Here is what I am doing for molds for foam core grips. It is a very simple mold made from Aluminum, has the profile CNC machined, and a removable mandrel. Since you are covering it with a carbon sleeve anyway you don’t have to have a mirror smooth finish on the mold, this drastically reduces the machining cost. With this design you could reproduce any grip shape you could dream up and have them all be exactly the same.

That's a beautiful mold. Very well done. I'd love to see the finished project. But it can be done much easier and at far less expense with the method that will be in the volume 11-2 RodMaker (or so). Something that doesn't require machining or any expensive materials. And almost anybody can do it in their home shop with no special tools. Stay tuned.

Yes I read that in the story, I figure something like plaster or a silicone mold would be easier for most people. You always end up using what you are comfortable with, for me that is CAD and CNC. Other people have different ideas and they all get the job done in the end.

I am getting them quoted right now. The cost will vary drastically depending on the length of the grip that you are making. The molds for a short foregrip or the parts of a split grip will be much less expensive than a mold for a 12” solid grip. It is all about the amount of metal in the mold and the spindle time to machine out the longer cavity. If you wanted to do it in serious production you could make multi cavity molds, a 5 cavity mold would be much less expensive than 5 separate molds. My next design will be a single mold to do both parts of a split grip.
