Dubl Duck FAIL.

I was almost finished restoring this Dubl Duck. I brought it back from disaster. I think this is what you call Cell Rot.:Attachment 53096

I was scaling it in Masecraft Polyester Pearl (Appropriate for a Pearlduck Dwarf).

Everything went well until I pinned the hinge. The blade was not centering, so a few more taps:

Dang. Now I gotta order more material. At least the blade is done.

Blade looks good, scales look good...

...my guess, based on the pin, is that you were hitting too hard and the force of the blow, rather than the tightness, is what cracked the scales. Make sure you're using a light hammer, or really choking up on a heavier (read 8oz) one. Many, many, many light taps will do it.

Looks like a really good job, otherwise!

I'm pretty sure it was cause I was trying to force the pin in a direction it didn't want to go. I am using a light hammer. Thanks for the input.

I have found that if the blade isn't centering, it's tricky to make it do so with the hammer. I test fit all my blades with microscrews first to try to get the centering issues sorted out ahead of time.

Welcome to the world of restoration. I think we have all at one time or another cracked a scale followed by choice expletives. Rule: Always have a little extra material. :idea:

+1 to that. I've recently started using the screws to test before pinning and its made life much easier and safer.
Could be worse mate, I think a lot of us have busted blades trying to correct alignment issues. Let us know how it turns out.

Edit: Blade looks great too BTW

sous, i think you did a great job on bringing the blade back from the dead & the scales choice is killer! sorry about the crack:( how long did it take you to master the art of rescaling a SR? if you dont mind me asking.

Holli4, yes, I check mine first with Microfasteners too. Just didn't line up after peening the front.

That blade turned out very pretty, looking very nice with the pearl scales and red wedge. Those scales look real nice until the obvious.

Thanks for the strength to take the pics and post, including the close up. Breaking things is part of learning. In a selfish way, we get to learn by your efforts.

That really sucks! Those were turning out beautifully :rant:

Well I'll let you know when I've mastered it...
But seriously, It took me about 3 scales to get one I would be happy to sell. Surprised myself tremendously, since I never did woodworking before. Check my posts for my progression.
Thanks for the kind words.

That was my intention. My lesson et su lesson.

For centering blades I only glue one side of the wedge and only "snug" the wedge pin. A little flexing of the scales will sometimes help to center the blade. Nice save, I'm sure it will be a great shaver...

If you test a blade and it isn't centered, how do you center it?

I find it usually is because the holes weren't drilled straight.
Drilling the holes a little bigger, thus giving what we PA Dutch call more Schnully, sometimes works.

-Keep one scale thinner than the other...the thin side will bend more than the other. The difference is very slight, doubtful that the eye can even pick up on it.

-Keep the wedge pin just snug, then tighten once you have "flexed" it to where you want it so that the blade closes in the center. This is the wya that I primarily use. This means you only glue one side of the wedge...obviously.

-Some have even bent the blades...do this with obvious caution. I've only been able to break blades to date personally.

I'm sure there are many other ways, but that would be a question to ask in the workshop...

Nice job all round. Shame about the break but if she was straight with the microfasteners good chance you misaligned at the wedge end when peening. Iin that case, best to pull it apart & start again with 'tiny, tiny taps' like Happy Gilmore. All you lose is some washers & not hours of work. I always leave the wedge end less than fully snugged till the pivot's in process then nip up both ends gradually, like doing up wheel nuts.

I used this technique today and it worked like a charm. THanks!

Cool. No more broken scales. I sure I got the idea from SRP probably that Glen fella :D

I've had this issue a few times and if I can't do anthing at the wedge end then I"ll simply add one or two more washers on one side of the pivot pin to try and straighten it out. This has worked for me a few times.

By the way the blade and scale look fantastic!
