Vermicomposting, worm bin, composting with worms community and forums

I just want to post one simple link if you're interested.Read the bottom of page four.Do further research on your own.Also it depends on which country it's from Thanks.And don't be mad! Just trying to help!

Hope the link works!

:-) sure does, Rock. The link works, Larry. It downloads a 944kb pdf. It's dense technical reading.

I won't comment on the technical aspects. I will just say that personally I have decided to use 3/4" schedule 40 PVC instead of conduit for my 2nd flow through bin. (I'd use bamboo again if it was smoother.) Conduit & PVC are about the same price (both cheap), PVC is easier to cut and is more than strong enough for the bin I have planned.
Rock, on a side note: I was reading about someone who inserted short screws along the length of each pipe and then turned the pipe to dislodge VC. I've never worked with PVC. Can it take that kind of torque/twisting? I'm thinking it might work in my case because each of my pipes are only going to be 30". I'm not sure how hard it will be to rotate each pipe when VC is pushing against it. I'm also wondering if inserting screws along the pipe weakens it enough for it to crack after repeated twistings.
Andrew-Here is a link with a quick glance of what you are talking about
You could sleeve the conduit with pvc.And i think this method would work quite well.You just have to use enough screws.I plan to make one with chain drive,where they all turn together.But i have an idea for a more complicated one using shifting plates.I want to use this method in my 21' long bin.But may just use the breaker bar.I do have to show how to do it one day though.It is cutting edge technology.And something i've never heard done.If it has been done,they keep it secret.This one will work like an exercise machine.Where you just barely pull a lever.If you see this one built before i do,you know they used my idea!
And here is a link that shows him turning the conduit to harvest.
Heck i even found one that shows the tubs i use.But i don't use covers.I may now!
He says tek screws in one of them.But if you look up in the second video,you can see how it harvests.First chance i get,i'll modify my small bin and explain how to do it! I may build it a lot more complicated.But i'll show a detailed explanation on it.
When it cools down,i may build a fancy bin that a wealthy person would buy.I keep most simple so about any one could give it a try.But i want to put on paper one for high school kids to build in woodshop,instead of a checker table.
First comment is that seems like a lot of worms coming out of what seems to be a professionally built flow through. If that's the process, then I think I'd rather make the gaps between each bar larger and then use a long handled fork make specifically so the tines fit between the bars. Rake it a few times and I bet you get as much VC as he did by turning 20 rods on at a time.

As more of an aside, the guy in the harvesting video is one of the folks interviewed for the material in the worm farming secrets sales package. Aside from the strawberry store he's also involved im (owns?) VermiTec, a company that sells worms and worming supplies. I think Mark from Kansas bought some material for his huge OSCR from VermiTec.

This rotating bar method might be overkill for the relatively tiny FT I'm thinking of. I think I'll stick with my original plan and try to move the bin over the grating (like grating cheese) to dislodge VC. The bin will be an inverted 33 gal. plastic trash can. Even if it is 3/4 full of VC, I'm betting I can move it a few inches back and forth. If not, then I'll give the turning bars a shot.
Rock, it's not just the FT design that, but the rate of feeding, temps, etc. that determine whether the VC is relatively worm & cocoon free. I read recently that one of the big VC producers had it down to 5% worms falling through the grating. I think some of us may be expecting too much of our flow throughs.

Your design makes more sense, but I'm "constructionally-challenged". It would take me too many frustrating hours/days to build it. Even cutting a "big round hole" in plywood would be a bit of an adventure for me. lol. Wood channels with ball bearings would be like an Everest expedition. I considered salvaging the metal rails & wheels from a filing cabinet, but that might not hold up so well in an outdoor bin.

Thanks for the ideas. I'm sure someone here could put them into practice.
Not lead, but Zinc. (galvanize - to cover (iron, steel, etc) with a protective zinc coating). The zinc 'rusts' before the iron will and protects the item it coats. Not sure what the effect would be on worms but probally negeligble as they are not in contious contact or in circusatce where 'rusting' is taking place since is only being used for filtering the VC.
You could do that,or get the self tapping screws with the large heads.It would cut your build time way down.I'll see if i can find them in my garage and post a pic.
Thanks for finding that Larry. Sheesh, I hope that lead is illegal in galvanizing in NZ, I expect it would be.

We have traditionally mostly used galvanized corrugated steel roofing, and use a LOT of roof water for house supply in off-grid areas (it's one of the most common sources of drinking water) and also used to use a lot of galvanized corrugated steel water tanks. (Today they're more likely to be plastic)

In NZ we're pretty hot on lead in general - you don't see lead flashing on roofs there now like you do in the UK, and lead pipes have been banned for decades. (My last place in London still had the Victorian lead pipe bringing the water to the house. I was horrified when I found out!)

Having all our anti-lead laws but allowing lead in galvanizing would be nuts.
Supposedly New York still has a lot of lead water mains.We were replacing lead pipes at the water meters at the beach in Neptune Beach,Florida.I doubt we replaced them all.Most of the galv.water fittings you buy in the stores seems to still be made in China and India.China still uses lead in their paint we get.Even in baby toys.I would not trust their galv. at all!
You can't trust anything from China! Look at what they did to their own little babies, they added melamine to the baby formula. This fools the tests to make it seem as though there is more protein in it then there really is. Many little ones died, many others are damaged for life. Such a shame. This of course is after they tried to kill all of our furry friends using the same method.
