Newbies often start a thread this is probably a dumb question but …… The only dumb questions are those ask with the intent to show off what one knows or impress the class. Those seeking assistance even on an elementary level are not dumb. The fear of appearing dumb may be restraining others from asking the same question. There is some tendency to fault askers for not using the search functions or not thinking things through. The search functions do not work real well for the newbie because of the vocabulary of terms. Thinking things through also comes with experience. I recently cut my handle of prematurely on a lathe project. That caused all sorts of grief. I was seriously considering starting over. That sort of mistake teaches you to think further ahead. I have had a small stroke this last year. That has caused problems with memory and thinking processes. This group has been very helpful and I really appreciate the quality of help and experience available here.
