It's not a perfect. As you point out there are inherit problems, by design in some cases. Where in some designs (like the VL) the free play of the threads introduce an error. However that's not to say nothing can be learned by the exercise. One can still align/correct the assembly tolerances of the ...

You would need to show pics of both burrs (in their entirely) to infer results (use a light touch when testing). You're looking for an even wear amount in depth, size and location in the marking fluid/ink on both burrs. There are many ways things can be out of alignment, and often there can be multi...

Your final brew temp will depend on a few things, your HX flush routine and the machine/group you're using. HX flush routine: These have been discussed in detail here, so I...

I meant an ultrasonic cleaner. They work wonders for cleaning fine parts with tough grime. I use it for eye glasses, watch bracelets, my wife's rings and jewellery, misc parts, etc..
