    skeletal frog

    a diy frog. construction is stainless steel a brass rivets (pun intended).

    designing the parts was made a lot easier because there's a lot of information on frog anatomy on the net.

    Hey, that's great! How big is it? What type of material and what thickness?

    How long did it take to cut?

    Inquiring minds want to know!

    Thanks!

    -Jeff

    That is cool...what are the odds of you posting up the DXF so I can make a frog of my very own?

    A lot of work went into that so I won't cry too long if you say no.

    sorry took me a while to respond I was on vacation -- the size of the thing is about 4 inches long, three inches tall in the crouching position. the material is .032 inches thick stainless steel.

    The dxf is attached. as you can see, its has no assembly information, I'll leave that to the lucky assembler. All the round holes on the drawing get cut out, and the thing is assembled by rivets. The rivets are formed by placing a brass brad through the hole, snipping with plyers, and the peening over with a punch and hammer.

    enjoy,
    owen

    Hey Owen, you gotta laser cutter we can borrow

    Think I will scale it up a bit so a bit larger cutter will be usable.

    Yeah, I am thinking aluminum, don't have any stainless, now that I think about it there is some brass sheet in there, brass, that would look really good, yep, brass it is, I now have a plan

    note: there are bends in the some of the parts. might be an issue depending on how thick material you use.

    Dave, what is your opinion or suggestion for holding the brass sheet down, it is 6" X 24 ' .025 thick ?

    I was thinking a very light spray of contact cement on a Plexiglas substrate.

    Owen ?



    Thanks
    Ken

    wow, you guys get to _mill_ things. all I get to do is cut them with a boring old laser.

    read: I dont have any experience with machining brass.
