Plastered Dr. Grabow Viscount

[Dreadlock Holmes]

I recently attained this Rusticated Dr. Grabow Viscount, with a beeeeg chonk torn out of it. Originally I was intending to fill the offending section with briar dust and cyano acrylates.

Then I removed the mouthpiece. It was stuck at first and I thought someone had glued it in. THEN it finally twisted loose and I was met by a lot of white dust.

It seems someone tried to use Plaster of Paris to repair it once. It might have even filled the missing section. I want to know how to remove the plaster from the threads, and what the best thing to fill this gap with would be. Would would glue be better? It can be stronger than the wood it's attached to, BUT this isn't anywhere near the bowl or heat sources.

That Viscount has the Adjustomaic modified to use a stinger tenon instead of a hollow tenon with a 6mm filter.

Here’s your problem. Look how little briar there was on a really high condition Adjustomatic mortise.



Here’s a plan.

Try to measure how much shank you have left.

If it’s long enough, shorten the shank and try over again with your mortise, using glue. It needs to be slightly flush and the shank end must be perfectly cut to seal.

Then shorten the stinger as needed.

You still have threads in whatever material was used. The first thing I would try is to drizzle thin CA on / into the material to stabilize / strengthen it. Clean up the stinger and see how it fits. If that works you're home free - if not, no harm, no foul... If that doesn't work, you're really just back where you started and can turn to more destructive measures...

My initial thought was it’s aluminum oxidation. Or maybe someone didn’t know how the adjustomatic stem works and used that stuff to fix a misalignment.
Lightly scrape it off and use 000 steel wool to get it clean.

I've seen aluminum do that - but only in salt water...
