Step 1: Get a Free Table, and Some Wood Scraps
Step 2: Slice Wood Into Pucks to Put on Surface
Step 3: Make a Wood Border
Measured the length and width of the top. the piece of scrap trim I had, wasn't quite long enough, so I sliced it in half lengthwise. this particular table was 30" by 17.5".
I would have mitered the edges but without a miter saw it would be tricky to make the edges match. so I lapped the edges instead with the band saw. I measured the thickness of the trim boards, and added that to the length of the table. If I were to do this again, I would have added twice the thickness to the to longboards, so that the ends would overlap same way on both sides.
I screwed the trim boards together. Because they were so thin, I drilled tap holes for the screws first. I also drilled a countersink inset so the the screw top would be flat with the surface of the wood.
Step 4: Glue Trim to Top of Table
I used a glue gun but because of the size of the length of the trim, it was difficult to put enough glue down before the glue started to harden. If I were to do this again, I would probably use a generous coating of wood glue. And have taped around the sides with blue tape to seal it, while it was still dry. It was leaking when it was wet, and once it's leaking it's very tricky and messy to seal the leaks. An ounce of prevention is worth a pound of cure.
Step 5: Arrange Wood Pieces
Another thing I would have done differently, is glue all of the pieces down. I didn't have too much trouble with pieces floating, except for a couple of small pieces. Hot glue would work fine for this. They just need to be tacked to the surface so they don't float away when the resin is poured on them. It's easy to tack them down after you have the pieces arranged, just lift each individual piece and put a little glue under it.
Step 6: Mix and Pour Resin
I ended up using half a gallon of resin to cover a 30 inch by 17 inch table top. I could have probably put more resin on it if I had made the trim higher. That's another thing I would have done differently. Then it could have had a really smooth surface, if the border were high enough about 1 inch high, then there would be about half an inch above the wood pieces that could be just resin. I would do something that high, in two layers. It took about 2 days for the resin to dry completely, so I would wait two days and then put a second layer on the top.
