Mazzer Major Reburb and Doserless Conversion - Some Tips and Questions - Page 2

Thanks again to both of you.

I've now done the following:

- take the bottom doser wire and cut it before the solder points
- reconnected the wires that it was soldered into
- removed the top doser wire entirely
- run a very short wire to jump the connectors on the relay where the top doser wire was run initially

Since my grinder is still completely disassembled (painting process is not complete) I haven't turned it on yet, but I feel fairly confident that I've got it right now. (But please do say so if I'm missing something!).

Oh, and John, I appreciate your reminder about making certain the grinder was not plugged in. I almost always double check, but it's the sort of thing where triple-checking is a good idea!

If you cut your funnel down to about 1" above the mounting screws you will find it much easier to sweep out the chute. How is the static/clumping with the plastic funnel?

Good suggestion about the height of the funnel. It's at the height it currently is simply because that's where I cut the 2 L bottle off. But you're right, the angle makes it hard to get to the chute.

I've only had this operational for 24 hours, but at the moment I'm getting no static at all. There's probably a small amount of clumping, but not very much. And certainly not that I'd notice, coming from the Saeco Titan, the Mazzer just makes the fluffiest grounds I've ever seen...!

Nice restoration and nice colour. Though if it was over here in England, you might have people trying to post letters through those slots :shock:

You're right: it does look like a postbox!

I lived for the last 3 years in Wales before returning to the States...

Any way you could post a video of it in action?

That looks so nice. I'm almost tempted to have a go at painting the one I just bought although I kind of like the tatty gold Donald Trump bathroom colour on mine. Can I ask what you are using in the throat instead of the hopper? I have been using a 53mm tamper I had lying around in the SJ but in the Major it touches the spinning hex bolt if it's not sitting straight.

Scott - let me try to dig out the old video camera and see what I can produce.

Sam - First, the painting project wasn't all that hard, just time-consuming. The better you do the prep work, the better it comes out. I was in a rush and only 2 coats of paint (after 2 of primer), and I think I'd do 4 thin coats if I was to do it again. And you need to have a good ventilated place outdoors to do the painting, which in my case wasn't easy to find.

As for the throat: I, too, started by putting the tamp in there, but that looked like a bad idea long term to me (hex bolt). Right now I have the bottom collar of the standard hopper; it disconnects from the hopper with just one screw. I just open the little trap door to put in the beans, then close when I grind. This works fairly well except: A) it won't hold many beans this way, and B) the opening into that collar is very small, so it's easy to spill beans.

I think some folks have fashioned little PVC funnel setups, and I'd love to hear recommendations or see links to those solutions. I don't have much space to clear the cabinets, but I'd love something a little wider and a little larger.

Here are photos of stainless steel canning funnels. A very sanitary mod! Here
