A New Butterknife Design
« on: September 14, 2011, 06:48:53 pm »
On ZM, there were a few heads in holes where you could not really get a good angle on them with a regular butterknife. Also, it was not possible to get any leverage in some that were in shallower holes.



In my youth I was a carpenter and thought that a modified "cat's paw" would be the ticket. I bought one this weekend and have been working on it.

Here is the unmodified cat's paw.



I cut off the top claws and filed it like so:



looking down and the front end of the paw.



I like how the body is made, it looks like it will withstand the hammering and leverage. I'd like to get a little curve on the bottom edge but I'd have to find a curved metal file.

What do you think?

Not bad, Mark. You're gettin' to be a regular(!) Wall scientist.
I can dig it.
Ya know, when I had my Mescalito mishap, Chilidog(Andres' Zegers from Chile) asked me about it. When I told him I beaked a dead head, he responded that that's how he cleaned dead heads. Since then, I've cleaned a bunch of dead heads with beaks.
Not ideal, but it works. Cheers!

I tried to take out one deadhead on ZM like that, I kept cutting through the head with the beak though. If that wasn't bad enough, I ended up hammering a beak into the crack right on top of the head. It fell right out when I was cleaning the pitch.

Looks like that tool means business. Very cool.

There is/was a deadcirclehead on Cosmos that you had to use a beak behind. Full weight on the stem at a -45? angle. Amazing to me that it held.
Say no to limbers, excavators and retro-bolters. No matter how much he smiles.

How much did you weigh at the time?

beaking behind a deadhead in general smells of 'ripping out' territory

Haha...about the usual weight. If ya weigh 165 it'll be bomber. I gave it all I had to make it fail before committing, as it was in ankles away territory. Creepy.

They are typically about 10" long.

They come in four different sizes. The one I used was the second smallest. The handle is probably seven inches long.
