Peter ( repairing two La Pavonis

One of my La Pavonis swiveled on its base which needed to be fastened and the other one had a leak in the sight glass. All in all a fine reason to visit Peter van der Weerd of again!

First Peter admiring Tije's wooden 'cooling' ring

Opening up

Inspection of wires and internals. This La Pav still has the original p-stat

Replacing old gasket. Heating element in perfect shape.

Setting the boiler on the custom made tool to unscrew the bottom ring


Another gasket ready to replace

Three new gaskets

Cleaning the base.

Fastening the boiler to the base again


Reconnecting wires and pipe
Meanwhile, as the one La Pav is heating up to see if anything leaks, repairs on the other machine, starting with the sight glass:
Replacing the seals on the sight glass

New seals

Nylon gasket will get a rubber seal on top

Rubber seal on top

After the metal parts are in, the glass tube is pushed in from above

Tightening the seals

Pressure gauge back on

Pressurizing the boiler through the steam tip

Checking for any leaks, tightening the seals some more

Replacing rubber seals in the brew head

A tap to get the piston out

Piston is out to get cleaned

Cleaning the inside of the bore

Peter van der Weerd at work

O ring clip back in place

Old rubber seals off

Cleaning piston

New rubber seals on

Easing the piston back in

New gasket on neck of brew head

Ready to assemble

Old bolts had worn threads, new bolts look great

This is how to slip on the clips
The first La Pav 'sweated' a little around the bottom of the boiler. Inaudible and invisible, but holding a dentist mirror on a stick close to the spot did show some condensation.
Bolts on the other boiler were 'seizing' and therefore not closing tight enough, leaving the boiler to 'sweat' moisture

Greasing these bolts, now allowing a perfect fit for the boiler

Both machines ready to return home! Thanks Peter!

Stone slabs in the forest

In the little forest, cover small patches of soil with stone and let some be for twenty years, others fifty or even a hundred years and come back to read what they tell you about time passing.
