Cork Blocks

[J.McDonald Knives]

Anyone know where I can get cork in blocks? Looking for about 1 1/2"x1 1/2"x6" or even 5". I'm looking for the same grade as what you would use on fishing rods. Thanks.

But I don't know if the yoga blocks are the same grade as the cork used on fishing rods. Anyone have more details about the yoga cork blocks?

I'm going to talk to Maryland Cork on Monday and talk to them. Seems like they can get me what I need. This is for the bowfishing knife I'm working on.

I have a dumb question, can cork be stabilized?

 

[Jared Stenoien]

I'd assume so, but why would you want to??? You'd be defeating the purpose of using cork in the first place.

I figured it would take a high gloss and not get as dingy.

What yall think about the design idea?

I think that the steel mass in the knife may be too much to make it float (weight of water displaced v upthrust )...maybe consider downsizing as much of the steel as possible to reduce weight, less than 1/8 thick and less length..just my 2 cents.

 

[J.McDonald Knives]

I will start on the thickness once I get the prototype made. After that I will work on the width and then the length.

Just an idea Jacob. You could get the cork display bases from Hobby Lobby. They are about 1/4" to 3/8" thick. Then do a stacked handle like you would on a leather stacked handle. I believe they are like 8-10 inches in diameter. Just cut out the size pieces you need.

Pimpin,

Steel weighs .2833 lbs/cu in. Water weighs .0361. (I actually knew that off the top of my head, I deserve a beer) That means you need eight times more air than steel for it to float. Or 16 times more cork than steel if the density of cork is centered between air and water, etc...

You're going to need a very minimalistic blade and a very buoyant handle. Perhaps hollow plastic?

The cork grips on fishing rods are not made of one piece. They are a series of rings that are glued together and then turned down to the shape of the rod.

 

[SteelSlaver]

the specific gravity of cork is Cork is 0.24 and it weighs .00868 #per cu inch. a 6 inch blade 1" wide of 1/8" material with a flat ground to an edge would weigh under 3 oz. with a taper and fillet type profile. Thats with out any handle attachment metal a ferrel and a 5 inch piece 5/16 all thread over 1.5 oz. By the time all is said and done you need to float about 5 oz of steel. Trim it all down as much as possible for 4 oz (hole in blade aluminum cap and ferrel)and you would have a bit over a cu inch of metal and need about 12 cu inches of cork. Maybe 1/16 inch stock on the blade and 1/4 inch all thread will do it.

So its about 12:1 cork:steel. I will work out the details as I work on the prototype.
