[ERA Chas]

Bruce,
Thank you for the extensive reply to my comments. It makes for a compelling ad for your business.
Like Rick and you, I too "get it". I have been steadily improving my ERA, in both materials and techniques for a long period of time. I, too have a professional shop and complete equipment, and my enjoyment is much like yours.
My concern and the focus of my comment was essentially, satisfactory equipment or alternatives already exist from ERA, and your customer would be safe and dollars ahead without the need for you to re-engineer a system.
However, you go on to explain that you perform this service at your own expense of time and resource and you receive great satisfaction creating a new solution.
After your explanation, I now completely understand and fully agree.
The distinction is that Rick and I modify and improve our own cars, [it's "what we do"] and you perform a service for others.
Get it?
