1/72 CLB-75 Resin Model Kit
Posted by CodyJ on Friday, August 14, 2015 6:43 PM

I want it to be clear I am not advertising. 

Just wanted to show you a kit that I made.  It was designed on the computer in a CAD 3D program.  I then had it 3D printed and made the instructions.  Its in 1/72 scale and I am very happy with the result.

I take it that must be a British tank.  Never seen nor heard of it before!

Its actually American.  It was made in hopes to sell to the American Army.  However the sale of it fell through after seeing the MKIV the British were using so effectivly.  Lost to time other than the half-dozen pictures that remain as proof to its existance.  

"The C. L. Best Tractor Company of San Leandro, California built two mock-up types on their CLB 75 tractor. One had a semi-cylindrical hull with a turret and the other was similar but the hull had flat surfaces. These two machines appeared at a Fourth of July celebration in San Francisco in 1917, in manoeuvres with units of the California National Guard."

I'm curious about something.  In order to cast in resin, you had to have a pattern.  I assume the 3D printing was to produce the pattern.  Why not stop there, and build the model from the 3D printed parts?  Or was the problem the tiny steps in the 3D printed object, which could be sanded to make a smoother cast object?

Good question Don.  The reason is, after a mold wears out then you need to recast the master again.  If you only cast a resin copy you lose detail that the first mold may have missed.  So in short, when a new mold is needed, the master from the 3D printer is the most accurate to start with.

That being said I will make one of the Resin cast ones here soon.  I would like to have a "Build" pic to accompany the rest.

Looks quite good !

Out of curiosity, do you know the effective printing resolution of the 3D printer that was used to print the CAD solid model?

WOW !

 I just saw a program about a Sub that was built in the 1800s and actually worked .Now the model you have .Cut in half lengthwise and re-assembled and then cut horizontally with a square sided flat bottom could become the sub .

 A smaller turret assembly would work in place of what's there .  T.B.

I'm assuming you're not talking abouit the C.S.S. Hunley but the one they used after the Civil War to harvest oysters for pearls.  It's only a matter oy yards of the Panama shoreline and can be seen sticking ouit of the water.

There was a show on that one a few weeks ago where they did some exploratory work on her to find out more about her.
