V8 KnockOff

This project entails engraving a logo onto the knock offs prior to chrome plating to put the finishing touch on an awesome custom hot rod.

The plan is to ball mill the vintage Ford V8 logo on the center. To ensure an accurate engraving the convex surface needs to be modeled correctly.

The easiest way to hold them with out damage is by the threads.

To prevent damage, hold concentricity and location we used custom soft jaws on a 3 jaw lathe chuck.

It’s important to clock the rotation prior to machining for appearance consistency.

We made several adjustments until we got the right width and depth for the paint inlay.

The line widths are consistent; looks like we modeled the convex surface spot on!

Another challenging project executed perfectly.

Sucker Rod Tong Casting 1

One part of a complex reverse engineering project.

A lot of as cast and machined surfaces to duplicate with a multitude of features all requiring accurately defined relationships to produce a good part.

There are a couple of 3D models to make; one for casting and one for machining.

The first step is to create the as machined model from the data gathered. It is important to identify the parting line and establish it as a datum to control the draft in opposing directions.

Creating an additional 3D Model for the casting pattern allows it to be CNC machined. Minor edits from the as machined model are required to add material in the areas to be machined; casting shrinkage can easily adjusted with a simple click of the mouse. The increased accuracy results in virtually no reworking of the pattern and no dimensional discrepancies in the castings.

Once the model is finished, shop drawings are produced and checked against the original part to validate the model. The shop drawings, once the model is validated, are used to machine the finished castings.
