Last week I spied my favorite neighbor out in his garage. I never know what he’s up to and this time was no different. He had this cast copper blue whale weather vane lying on the bench along with an assortment of copper pipe of all sizes. Mixed in was different sealed bearings. He had been given the old weather vane by his neighbor and he was trying to figure out how to resurrect it. As you can see by the pics it’s been out in the weather for decades and the patina is wonderful.
The base of the vane was just a stud, no threads. And he didn’t have the correct die. I did. As we tried to figure out how to make this thing we started drawing it out on a paper towel. I didn’t see how he was going to just assemble this without some machining and he admitted he had been hashing this over in his mind for days and was wishing I’d show up. I had a brass shaft that had been machined for a boat that went from 1 1/8” down to 1”. He had the bearings.
So we agreed it needed to have a spindle for the bearings, threaded on the end to screw onto the soon to be threaded stud sticking out of the whale base. It would have a copper pipe cap, drilled and cut down so it would fit over the tube to seal out weather. The tube had to be bored for a slip fit for the bearing and have a shoulder in the bottom for the bottom bearing to register against. It also needed 3/4” NPT on the bottom of the tube to screw into mast it would be mounted on. It also needed to be cross drilled 5/8” for the copper tube that would be what the cardinal points were mounted to. This was a bigger challenge than I thought, mostly due to my inexperience. But it’s done and he’s happy. When he gets it finished and mounted I’ll post the final pic.
