At the seminars I will discuss the reasoning behind this feeding technique to give you a deeper understanding to experiment from and explain why it really is unthinkable to feed in another way.
I believe only masochists will keep feeding their horses any other way since this is easier (longer feeding intervals) cheaper (no waste) and better for the horse.
I have read that 90% of all domestic horses have some kind of digestive problem and 60% have a stomach ulcer, often without the owner knowing about it. This feeding technique can very well be the solution to those problems and it will absolutely help insulin resistant and other founder prone horses.		  
 

My experiences of "Restricted free choice feeders"
If you want really large storing capacity use a soft net. I Googled "nylon net" and found a manufacturer of the nets they use to protect the public on ice hockey arenas. The thread is 4mm (1/6") and the holes are 4x4cm (1.6"). The net I use for a complete round bale is 3x5m (10'x15').

The ones with a hard grid works perfectly fine but I have had a hard time to get the storage unit to each eating grid to work well if the are to big.
The optimal depth of the storage seems to be 60-80cm (2'-2.5').
I have managed to get working units with a height of up to 2m (7') but then it must be about 10cm (4") deeper at the bottom than at the top and you must toss in the hay by hand a little at the time because large chunks of hay will get stuck on the way down in the storage. It is extremely important that there are no edges that can catch the hay on the inside of the storage unit.
The width of the unit has never been a problem but I recommend at least 60cm (2').
The eating grid should always go higher up than the inner edge of the leaning bottom surface. I have not had any problems with eating grids even higher than 1m (3'). The horses tend to mostly eat down low anyway. The good thing with a high grid is that the horses can eat higher up if the hay has got stuck.

The triangular feeders for use inside a box work best if they are wider at the bottom than at the top.
Don't judge your new built feeder the first couple of days. It is supposed to look like the horses is not getting any hay out the first day. They will very soon learn the technique and if it is too easy they will soon eat to fast again.
Quite a few people have tried with larger holes than 5x5cm (2"x2") in the hard grid because they have felt sorry for the horses but I think all of them have returned down to 5x5cm since that seems to be the optimal size (extremely large or small horse might need different sizes. Not Shetland ponies though.) The eating grid must be really sturdy. I prefer a welded grid with a thread diameter of about 4mm (1/6") but I know of quite some weaker ones that still work.

My experience is that it usually works just as good to fill the feeders with bales as with loose hay and the horses really like to work for their food.

If your new feeder doesn't work.
Wait for a couple of days.
Give your horses small servings on the ground and let there be hay in the feeder too. Usually the horses solve the problem them selves. If it still doesn't work, check for construction errors. Have the hay gotten stuck some where or is it pressed too hard against the grid?

This part of the website contains 9 years of unique experience which I give away for free for the horse's sake so please take pictures of your constructions and email them to me together with your experiences (good and bad). I will post everything on the website for other horse owners to get inspired by.

I would like someone to build a steep (adjustable around 45 degrees) covered slide for small square bales with a standing eating grid at the bottom end.

Good Luck with your construction and please send me pictures together with your experiences for other horse owners to get inspired by.
