Leaf compression for 1-inch thick plug?

[piping_presbyter]

In your experience, if the goal is to make a 1” thick pressed plug, approximately how tall will the unpressed stack of leaves be? Assuming they were relatively flat (no folds) and figuring 35psi for 1 week will be applied.

Basically, I’m wondering how tall my press needs to be since I’m constructing one this week.

Thanks!

I've never been able to predict that. I would make the mold at least 3 times the final plug height you hope for. Then fill and compress for an hour, and add more if needed.

Thanks. On your recommendation, plus a dash of conservatism, I’m building it 12” tall. I’ll post the build and results when done.

So, that’s my second plug made with my box press design. Here are some build videos I made:

Great press solution... simple, elegant. Did you find that you need an additional amount of casing to get the plug to stick together?

I like the looks of your form, Im looking to make one myself this year, thanks for sharing! What kind of woods are recommended? I figure none of the more aromatic woods, but I only have experience with cedar and pine.

I use white oak. It is cheap, strong, and available.

Neat!

I suggest weighing your favorite plug and then dividing the weight by the area of one of the pressed sides to get the mass of tobacco per square inch of your press face.

I did this for a few GLP plugs and got about 15g of tobacco per square inch of press face. So, having made one of your wonderful presses, I have a press face that is 2" x 3.5" (7 square inches). At 15g per press area that's 7 sq.in. X 15g for a total of 105g of tobacco.

This gets me a plug that is about a 0.75-1.0 inch, but it varies with thickness and moisture level of the leaf.

Welcome to the forum, @kellyhh. Feel free to introduce yourself in our Introduce Yourself forum.

Your computational approach is clever. For a 2"x 3.5" plug that finishes to ¾-1" thick, just use ¼-pound of tobacco. While I believe no great precision is needed for pressing a plug, the moisture content of the tobacco added to the press mold could introduce a significant variation, when measured by weight.

Thanks, Bob. 105g works out to about 0.23 pounds, so we seem to be getting similar values. I express mine in grams since I tend to measure out component tobaccos in grams. But each to their own, certainly.
