I am trying to build a second Mastermorphix. I am using the tips from a Magic Triangle. I need some expert advice on how might be the best way to attach the tips to the cube corners. I see at least three options: 1. Some kind of glue - what kind? I don't know a glue that is strong enough. 2. Weld it like Ton does with Square-1 mods. I don't know if the Magic Triangle plastic can be welded. and 3. Epoxy putty like Milliput. Milliput will make it heavy. Maybe there is a 4th option: fill the space with some kind of resin. What kind of resin will bond? I need some advice. Here is a photo so you can see the seam I am trying to make.

In this case I would use a little bit of putty, test fit it , let it dry a bit and glue it with super glue

But I gues the glue than Duan Cash uses might be perfect

The melding is not to replace glue , just to full caps, also in this case this might be usefull

If you go with the reson idea, drill some holes into the corner cube and the inside cavity of the triangle cap. The resin will harden and act as a plug, holding the pieces together.

Milliput is great for get the surfaces smooth.

Here was my method:

Image

Instead of cutting the triangle tip I cut the corner piece instead. By using a "genuine" cube I retained the little cap that fits over the hollow part of the cube so I secured that down with superglue so it would make for one "solid" corner piece to work with.

Next I made sure that the two pieces of the triangle were fit together nice and snug before joining the triangle parts to each other with superglue. I found that the triangle parts can be slightly misaligned or not properly joined together, hence the extra care.

I found that shaping the corner piece to fit up against the triangle piece required less messy work than cutting the triangle piece to accept a whole corner piece. (this last sentence edited for clarity)

After shaping the corner piece it forms a "cup" which I completely filled with a 2 part epoxy (clear, 4-6 minute set, 1000psi). It's not as strong as the 3500 psi stuff that Duane works with but seriously, with so much surface area involved that's being joined I found very little need to look for something more exotic. A tiny bit of "overflow" will usually ooze out of the "cup" when it's joined to the triangle (make sure it's held upright for 5-10 minutes) but that overflow helps fill in cracks and help with the bond. Plus it's easy to scrape off any excess after about 20 minutes with a blade when it's still soft but not sticky.


I also found that if two epoxied pieces ever did come apart, rather than trying to epoxy again I used a little superglue. I'm not sure what it is, but superglue on a dry epoxy surface sets almost instantaneously (we're talking 1/4 a second or less) and forms an extremely strong bond between the epoxy and the puzzle plastic.

I COULD use a 2500 psi 2 part epoxy that I have that sets in 30 minutes, but there's no need to take that much more Time for a strong bond.

For all of you who are making a mastermorphyx puzzle, I would love to see some work in progress pictures and pictures of the individual pieces. Do you start with basically a half truncated cube and build it up from there? I have one old picture from Carter that I think is posted on her site. This is one of the next customs that I would like to work on.

Thanks for the great responses! I might need to test all these ideas. Dodd, I will post photos soon.

I second Dodd. This is a puzzle I'm very interested in building, and any ideas would be extremely helpful.
