Looks awesome. With your metal working skills I am sure you could insert an edge if you wanted. Otherwise, clean up the cut, and start sealing that bitch. I believe most use epoxy and then maybe add a poly urethane at the end. Evidently the edge will soak up a ton of epoxy. I am sure you know this, but just in case. Use a flexible epoxy with as low as a temperature rating as you can find.
Thanks killclimbz. I was contemplating putting an inside metal edge, but haven't researched it enough yet. I might leave that for a better board that i'll split if this works out good.
I sanded the edges and beveled the base to a 45 degrees. Pictures don't show anything, so I didn't load those. Here are the tips rounded.
