I decided to make a quick block to test a radial micro channel design, to test manufacturing ability with my tools. That means cutting channels with a dremel. I didn’t have a new copper plate and was too lazy to go and buy new stock, so I used the base plate from an old soldered fins block.
To be able of holding steady the working piece and fine control positioning, I setup a mixed machine from my dremel, router attachment and my hobby multi machine. This way I can do precise 3 axis adjustments.
After about 3 hour work I had four channels cut to a depth of 4 mm on the 5mm plate.
A nice benefit of this setup was that the slow feed speeds and vibration free holding enabled a very high duration of the dremel wheel. I spent only one, a lot less than when handholding the tool.
Tomorrow I’m going to cut the diagonal channels, and want to finish it with a copper cap. Didn’t I say dirty?
