I'm making a knife for a member with their Walrus for the handle. It will have a copper colored bolster that I will do a lost wax casting for. The blade is O1 using the heat treat that Devin advised me on, which has been working really well for me. I have a bit of shaping to do yet...........

hippo ivoryHmmm, between the ivory 'correction' and the copper colored bolster I think I can guess who the owner of this knife will be :biggrin:

I am hoping you will show more photos of the casting and finishing.
Regardless, this is going to be a fun WIP.
Thank you for posting this.

The casting came out most of the way. I was a bit too cautious about over heating the alloy, so the extra that I allowed came in handy!

What is the bolster material?

Spike, what does it take to do your own casting?

SpikeC

The metal is an alloy mix used to make rose gold, copper and some other stuff to give it better hardness.

Doing your own casting can be as simple as a soup can and a potato or a burnout oven and a vacuum casting machine, with crucibles and a torch. I use the latter!

looks like a really neat Job Spike, Nice knife too. How much clean up is necessary using your casting method. Do you do the slot a bit undersize then file it out to fit?

SpikeC
02-29-2012, 04:00 PM
When the casting comes out as it should very little finishing is necessary, often emery paper is sufficient. I make the slot just fit perfectly in the wax, and the small amount of shrinkage in the casting requires a few swipes with a needle file to finish the fit.

WillC

Thats a great skill to have. Certainly sounds more fun to me than drilling little holes and filing them out.:biggrin:

How would I go about learning about casting?

I am sure Spike will give good advice. I know Jewelry making does this a lot.

love it, has that centuries old fell I wanted.

SpikeC

I'm thinking mustard finish on the blade, and some patination on the copper.
It's really feeling good in the hand!

Very cool, Spike. How do you guard against messing up the temper when you cast the ferrule?

SpikeC

Thanks for all of the positive comments, guys! That hunk in the background is a chunk of maple burl that my nephew brought over for me.
Most of this knife is from specs given to me by Son.
