I recently bought a non running Aster Schools class and started dismantling it to get it running
Here are some pictures of the process

Boiler removed

Cylinders taken appart to remove dry gaskets and graphited yarn
![Image]()
I replaced the torn gasketd by ones made from a sheet of paper and graphited yarn has been replaced by teflon tape
Please pardon the poorly cut gasket, it really looks bad on photo!
![Image]()
Assembled and tested on air: (nearly) no leak!
![Image]()
The right one is butter smooth but the left one binds...
![Image]()
The nut is not aligned with the slider

I paused this waiting for a solution (thanks Ryan from tr3services and Geoff from rushford barn models for responding to my inquiries)
I then worked on the tender and spirit burner: unmout and clean, replace dry gasket with a silicone one

Then, fire! I have to adjust the wicks to get blue flames
