Resin would be the way to go, BUT, You could not use the master pictured. The biggest issue would be the number board area. I'm assuming its hollow, and as such, would create a huge undercut area in the mould. The silicone used for moulds can flex, but it cannot move that much. The solution would be to either make the number board area thicker (more solid), or have it as a seperate piece. When a silicone mould is made, it picks up ALL of the surface details, good and bad. I made a mould once of something that had been decaled, and every cast that I made had the shadow of the decals visable. So, the cab surfaces need to be smooth and blemish free. Also, the smoother the surfaces, the longer the mould will last. I'm going to be splitting the model into probably at least 3 pieces to use for the master. Did the fine details like the numberboards and grab holes make it through the printing process? Will you be able to show us a primered version to better show the finish? At this point, it's not really worth going that far with the test prints, in my opinion. The resin versions will be much better. If most of the cab is a standard EMD cab with modifications, why not just make the modified part of the cab and use a Cannon cab for the rest? The locomotive's nose is a whole new piece, and the cab is a substantially different shape. Nice thought though, it'd be nice!

Sounds like your really putting thought into it and look forward to seeing your progress. If you need any more assistance please shout out, Im eager to model one or two of these so would be happy to lead a and developing it where I can.

If you need a hand with the moulding/casting, let me know. I do quite a bit of casting.

Have there been any updates to this project yet? Any thought of a SD60E cab?

I have the parts redesigned for resin casting all but the cab, which will be done hopefully this week. We are planning on ordering the masters and having casting start sometime around February.

I am looking forward to updates as well. This is an interesting project you took upon yourself and I am very happy to see you are sticking with it, working out the bugs and tryng to bring us a new part. I look forward to seeing the final results and possibly purchasing a few from you.

Now if someone would do the SD60E!!!! I tried, but failed miserably due to lack of dimensions. Working and guesstimates from photos DO NOT make a good model!!!

We've talked about the SD60E, but like you, I'm really worried about trying it without dimensions. The Admiral cab is straightforward since it can be taken from a standard EMD cab, but that other one is a different story.

This topic has somehow stayed on the "new topics" page for weeks. It's a good bet that its a very popular idea with us based on that. No matter what, it's a very safe bet that what ever you produce will be far better than anything I can make from scratch. I'm pretty excited about it.

We need someone who is a modeler and works for NS to help us get dimensions of that SD60E cab. I know of either one or the other. And unfortunately, the ones I know that work for NS don't have the luxury to pick and choose what equipment is assigned to their trains!!

Has anyone tried emailing the company that fabricates the SD60E cabs? Doesn't hurt to try.

Popping here for a quick update, things are basically ready to roll, once we get some funding figured out on our end for the resin masters. Not using Shapeways is a bit more expensive, as it turns out. I've also gone ahead and modified the cab windows to be a later production cab rather than the early version as it had originally been. Seeing as this style will continue to be used on further rebuilds, this seemed like the right course of action, and didn't justify doubling the cost of the masters to produce both versions. I hope this doesn't keep anyone up at night...
An interesting tidbit I learned recently from the manufacturer that produces the "frosted ultra detail" material for Shapeways: After a few years the material will disintigrate... So, I think resin is the right call.
I'm not completely sure yet what these will cost per cab, but I will be posting hopefully soon with details on them. The kits will include a resin cab, a resin nose/battery boxes, a resin numberboard housing, and two resin stepwell guards. To complete the model, you'll need a Cannon window set(avoiding the need to use a particular manufacturer's SD40-2), a Detail Associates sand filler and light housing, a handful of 18" drop grabs (use your favorite), and either some small pieces of sheet styrene or etched brass steps/walkway tread if you so desire.

Also sounds good to me. Any idea when you may get them to market?? Tease us with a photo of the master??
On a related note, there was a rumor for a Cresent cab a few weeks ago on a thread I was following on Facebook.....seems to have died a quiet death, too bad though, as the conversions the builder did of SD60E's was fantastic.
