Making the Mounting Surface Flat.
A trick for making the mounting surface perfectly flat:
- Get really close, then wax the bottom of the mount.
- Spread some thick epoxy (go for mayonnaise consistency) where the mount will sit.
- Set the heavily waxed mount down in the epoxy so it squishes out around the base.
- Slowly back away.
- Let the epoxy cure, usually overnight at least.
- Come back, and pick up the mount.
The wax should allow the mount to not stick to the epoxy, and when you pick up the mount you should have a perfectly flat base that fits the mount exactly, guaranteeing that you don’t have any imperfections or gaps under the mount. You can clean up the epoxy a bit if necessary with some sand paper, but don’t mar the flat surface if you can help it. By the way, you can use other fillers than epoxy, but be careful not to use something that will compress or break off bits when the mounts load up.
