I am making caboose steps today, it will put your eyes out after a while! On the hand, I have discovered that the cabooses don't look right without steps.

That task screams out to be patterned and molded Malcolm. Kudu's to your unfailing endurance of the tedium nevertheless.

Good gravy you are a patient man indeed.

Indeed!
I have considered casting but I was afraid these would be to thin and fragile to hold up. The styrene will "give" a little if is bumped or mishandled. Is there a resin that provides a more flexible casting?
Malcolm
Not so resin is some what stronger a times. I have parts that i have cast at .015" thick that are very durable.

Marty,
If you don't mind, what brand of resin are you casting with?
Thanks, malcolm
I use a resin called Roto One it is an AB mix in 1 qt size.
It has a pour rate of about 3 minutes and a cure time of about 35-40 minutes.
I purchase it from Golden West ask for cliff
It is about 39.00 per 1 qt set AB mix.
this resin has given good results over the past 8 years.

There are several options available in resin rnagine from relatively short working time (3 min) to some that give you 20 min of working time. Most will exceed your needs and requirements of stability.
I generally use one from Freeman with a 6 min working time; demold on small part is 20-30 min. Full 100% cure is longer.
And yes, you can cast thin sections.
Please post photos of your casting efforts, specifically, small items with thin walls.
Thanks.
