DD-793 update

Hi All;

Here is the development of the five inch turret, just the build. It is now in place, rotates and elevates. Why do that? It makes the model more pose able for photography, and like the mountain, it was there. It takes about a week to make one. Only four more to go.

Regards, rjccjr

DD-793 update

Hi;

Just a quick update DD-793 now has all five elevatable and rotatable turrets. Now I'm dealing with rotation tables for the quad forties. That will take a while. The smaller weapons will not get the same treatment. It is almost ready for the mast work.

DD-793 update

Hi All;

One element, while involved in this undertaking, is the fact that no matter how carefully you work, it always pays to build what you design. That way you discover what works and what doesn't. For example, the original design of the rotator tables for the turrets did work, but the center pin was weak and easily gave way under handling. So design number two was tried. In that case, the center pin was much stronger, but the bottom ring was too narrow and difficult to glue. If the glue was applied to the outside of the rings, everything held together and the assembly worked, but if the glue was attached directly to the ring, it froze the pin. The third attempt is workable and can be glued either way. Actually they all work, but if you aren't awfully careful, frustration comes too easily. Here is a photo which includes all three versions. Careful perusal will show you why the third option is the better choice.

DD-793 update

Hi All;

The first quad 40MM assembly finally came together. The entire unit is less the an inch wide. There are twenty eight pieces in it right now and about a dozen more to go. The unit rotates very nicely, but it is beyond my ability to make it elevate. It is simply too small to attempt. DD-850 is set beside DD-793 so you can see the difference in the size of the turrets in the same scale. It seems that no matter how well the plan goes, I always wind up redrawing the major assemblies as they go along. It is very rewarding when something goes right.

Regards, rjccjr

DD-793 update

Hi;

Worked on quad 40 MM this week. Starboard side of mount has some detail. Looks like there will be fifty one pieces per mount. Spent half the week redrawing the twin mount aft. You might think that the twin would be easier, just a half of the quad. Not so. It is a very different set up, but the good side is that there is only one to do. Of course these patterns are common to many ships. Theoretically they will be available for other versions and other ship designs, if I ever finish this one.

Regards rjccjr
