    Default Ulu's

    Thought I'd share a few photos of a couple of ulu's I recently made from an old circular saw blade and chunks of caribou antler.

    Cool looks great! That sharpened disc with a handle bolted on through the hole would make a killer hide flesher. How did you cut it and grind that nice single bevel edge?

    Default ULU

    Looks like you have some good ulu's there. I too am curious how you sharpened the blade and also got it so shiny? Did you epoxy the handles on the blades? Thanks for the info.

    Andy,

    I put the beveled edge on the entire circular blade (before cutting it out) by putting the blade on backwards on my circular saw and having a friend run it while I ground off the teeth and put the bevel on with an angle grinder. It worked pretty slick, though I was a bit apprehensive at first. Safety glasses and hearing protection are highly recommended...sparks galore!

    I cut out the individual pieces with a jig saw and bi-metal blade.

    Marko,

    I did use epoxy for attaching the blades to the antler handles. I'd like to use some brass pins in the future as well, but I didn't have any brass stock on hand. I used a random orbit sander to clean up the blade and get it shiny before cutting the pieces out.

    Good idea on using a grinder while the blade is turning. I have used a hand held drill motor spinning it into a vertical belt sander. You'd be surprised what you can make with that. I am a little surprised the jig saw cut the blade, I thought you used a plasma cutter. Nice

    Your drill & belt sander trick was going to be my "plan B".

    I wasn't sure if the jig saw would be up to the task either, but the metal cutting blades (Bosch) I have for it are pretty impressive. Expect to wear out at least one of them while making these cuts. Clamps for holding the circular blade down are a must while cutting and the curved radius is probably the max you can do without excessive blade binding. I also used some oil to keep the jig saw blade cool. A plasma cutter would certainly be preferrable if I had access to one.

    I should also mention that I used a plywood cutting circular blade which had small teeth and minimal gullets to grind off. I'm not sure if I would attempt to grind a blade that has carbide teeth .

    I was thinking about some old carbide ones I have. If I try it I think it wise to knock off the carbide first. Great post, thanks

    I think most tipped blades have a mild steel body and so won't hold an edge.

    You may be right there. I will compare with regular blades. Thanks for the advise.

    I also think so.

    This looks like a great project, I've saved a few old saw blades hoping I'd someday find a use for them.

    Beautifully done, Austin. How long did it take you to make these? thinking/planning time? Spoiled prototypes? Once saw a video of a native AK woman cleaning salmon with an ulu. Cleaner and faster than a fillet knife. Beginning of a cottage industry. Thanks for sharing, man.
