All necessary pieces are cut now…..allocation and dimensions are marked on masking tape. One day this pile of blocks will turn into a sub.
Why I cut them all?….well to get the max out of the modeling board with the min amount of waste.
I made a scheme with the dimensions needed and calculated how they will best fit in the modeling boards I had.
Stern moulds.
As you will know I like doing things complicated and like designing stuff. Here again I calculated what is the most economic thing to do (as this is not my occupation I don’t give a darn what amount of time I spent doing it):
- Make the moulds just by pouring a vast amount of silicone into a box or
- Make the moulds by shaping some modeling board and use a thin jacked of silicone to take the shape of the stern master.
Did it turn out ok? well it was a hell of work, it was challenging, precision was the key. I had to make dowel pins and pockets so the multiple pieces that forms the Articulated mould will fit perfectly together. The master is plain so I needed a caliber to make things hollow. The master is not provided with an index to take the hull parts I had to take that in the design too. But I think It turned out ok. Will it work? I don’t know, I will see in a later stage if it works , if it does not…..we had fun anyway.
Dowel pins and pockets (clearance between them is 0.02 mm) I think I made close to 50 pc of them know....and counting
Caliber mould, with integrated dummy index lips
Caliber mould end plate, after casting it will become one with the caliber and fitted on the mould masters to make the cast of the part hollow.
The articulated caliber mould in different stages of assembly
Mould master base plate, the silicone sleeve inside need to be casted in both mould master halves, so I needed a base plate to do it.

Thats it for now,
