not saying that you are lying or anything, but how can a measureing tape be off by a quarter inch? where was it off at? the overall length?

I dunno how, but Marc ran into the same thing! You don't notice the quarter of an inch error until you read it in the higher numbers. The last one started varying at the 14 inch mark, and gradually evolved into a 1/4 inch difference at 23 inches. Now, this could cause sizing problems with custom sized hats. Especially if the customer was measuring with a Chinese tape measure, and I am measuring with a USA made one that is dead on in accuracy.
I first noticed this Chinese tape deal when I first started selling hats. I had two tapes. One was an old cloth tape from my moms sewing kit.(still new in pack when I got it) One was a brand new Walmart bought tape, made in China. I would use them interchangably, and that is when I caught the discrepancy in accuracy. When I told Marc about it, he told me he had run into the same thing!!!
My vintage tape finally bit the dust, which sent me to other places besides walmart, but all sold the same chinese made tapes. One was under the reputable "Singer" name!!!!!! It was an eight of an inch off at 23 inches. I eventually had to buy a 120 inch long quilting tape, that was accurate, thank goodness. And cut it off to a workable length.
don't own any of Fedora's or Adventurebilt's products, and to be totally honest, I have to scratch my head at some of Fedora's posts ( personality gap...something ), but one thing I can certainly identify with is his passion for quality.

I am quite sure I have more than you scratching their heads, so you probably are in good company.
Some see me nothing more than a detractor of some brands of hats, but those that know me from the get-go, understand where and whence I am coming from. Years ago, after spending literally thousands of bucks on various hats, I felt like I was getting ripped off. I threw myself into studying the craft of hatmaking, the history, and spent alot of bucks on ebay buying up vintage hats that don't suffer from the taper problem.
I figured if I was to ever own a hat that I felt was worth the money, I had to use the best fur in that hat to pull it off. And that is why I went with pure beaver, as it is historically known to be hands down the best fur to construct a hat from. While realizing rabbit was used in the first 3 film hats. I had to make a tradeoff, of durabilty, over film accuracy. And did so. I don't regret it, although if I could find a stable, yet accurate rabbit felt, I would certainly offer that. Akubras are more stable than the other brands, but I would want something better than Akubra's rabbit. Not dissing Akubra now, so don't point fingers. But, I have seen vintage felt that was far superiour to anything out there today, in rabbit fur. Now, I was told by an old timer, and an Akubra fan, that like other hat factories, Akubra, years ago, changed something in their feltmaking. What? I have no clue, but have to assume they run their bodies fewer times through the felting machines today. You must understand that the number of times a body is run is very important in later shrinkage and taper. The hat body really does need to felt almost completely prior to stretching it out to make a hat. One way to increase productivity is to lessen the times spent on particular operations. I submit that all factories have sucumbed to this, and this is the reason unstable felt is used in probably 99 per cent of all factory hats made today. I don't exclude my own factory from this, by the way. The good thing about pure beaver, is that you can get away with this a little more, and the hat won't suffer as much as a rabbit hat would suffer at incomplete felting. Beaver, without the much needed mercury, (or whatever they currently use, perhaps hydrogen pyroxide)will still felt quite well, whereas, rabbit won't. It is a no brainer that the mercury treated rabbit hats of yore were felted much better than what one sees today. Nothing has yet replaced mercury at raising up the scales on fur as well. And this is very important. That beaver does not essentially require mercury is why it is a better fur to use today. But a real mercury made pure beaver hat, has no equals, and this was common knowledge once upon a time when men knew more of hats, and the felt used to make them. Probably more than most wanted to know, but there is a method to our madness. Fedora
