Thought I would share my new Wood RR Crossing fresh from the molds. This is cast in resin and has super detail with wood grain and bolt heads. I decided resin was the way to go, I see how the wood on the old cars and structures starts to separate/warp with time/temp change. I would hate to have the wood warp and take out a brass loco!

Never said it wouldn't warp, but resin is hardly the end-all answer.

I've seen lots of 'high quality' resin castings warp over time. Heck, I've seen brand new castings from people within your industry that were already warped out of the box, from companies like Backwoods Miniatures. among others.

Besides, in my case, I have no other option as I'm laying down grade crossings that each need a custom shape. So if you're willing to hand-make one for each crossing I have, I'm all ears.

We all have our own opinions on what works best. I too have seen warped up junk castings, then i have also seen excellent castings. 99% of the time the bad ones are due to bad storage, adding fillers to the resin, and the biggest thing they demold while still soft leaving it warped from the get go. The other thing they make different type and quality resins. Many just buy the cheapest they can find and not the best for what they are using it for. I've poured resin for many years, my original casting are still as nice and flat as the day i poured them. Just because you've bought something that was bad casting doesnt mean they all are. I'm sure you have had a bad hamburger once in your life, so you will never buy another and that means all hamburgers are bad??? The bottom line is i never even offered it for sale here, just  simply showing whats coming out. The beauty of model railroading is you can build how you want with your own ideas. You choose to use wood and thats great, i choose resin, which is best? There is plenty of opinions on that, but at least now there is an option in the market.

And BTW yes i can make custom sizes much easier and faster than you can with strip wood on my 63"x 36" laser. Again its having the right tool and material for the job. Have a great day!

Truth.
...if you use a high quality resin and are not in a hurry to demold resin has no warping issues.

Quality resin - just what do you use? 

 

If it's a flat mold putting the casting on a section of plate glass to fully cure is very useful.
