        It seems to me that the definitions of a snelgrove board and a double screen board have gotten blurred.  A snelgrove board has multiple gated entrances.  A double screen board has only one entrance.  Both Bob Binnie and Mr. Ed use the double screen boards on a regular basis.  On their websites their videos show how to make and use them.

Thanks jimineycricket, I have watched those videos of the two folks you mentioned. They do always call their board the double screen dividers. I did look up snelgrove board earlier and this is what I found from better bee.  As you say there probably is a difference but better bee says snelgrove invented the double screen divider board as follows.

Adding it is interesting to see Mr Binnie has learned a way to incorporate its use in a commercial setting by using it for his fall splits for one of his examples....


Betterbee
" The double screen board was invented, and first described, by an English beekeeper named Leonard Snelgrove in 1934. This board allows you to make a vertical split with both parts remaining in a single stack after the split. But Snelgrove's invention goes beyond just keeping the two parts together on the same base. The double screen board has three sets of paired doors that allow some of the bees to be shifted between the two units after the split in order to maintain a non-swarmy assortment of the various age-classes of bees in each part of the split."

Mr Binnies' and Jeffs' only have one entrance as I recall as you stated.

Do you use either version of these Jimmy? If so which one?

          Yes, after loosing a hive that swarmed and the virgin did not return from her mating flight.  So, I keep a double screen board with me all the time.   I also use it for just splitting a hive like Mr. Ed does, or for temporarily splitting a hive.   The Snelgrove board gives me a headache trying to figure how to set it up.  :grin:
           BTW, looks to me like the paragraph quoted from BetterBee has scrambled the definition of a Snelgrove and the double screen board.

If the snelgrove, (original design), is more complicated what are the advantages?

Even Jeffs' version and Mr Binnies' version are quite a bit different in design.
Do you have a preference? If so which do you prefer? Is there a particular
reason for this preference?

Thanks Jimmy for your valuable input..

We do double screens between hives if we are running low on equipment. We have had good luck. In Missouri we put two hives together with a double screen to help the heat to get say two smaller hives through the Winter.  Saves a top and a bottom.  :)

don't over think it.  a snelgrove IS simply a double screen board.  the extra "gated openings" are just a convieniance so you don't need to worry which way it's put on the hive.

????? Why is the screen double, how far apart are the screens,  what kind of screen , why not just one screen ,#8, window screen, could a single screen be used for a combine, would the bees fight with only one screen, how can pheromones be spread through two screens. are there cases when you want pheromones to be distributed between the top and bottom boxes, etc.

I've seen bees fight through a single screen several times.  The two screens in a double screen/Snelgrove board aren't very far apart (I'm not sure the exact measurement), but the gap between them allows the scents and pheromones to circulate between the two groups of bees without them being able to reach each other to fight.   
I come from under the hill, and under the hills and over the hills my paths led.  And through the air, I am she that walks unseen.

I build mine with 3/4" Advantech Board or Legacy LP in the Bob Binnie style.  I 'think' Mr Binnie uses a high grade 3/4" plywood. I also use duriable number 8 hardware cloth. Very strong and durable for the long haul.

One other thing I do that I have not seen is I add a run of Titebond III along the edges of the screen for two purposes. To cut down on snag from the cut screen edges and adding strength for screen support..

Also Paus; When making splits with the 'double screen divider board', the bees in the queenless section will develop a new queen with eggs provided. If this new queen fails to come back from the mating flight, for whatever reason the divider board can simply be removed and you again have the entire hive intact. Almost no risk involved.

Another option considering the above case. In case the virgin does not make a successful mating flight, you can add a 'mated queen if you wish', keeping the divider board in place until you are sure the new queen has been proven, laying eggs and developing brood etc. 'Then' you can safely move the new split.

Yet another option, a new mated queen can be introduced in the queenless part, right off the bat, when making a split without going through the waiting period of developing a new queen. With the dividing board installed (for insurance reasons), she will readily be accepted, when proper steps are taken just as in any queenless, mated queen introduction.

Since the bees from the two stacked boxes with the DSDB can not touch, leaving them unable to 'distribute' the queen rite sections' pheromones 'by touch'; Which from my understanding is the key in all above scenarios .. (They can not physically distribute the queens pheromones 'directly' from bee to bee if you will), in the quenless section which sparks a natural desire or need for a queen. I suppose this board DSDB could also be referred as the insurance board... lol

This is also an added advantage of using the double screen dividing board. Thank you for pointing this out.

I use double screens all the time for splits. I make them out of old 3/4 inch feeder lids when they have seen their better days. Its like American express I don't leave home without them. the resons were already posted by Ben

I also found it saves hauling piles of equipment all the time. When the splits are ready you know exactly what you need  next trip to the yard. The other-thing is I can also make early, small 3 frame splits on top of a double due to the heat rise, if they dont take just put frames back in brood box, remove and install 3 more.
