Replying to Another box top sheet question!

Yes I did use the search bar.
And, yes I asked to be in the build a jib cult, NO invite.

I built the box and capped it with a 3/4 inch plywood. It is solid.

Now looking to put a top on it.
Found some Lexan really cheap, but here are the questions.

They only come in 48" long sheets, can you connect the sheets? Obviously one continous sheet would be best, but I think it will cost alot more!

How thick should the sheet be (1/4"?), what are others using?

Any help would be Great!
