    bow drill bearing blocks

    Anyone else use a premade bearing block for bow drill? I have two, both made for me by a good friend, one is a micarta version and the other (and better version) is a skateboard bearing embedded in a leather sheath. The true advantage of the skateboard bearing block is that it eliminates any chance of the bearing block heating up (sometimes happens with solid bearing blocks)

    I lashed out and added one of the ESEE ones to an order of knives from overseas a while ago. Unfortunately I haven't used it much since then but being metal it does heat up a bit in use. The flip side though, is that it is made of 1095 so doubles as a very good striker.

    I have a couple of knives with micarta handles that have a divot in them. I have noticed that the hole/divot gets a lot deeper pretty quickly with use, so I have stopped using them for that purpose. There are a few knives around with metal lined divots in the handles which seems to be a good compromise. Have you had any such problems with your micarta block wearing through?

    no so far Steve though I have only used it once or twice as I got the skateboard bearing block soon after I got the micarta one and it made the micarta version superfluous.

    Thanks Dean. I am certain that the skateboard wheel is far more efficient but I was watching some videos on how to make home made micarta the other night and this has piqued my interest. Maybe when I get back to Australia for good and have a workshop again I will play around with building a micarta bearing block lined with a steel divot from scratch.

    I also really like the idea of those ESSE (or unbranded Chinese OEM versions) of a striker and bearing block combos and have one in my watch list, but as I have these two I never really saw the point. The heating issue is quite problematic from what I have heard and is not isolated.

    The ESEE is a good bit of kit but stupidly expensive for what it is (I wouldn't recommend buying it for the RRP). The heating issue is manageable if you wear gloves (I normally carry leather gloves in the bush) or pad your hand with a rag or hat (I usually use my bush hat). I was surprised to read that the micarta heats up too much as I thought it was just heat transfer in the metal, but now that I think about it, the times I have used the bow drill divots in micarta knife scales, it has definitely resulted in scorching of the micarta.
