What's The Deal With This Mastro de Paja Stem?

Post by Goose55 » Wed Sep 06, 2017 6:56 pm

I refurbed a Mastro de Paja lately, and the stem is the oddest thing I have yet seen. Anyone here know what all this is about in the tenon? This has got to be one of the most difficult stems to keep clean with all that?

What's it's purpose? :confused:

Elaborate, o Bob of Specialized Knowledge. I have many like that. I always assumed it was for some condenser doohickey. Why would they repair it like that?

Well it looks like shoddy work. The pipemakers here will be better suited to give a more complete answer but it looks like the stummel was drilled a replaced. I sold a bunch of new Mastro pipes and I never saw any new ones from the factory like that so it looks like it was a poor repair job to me.

I see. I'm not arguing, just suddenly curious. Why the channel? Looks like it would accept some form of gasket.

The channel is a sign of poor mending. I suspect the repair person drilled out the broken remains leaving the channel. They could have matched the diameter better. But FredS would know better.

A pipe that takes an O-ring. Thiokol or TWSBI.

I can't imagine why anyone would do that unless the end of the tenon actually is seated in the base of the mortise.

Well, today I learned something, Thanks, guys. I have at least four or five old pipes that look like that. Maybe a home job? Couldn't imagine paying for that.

And Goose, it's not as bad as you think. It won't gunk up exponentially. I speak from experience on that one.

They used to sell the tenons pre-fab and often with a differently sized air hole than the stem. You just drilled them out and glued a new one in. Jobey fixed this by making the tenons pre sized so you just unscrewed the broken one and screwed in a new one.

Older pipes (GBD comes immediately to mind) seemed to often have something similar to Goose's example (i.e. a stepped-down tenon). There must've been some logic behind that. I'd always assumed that the supposition was that the step-down would discourage moisture collecting on the mortise walls from wicking into the draught-hole. Rusty would prolly know the real story, though.

It looks like the stepped down piece is a spacer for filter pipes for those that don't want to use a filter to me but Ser Jacopo doesn't make filter pipes do they? I've seen some factory pipes with the stepped down tenon. I always assumed it was an attempt to prevent moisture from getting in the stem and consequently in the smokers mouth kind of like a stinger. The tool marks on the face of the stem are suspicious. It's very possible that UB is right that it's a poor attempt at a tenon repair. It's possible the repair person refaced the stem but did a poor job of it. I've never heard of such tool marks on stem faces of new Ser Jacopo pipes.

It's a mystery, Scooby.

I have a basket pipe with that sort of step (without the groove) on the end of the tenon. No idea what it's for. Like hugodrax, I left mine alone and it's pretty much gunked up the void space. I don't s'pect goose will do that.

I have two Mastro de Paja pipes. The stems on both are magic. Best parts of the pipes.
