Wow! Stephen, Fantastic!  I agree with Mark this looks like a "Pain in Uranus"  I wouldn't know where to begin! Great job!

Ha Ha , TTT diameter is 108mm. Ideally 115mm to fit the trapped T at the centre. Stock cutting at 18.5 degrees gives no gaps on the outside Getting the 2 layers to fit snug with rubberbands and Microwave is the way to go. Inner and outer layers are mirrored. Took me 6 hours to seperate the 10 pieces of STC design 72 to 12 dissimilar pieces, only 1 pair has a loose fit, working on it, Also theres another 4 TTT designs with different internals to work on

All thanks to Sir Mark for his tips and diagrams, hes terific help.Otherwise this wouldn't have happen
Nestled set has 4 layers

Holy crap, OCD big time!!!!!!!!!!!!Fantastic stuff Stephen

Hi Stephen, very very nice!!!!   

I'll leave the round and skew stuff alone for now.  I'm too square!

[Robert Yarger]

I'm doing "round stuff" right now, but I am a "round stuff" virgin.  Any pointers?  Strange how calculations used for square items don't come even close to applying to round. 

I had a similar situation with length calculations when applied to the angles of octagon frames.  Strangely, the length of eight equal pieces of wood assembled into a frame changes the degree of miter cut slightly.  Still have not figured that one out yet.  REgardless of the size of a square frame, the degree is always 45.  When it comes to octagon, it should always be 22.5 but that does not seem to be the case.

Buy a lathe, and a helmet . John and I will teach you how to turn moving pieces.

Can be done,but its a learning curve,,,,,,Duck!

[Robert Yarger]

So a lathe is a machine that fights back.  I'm impressed.  Maybe I should not make fun of you guys so much.  Like me, you take your lives into your own hands with every project.

Here tis, the Final Trilogy, from Mark and I
 
'McChin ' is HERE! World's first  180 piece 3 tier split dissected T

Each half opens as 3 pairs, centre, left and right, and the pairs are locked ie not fall apart until you slide them off. 12 dissimilar pieces of 4 to 6 units

Down side is removing 360 pieces of sticky tapes. Up side is there are no gaps on the outter shell, and all pieces slides smooth. Prototype is a Wopping 150mm size, pieces are 12 mm thick,,,,Enjoy

Wow, what an accompishment!!   Way to go Stephen, I doubt anyone will ever top that!!!

[Robert Yarger]

Astonishingly amazing!!!  You guys are genius nutballs.  Still, it looks like you have a small amount of room in the middle to add antoher layer.   

When will we see these in commercial production??

[Mark McCallum]

Great job Stephen!  Way to stick to it and not give up! You give way too much credit to me.  It was all your doing. Congratulations!  It is not only a testament to your woodworking skill, but also your patience! 180 pieces!! WOW!!  Truly an amazing accomplishment.

On page 126 of PWPD (under the picture of a Split Star), Stewart Coffin wrote, "Perhaps someone will now be encouraged to try a three tiered design."  We now know that someone is Stephen Chin.

So you said you'll have 100 of those ready as your exchange puzzle next year?   

[Johan Heyns]

Stephen,

I take my hat off to you!!  Seriously, however you did it, it is YOUR accomplishment.

Great work!!!!!

[Robert Yarger]

OK Stephen,  I said that I don't trade puzzles, but let's talk.  If one of these ever makes it to the library, I call first dibbs.
