New Bench top

[Brett57]

Advice please, I have not built a dedicated bench before. 40 years teaching I had no need.
I have been thinking about what to use verses time vs cost.
I have what I think could produce a good solid top.
A solid laminated Tasmanian Oak 40mm thick door. It is not a solid core door but solid Tas. Oak. I was thinking of laminating this on top of a 40mm solid core door which I also have.
this would give me what I think would be a very stable 80mm. thick top.
I would then edge front, back and ends with Tas Oak.
All this would sit on a hardwood frame.
If I did go down this path would people think I would be best to glue the two together or simply screw them together from the underside ?
Any advice will be appreciated.
cheers

I’d be screwing from under but mark top where screws are so you can put your dog holes elsewhere. Screwing makes it so you can replace it when it gets battle scarred.

Scroll down a few posts to scrap workbench and watch the video. You'r plan is pretty much the same as that guy does.
