Good progress this weekend. After replacing the check valve in my pressure test rig, I pressure tested the boiler. I had a few leaks around a few of the tubes. They were sealed up with solder and the retest passed with flying colors.
Then I started work on the top cover assembly. I turned the inside of the base enough to get a good grip. Then the part was flipped and I turned the outside of the top of the casting to allow for a good grip.
The top was then bored to take the chimney.
The casting was reversed and the lower part turned to be a slip fit on the boiler shell.
Then it was over to the mill to put in the hole for the safety valve extension. Because of the angled cut I used an end mill for the job.
Next up was the chimney cap. First I turned down one end to fit the chimney.
Next I step drilled and then bored the inside.
The cap was parted off and reversed in the chuck. Then I used the form tool I made for the first version of this boiler to turn the outer profile.
That’s it for this update. I will leave you with a current family pic.
Till next time.
