    Default Wolverine Sharpening Jig

    Hi All!

    I've recently picked up a GPW sharpening jig for my lathe chisels, and it looks quite similar to the Oneway Wolverine jig. The GPW jig gives me pretty much the same setup as the basic Wolverine, for a lot less outlay, especially postage.
    However, the Wolverine stuff has some nice accessories, but I am not sure if they are compatible with the GPW jig. Does anyone know how thick the square tubing on the Wolverine jig is?

    If the two are compatible, I was considering grabbing a few of the accessories from the US.

    Thanks very much,

    Craig

    Default Further explanation...

    The photo below shows the info I am after.

    "A" denotes the piece of metal that I'd like to know the dimensions of.

    "B" denotes the square tubing which will determine compatibility with my existing GPW system.

    The second photo shows a skew grinding jig which I am hoping will fit the GPW system. The final the new Wolverine blade grinding jig, which I am also hoping is compatible.

    If these are compatible, it means that anyone that has been admiring the Wolverine system, acquiring some of the gear to use might become a lot more attractive and affordable.

    Hi Craig

    I note that the GPW is built from "steel and aluminium". As far as I am aware, the Wolverine is built from steel and cast iron.

    What part of the GPW is aluminium?

    Regards from Perth

    Default Just checking...

    Derek,

    I went and took a good look. As far as I can tell, it looks like it would be the part that is secured to the board under the grinder into which the square tubing slides in and out of. For lack of knowledge of the technical term, I guess we could call it the "clampy" bit

    I'm pretty sure that's aluminium on the Wolverine too. I can measure mine up this evening.

    Hi Colin

    Will you confirm that the chisel tool rest on the Wolverine is cast iron. That is the important item. The base looks like extruded aluminium - perhaps it is steel? I would hate the extensions to be aluminium, however, as this would make them flexible. I imagine they are steel.

    Craig

    Is the tool rest on the GPW steel or aluminium?

    Craig, the piece marked 'A' in the picture is 63mm wide by 73mm high at the apex. It's about 60mm high at the shoulders, and is 3.2mm thick. The sides of the V are 40mm deep internally, and 51mm long. They are also 3.2mm thick. The shaft is thick walled square steel tubing, 19.3mm square, and just over 2mm thick.

    Hi Derek, the base clamps look like extruded aluminium, I'm pretty sure they're not steel. The chisel tool rest (the bit to the left of part 'A') is steel plate, 6.3mm thick or so. The post is thick-walled square steel tubing and the chisel rest can swivel and lock. In fact everything except the clamp parts are steel.

    I've lost this post once already and don't want to risk putting my fingers in the wrong place again, so I'll post a couple of pics in a new post.

    Derek,

    The tool rest is steel. It seems like a very solid set up.

    Gents,

    Thanks very much for taking the time to grab some measurements. The end piece I marked as "A" on the GPW measures: 61.74mm wide, 62mm high at the shoulders, 75mm high at the apex, and 2.8mm thick. The sides of the V are 40mm deep and 51mm long. Also of the same material as the end piece. The shaft is 20.23mm square made from 1.97mm thick steel.

    I would hazard a guess and say that the wolverine gear will be compatible.

    Craig

    I know this thread is rather old now but I was just wondering how you're finding the GPW jig now that you've had time to use it? Does everything lock in nice a solid?
    Thanks

    I've used it a few times now and am far from being proficient. It locks in very solidly and seems to be a good little unit. I just need to spend some more time practicing my sharpening skills

    Very impressed with the jig and the service from GPW.

    That's good to know! I was looking into the wolverine jig when I found out about this one. A steel platform that is solid when locked in place will be very nice indeed. I'll see how it goes!
    Thanks
