The bevels were done so when I glued the 2 pieces together they would follow a 10 radius to go around the boiler. I also chamfered the 2 edges to simulate a vee into the wood like what was on the tongue and groove joint. I glued up enough to get 1/2 way around the boiler. I didn't do them all as I might have to make some of them narrower so when I get to the last piece it will fit in the bottom ring tightly.

该bevels 人这样做，当我胶合板2件一起，他们会按照10 半径去靠近锅炉的，我也削2的优势，模拟VEE的进入木材一样，什么是对舌头和Groove联合，我胶合板直至足以让1 / 2的方式靠近锅炉的，我没有这样做，他们都为我可能会作出一些他们窄，因此，当我到了最后一块，这将适用于在底部的环紧紧。
