Remember. I do not cast anything. It has to be something I can soak in lacquer and CA.
Ok so, you mean, anything that you can stick/glue to a brass tube and then build from there...????
That is even easier than casting, I won't even start giving examples, I may still here after Christmas.
Where to look...??? Horizon in your limit but, why not start on the room you are in, at the moment, look around slowly and think, every room of your house will give you something, kitchen is one of my preferred places to get "stuff" to make pen blanks with but, the house alone will give you endless opportunities and when you are done, or you think you are, go in the shed, garage, backyard, everywhere will be something...!:wink::biggrin:
You want the easy way but that will not give you the, exclusivity and the self satisfaction to have come out with the idea all by yourself, that makes the whole thing a lot more interesting, well..., for me it does...!
Good luck,
Cheers
