After the epoxy pour, what did you do sand or flatten it? It looks very well done.
So the epoxy was poured so it stood 'proud' of the wood. What I 'wanted' to do was run it through a shaper or a belt-sander table to cut back. BUT I made the mistake of putting in brass pins to show the locations of forts and battles on Lake Champlain between F/I wars through the War of 1812. Noone would 'touch' putting it through a blade or belt with brass on the wood.
So I set it up on the mill and using a facing cutter (for metal) and in several passes shaved the epoxy off. I had let it harden up for about 10 days so it was really rugged. It cut beautifully... just like soft metal. I stopped just short of the wood and then finshed with palm sander using 80 through 400 grit. Then hand sanded the epoxy up to 1000 grit. Then finished with Minwax Spar urethane aerosol, about 10 coats. Towards the end, wet sanded and got all the 'white poweder' out of any tiny grains. Then coated a couple of more times for final finish.
IF there had been no brass in there, anyone with a shaper table or a belt sanding table could have run it through a few passes and cut it back dead smooth in seconds. So if you want to put in pins or metal... do it last!
Note that there is no 'lake/swamp' exactly where the swamp is on that map... that was a nasty spot in the board, but I sort of fudged it and lowered the Missisquoi swamps and the swamps on the Quebec Border... they're a bit 'south' of where they should be. But the effect is the same...
In sunlight the epoxy is really cool!
One other thing I did was before pouring the epoxy, I painted the wood with 'depth' lines darker in the lower areas, white around the shore. It really added to the 'depth' effect.
I just did it because I saw all these YouTube videos and postings here and said... I want to try that. Glad I did. It's a really cool table. Everyone should give it a shot!!
