Anyone here do it?
Prices for 1#ers are CRAZY!

been doing it for the past few years but often can't get a tank to fill up.
Sometimes, bout all I can get is 1/2 tank.
Any tricks to use?

Empty 1 #ers in freezer for an hour or two
before refilling, while 20 #er in full sun.

Just getting ready to do it after lunch.

The ones that don’t fill I throw away.

You don't need to freeze them. Use a plastic or wooden punch and purge the air from them through the valve. It will take 2 to 3 times before its full. Once the bottle weights 1.9 lbs it should be full. I've been doing this method for years and it works great.

Here is a youtube video of a guy using the same method that I do.

I use my wife's electronic scale to weigh the empty and then add just short of 1 lb. It won't fill all in one shot. Chill the 1lb in the freezer for a few minutes. It doesn't take long because it's only the metal tank being chilled. Once the metal reaches freezer temp it won't get any colder by being in for an hour or two. Connect to the 20 and put as much in as will go. Put partially filled 1 lb in the freezer again for about 10 min to chill the tank and propane. Fill again and check. Lots more will go in this time because of the chilled propane in the tank. Repeat as needed to hit your target. 2 or 3 shots total should do it.

I freeze mine, for days (just cuz I throw them in when they get empty), and fill in one shot. If I wait till I can't hear anymore going in, I have let them "vent" outside when they heat back up.

For those that do, do you have trouble with them on a soldering torch? Mine seems like they get vapor locked or something, until the fuel is purged for a bit.

I use refillable tanks made for doing this from menards, I bought the kit and it work easy!

I have the stuff to do this also. I guess I'm a bit confused on why everyone is using a freezer. Liquid propane is -88 degrees.

I position the safety bleeder on the 1 pounds up when filling them, then use 90 degree needle nose pliers to pull out the safety until LP comes out, then they are full.

You need to depress the vent on the small tank to relieve all pressure, then freeze as has been suggested. I once overfilled a one pound tank and had to place it outside in the sun to sell vent. Do not obsess with packing that last ounce of propane inthe tank. It may vent right back out and pose a safety problem.

Yep, I do same, but fill to weight on a scale. If they are overfilled, a hot garage in summer could be a bomb.

Interesting methods guys.

Gonna try some tomorrow.
Thanks.

Which reminds me, I have about 30 bottles to fill

It cools the receiver tank to create a pressure change, which creates a vacuum.

Cold 1 lb bottle and warm 20 lb tank. No need to screw around and purge when you have a substantial temperature difference. It's a minute job if you're slow.

That’s exactly how I fill mine.
