 feet...

[@AndysMachines]

I always wondered how hard this would be. Unfortunately where I am you need to drill to 200 feet to hit the water table.

[@dannywilsher4165]

@@AndysMachines That depth would definitely present more challenges for sure. I used 3/4 pipe and had to screw it together and unscrew it many times as I was extracting the dirt out of the hole...

[@AndysMachines]

[@jhsevs]

0:24 I hate to be that guy but this is not a spiral! It is a helix, and almost everyone gets that wrong😀

[@AndysMachines]

You're right of course. Yes people tend to use the two terms interchangeably, but there is an important difference. Even manufactures of drills and taps describe them as having 'spiral flutes'.

[@Raul28153]

you could do it the old fashioned way. Hammer and anvil. Thin the outer edge and the steel strip curves itself into the spiral. Same tech approach is used in large production; two conical rollers do what the hammer does.

[@AndysMachines]

You win the prize! I'm surprised nobody got it sooner! Yes, the third way I was thinking of was just to take a flat strip and twist it into a spiral using a blacksmithing or similar method.

[@mohammedazaroual5925]

That,s also a good idea to twist a flat iron.both of your ideas are good.thank you so much. With youtube we learn more.

[@eugenevoltage1654]

The third way - Screw cutting? I saw a video recently where a guy made an impeller (not sure if functioning though, the flight ratios looked a bit weird). He made about 1000 screw cutting passes at very low revs, very high travel.

[@AndysMachines]

I think screw cutting would come under the 'start with a solid bar and machine away material' category. I was actually thinking of a different method entirely, not involving machining or welding (though you may want to true it up in the lathe afterwards). Or casting, so I guess there are at least 4 methods and probably others I haven't thought of, I suppose you could directly 3D print it in metal too. Yes, I saw that video too, quite spectacular! The gear ratio he was using to drive the leadscrew was insane! I would never attempt to gear up the leadscrew so high, I'm surprised he didn't break something. If I were attempting it that way I would drive the leadscrew from the far end and use the gear ratio (in reverse- as a reduction) to slowly drive the spindle. But then I already have a stepper motor on the far end of my leadscrew.

[@spehropefhany]

The insane Russian guy, yes.

[@supersherpa2011]

@@AndysMachines One quick question, your formula is the ID+R and OD+R or it's something different?

[@AndysMachines]

@@supersherpa2011 It's just the ID of the helix (diameter of the rod it will fit on) and the OD of the helix (total outer diameter) and the pitch determines how much it is stretched out.

Wow, this is amazing too! I never realised this would work, lovely fit too

Hi I don't have the tools to making that but I found that there is A Drill Bits named "AUGER BIT" I think it is same shape Can I use them to make "filament extruder" and will it do the same job ..thank you

[@AndysMachines]

Yes, people often grind the screw point off an auger bit and use it to make a feed screw, however it's not really the right shape for an extruder screw, though it may work acceptably for your application. (I have another video where I machined a compression screw for an injection moulder, it's a bit more involved)

What was your method for stretching the helix evenly? I'm having a tough time with gr8 washers. Thanks!

[@MichaelScottPerkins]

This is a wonderful video!!! I have a question, and I would be extremely impressed if you know the answer. If you look inside the feed tube of a meat grinder (mincer)... the auger spins inside the tube, but the tube itself, also have a... "sympathetic"(?) spiral shape protruding from the walls of the tube. I imagine this has something to do with the fact that the material being transported along the auger... i.e. meat... is a soft amorphous material, unlike dry stuff like... corn, or whatever. However, I am only guessing. So my question is... A.) Why do the walls of a meat grinder have "rifling" along the sides? B.) Since the spiral inside the tube is protruding, i.e. not cut into the wall, but coming out from them... how would you accomplish this?

[@AndysMachines]

Thanks! As for the meat grinder, I've never looked inside one and I would be guessing, but could the spiral fins on the walls provide some of the grinding action? ie. a chopping/shearing action between the wall and the auger? If that is what they are for I would expect the number and or pitch of the fins on the walls to be different to those of the auger to even out the grinding action. Meat grinders are probably cast with the internal features in place, but then you have the problem of how to make the pattern with the internal spiral!

[@chriskwakernaat2328]

my guess is mixing the meat ?

[@roseknows702]

Wrapping a string around for the inside diameter?

[@wickedprotos1937]

[@Critical_Path]

Excellent video and cool idea. Encyclopedia Britannica didn't come through for you, so you made your own formula... Fantastic. Also, what is the music in the video?? Great choices

[@stoneomountain2390]

Saw a vid where a guy made a jig, welded one corner of a flat bar onto a shaft and then just proceeded to turn the shaft.

[@AndysMachines]

Yes, that's a really good way of doing it. If I were making more than one I would probably put in the extra time to do it that way. Once set up properly it produces very consistent screws, it does take a lot of turning force to rotate the shaft though, it can be done in a full size lathe in low gear, but not sure my small bench-top lathe would do it.

I want to make 1 can fit in a two inches pipe with a half inch seal as the middle how do I work out that

[@dadoVRC]

Hello, I'm Davide from Italy. I made an auger for the same purpose of yours, I make an injection machine (I'm developing a Precious Plastic workspace) and I want to make it self loading. Since I'm a lathe machinist and I'm allowed to make my parts after the working hours, I lathe machined it from an aluminium bar. Now, I have some issue in dealing with the shredded flakes, the longer ones tend to get caught between the auger and the tube. I also filed away the part as you do on yours, but the material get caught just after the removed part and starts to rotate around the auger, stopping the feeding action. My question is, how much play did you leave between the auger and the tube. I left something like 0.5mm on the diameter, and I'm wondering if it is too little space, since the shredded parts, for example HDPE bottles, are thicker than that. Probably machining the tube from 25 to 26mm ID can solve the issue...? Thanks a lot!

[@AndysMachines]

I'd aim for a bit less than 0.5mm if you can, maybe around 0.1mm. But I had the same problem, if the thickness of the shreds is similar to the gap around the screw they will always work their way in between, this is why commercially they use pellets.

[@dadoVRC]

@@AndysMachines Thank you! I decided to try to enlarge a bit the diameter of the tube, I made it 25.5mm for the moment, and I made the surface a bit rough (for sure rougher than before, it is a seamless rolled tube), I hope that help to let the screw rotate with the shreds stopped by the roughness. Finger crossed, I'm testing it in minutes! 😂

[@Tripolite]

Thank you!
