10# PotSlow trickle

Postby cj8281 » 02 Jun 2020 21

Hi all, I have a tall 10# pot that has always leaked. Last Sunday I warmed it up and dumped it out. The handle would actuate the valve rod but it would not flow. It was hot (set on 8) but the tip never cleared. I tried to drill out the tip after it cooled down. Had to remove the bottom to drill from the tip up and then had to extend the drill bit almost to the end of the shank to be able to drill the pot side. The tip looks like it was a cross drilled design. I could see day light through it so I then cleaned the tip of the valve and then used some lapping compound to lap the valve into the seat. Kept the valve at the same angle as it would sit during use. Cleaned it up and then reassembled and filled the pot. I then tried to cast some 38s. About half the time it would not fill the mold. The stream is really small and the flow is really weak.

Have I screwed this pot up? The drill that I used to try and drill the crud out was a 3/32. Should I try a bigger drill bit?

I did try and add to the other post about the 10# pot but it would not let me so I started this post.

I have the same trouble. Mine has never worked right and I bought it new. Tried all the fixes listed here and elsewhere. It either leaks badly or doesn't flow at all.

Good luck.

All I have ever used to clean the tip is a bent paper clip. With the pot hot, full and valve closed I just root out the tip. I operate the valve a few times with the clip still rooting and I get full flow back everytime. Get a few drips occasionally but using a screwdriver to twist the valve stem a couple of times stops that. If mine plugged up I would start with an empty pot, valve stem removed, use a propane torch to heat the tip and apply air to the tip with a nozzle that has a good seal. A good cover for the top of the pot would keep any hot bits that blow out of the tip in the pot. You could blow through from the pot side but my experience with any plugged passage is it is better to blow back against the normal direction of flow if this is possible.

I cleaned and lapped a few times but still suffered from drips and a poor flow. (sounds like a prostate problem... :lol: )

I finally plugged the pour hole permanently and bought a Lyman lead dipper.

No drips and now I get much better fill out - especially on the big molds.

@ klr, I have actually thought about that but I am getting one of those big 00 buck molds and I want to be able to pour it one shot. I don't think it will fit under my short pot.

I will try the propane and air trick next. When I have the valve out I plugged it in and it never opened up, even with a paper clip. Spout was solid, both directions.

Well I've tried all that but Lee cross-threaded several screws putting it together so I cannot remove the valve.
