First attempt at a pewter nose cap

[Commodore Swab]

Most everything I do is early enough that it does not require a nose cap. However, this very early conversion did have one (the original) so I've attempted to try to pour one. There is still a bit of shaping to do but I think its turned out pretty decent.

looks good so far! :idunno:

Nothing wrong with it, it's a heck of a lot easier to pour pewter than bronze.

looks good. and i have to agree about the bronze!

Looks great!

That looks great -- you did a fine pour -- you are now an expert .

Looks perfect !

To pour bronze you need to adjust the alloy, I add varying % of silver to the metal to get it to flow when I do investment casting.

I've poured bronze before, personally as much as 25-30 pounds. Working with a friend 2-300. For larger pieces (lost wax) silicon bronze was used.

Hi C. Swab I admire your skills and the pictures you post are pretty cool. I've seen large pours happen but never actually handled the crucible. My experience lies mainly with investment casting for jewelry open crucible and hand held torches and small sand casting. I have recently been experimenting with red bronze and found flow problems as the metal has a tendancy to cool too rapidly. I resolved the problem by adding silver to the mix. I found anything over 10% to change the color , 3% is the minimum amount to begin increasing the flowability of the pour.

Try silicon bronze, it usually pours nicely. Ive also found that copper is your friend.

 

[Gustavo Hoefs]

Thanks for the reply, are these more yellow or is there a red silicon bronze. In my experience there lots of subtle variations in alloys and they seem to vary from one supplier to another. Which ones do you like and have you succeed most consistent results with.

It depends on what Im making.
