Frankford Arsenal Drop Out?
« on: February 20, 2019, 08:52:30 AM »
Hi, I recently saw a video where Frankford Arsenal Drop Out is used to condition molds for lead casting:

I have always used a butane lighter to soot new molds.

The Drop Out product:

Has anyone here used this product to condition new molds? How well does it work?

Regards,
Richard

Hi Richard,
    I've been using a liquid called NEI Mold Prep and it works pretty well. The Frankford product sounds interesting to me also because being dispensed from an aerosol can would make it easier to put on an even coat.  Although I haven't got any casting planned for the near future i just ordered a can.

I don't condition mine. I bought a used one that had been smoked, it didn't work any better. Just a light tap with a plastic screwdriver handle on the metal part of the handles is all it takes to get them out.

I keep an old candle in with my casting stuff and just smoke the mould every 20 rounds or so.
The FA stuff sounds interesting, but just adds more cost to the casting process that is unnecessary, IMHO.
200 years ago, it would not have been an issue. Just sayin'...

I tried the Frankford spray and it was more trouble than the cost. It puts a thick pebbled coating inside of the cavity and if you spray too much, you can loose a half a thousand on bullet diameter.

If you want to coat the cavity of a mould, use a wooden match. Touch it to the molten lead and it will ignight. Then smoke the cavity with the flame from the match.

For my self, I cast with clean mould cavities. I allow the lead to cool for a few seconds, and do like Hawg does. I tap the mould pivot joint with a rawhide dog bone and the bullet falls right out.

Hi Brad, I have seen a few reviews like what scooby reported where the Drop Out can end up too thick if over sprayed. I think the secret for success is to apply only a light coat. I understand that the sprayed product can be cleaned off the mold with acetone. A lot of other reviewers claim that Drop Out is great stuff. If you use the Drop Out, please report on how it works for you. The next time I cast, I will give it a try and report back.

While I do soot my molds with a butane lighter, I sometimes need to whack molds with a small oak board  to release the casts. It would be nice for both me an my molds if I can avoid the whack.

Regards,
Richard

I got some Drop-Out to use with my .36 Colt mold from Eras Gone, previously I smoked molds with a yellow acetylene flame off my Presto-Lite torch. I used a light touch applying the Drop-Out, and give the mold a light tap with the stick I use to whack the sprue cutter. The bullets drop out easily.  If memory serves I first learned about the stuff from Duelist 1954's site.

If I want to soot my molds, I just light a stearine candle. Both sooting and soothing

One issue to consider with the spray on product when casting conicals is that you are trying to hit all of the curvatures and corners with an even coat. And the spray comes out fast an wide just like a can of aerosol paint. With the fist squirt into a mould half, you will not cover the entire cavity with the first shot if you are attempting to just add a light/thin coat. There will be voids in parts of the lube grooves and perhaps the tip of the nose portion. Then when you change the angle of the can to get the missed spots, you end up over spraying portions that already have an adequate layer. So be prepared to to be efficient and add a degree of finesse.

Hi, tired of casting two 0.490" balls at a time I purchased a new Lee six-cavity 0.490" mold. This new mold gave me a chance to test the Frankford Arsenal Drop Out. A light coat of the Drop Out worked great. Good balls from the first to the ~500th were produced, no sticking of balls at all. Never needed to wack the mold to release balls, they just fell out.

In the past I have smoked molds with matches, candles, butane lighters, and even burning kerosene. None of those methods could hold a candle (pun intended) to the Drop Out in performance.

BTW, since such a light coating is required, a 6oz can of Drop Out should last many casting lifetimes. I got a little of the spray on my fingers, but acetone took it right off.

Regards,
Richard

I bought a can of the spray Drop Out years ago; I used it to lightly coat a couple of aluminum molds and it worked quite well. I held the can a ways away from the mold and that way you can regulate how much of the graphite is being applied. Doesn't take much! Lately, I just use a match to soot the cavities of my aluminum molds.

I just get the lead to temperature, get the mold hot and cast  way. End up with beautiful and uniform castings.

As I mentioned above, I got a can of the Drop-Out many years ago. I used it on a couple of new Lee molds and it seemed to work well. However, I have not used it in over 15 years, and all I ever use now is the smoke from a match or candle on aluminum molds. IMO, if the ball/bullets are sticking in the mold, there is some other issue that should be corrected.
