Custom Tool, Inc.

This is one side of a set of custom brake shoes for an old Triumph. Owner had them drawn in CAD and I cut both sides and put in some other holes so he could put brakes on his old car.

One of my current mold projects. These are pics of the inside core of the part to be molded. Also shown is the current part I'm replacing because the mold is worn out. This core started as an 85lb block of P-20 steel and is first machined with a 6" x 7" square register to fit into the mold base and all the ejector pins and water lines drill from the back to cool the block during molding and the ejector pins to push the part off the tool after it's molded. The core is the positioned against that back surface and located perfectly to machine each side and then rotate to the next side. In machining a major part is determining the sequence of how to "hold" the block in way that you can accurately machine the features all the to completion. You can see the features on the block that are opposite of the inside shot of the white part. I know it's hard to turn your sight inside out to visualize this.

These are billet aluminum jetski rear nozzles I am making a small number of for a colleague in various stages of completion. Photo on the left is the 6 x 6 x 7 block that I start with and machine the inside features and a bolt pattern on the fl**ge to rotate it 180 degrees and attach it to a fixture. They also serve to attach it to the pump on the jetski.
