So, too many years ago I bought a set of pipe cutter wheels with the intention of making an oil filter cutter. At the time, they were still a little on the pricey side. So, every time I looked in my junk drawer they were staring me in the face. Time for action lol.
I made the body from 30mm square tube (steel).
The sliding part was made from some unidentified Australian hardwood that came from a pallet. I sized it to fit inside the tube. I drilled and tapped it to hold the bolt that holds the cutter wheel. Interesting note, after cutting the threads I drenched them with super glue and let it dry before putting the bolt in, which firmed up the fit of the bolt quite well. A piece of all thread bar pushes against the back side of the hardwood bloc. I used a nut with some washers welded on two sides to act as spacers, then drilled and tapped to use the two round head screws to secure it to the main body.
I initially had three cutter wheels, but early testing showed that one would cut through the filter housing in one spot first, and then the cutting would stop because I couldn’t turn the cutter any more.
So, hop onto eBay and order a pack of roller blade bearings and wait.
After this the cutter works great.
So, back to the costof buying one pre made; they can be found on Amazon for as little as $17 dollars! So I am true to Garage
Journal tradition 
.
Once it was operational I cut open some old filters, and I was surprised at the carbon and grit that was inside from my relatively new cars. No metal chips though which is good news.
