Hey Bill,

Congrats on the great article in RMC. Going to have to give Sculptamold Mix a try.

Rich, I haven't tried that, but my sense is it wouldn't work very well. If the Sculptamold is mostly set up the crunched foil won't make much of an impression in it, at least nothing that looks like a rock cut. And if the Sculptamold is still very soft (think really thick oatmeal) the foil will stick to it and the Sculptamold will tend to self level a bit after the foil is pulled away.

I have seen crunched up aluminum foil spread out like a very wrinkled up sheet and plaster poured into it to make large rock wall castings.

Do you want to create a blasted hard rockface look or more natural looking rock?
Pennman Posted - 11/19/2020 : 11:50:32 AM

When the sculptamold is still in the workable form, would it help to use a ball of crunched aluminum foil pressed against the bank to form imperfections rather than using a mold or tools

Bill Gill Posted - 11/18/2020 : 8:23:33 PM
Bernd, What I like about using Sculptamold is I can fit it to exactly where I want without fitting lots of separate plaster castings onto a given area. Also, the results are one of a kind.
I've watched videos of modelers plopping on globs of plaster and then carving/chipping it before it fully cures to make rock faces. That looks good. I'm not sure if all the shaping I did with tools for that rock cut was any faster, but it's easier to fix goofs and there was sure a lot less to clean up after.

A red tinge can be blamed on chemical weathering leaching iron oxides :-) :-)

Bill Gill Posted - 11/18/2020 : 4:29:32 PM
Thanks everybody for the comments and conjectures. You are right, my photo does have a slight greenish cast to the rock face that I didn't notice. That's probably reflections of greenery outside the window. The prototype isn't serpentine, although some of the photos you have posted do look very similar.

Here's another look with some of the green removed. It's still not exactly right. The color along the left side of the photo is closer, though maybe just a twinge too red there now.

Bernd Posted - 11/18/2020 : 12:40:23 PM
Nice work on that rock face Bill. I did some rubber mold castings just for fun. Now I'll have to try the Bill Gill method of rock formations.

deemery Posted - 11/18/2020 : 10:14:19 AM
Yeah, Bill's photo does have that green tinge to it.

We visited a serpentine quarry on a field trip to Vermont 2 years ago (back when we could still do -field trips-...)

Michael Hohn Posted - 11/18/2020 : 10:00:40 AM
From the greenish color it might be a serpentinite. Very light color, though. More research is needed.
deemery Posted - 11/18/2020 : 09:34:18 AM
One of my geology profs is an expert on metamorphic rocks of Vermont. She'd probably identify that as a metamorphic gneiss. https://pubs.usgs.gov/sim/3184/ Very gneiss, indeed! :-)

Bill Gill Posted - 11/18/2020 : 08:31:00 AM
Here's a shot of a rock cut that didn't make the cut for the magazine article. This is the summit point of the layout.

Thought it was worth showing that Sculptamold can be used for modeling other than smooth, glacially weathered rock.

The Sculptamold mix was precolored the dark gray and the lighter intrusions were brush painted after it dried. The mix was pretty stiff and the jagged, blasted rock faces were shaped with a rigid, narrow, pointed chemistry spatula and small palette knives while the mix was still wet. It wasn't 'carved' into a dried coating.
It needs more shrubs, weeds and dead leaves, and since this side of the layout is ambiguously somewhere between late Fall to early Spring, maybe even some icicles in the deep shadowy areas.

It's supposed to be some kind of metamorphic rock I've seen when driving around parts of New England. (Any guesses Mike Hohn?)

Thank you, Rich & Ted!

Congratulations on the article.

Bill Gill Posted - 11/02/2020 : 07:30:49 AM
Thanks Thanx Thom (still have to contact you).

Yes Congrats on the article! You-Da-Man! Thanx Thom...
