Thanks guys for the very kind words. Today I am going to put one of the MK XIII's together as a test prototype. Just to see how it all fits together. There is a lot of work to cleaning up the molded body but that is OK. It is still better than building them from scratch. I will post some pics later today when I get it assembled.

Torpedos

Today was the big day. I put all the pieces together to make a prototype Mark XIII. I wanted to see how everything fit together and check the weight. I also tallied up the hours spent on this torpedo so far.

Weight = 18 grams
Time spent = 105 hours

I started working on the torpedos on the 22nd of last month. It has been a long road, but I think it was worth the effort.

105 hours at $30 per hour makes that a $3150 torp!

It really does look fantastic!

I was surprised that I had that many hours into it but a lot of the time was spent changing directions and doing things over again. Two steps forward and one step back..

John- Holy cow!!!! The torps came out great, and the weight savings should make a difference in the end. I have to tell you, you have taken the detail beyond me.

Time well spent I might add.

Gravman, how do you achieve a wall thickness on a hollow core cast? Do you just roll the casting around to try to evenly coat the inside of the form?

I seem to be overly inquisitive today, and I've already learned something today so if you don't reply till tomorrow, I'll be covered for then too.

That is how I do it. I just close the mold up and roll it over and around and end over end and any other combination I can think of. I have fast setting resin so it does not take too long to flash off.

Thanks Rich but your work on models will always be the greatest. You are the man.

K, seems like I had some cost overruns huh.....

Super job! Also thanks for the tutorial on casting parts; I now want to give that a try. That is if I can steal some of my kid's Legos!

I've been silently following along... and soaking up the knowledge and experience. I hope someday to play with casting. Thanks for the details and nice job!

I always have to use a converter as I have no concept how heavy grams equate to. So for myself and others, 589 grams which you have saved so far comes out to 20.7 ounces or 1 pound 4.7 ounces.

You know I never think in lbs or oz's anymore. When my plant was still open we used grams and kilo's for all measurement in the mixing dept. Thank you for doing the convert for me. .

Thanks guys for all the nice comments on the MK XIII. I am glad you like what I have built.
