Just some advice for anyone growing their own organic rosin. After spending a fortune on several other pressing machines I found something sturdy that really works for me and has completely replaceable parts in case of any wear and tear problems. It’s a “Dabpress” from Amazon and for $430 its worth every penny. I had even built my own press from a H-frame shop press from harbor freight and ordered heat plates with a PID control unit… Took it all back. That way sucked in a lot of ways, and only $50 cheaper than a professional DIY “Dabpress”. Save yourself a true headache and just spend once on a safer product.
