Expanding the lid's hole?

[ShuShu]

I have two shuipings that are exactly the same except that one pours almost 5 seconds faster. The difference between them is in the hole on the lid. The air on the one with the fast pour runs much faster and it is slightly bigger. I have been thinking about trying to expand the hole on the one that purs slower a little bit using something like this (1mm Diamond Grinding Burr Drill Bit).
Have anyone here tried something like this? does it make sense?

I have heard of members here and previously at TC using diamond tip drill bits on irregular filters, very carefully and gingerly. A simple search like this https://www.teachat.com/viewtopic.php?f ... ll#p210394

In that thread one message commented on the difficulty finding a file small enough for some holes. Diamond wire coping saws are available in various thicknesses, and might work well for this application.

Possible but risky. i'd probably file it by hand, rather than using dremel.

(btw. i suppose you tried swapping the lids to test that the obstacle lies indeed in the lid. )

fyi



(i hope it's ok to post here somebody else's post)

Of course, only by hand... and yes I got to this conclusion by swapping the lids

I would also discourage power tools.
I've successfully cleaned up and enlarged a lid hole using jeweler's needle files (the needle/conical shaped one is best). Working very slowly and gently. If it binds up, never force it. Gently work it free and continue with less pressure.


edit: those look kind of rough. here is a picture of the actual ones i have:




they're diamond needle files from harbor freight.

Thank you very much.
Though those in the pic look quite large. These are the ones you used? I’m trying to find something less than 1mm

The A & silver set comes with .8mm

Not sure why you'd need something smaller. I just measured my pots and all of them could handle larger bits. Start from underside of lid if hole is tapered.

I've used those type of files for lid holes. My suggestion is to have bowl of water handy, soak the lid and always keep the hole wet while filing. I go in a gentle circular motion (spinning the file back and forth between fingers.) Also go from inside to outside, that way if you chip the edge of the hole (where the wider part of the file touches) it will be on the inside and not the outside. Don't file any more than you need to for a good pour!

Success!
I only used my hands (no power tools) and it took an hour or so, but now it pours like a champ - from 13 sec to 10 sec. not bad for 120ml shuiping

I wonder whether it can get even better if I keep going...

Just do enough to get the hole clear and the size it was meant to be. Risk of damage increases the more you mess with it! But, of course, do whatever you want
