This thread was really helpful! Thanks guys. I thought I broke my freezer line, but I tried it today and it got way to cold. I drilled my hole in the plastic casing and gave the coarse screw two twists. Now I'm sitting at 40 F! Next step is drilling my hole. My plunger shaft is just under 7/8...
I'm looking for Centennial, Cascade, Fuggle, and Willamette. If you know of someone or have a recommendation of a company that I should check out please let me know!
