First, Apologies to anyone out there who actually does this for a living but I stumbled onto a process for electrochemical deburring of the fuel pickup tube.
My little band saw leaves horrible burrs inside and out on the slots for the tube. As you can see on this scrap tube:
I know how the electrochemical process works theoretically but I have no real knowledge of the details, so this is what I did.
I filled up a glass measuring cup with undiluted alumiprep and placed a scrap piece of tubing into the solution to use as the cathode (Negative polarity) and the piece I wanted to deburr was conected to the positive post of my battery to become the anode. I tried a 12v battery first but, for my solution, it was too little so I connected my Dewalt 18v power pack in series for about 30vdc total. The 'mad scientist' arrangement is here:
After leaving the tube in the solution for about 15 minutes, this is what happened:
The burrs were totally removed and the surface of the tube was partially polished.
Yippee!!!
