 Post subject: My Trajber's Octahedron (updated)

About last week I asked a random kid at school for his Rubik's Cube and surprisingly he said I could have it. So I've spent the last week or so trying to build a Trajber's Octahedron.

It is actually very difficult to get all the sides sanded down the same amount. Anyone know a way to get it perfect?

Since today is Thanks Giving here I'm going to take a break from it but I expect it to be done by Sunday.

Not too bad. IMO it's looks like a hard puzzle to make. The corners are half-truncated-cube corners but the centers and edges look hard.

It looks like you truncated a little further than the conventional Trajber's Octahedron.

Good luck!!

I visited Josef Trajber in December 2006. He is a very kind person.
He had only one copy of his own invention left.
He wanted to give it to me, but I refused. :-)

Have fun,

Ron

Sorry about the delay on building it. I have been working on a paper cube. (see pictures) It has taken me a long time and I still have a couple cubies still not finished. I took a break for a while after working on that also.

It took me a while to fill in all the cracks and even then I still had some imperfections. I spent last night and this morning spray painting it.

I found that duct taping a small amount of sand paper to a plastic glove is really effective when having to sand small tight areas.

Anyone know how to make odd shaped stickers easily?

Don't overlook the convenience (luxury) of a sanding sponge, like the one in this picture from Harbor Freight. The angled ones fit nicely into cracks for fine sanding, as shown here.

I don't know if Harbor Freight's sanding sponges are any good, but they're certainly cheap. But 3M's sanding sponges are good enough to be washed and re-used many times.

Heres the puzzle partly stickered. I only had 6 colors. I ordered cyan and pink vinyl sheets from cubesmith.com about an hour or so ago.

Its a confusing solve!

PS. How much do you think this would go for on the market?

PPS. The yellowish thing on the green stickers on solved is a reflection of a lamp.

Not to bad, but I think that you should get out these sticker, make new one with a rules and scizor, make it perfect and same size. It'll look great.

One problem with the stickers I had was that the pieces were actually a different size. Like the face of one edge was 2 cm while another was 3.

The stickers seem to cost too much for me to scrap them though..
