I swapped vehicles to drive to my workshop today because the automatic park brake on my BMW X5 would not release. And in swapping vehicles I forgot to take the plans for the projects, so I could not do very much.
But I did set up for the remaining boiler wrapper perforations.
The boiler is ready for drilling the multiple holes. It is parallel with the mill bed, in 2 dimensions. But without the plans I could do no more. Ready for progress tomorrow.
Note the rectangular cut out for the ash pan.
I had previously cut the 44 firetubes from 3/8″ copper pipe. Today I spent some time squaring the ends and deburring them. No photo.
It is cold and wet here in southern Victoria, Australia. I had my wood burner going in the workshop, and spent some time hooking up an industrial gas blower heater, for an extra bit of warmth.
