Greetings SBG,
I made a 3D model of a tsukamaki dai including all the dimensions. The original plan drawings were made by Thomas L. Buck and can be found on his website tsukamaki.net. The drawings only listed a couple of basic dimensions so I went ahead and added all of the missing ones according to what I felt would be comfortable for me, this can be changed as you see fit.
The bar stock I used in place of a nakago is from 1/4" steel bar stock and should be tapered toward the end both in width and in thickness so it easily yet firmly fits inside the tsuka your working on. This nakago can be switched out for ones of different sizes and shapes and is attached to the wooden bar with two wing nuts (which I couldn't draw for this model)
The other end of the wooden bar freely sits in between the small retaining blocks to allow for movement up and down and side to side while also being able to flip around so you can work on both sides of the tsuka easily. The pressure of your hands on the tsuka will keep it locked in. I prefer the bar to be at a slight angle but you can adjust the dimensions of the stand so that it lays flat with no angle. There is also a hole drilled in the nakago so it can be secured to the tsuka with a mekugi.
The wood I chose was 3/4" maple veneer with a plywood core, this way it will be very strong and resist warping or cracking while also being able to be stained and finished nicely if I choose. You can choose whatever wood you like best. Let me know if I've missed anything and I'll try to add it asap.
Thanks for looking
