Hi all.

I am having the same issue as the OP. We have several large tools machined from several layers (10+) of MDF, and we are having issues with the final parts showing the seams.

The tools were made by gluing the 0.75" layers together with Titebond II, clamping overnight, then machining the next day.

We have tried sanding, Bondo, cyanoacrylate, screws, wax paper...

Any suggestions?

Does anyone else use layered MDF for large tools? If so, what glue do you use? Do you have these issues? Tips on solving them?

Can anyone recommend some sort of coating for the tool to avoid this sort of thing, as well as to increase the tool life?

I'm new at this, so please, don't hold back any suggestions just because they seem obvious to you.
