    Default Cup washer or flat easher??

    Hi.
    When you install new scales on a razor do you use cup washer (finishing washer) or flat washer.
    I've just watched a video on "making Dovo Razor" and the guy peening the brass pins is using cup washers, two on both sode.

    Which is best to use??

    Thanks
    Jacques

    Dovo Pins(silver BTW) come with cupped washers, they work great!!! However when I am using Brass pins I have used both cupped and flats it is more esthetic's then function for me!!!!! YMMV

    Gssisgun,

    Which do you prefer, the cupped or the flats for
    looks? Like you said, I got some of the
    Dovo replacements and have noticed they
    are cupped, but haven't used them yet.

    Several of the restorers here using a dapping block to dome flat washers. This adds some visual interest as well as preventing the washers from cupping as the pins are tightened. Here's an example:

    +1 exactly
    These work out as shown here, or you can actually work the pin and the washer into almost a contiguous unit.....OOOOoooo big word use hehehe
    I don't think either is better as per function they all hold the razor together, the Dovo system is by far the most user friendly, IMHO, and also the most expensive to use.......

    I like the kind Kyle posted- DIY domed washers. I have yet to try it. I use flat washers, really because I HATE the look of the DOVO pin type. Also, doubt they would work well with adjustable pins, huh? Mainly cause I hate them though...

    This may be a dumb question,but would the domed washers also provide a little tension on the pins?
    And also how do they react if the pins need to be peened later?
    I'm a newby at this so I'm just throwing questions out there.

    Now that is a good question.....
    I think in theory that they would create slight tension, and re-peening should not be a problem although it might not be needed as much...Anybody had one long enough to have to tighten a pin?????

    I haven't noticed any difference between domed or flat washers. If a pin were tightened enough to create some kind of spring effect within a domed washer, particularly a stainless steel one as shown here, it would probably split a wooden scale. Brass, being much softer, probably has little "springability." It would just bend. I think the domed washers are purely aesthetic. To me, the biggest advantage, is that you don't risk a washer cupping -- where the center is lower than the edges. That really looks bad.
