    Question Crushgrind Mill Drill Question

    Has anyone ever used one of these for their Crushgrind mills? If so, how did it work compared to other methods? Is there a place that sells Mill Drills in the US?

    Thanks!

    noah, woodcut store sells them, but for $84.00, my forstner bits will do just fine. The time savings, what there is, is not worth the extra expense.

    That's cool! If I have seen this before I bought the set of forstner bits, I might have been tempted!

    I have used one and it is a pretty slick unit. Saves swapping out bits especially useful if you are doing a production run of mills.

    Any US suppliers?

  7. I had one before and had to sell it with my lathe when things were tought. I have just bought one again because if you are going to make more that two mills in your lifetime it is absolutely invaluable!

    Where did you buy yours?

  9. I purchased mine in Sunny South Africa, but I am sure you can purchase it online.

    I have made my own and sold a few to club members. My design is a little different in that it accepts a forstner bit in the end so that one can drill all 3 holes at once. I sold them for $50.00.
    Always drink upstream of the herd.

    I'd love to see a picture of the one you made if you have one available. Thanks!

    I've had a few folks show some interest in my home made Mill tool so here is a picture of the prototype. As I said I have sold a few to some of our club members here in Edmonton. Not sure I want to get into full scale manufacturing of these as I'm not sure if I've made enough of a change to get around any patent laws. This one was made from some barstock I had on hand and had to be welded together. Following ones were made from one sold piece of 1 1/4" round bar machined down. The cutters are 1/4 HSS tool steel.

    If you ever change your mind about selling them, let me know. I'd gladly order one!
