  • Someone with moulder experience?

    We are going to be using a 5 head SCM moulder to put three half circle shapes into the top of a 2x8 up to 1” deep. All spruce. We need to buy heads and knife stock to make the knives. I’m just wondering if someone with experience with this can provide input on how many knives to use, and what type of steel or heads to get. Finish is unimportant and we will be doing mass production. We are thinking to use 2 heads to reduce drag on just one motor. The bore is 1-13/16”. Extreme speed won’t be needed at this point.

    Welcome to the forum. I would be interested to learn how this could be done. You are describing ''scalloping''?

          last moulding company I spoke with was a third generation business. At that time mostly all they ran was high speed steel. They ground all their own knives. The 18 percent Jack is talking about is 18 % Tungsten. Dimar and others sell that.
