emradguy, if you want an expert viewpoint about using a refractometer in coffee, consider making a very small investment ($10) and buy Scott Rao's ebook "Espresso Extraction." It goes into considerable detail about the topic we're discussing here.

Thanks Andy!  I am definitely in need of some books, so I'll put that on my list as well.

Regarding your schnozzola.  I don't know if you've seen my Major mod thread on here...but included in it, I'm working on making my schnoz out of brass.  I have it cut to your specs, using your template, and am now deciding on the best method of uniting the ends to "complete the ring".  I was thinking I'd offer to send you one, assuming it all works out well...and, of course, only if you're interested in that. Just let me know at your convenience.

Thanks for the offer, that would be great.

If it were me, I'd solder it together. It would require some appropriate flux and a little lead-free solder. If that's a little more than you want to get into, perhaps the Gorilla Glue will work fine. I'd be sure to roughen the joining surfaces with a little fine sandpaper before gluing

lead free solder...great idea! You know that saying, "measure twice, cut once"? Well, I didn't follow it. I glued the Schnoz template to the brass, cut it out with scissors, then removed the template with acetone, then washed any residue off with mild soap. Then I soldered the thing into a nice cone. It worked great...then I ground down the excess solder and polished it with my Dremel to make it look pretty...then I found out it didn't fit in the grinder! I guess it was good practice, huh? So, at least I know it works nicely.  Andy, if you pm me a mailing address, I'll send one out to you as soon as I can get some more free time...don't worry, I'll make sure it fits in my Major first :)

OP, sorry about hijacking your thread!!!! It definitely wasn't intentional.

As the expression goes, "Experience is a comb nature gives you after you're already bald."  :-)
