Grain pedestals out of twin wall.

[Sprayer 1]

We were thinking of trying the above as at LAMMA there were some pedestals that looked just like twin wall drain pipe. I thought i could tape some soil pipe in the top for the fan to sit in but cannot decide what i could make the base from and how it could be attached . Advice welcome thanks.

Everyone says they're not as good but how about some ply and tek screw some builders band.

You should be able to get a adaptor for twinwall reducing. Gibbons may sell their adaptor separate.

I just bought second hand metal pedestals for £50.

I use a 1m perf at the bottom, which is buried first, then a 3m length of solid out of that. Just be careful not to wack it with the bucket when heaping up. Stick a fan on the top and rotate the fan each few days between the pipes.
ive got a 6” to 4” reduction fitting which joins the fan to the pipe perfectly.

Did you buy the ones off grainman? Looked at those many times but everything is always the other end of the country to me. Will look up what builders band is and give it a go.

How do you stand them up when putting the grain around?

Grainboy yes. I got lucky as he had a lorry coming 20 miles near me that week

Do you really need a base if you use 260mm twinwall anyway?

So is the 4inch twin wall 6 inch outside diameter?

6” stands up no bother

Done it many times, per pipe cut into lengths slot a few more holes with grinder. Europipes at Shipston do the mid way reducing cones to reduce to the 6 inch top section

There is a thread omewhere on here where someone puts drainage pipe in using a vacuum AFTER the shed has been filled. Looked to work well, cheap to do, and could put plenty in the shed to account for the smaller air hole area.

i believe @Badshot is the man

I made some. And they were relatively unsuccessful, until I brought metal ones at a farm sale! 3m in length, perforated at the bottom with a grinder or drill. Screwed down to a round piece of plywood about 2ft in dia, with 4 pieces 4'/2' timber supporting the pipe, screwed to the circumference of the plywood at 45 deg to the twinwall.
Worked well....but don't leave too much of the twinwall sticking out of the top of the heap unsupported with the weight of the fan on it. It'll fold over, and also they don't like being touched by the grain blade. They snap off. I have also done the hover and pipe trick. Solid soil pipe pushed into the heap while the grain was sucked out of the centre. Then pop some twinwall down, and pull up the soil pipe. Not particularly easy, especially if the heap is hot!!

Sorry meant to say successful. Sausage fingers.

If that doesn't work just search perforated twinwall grain aeration from badshot.

It does work.
Don't worry too much about the lack of perforations, the end of the pipe is open which means it sucks from the very bottom of the heap.

The only issue I've had so far is my thermostat packed up so the fans ran permanently, that ended up with a crust on the top.
Wizzed through twice with grain stirrer and all was good again..
I've now got some much better temp controllers to operate them, very cheap, and very good.
Going to get more fans this year so I don't have to keep moving them , I only use the little ones.

You shouldn't get a crust if you're sucking from the bottom. Even if the fan is on for too long. Are you sure you're not blowing air in? Then you'll get a crust. I did accidentally yrs ago.

It was recycling the hot air, not enough ventilation in the shed, a crust definitely formed. Could walk across it.
Last winter was a bugger, the big store fan hardly ever came on as it was too warm and moist.
I only went in when the temp was supposedly suitable to cool, wasn't till I was about when it was far to hot that I realised things weren't quite as they should have been.
New controllers will stop that.

I have done a bit of research on all this recently and I think buying new pedestals isn't that bad an option when you consider the value of the grain etc.

Spaldings sell a complete metal pedestal for £162 and you may be able to get them cheaper than that. Or just buy the perforated section at the bottom for £50 and then source a reducer from ebay and then use plastic soil pipe on the top. Or get a quote on plastic bottom sections somewhere.

Having read old posts on the forum and having weevils last year I have realised that I wasn't putting enough effort into getting cool quick enough. You can get fans for £300 and I actually think this is a good investment to just to keep everything right even if only used full bore for the first two weeks.

I've found fans for circa £100, plus fitting a flex and plug.
The beauty of vacuuming twinwall in after filling is there's nothing to hit while filling the shed.
Plus I put them a lot closer than pedestals which gives, much better coverage of the shed.

But surely those smaller fans move less air meaning more fans or more moves?

I like the idea though and I ordered one of those temp controllers you had off amazon to try out. Not sure if will work with a 1.1kw fan though.

When vacuuming in if the pipe doesnt hit the floor does the fan not keep sucking corn up
