The Ship Model Forum

I work in a lab that tests construction materials and soil samples for construction projects. My wife thought I was crazy when I told her I was washing dirt and cooking it in an oven at work!

[quote="ArizonaBB39"]Waiting for samples to dry? Sounds like we might have a similar line of work![/quote]

I don't know what you do, but I am an environmental engineer specializing in fluvial geomorphology. I am also going back to school late in life for a PhD. The samples are bed material samples from the creeks and rivers I am studying, mostly sand and clay/silt.

What do you do?

A couple of things have really put a damper on my progress on Bennington. The first is that North Star Models is supposed to be releasng a 1/350 US Navy 3D Figure Set, and I want to wait to see them before I put any more figures on. The second, more important, reason is that I have been spending quite a bit of time in the lab waiting for sediment samples to dry and bake. The good news about that though is that I found another project that I am working on to kill the time while I wait.[/quote]

OMG!!!

The monster is bigger than we thought!!!

Next thing you know he'll get free access to an SLA and begin producing masters for resin casting!!
And then he'll figure out how to cast in quantity and start producing the after-market parts missed by other manufacturers!!!!

OMG!!!!

[quote="Russ2146"]Yes, it was latent. Just had to draw it out, feed it. :heh: Then let it loose :twisted:

:lol_1:
Too true!

And now the monster has something else to feed on...

To make a long story short, I'm scratch building a 144 scale USS Greenling (SSN-614) for a friend of mine. With a set of plans for USS Permit (SSN-594), a print of the various subs in the class and a photograph of Gato (SSN-SSN-615), I was able to build a virtual model of Greenling in AutoCad.

Another friend of mine has access to a stereolithography (SLA) system and said that he could use it to make the small parts for me. The SLA method uses an ultraviolet laser that solidifies a thin liquid photopolymer resin. After one layer is solidified the SLA elevator platform is lowered 0.05 mm - 0.015 mm (0.002� � 0.006�) and the process is repeated. This continues until the whole part is completed. The advantage of this is that the parts can be generated straight from 3D AutoCad drawings, which I have recently learned to do.

Because my friend said that I needed to limitthe size of the part to about 4", I subdivided the model into 13 parts (3 of which are duplicates). Attached is a file showing the parts, and just for fun, I "painted" the reassembled model.

Another benefit of doing this, is that if I later decide to do the print in 3D, I won't have to knock off anyone else's parts. I can just use my model. :woo_hoo:

I'm going to start a WIP on her and will post the link here when I get it posted if you are interested in the process I followed to get to this point.

CHEERS!!

Hi Again Cyndi,

Here are 4 Essex Class Carriers at Free Time Hobbies.

http://www.freetimehobbies.com/search.aspx?find=essex&category=2746

Hi Cyndi,

To my knowledge, there is NOT a model of Bennington available at any scale.

There are various models of Essex class carriers available, but I think all would take modification of some degree to accurately build CVS-20. There are others on This Forum far more knowledgeable than myself on this matter, so if you don't get a response here, you might try posting on the Main Forum or even the Calling All Carriers Forum. What year(s) was your dad on Bennington? It may make a difference as to what kits are available.

Good Luck!

My dad was on the uss benningtom cvs 20 and wants a model kit to make. Do you know where I can find one.

Thanks
Cyndi Flood

Created? I think that ship sailed,
Brought out maybe.
:big_grin:

OH OH! I've created a monster!!!

but I do have a spare slide rule laying around somewhere (shuffle, shuffle) and when I find it I will send it to you poste haste! :big_grin:

[quote="Christian M."]Russel,

at such Professors you must know that they have a small law:

�1 - I'm right
�2 - I'm always right
�3 - If not, see �1 and �2!

That's the whole story about some Professors! When I wrote my master work for master degree of history I came in dispute with my about theme what was turning point in American War of Independence. I wrote in conclusion a) enter of France into war, b) sending troops to help Washington and c) battle of Cowpens and Guilford House ... my Professore denied this and told Yorktown was with French financial help ans supplies only. I replied that Yorktown was result of Cowpens and Guilford Coruthouse and without French land and sea forces, there had no battle of Yorktown happened. But you know, I got minus point for my conclusion, because small professor law as named above. :heh:
But this is 18 years ago, so hell on it! :smallsmile:[/quote]

:lol_1:
So true!

My wife also had a bad experience with a narrow minded prof during her Masters program in Speech Pathology. One of her prof's didn't like her and flunked her on one of her in-class papers. She protested and they had outside prof's grade all of the papers, and they decided hers was the best one. The prof flunked them all rather than give her the score she deserved. Another larger protest resulted in them all retaking the test.

And Russ, I heard that same thing as an undergrad. I wonder where that puts me? I do both. :smallsmile:

Something I heard long ago in reference to a Mechanical Engineering professor:

Those who can, Do
Those who can't, Teach

He did not. Even worse, when I said that the points didn't matter, that I just wanted to know if significant digits mattered, 2 other students came in and he blew me off. He never did admit it and I lost a lot of respect for him that day.

I used to use a planimeter a lot as a surveyor/draftsman/engineering technician before and part of the time I was going to college. They are really cool devices and you are right they are brilliant and simple. They have two sets of rollers with counters that measure distances (+ and -) in the "x-direction" and "y-direction" and multiply them together. You gotta love the ingenuity of the old school engineers.

Significant digits are taught in high school... do not use more than your input data. And, when you use a slide rule, more that you can slide (figures, but I never used one) but I know how to turn multiplication into addition. I hope he gave you the full score after hearing your argument!

There are many more nice mechanical computers. A [url=http://en.wikipedia.org/wiki/Planimeter]planimeter[/url] gives you the surface of a closed curve and with the right mathematical derivation you can only conclude it's a brilliant device. I tried to emulate it when calculating the curvature of an arbitrary closed curve (found something more easy and quicker to use later). Lots of these are in the science museums and most people just walk past them...

Oh heck no!

I don't think most of the professors do. I got into a debate/argument with one because I used significant digits for an interim calculation on one of his tests a few years back and he had not, so he took a couple of points off because we had different answers (even though we had the same final answer). He was younger than I am, had never used a slide rule, and therefore truly didn't understand the significance of significant digits.

More to the point, do they know how it works? :smallsmile:

Wow Cody! A slide rule? I learned to use one way back when. We've been looking for dad's and the only one we have been able to find is a circular one, which is cool, but I want the real McCoy too. I wonder how many of today's engineering students would even know what it is?

13/64" = 0.203" is real close. Using an Engineer's scale, I measured them at between 10 and 11 on the 50 scale, so they are between 0.2" and 0.22". This would put them between 5'9" and 6'5" tall, which is what they should be. I still think they look kind of squatty. I guess they are just big boned. :big_grin:

So how "tall" are these guys? :thinking: Dusted off my slide rule, put on the reading glasses, and figured they are about 13/64 of an inch. Am I close?

([i]... IF[/i] they are tall sailors!)
