Best material for auger centre shaft

[pressbrake1]

Ferrobide for weld on tungsten carbide bimetallic choc blocks.

Armacarb for braze on choc blocks

No this was a braze with carbide lumps in

Oh yeah I know the stuff, one brand is ColTung.

Crushed tungsten carbide in nickel boron matrix.

Thats basically what the wire hardfacing rope i suggested above is.

its snapped a 35mm solid bar so i assume would be to much stress on a centreless? i thought they were mainly used where slight bends were needed?

I would be looking closely at the clearance between the flights and the feed chute, making it stronger is not really the answer if you can already hear the auger drive motors straining. Augering chip up a tube should be effortless. Almost needs a softer wiper type material on the outer edge of the flights to keep the chip in and not under the auger.

Most of the reason it snapped was down to worn/bent flights increasing the power needed to turn it coupled with the centre shaft wearing down from 35mm to ~31mm over a few years-design was pretty trouble free for the first few years of its life so im happy the basic pitch etc is right

Anyway new shaft made from en16 and flights fitted fingers crossed i wont be seeing it again for a few years now its fitted

Where did you get the flights rolled?

If the auger had that much wear the chute is probably a tad thin by now.
