Expanding the lid's hole?

[.m.]

The air hole doesn't need to be very big to allow for good pour. The major factor is the spout. But spouts on shuipings have not been designed to maximize the pour speed, but rather for a nice shape of the pour stream.

I've opened up most of my pots with the diamond tip bits, just do it by hand on the lid... Takes a while but I've taken off 3-4 seconds pour on most. Even on filter holes. Just takes time and slow work.
I do use the dremmel with a round tip bit for the spouts.... Just practice with a throwaway pot for a while first...
If your not super steady hand... Then don't try it...
The regular files didn't work for me.

Seriously? you mean in order to enlarge the opening? What kind of tool are you using for this? I guess it is supposed to be something more sensitive

A Dremel w/ a round bit. A precision handheld power tool that basically has a million uses for craft/hobbiest.

I assume with a bit like this.

Pretty brave--I won't be trying that!

Like this one, https://www.amazon.com/gp/aw/d/B00004UD ... iamond+bit

I'll try to do by hand if possible, but some need the power to get through a thick walled, almost closed spout..

Yep I practiced a bit first on a $10 pot...
But I'll say it has made a big difference in a pot that was like 12-15 seconds pour.. Down to 7-8 seconds..

Orchid teahouse gave me the idea and initiative to try it...
The one for the lid hole I will only do by hand with the point diamonds bit.

Won't touch an expensive pot though....

What pots have you done this on?

Late 80's F1 seems like reasonable cut off or green label if it's not in not in perfect condition.

[Emmett]

A modern non factory , and a couple early 80s f1, as those are the ones which are most affected in what I've had. A little more sloppy workmanship on some. Seems shuiping is more affected.
Seems like white sticker are made a little better inside the spout.

Some 70s just the lid hole, and the filter holes. On 14 hole. These by hand only.

btw here is the actual file i use



the others in the set don't seem to be helpful for teapots
