I played around trying to get a color mix I liked but eventually just did it to use leftovers regardless of color.

Forum: Lead and Lead Alloys
When I was alloying for handgun I chose a final result of 12.5 BHN based on Fresnell's (sp?) articles. I'd melt any and all lead from any source (pure, COWW, SOWW, range, whatever), then make a...

This is from my calculator that's BHN specific. Using 6.5BHN for stickons hardness add to your 20 lbs-
9BHN- add 1.9lb Superhard, and 7oz 100% tin to get 2%.
12.5BHN- add 5.1lb Superhard and...

From the Rotometals website-
BHN = 8.60 + (0.92 * Antimony% ) + (0.29 * Tin%)
91/5/4 = 14.4 BHN
95/2.5/2.5 = 11.6 BHN

All of my boolit alloy is mixed to produce either 12.5BHN for almost everything or 16BHN for special cases. After PC the boolit hardness will be the original alloy hardness.

Just curious- has anyone ever felt the SSR to get an idea of heat generated? Theoretically the worst case would be just before it's starting to cycle on-off as it nears the set point.
I have an...

Hey Banger did you ever cave and PID your pot :-D ?
Forum: Casting Equipment
I'm pretty sure that's right. I've made 3 PID controllers, the Lee pot and two more for glasswork kilns. One of the kilns tuned well but like yours it took a while to heat up the last 50 deg or so,...

The first thing I did was run the Autotune thing. And for no intelligent reason I did it several times since but can't say they made much difference other than the initial one.
I read somewhere...

That on-off is called PWM for Pulse Width Modulation and is the common method for controlling motor speed and heaters and other things with a digital 'total on or total off' method as opposed to...

Hey psych, I hope you got your controller the way you wanted! I disappeared over a year ago but thought I'd drop in.
The 12v light was only because I had one, and I already had a 12v power supply...

Gonna rain til Christmas I here.
I don't think the alloy is all that critical as far as getting wrinkle-free boolits, or maybe I've just been lucky. I just saw your pic- that's pretty much the...

Where'd your lead come from? How was it described?
Forum: Cast Boolits
+1 to Larry for first bringing up tin, its purpose is to weaken liquid lead's surface tension so that all the crooks and crannies get filled. A few pics showing the wrinkles might be helpful.
Forum: Cast Boolits
In my experience 700-750 pot temp has covered everything. Around 800 is where tin or antimony start to oxidize and separate, don't remember which.
Also from my experience is realizing the 3...

The recognition is long overdue, glad it finally happened. Beagle's boolits and photography skills are top shelf and have been inspirational to more folks than just me.
Forum: Lead and Lead Alloys
Numbers rock when trying to compare thing A to thing B. Possibly a significant efficiency factor is how many of those BTUs/hr get conducted to the lead instead of the surrounding air.
Forum: Casting Equipment
Nice job! What shifted you to an RTC instead of a thermocouple? Goods and bads about both. Good article-

I'll be very interested to hear how they shoot.
So how much lead you got so far? :smile: You may be surprised by another new passion!

Won't the tube get pretty heavy? Maybe not, I don't have a progressive. Clever idea.

Those look really good to me, both the casting and the PC. The scratches on the noses won't cause any trouble. I was able to use my bare powdered fingers to pick them up and even twirl them a little...
