I picked up one of these badged as a Nuova Simoneli very cheap. Appears to be newer and has new burrs.

I've been searching for the parts on the 80 step mod, but can't locate them. Does anyone know where to find them?

Rossi is out of business so you will find the ring where you find it. You may try places that sell machine parts, we have several that advertise here, that would be where I would start.

Yeah - the RR45A collars are difficult to find.

However - you might also get a few tubes of superglue gel and use them to fill the spaces on your current collar. Once they are filled and dried, use some emery cloth to smooth out the surface and you'll have a stepless grinder.

I am a bit of a moron when it comes to modifying things so wanted to avoid messing with it and ruining the poor grinder.

I think you can remove the detent pin without much difficulty, which would also give you a stepless grinder.

You can do that, but then there's nothing stopping the grinder from slowly turning it's adjustment collar while you grind and we don't want that.  You can mod these to stepless, but you need to add a system to lock the collar in place, which is the job the pin does in stock configuration.  There have been a number of posts here and on HB detailing the process.  Once modded stepless, they are quite a good grinder (sort of between the mazzer mini and SJ in grind quality)
