re: LUNCH THREAD - your best Uncle Rico high school story edition

Carbide bit, you'll have to keep the armature from turning without scratching or marring.

Vise grips would work, with a thick leather work glove. Glove inside the jaws of the vise grips.

Mild heat on the shaft, if possible, but may not be necessary.

What is the ID of the opening?

Leftover jambalaya and seafood gumbo...plus water.

Then tap an EZ out in.

It’s a pump. For some reason the shitty plastic screw is what holds the whole thing together.

If you can, see if it ( the screw) has standard threads and go back with a stainless screw.

Threads could be metric or SAE. The hardware store will have a wat to check it

But: be sure to put a thin coat of moly (anti-sieze) on the screw threads.
Stainless on stainless siezes like nobody's business.

Is the pump really old?

I have a spare screw I can look at. Pump is like months old. We use this instrument a lot and we go thru pumps.
