Ok, sorry bud I get it.
The branding iron need to be a soft metal, its not going red hot just to boiling.
Make up shapes for your iron, what ever shapes you need to complete the brand. If you need two or even three shapes get em made up. Each shape needs a handle.
suspend the irons in a boiling pan of water, when the pan of water is a rapid boil make your strike.
The brand area will go red and make a scab exactly like the iron, dont touch the scab for a day or two, when it is ready pull scab off and that brand will be there for a very long time.
I have some pics of irons and brands if ya want me to put some here.
If ya want me to do a post on the caurt pen just let me know.
