Sparging lid

[Zee]

I am looking for something that can act as a lid to go on my mash tun when I am sparging.

I have a spinning arm to secure through the middle and would like to cut a section and add a hinge to be able to view inside the MT.

I have a 10 gal Igloo as a MT which is about 45cm wide.

Can anyone recommend something I can easily buy and convert, or something already custom made.

Thanks
Z

What about an piece of Perspex? Relatively cheap, you be able to see through it and it's easy to work with, i.e modification

Would the perspex mist up?

probably,

why lid anyway, your sparge temperature will warm the tun/mash up as it flows, if its a cold day up the sparge temp a degree to compensate if you think its necessary
