I lost the removable bottom board for my flow hive and need the exact dimensions to make a new one. I do not want to disturb the colony by removing the brood box to fully expose the bottom for measuring. Thanks.
ok, so you need the dimensions of the corflute insert? Someone on the forum should be able to provide this for you.
Do you mean the corflute slider board. If so just measure across back slot to slot and allow 1/16" clearance on either side.
Push it in and cut off the excess.
If your talking wooden bottom board with mesh floor that’s needs a bit more work to measure and make.
You won’t disturb the bees just measuring without moving the boxes.

The dimensions for the coreflute board for the WRC and pine box are different. Probably just the width though. I can send you both sizes tomorrow morning, no big deal. (E Australia time). Unless somebody does it before.
It’s for the coreflute board. Unfortunately the way I designed the hive stand I can’t get close enough with a tape measure to get a accurate measurement.
Hi Helmut, I get approx. 308.5mm wide X 475mm long. Mine is the Cedar one.

Still love ya. 
Thanks Dan. You saved me a lot of trouble with disturbing the colony. Summer now but when the weather turns cool in a couple of months I’ll want to close the bottom.

I’ve discovered I have no corflute for my flowhive 2, bees arriving next week. Did you manage to get one and make it to dimensions? Can you pass them on. It actually confuses me , I read so many opinions on it. There is the screened bottom board and a tray fits under it. What’s the point of the tray if I slide corflute on top of it. ? As nothing will be able to drop through. ? Isn’t that what’s meant to happen. ? Or am I supposed to close it off to keep heat in and bugs out. What the purpose of the tray then ? Sorry. Navigating this site for the first time and latching on to someone with a similar problem. 
I don’t know what the tray is that you are talking about.
The corflute slides in either of the two slots under the screen in the bottom board.
Doesn’t look like coreflute is used on the Flow 2 only a multifunctional tray.
@Jacque101 the tray is used for pest control mainly, SHB and varroa.

I should have known that.

Definitely no coreflute slider comes with flow2…Just the tray.
@K9GSD, I make my bottom boards the same dimensions as the supers. Therefore they have a flush entrance. I make them all with solid floors. I wouldn’t use a mesh floor.

Thanks so much for your advice. This corflute business has had me stumped ! So ok. I don’t have it or need it because I have the tray right ? I was reading so much about having this corflute up against the tray so the girls can eat up any spilt honey … so they won’t be able to do that with this tray method and their floor with be the grate with holes. Yet I read around that solid floors are better. So that confuses me a little. . Think I’ve got that straight now. And I’ll keep the vent in the closed off position . And clean the tray every couple of weeks.
