Difficult to take the pictures - oh Yes - but still - the Pre-Cut Gear looks nothing short of Amazing It is harder to get a good idea about the finished item, with all it's facets - but you are Happy and that is what matters most (I most likely would be too) Per
That's some mighty fine hobbing there, Chris! Kim
With the worm diameter about the same as the worm wheel width, you tend to have a high helix angle on the worm. This hobs away a lot of the tooth shape at the edges of the worm wheel and they take on a triangular shape. Hence in full scale they tend to use a worm diameter 1.5x of the worm wheel width or more. Then the edges of the worm teeth look more like involute teeth. -Doug
Hello Chris,Have you measured the between centers distance; Worm to Wheel?Mike
Boy, tapering the sides of the worm gear changes the look and tooth profile dramatically, doesn't it? Kim
You make cutting gears look easy Chris. Good inspiration for those who buy their own instead of making them. For those who want to cut their own I have the spread sheet for making cutters and the different gears just PM me. I can’t post spreafsheets in plans a drawings the file is too big. By the way Chris can you take a photo of that arbor press I see a hand wheel on it. Just interested in seeing it. Don
