    Hi Lee. That was my guess too, but thought I would ask.

    I remember that incident with Dave Sheldrake and his stock of stuff was pretty bad. He couldnt tell from sheet to sheet what the settings were going to be. Unfortunately he had a large amount of stock on hand for his business. I assume he has worked that out since.

    I tend to buy what I need as I go. An advantage to living just a few miles from good sources of supply. I also spray all my sheet stock with either lacquer or clear shellac as soon as I get it home using an HVLP sprayer so even if humidity is changing it affects my stock more slowly. And the coating also makes it easy to deal with any soot if my settings are not spot on.

    If I were to say "cars run on diesel" would you consider that to be true, or worthy of a correction? Perhaps that is too obvious because we all know that cars can run on a variety of fuels (even wood and candy bars), but some readers here may not realize that not all CO2 lasers use water cooling.

    I think the part about saying that you don't know the difference is unnecessary, but I do think it is reasonable to point out that your statement, while not technically wrong, is not correct either.

    I think if you and others read the entire thread and the whole statement you wouldn't come back with some of these bone head statements. I said co2 lasers are water cooled and he said thats not true statement.if you read the thread instead of just a few words here and there then jump on me you would allso see I said not all co2 lasers are water cooled. But he said my statement was not true implying that NO!!! co2 lasers are water.
    cooledNothing needs to be pointed out I'm well aware that some co2 lasers are air cooled and some are water cooled.nuff said on the subject.

    You clarified that not all lasers are water cooled after Glen raised the point. I think it is reasonable to make that clarification, I don't think it is necessary to insult.

    Rich, I'm pretty sure it's simply not worth trying to convince him of the error of his ways. Anyone else who reads his original comment and my reply will understand the distinction and its significance

    Rich, while I agree with you on the desire to clarify is good for anyone new, the manner of the correction that Glen posted was way over the top. I'm still what I would call a novice to most of you guys here but I think that for Glen to personally call out Bert's post and really impune his knowledge is over the top. Even I would have been a bit miffed​ with the post. We're here to help each other, not downgrade each other. At least that's why I'm here!

    Thank You John and Rich I somewhat agree that clarification might need to be pointed out. Yes I did say after the fact that not all were water cooled but I wasn't thinking its a new guy and didn't think I needed to point that out since I thought we were talking about glass tube co2 lasers . Thats what I get for thinking or not thinking, but yes I was ticked a bit over Glens post.oh and just to point something else out there are water cooled RF tubes.

    Indeed, I think I recall having read that in, what, the 3rd post in this thread? ;^)

    Yup I did Dave, I ended up dumping it, over 1,000 sheets in the end (2440mm x 1220mm sheets)

    Now everything is stored in an environment controlled room at a fixed humidity and I don't get any more problems
    You did what !
