Rosineer Stainless Steel Cylinder Pre-Press Form, 30 mm

Rosineer Square Pre-Press Form.Top Quality & works as intended. It is a stock extruded Aluminum tube with machined Alundum end caps.Use it with a soft hand clamp or small rubber hammer & tap Lightly.(Do use a hydraulic press or a steel hammer). It comes with instructions.I have read the bad review & are all B.S. from mishandling or wasn't pretty enough.For you first timers, put down pipe and follow instructions. All good.Cheers.

I use it to press my used sole crumbles into new bars, saves me soap and money!

Presses my bud just how I want it.

Heavy duty and works exactly as needed!I love it made of stainless steel Instead of machine aluminum and has a little more tensile strength to handle the pressure of pressing

Works very well, quality built, huge capacity, easy to use

The mold quality is extremely high BUT the actual interior of the press in NOT 1.5"x1.5". It's closer to 1.25"x1.25". Measuring from the exterior end to end is 1.5"x1.5".

Very high quality pre-press, it increased my yields 5%-10% over not using a Pre-press prior to having this one. And makes the entire process of getting your materials ready to press a lot faster.

First off, I am not using it for its intended purpose. I wish the price was lower so more can be purchased for my class lessons.I purchased this to use in my Science class to help my students visualize specific concepts:* Density: Using aluminum foil to start the lesson, students would ball up the given foil and measure its density = mass/volume. They would then crush the foil down, remeasure density; each time, the mass remains roughly the same. When small enough, students place their ball of aluminum foil into the press and using a hand held ($5) clamp to crush the foil. In the end the students see how "dense" their new object is. They remeasure and find the mass is still roughly the same, but the volume is greatly reduced resulting in a much denser object.* Rocks and minerals: Pressure is a key and this device lets my students actually create their own form of sedimentary rocks. Metamorphic rocks are heated with teacher assistance. Students get a hands on experience and better grasp of the concepts, including the "layers" found in rocks, mountain formations.

It broke on the first try. There are no instructions with the item and no information on the product description as to how many psi or pounds of force it can take.I made one small brick of hash and then notice that the walls of the mold had warped which made it impossible to remove the inserts so therefore had to get a flat head screwdriver in a hammer to force it out.As with others that have indicated the same problem it would be nice to know how much force is to be applied how much material can be put into it. Honestly I think it's just a very cheap metal and too thin.
