Recreating the vintage red plastic handle with a mold casting

For any of you with a vintage Mark 5 that needs a replacement handle from
ShopSmith, you'll find that the plastic part on the new one is different from the old red vintage version

[ATTACH]3711[/ATTACH]

Since my 1955 Greenie Mark 5 didn't come with one of the two handles, I purchased one of the replacements.

I want to replace the black plastic handle by recreating the vintage style larger diameter red one. I thought that making a casting of the old handle is the way to go. My problem is ......I never made a casting before.

Before I blindly go out on the internet and start searching around for info on how to do it, I wanted to post this thread assuming that someone in this forum might already have some experience in this area and if so, I'd like to hear your suggestions on how I should proceed.

I think the best way to make a cast for this type of project would be to use a very hard or dense wood or even a metal cast. I think the metal would be best but I also think the wood may be the easiest to do. That is if you are good at wood carving anyway.

you might be able to make a casting of the threaded inside of the handle and then make a a mold of the handle around the casting of the threaded part.

WELL! You have indeed made this thread VERY interesting. Any body know what the non-threaded end(inside the handle) looks like?

It could also be done by making a blank and then drill and tap. But I was wondering if you could not just insert the handle into the mold and make the plastic piece around that as well.

Been there done that(on a new one which I do NOT like! It is NOT threaded. It will rotate on the shank(if torqued enough). I asked the previous question in case SOMEONE has broken one off the shank.
