Hi folks,

I am new as a member to the site, but have been working on some puzzle mods for several months. I have recently completed two prototypes, one of which is alarmingly similar to the Thomas cube posted recently (but I saw this for the fisrt time two days ago, honest!). I enclose a few pictures.

The puzzles are cast in resin from silicon moulds, and I am finding it tremendously difficult to make accurate masters for the moulds. I am also having some problems with sticker bubbling (they are a good quality vinyl).

And comments or suggestions?

Wow! The first one is very, very similar to the mod I was planning next! Actually, it's exactly the same. :-)

Nice one.

I also like the second one. Could you post some more pictures?

Thomas

For a first post, that is simply amazing. Welcome to the forum! 8-)

Those variations are really neat, and they demonstrate that sometimes geniuses think alike. Right Thomas?

:)

Huh, I can't fathom how to buildup Skewbs so cleverly!

For people who don't see the resemblance between my Thomas' Cube and Timselkirk's first mod, I put them next to each other. The difference is that mine has straight lines on each side. And that's why some of my triangle pieces overlap a bit on the adjacent side. The core of Timselkirk's design is rotated slightly different inside the cube.
As I said, I had noticed this possibility a while ago, and I was about to start building it next weekend. I'm Glad I didn't start already. Now I can focus on other ideas. :-)

Thomas,

Thanks for the side by side pics. I couldn't believe it when I saw your first pics, for a few seconds I thought that they were exactly the same! To have two such similar ideas deleloped at the same time is quite a coincidence.

I think your cube is executed somewhat more neatly than mine. Have you used the same production method? Eurethane resin in silicone moulds? I am having difficulty getting my masters exactly right. Any suggestions?

I will try to get a few more pics in the next day or two; I don't get much time for building/ posting, maybe 15-20 minutes average a day, so things happen very slowly!

Everyone,
I was going to call the first mod a skew2b with the 2 in superscript, as it is effectively a skewed skewb (or Thomas cube rotated slightly around the longest axis). The second mod is half normal skewb (expanded a bit) and half skew2b, so I was going to call it the HalfandHalfSkewb. Neither name is particularly snappy. Any better suggestions?

Yes,

I was unsure about the colours; it does look better in real life: white, silver and a kind of pewter colour. I thought a kind of "black and white" cube would make it stand out a bit!

I used plastic sheet for the outside. I should have used plastic sheet as well for the insides, but I used Apoxie Sculpt instead. That works fine but needs a lot of sanding and it makes the puzzle kind of heavy. For a next puzzle I'll try to use plastic sheet only.

How did you came up with this idea? I realised it could be done while I was building my second Skewb mod. That one was thought off when I built my first Skewb mod. And that one was a natural progression from my cubic Megaminx.

Thomas,

When I first got interested in skewb mods about 6 months ago, I realised its was taking ages to do the trig to work out piece sizes, so I wrote a little program in Delphi to simulate a skewb that allowed me to mess around with possible internal rotations, and this is the nicest I have found so far that is different to anything anyone else had done.

I also use apoxie sculpt, but for the masters that I use to cast the silicone moulds. Your final pieces look excellent. Have you tried making moulds from them?

I used a (truncated) Skewb Ultimate for my Thomas' Cube, which, as I said, I extended with plastic sheet. I may build a few more of these puzzles. Maybe using molds. I guess it's easier then to make masters for a regular Skewb. That way I don't have to truncate first (and they are more readily available). But then again, perhaps I should just stick to plastic sheet. I know Tony Fisher often uses molds, but prefers plastic sheet.

Your Delphi program sounds interesting. It is indeed something that I'm sometimes missing.

Thomas

There is a time for using plastic sheet and there is a time for using moulds. The trick is deciding which is better for a particular job.
Sticker bubbling may be the result of not allowing resin to fully cure. Although hard quite quickly I believe it may take several days or even weeks before some resins have completely cured. Since I am new to using polyurethane resins this is only a theory.

How come people are taking old mechanisms and slapping on more material until it's a cube with weird slicings and then call them new puzzles? Come on! :roll:

Just kidding. Ate least you're doing something interesting instead of posting ungoodly grammered content on here. :wink:

As promised, here are some more pics of the 2nd mod. I have included some of the puzzles semi-assembled so that you can see the half which is a skew2b and the half which is a normal skewb (enlarged) being added.
