I have an old metal body Gaggia MDF grinder. The motor shorted out and I took the grinder apart. The insulation around the wires had disintegrated. I tried to pull the wires but they were incased in the copper wrapping. Is there anyway to replace the stator for this motor? When taking it apart I really appreciated how well this thing is made. All metal, gorgeous italian engineering. I can't make myself trash it. Any suggestions?

Sorry for not getting back to you, I'm still deciding whether I'm going to keep it or not. I've done some grinding on the housing and made it doserless. It seems to have a static problem now though.

Here's the story...The grinder works but the doser plastic was broken and I couldn't find another one that fit. I did find parts eventually but they were for a later model MDF and weren't going to work even with modification. This model is probably 12-15 years old.
So, I hacked up the body of the thing thinking what the heck, lets see if I can make it doserless (inspired from another MDF doserless mod). I'am sort of regretting doing this now but the deed is done. I was thinking at the time I was going to buy another grinder anyway. Maybe I should have looked harder for parts...
Yesterday my wife comes home with a Bodum Bistro...and the mother in law is not happy I hacked up the MDF. I guess I got a new grinder. So, I'm sure where I stand at this point. Didn't really want the Bodum...

I believe the old MDF grinders used an induction motor and direct drive while the current machines have a brush motor and gear drive. I'm guessing that Gagga won't have the stator, but it won't hurt to check. You can also get a motor rebuilder to rewind your old part, but I'm guessing it will be spendy.

I don't know if there is enough left of your MDF for this to be useful: "I civilized my Rocky"
I'm not fond of dosers for home use myself, especially crappy ones like in the Rocky, but they do help with static
My current technique is to place the basket on a dental vibrator while stirring the grounds with a small wire whisk. Then I put the basket into the handle and tamp on the vibrator with it running full blast. I still get the occasional squirty but over all it's pretty good.
By the way, the canning funnel should be electrically conductive to help with static.
