SD70Ace

SD70Ace

Postby Rob M » Tue Feb 05, 2013 3:44 pm

Since I'm pretty confident my trucks are going to work I need something other than a Lionel or HP E7 to put them under. And, I've always wanted a TT scale SD70Ace. So far the general plan is to make one master and then resin cast copies. It will have to be in separate components, the main body, cab, the wing, the center top section, etc…

So the question is, if I'm able to pull this off is anyone interested in doing the resin casting?

This is somewhat of a rough draft to see how the doors, roof fans and side vents would look. Everything else should be no problem though the cab might be a little tricky. That is a Kato N scale SD70Ace for comparison.

quite a big fan of the SD70 myself, but isnt that a huge quantum leap from were we are now in the scale? would be nice though.

I had planned on learning how to cast when time came for my U30B shell. Until then, I'll volunteer if absolutely necessary but I suggest someone else handle it.

And yes, I'll buy several.

Yep, and I think think this approach may be a good way to go. Shapeways is cool but the price is a little high and the quality isnt there. For the price of one of their boxcars (or what ever) you can buy a lot of casting supplies.

One of the reasons I bought my cnc router and started posting here was to try and increase available models in the scale. Not so much by manufactuering but by helping others to manufactuer stuff. Basically, I can make some pretty nice things but not a lot of them. Making resin copies would be cheaper and faster.

i agree. the scale is a little too stuck in the pre 60s mode.

Sometimes ago Norkin promised to produce GE Dash 8-40CW (etched brass kit), but I do not know how this project goes.
Competitor? :smile:

P.S. If you want to produce modern locomotive, and want to get more customers, look at the GE C36-7 or GE C30-7.
Some of these locomotives were exported to Estonia in early 2000s, so maybe some Estonian or Russian modellers would like to purchase such model...

P.P.S. As for me, it's TOO modern locomotive...
Personally I prefer 1950s, but even if you need locomotive of post-60s era... If I am not mistaken, it is suitable only for the 2000s.
For example, it will not be compatible with your G31 gondolas, because most of them were scrapped in 1990s.

there are some freight cars out there that would look great behind an sd 70. my choice would be a string of conducters tank cars using a three bay covered hopper as the buffer car.
