Should the auger stick out over end of the tube? Any way to use PVC instead of steel? Just curious.

Yes, the auger should stick out about 2 flights. To far and it will grind coal. Feed pipe-Schedule 40 2” pvc works good. But may not last as long as metal. I’ve used this on my EFM, looks like you have a different machine though in your profile. Scott

What kind of stoker are you running? You don't have any stokers listed in your profile.
As long as the pipe is not going into the fire chamber, PVC could work.

I never tried it with a Van Wert but I can't think of a reason PVC won't work for the bin pipe.
It should be 2.5" schedule 40.

I'm not trying to be cheap. It just seems to me the coal would move easier through PVC. Less friction?

I don't think there would be any less friction. In fact the PVC will ware quicker leading to more friction once it wares. On the other hand, if you shut down in the Summer, it won't rust during the off season.

Maybe not but when you're cheap and you win out it sure feels good! No shame in being cheap! You think we all burn coal just for fun? Wait...don't answer that....

LOL, I'm probably fussing over nothing. Its just that my auger is out a bit over the end and my pipe is pretty like pitted. Not real bad, but rough. It will probably clean itself after a little usage?

If the pipe is pitted it would replace it. Stainless will last a lifetime, but aluminum works pretty well also. PVC works fine, but it doesn’t last more than a few seasons.
Steel tubes work good in a dry environment with dry or oiled coal. Mine got pitted inside and was causing the coal to grind.

Yep, that's what I was thinking Rob. This tube is pitted pretty badly. I'm sure it would grind coal. Thanks guys.

Van werts and Allen stokers (like mine) use the same sizes screws and auger tubes. Don is right 2.5in sch 40 pipe. If you want to spend the extra money 2.5in sch40 stainless steel is the way to go that should last a very long time as well. I just replaced the tubes and screws on mine it runs so much better. any where from 1.5-2.5 flight (full spiral) sticking past the end of the bin tube is good for the auger.

Alrighty, so I bit the bullet and ordered a pc. of stainless. Should be here fri.? My tube has about a 8" or so cutout at the hopper end. Is this correct. And as I understand it the auger should stick out past the end 1 1/2- 2 inches? Also I've seen some pics that show small holes in the upper end for some reason. Sorry for all the questions but at what this hunk of pipe cost I don't wanna screw up....

This is a picture of the flight on my bin screw. (I need to lengthen my bin tube to make only 1.5-2 flight sticking out)
Member Stokerdon knows alot about van werts, he should be able to point you in the right direction about cutting the bin tube.
Hope this helps
