“I wouldn't dare guess a price yet.“
Seeing as I only need enough 1/2 frames to make up 3 flatcars total we might need to discuss price unless you plan on doing the design work and marketing the finished product yourself which is fine by me. The only F-22 I’ve ever seen in O Scale was done by RY Models in brass with factory paint and they fetch anywhere from $300-$450 a car. So an inexpensive kit should sell well.

I looked up “visible 3D layering” and that could be an issue if primer that can be sanded won’t cover it up. Just for fun I looked up articles on how to reduce visible layering and thought my head would explode with layering height, nozzle diameter, printing speed, and so on! :shock:

I had a chance to screw around with this F-22 for a few after work....just a test but its scaled from the PRR F-22 drawings I found online. Still would need to add a bolster, an accurate place to mount a Kadee Box, and all the rivets, stake pockets,etc. I was just curious how much a half would cost.

They can print it in full as well. This would save you some of the handling charges involved too.

I'm far from done but I imagine the price wont go up too much more when I add the details. I'll need the dimensions for the Kadee boxes you're going to use and trucks. I'd rather just make the coupler box in the model ( as it should be).. and make it so you can mount a Kadee # (whatever) in there. I'll let you add cut lever, train lines, vertical brake wheel and appliances since that stuff is available elsewhere and way more durable. If you have grabs you want to use, I can create the holes with NBC's and you can apply them. When its finished, I recommend you buy one to make sure everything is how you want it. The finish will need to be finely sanded and primed but should look good, definitely if you weather it. Maybe sneak some weights in there too because this thing will weigh damn near nothing. The big thing to remember here is that I don't have a lot of accurate information on this car but it will be a a good representation of the prototype.

Like I said, I didn't plan on charging you but maybe we can trade something in the future. Soon I'll finally have a work shop once again as I've since divorced, tore down my layout and moved south back to my hometown of Kalamazoo. This is kinda how I get my modeling "Fix" On the side, Im drawing up a Conrail B30-7R for a future 1:48 build as well.

Awesome, Patrick! I’ll get you Kadee and truck dimensions tomorrow! We can work on some kind of trade if you prefer that also!

Been slammed at work. I still need to play around with the flat. Hopefully in the next few days I can get back on it.

john I don't have any trucks around right now to measure, can you tell me what the measurement from top of rail to top of the truck bolster cup is?

I’m coming up with 5/8” from top of rail to the bottom of bolster cup facing rail. But not every truck set is going to be the same. If you make the bolster cup that attaches to the center beam a 1/4” thick that should cover those that need to add a washer or two or do some minor filing to get the correct height.

Patrick, just checking to see if you’ve had a chance to make any progress on the F22.
