You don't have to need something as cool as a custom gasket cutter.

Olfa cutter : #90B Heavy-Duty Compass Circle CutterOriginally posted by JMcCee View PostWhat's a gasket cutter from Japan look like and why do u need it?
Because I didn't know how else to cut a perfect circle in Klingersil 4430 ... not even sure this will do the trick ... but I hope so.

Things starting to get a bit more serious now ... re-assembly commenced ... but still waiting for tools and parts to be able to make real progress.
Interesting to look back at where I started (see fourth photo in this post).
If anyone can point me in the direction of some rubber seals (see picture for example) for the boiler level sight glass (9mm ID) I"d be grateful. The seals were toast and I doubt the dodgy o-ring configuration I came up with will seal. From what I can gather the CMA/Astoria set up is for 11mm glass tube so unfortunately the commonly available gaskets are no good.

Thanks ... I'll 'pack' the space with a washer ... but I doubt the piston will turn on the shaft anyway with the big spring holding it firmly in place.Originally posted by kofekitt View PostBottom of piston should be approx flush with bottom of bore, have a pic?
I've already installed the shower screens, and at $20 a pop I don't want to risk damaging it trying to remove ... so no ability to check how flush with bottom of bore unfortunately. Might have to cross my fingers on that one.
I should have studied it more closely, but when the bore is up (ie. spring compressed) fully, I assume it is above the water inlet point to the chamber. But what are the small holes in the base of the piston for? Are they just to slow the pace of water pushing against the seals when the piston is released? Or do they have some function associated with the inlet?

The holes in the piston are to allow water flow through and too 'energise' the seals (make the seal edge flare out and work better)
Are the shower screens the toothed variety? If you push in the middle (with the piston raised), they pop into a concave shape and are easy to remove. Same for installing - pop them into concave shape, hold in position, and poke a wooden dowel down the bore to pop back into convex shape

Cut a boiler gasket using the new gasket cutter which worked well. Waiting for stainless fasteners, but put it together with mild steel bolts as a test run ... lookin' good!
Any reason not to mount the new pressurestat directly to the boiler? Previously it was mounted to the frame via copper pipe with compression fittings etc ... but I selected a pressurestat with the right sized fitting so fitting directly to the boiler was an option. I can also make up a pipe to mount it away from the boiler if there is a reason to do so.
