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's so fun!!!

that's cool

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

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 thanks a lot, thats really nice of you to post that up. :cheers:

Dave,
Did Owens frog File open fully in OneCNC for you ?

I got a single line in MCam.

Yeah, that was what i got as well, maybe Owen sent the one for a stick frog :D

heh. WHADDYWANTFORNUTHIN!?

actually, I screwed up the file save when I did it in rhino.

cnczone didnt let me upload the file because its 1meg so I compressed it.

owen

Thanks Owen, much better, that will teach you to be nice :)

Hey Owen, you gotta laser cutter we can borrow :D

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

you gonna make it out of metal or...?

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.

o.

It's thin Owen, .025 should not be a problem at all. Just went to your site, will go back and check it out further, you are quite the talent Owen ;)

Ken

LOL thats what I was thinking, he is going to post it up one bone at a time as a joke :D

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

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.

Yes, we all deeply sympathize with you Owen :D

Glue / tape seems like the only way to go with these parts. Any other way and you'll get a nice burr at the end of the cutter path, along with a side dish of chatter marks all around.

You should make the frog out of thin plexi, polish it...now that would look cool. The skeletal ice frog :D

not that it'd be much fun to go through the whole process but I wonder if it would work to embed the brass sheet in parafin, and then mill the parafin block.

LOL,

Actually I was giving that some thought, the plexi part :D

Glue seems the simpilist.

Owen the wax is an interesting soultion that I will try to remember.

What is the secret to bending plexiglass without breaking it?
