I have not read all the back and forth claims, accusations, and insulting comments relative to the claim by Paul Shinn etal stating that the crank and cam shaft engine kit parts he received from Terry Burtz etal are out of spec. I am an engineer with many years of automation and manufacturing engineering experience. It appears Tery Burtz's Chinesse engine foundry and component machining resource is producing the Burtz engine with modern methods of manufacturing and quality control. The entire Burtz engine design has been developed using Solid Works design system. Solid Works is widely used domestically and internationally and is the accepted engineering design software used by many US manufacturers. This design system not only is used for the product design but can also be applied to product manufacture.
In my view the professional way of handling any type customer-supplier product quality related dispute is to have both parties share their disputed claims by each formally documenting their respective supporting data. It appears Terry Burtz's supplier uses cnc controlled machining methods with components mounted in precision fixtures. Their component inspection methods for quality control is performed in a seperate controlled area. They also use coordinate measurement machines (CMM) which are very accurate, repeatable, and well established automated gauging systems. The cycle or frquency of inspections appear to be made based on statistical performance/confidence data.
I recommend Paul Shinn etal andTery Burtz etal each prepare a written document indicating what the disputed quality issues are, show how these items are or were inspected, mutually share this information, and meet to make recommendations for resolution.
Once this excersize has been completed they can then share the results with this forum.
Jack and many others,
Thank you for your comments
Paul Shinn has never published a list of dimensions from Willie that he thinks are out-of-tolerance. In Pauls's retracted video, he stated several measurements that he believes to be out-of-tolerance. The most notable out-of-tolerance dimensions can be found in post #1 of this thread. One of Paul's assertions in his deleted video was that his 2 "New Engine Kits" could be combined with $4800 of machine work to make one new engine.
Post #1 in this thread also describes how the "New Engine" cylinder blocks (and other parts) are verified at the factory using a CMM in a dedicated temperature-controlled room.
Those that are familiar with SolidWorks and automated machining know that if you have a discrepant part, there is a likelihood that all parts in the same production run will have the same problem.
We never doubted that Paul Shins's parts had a problem, but needed to know because the problem may have resulted in a costly recall.
After 2 months of prodding, Paul Shinn agreed to take his parts to a 3rd party for evaluation.
Paul chose Tim McMaster at Hanford Auto Parts to be the 3rd party and evaluate his new engine parts.
Paul spent an entire day at Hanford Auto Parts taking videos and condensed those videos into one that is just over an hour in length.
The measurements taken by Tim McMaster at Hanford Auto Parts and recorded by Paul Shinn are in Paul's video that he won't publish. We have the measurements in a separate document from Tim McMaster, and they are published in post #28 of this thread.
We cannot post Paul's deleted video with Willie and his video taken at Hanford Auto Parts for legal reasons.
If Paul wants to present himself as an unbiased reporter, he needs to let everyone see his complete video that was deleted where Willie states that for $4800, he can combine Paul's 2 "New Engine Kits" to make one new engine, and the entire condensed video taken at Hanford Auto Parts where Tim McMaster made measurements that Paul recorded and where Tim stated that there are no problems with the 2 "New Engine Kits" that Paul brought for evaluation.
Our sales are to individuals and engine builders. Paul was denied being a distributor because we don't need middlemen that will increase the price for consumers. This may be a factor in Paul's reporting.
Paul either needs to "man up" and say he made a mistake, or continue with his assertations that the "New Model A Engine" has many problems.
