As I said it is your choice to do what ever you wish to your tools, not going to get into this any further, end of conversation with me.
Obviously, we can all do what we want with our own tools, that's a given. What makes us a better woodworker may require a "modification" to an existing tool or machine because it improves accuracy, safety or efficiency. That's mostly what I like to do and "My Photos" is filled with machines I have either built or modified to suit my needs.
I have received countless approving comments on my Craftsman triple 12" table saw over the years and have had several members duplicate it with 2 saws, Ledhead for example. He came to visit, saw my setup and went back home and built his own from two 10" Rigid saws mounted side by side.
Necessity is the Mother of Invention, so improvements that make a safer or more efficient machine are a good thing. Modifying or eliminating safety devices are probably a "bad" thing, but I'll admit to having done so. The designers or engineers of a product are only human, and they are not always right. I know this because, not only am I an Industrial Designer MFA with 35 years experience, but I've worked with some of the best in the business. Some designs make it to production but are certainly flawed and the consumer is stuck trying to make them work, BTDT.
Cheers Frank, keep up the good work!
