Body Facing Tool. This tool is not currently set up as we are past this phase in the current run, but here's a photo of the components. When we rough cut the bodies, we then need to put an accurate face on them with a 1mm lip. When this tool is set up in a vertical milling machine, it holds the body while the custom cutter faces it and leaves that 1mm lip.
The bodies then get an internal relief, but that requires no special tooling. We just use a lathe and boring bit.
Body Chamfer Tool. After facing, this tool puts a chamfer on the body before threading. This aids to get the taps started straight, and reduces wear on the taps.
Left Hand Threader. After facing and chamferring, we use this giant tapco with bottom bracket tap, and this fixture to cut the left hand threads into the body.
Indicator Marker. After left hand threads are cut, the body moves to this fixture to get its small hole drilled to indicate the 'left hand threaded' side of the body.
Right Hand Threader. After marking it, the right hand threads are cut by another tool using another giant tapco and custom fixture.
This is the tooling we use to cut excess weight off of the bodies when we are making the light weight version of the eccentric. It is currently not being used as we are making Retros right now.
Wing Facing Tool. Once the wings are rough cut on the saw, we use this fixture to face them to 66mm and give them a nice finish. The tool is calibrated to cut them to 67mm on the first pass, then in the other side they get cut to 66mm. A big time saver for us. One set up produces 2 wings per operation.
Wing Ramping Tool. After facing, we put the ramp into the wings. This fixture does 2 wings at once. So each pull of the lever produces a finished part. If we are making Retro models, then the wings are ready for grooving at this point.
Light Weight Wing Hogging Tool. This tool is not completely set up in this picture. In addition to the fixture that holds the wing for cutting, there is a bit that would be in the mill head to cut (or hog) the material out of the wing. We are currently finishing a run of Retros though, so no hogging is taking place.
The last thing we do before tumbling the parts is to put a groove into the bodies and the wings for the spring to fit into. This is the custom tooling we use to do that. As you can see by the chips, we are currently running parts.
