Metal Grinder
29th Sep 2017, 07:29 AM
Hallo everyone...first post. :)
I am in the middle of restoring this old Danish coffee grinder from 1962, called Caravel de Luxe. Some parts are at the Paint Shop getting a fresh coat of candy apple red, and I am re-winding the 0,5 horsepower motor myself.
It is getting the big overhaul, but I am stuck with getting the burrs/knives re-grinded and re-sharpend.
It is a bit tricky because of the conical shaped burrs in front where the grinds come out. I tried to ask a few companies, but so far none of them had the tools or machines to do the work...or maybe they just didn't want to deal with this type of job?
I have been looking at quite a few videos about grinding and sharpening drill bits, and also OD + ID, so there must be companies somewhere who are able to do this type of work.
Or if there would be a private metalworker out there, who has the skill and tools, I would be very interested hearing from you.
I am living in Denmark, but have a friend from the States, who can help with the logistic part of it.
The whole project is also shown on this coffee forum, plus a few videos: https://www.home-barista.com/repairs/restoration-of-caravel-de-luxe-t47206.html
This first picture is the meassures of the three inner burrs, so you get an idea of the size.

This is how the final edge have to look like. This is a set of normal looking conical espresso burrs.

And the rest, is of the burrs of the Caravel grinder that I am restoring, and need to have the same looking Final Edge as the picture above.
