How I pour a pewter knife bolster
« on: October 13, 2015, 08:39:15 PM »
I first attach my handle material to the tang. I then mark off the length of the bolster that I want with tape. Next I reduce the area with file to permit the pewter material to fill in the reduced area. I wrap manila folder paper around the handle to form a dam to allow for excess pewter to flow around the knife handle and secure with tape & cord to prevent leakage. I secure the knife in a vise with the blade up and proceed to melt the pewter. When the pewter is melted I flux the melt then pour it into the paper dam. When cooled I remove the paper dam and inspect for voids – fill them if necessary. Shape pewter & handle material using sanding wheel and sandpaper – polish – done.
Note this is also my way to pour muzzle caps except I drill cross holes for the pewter to “lock” into.

 I have two questions. What do you flux with and why? I have never fluxed pewter and now think that is the reason my pewter jobs are hit or miss, Thanks,.............JZ

I use candle wax - same as I would when I cast bullets. I do this to get as much of the impurities out of the melt so they don't end up with a void or outgassing causing bubble voids.

Thank you for the detailed tutorial. I love seeing a knife with a well executed bolster such as you have there.
My first question is: What is Pewter...???
More specifically...what is the composition of the Pewter you use..?? I did a brief search and found the term "pewter" appears to cover any of a wide variety of alloys..it doesn't seem to be well defined.
I'm wondering if straight roundball lead would work..??
How about something like linotype, or "hard-cast" bullets..??
Thanks...
Don

Don, the "pewter" that I used for this bolster was purchased from Track of the Wolf. I have bearing babbet metal that I have used. I have used linotype also. Pure lead can be used but it is too soft and discolors -- I like my bolsters to look like nickel (shinny). Hope this helps.

That definitely helps. Thank you.
I have a quantity of linotype that I might try. I doubt it will polish up to be quite as pretty as what you are using, and may not hold the beauty as long. Those aren't issues for me however.

I frequent thrift shops and will pay up to $2.00 for a good sized piece of pewter-ware.  Cut with a band saw or side cutters and melt into ingots.

I have used linotype and it will polish out very well (at least the stuff I have will) and, like Crowbarforge, haunt the thrift shops for "pewter". Most of the time it is really Britannia metal which contains tin, antimony and copper. I prefer the Britannia metal when pouring knife bolsters as there is no lead to cause problems when the knife is used around foods. Linotype does contain some proportion of lead and I just don't bother with it anymore. BTW, when you cut up a "pewter" mug or other thin item, save some strips to use in soldering up pin holes in your casting.
