Genius 👍😁 I'll try it out this afternoon, i've had trouble.with dry "shake'n bake" in my nordic climate.. I hope the silicone spray play well with Eastwood Ford Blue powder..
Dette er jo genialt 😁 Takk for bra video 👍 Jeg har hatt trøbbel med "shake'n bake" tørt her i vårt nordiske klima. Så nå er det Biltema silikon spray og Eastwood Ford Blue som er dagens plan! Håper det fungerer med det pulveret..
Great video. i have tried this method using wd40 silicone and it doesnt work. THANK YOU !!!! Can you recommend a silicone spray? Maybe my dust is wet ... I live in the Balearic Islands and the humidity is high , Thanks
The key for me is to not use too much silicone. Too much will clump the powder leaving bare spots. I use generic hardware store silicone spray. The data sheet for it just says "silicone and heptane".
During the baking in the oven the lead alloy recrystallizes, the water quenching of the hot bullets make them harder (if the alloy contains antimony and arsenic, like wheel weight alloy). The water quenching also makes the coat harden quicker, making the bullets separate easier, lessening the risk of clumps.
Wow. How does the silicone do this? I've been using you heat first method and it works great. I get better results with satin finish powder. Gloss never coats well first time. Which do you use? Thanks again for another super video.
I asked the same question to Glen Fryxell (author of "From ingot to target"), as well as to ask if the silicone evaporate through the coating. He wrote: "The silicone is serving as a tacky adhesion layer. It may also be serving as a binder, depending on the chemical structure of the powder used in coating. I have used silicone grease straight as bullet lube before, and it works fine (no damage to bores). My only concern would be the baking step oxidizing the silicone oil up to silica, which is an abrasive. As a general guideline, silicone oils start to degrade (smoke temp) above about 250C (480F), and don't fully oxidize until much higher, e.g. above 400C (750F). As I understand it, most powder coating involves baking at 350F (177C) to maybe 400F (204C), which is well within the stable range of most silicone oils. No, I would not expect it to evaporate during baking. I would expect it to get tied up in the polymer coating."
@@jaycousland9835Hi Jay. I knew black was a bad colour for that. Been given about 4kg of Kawasaki green from a local paint shop. I'll be casting this weekend. Take care mate.
