Mickael’s been in touch with his HO scale rock tunnel forms.
“Al,
Here are a few pictures of my rock tunnel entrances, before and after assembly and the natural materials used.
I used tree bark from a white oak tree in the woods that I found and glued them (all 4 pcs.) to the top of the tunnel entrances, let them dry and painted them with a dark gray mixed with white paint and water.
Then dry brushed them with white paint.

Now on to Joseph:
“I have been reading this article for some time now and enjoy it very much. Unlike most on here, I run both O and S scale trains.
I thought I would share so hints I got from the old timers. Since I am 70 maybe I am the old timer now. I use a lot of wheat and rice bulbs with bare wire leads. I found nail polish make a good wire insulation after all connections are made. I also use it to lock on nuts to bolts and numerous other things. I prefer red so I can tell that everything is covered, but clear , black or any color will do.
The other hint is artificial coal. The original artificial coal was made from Bakelite which has some hazard properties. They then went to plastic which also has its draw backs. I found these lodged in motors and cut up belts using coal loaders. I also found black aquarium gravel worked better but still jammed up belts and was work to un-lodge from places. Try Grape Nuts cereal. Dry in microwave for 30 seconds then spray paint black. It takes a few spray times. Now if this gets caught in the motor or belts is crunches up and does not lodge as often as other materials. It takes just a little air and a brush to clean up Also safer for children and pets.
Your comments please….
Joseph”
“Well, seeing as how I am the least handy person on this planet, and cheap to boot, here are a couple:
Since my layout is in a permanent winter mode, I wrapped the plywood bases in white bedsheets —
It makes a a great “canvas” for laying down landscaping and a SUPERB conduit to run the wiring between the sheets and the wood – no drilling required.
The “snow” is actually a ceramic product: Duncan’s no-fire snow, available, among others, online at Amazon. You can paint or sculpt it on, and it dries to a plaster-like state.
More recently I wanted to add some ice-covered ponds, and as I dislike mixing chemicals, etc. for water effects, I went to the nearest drugstore and purchased a couple of ladies’ hand mirrors, you know, the kind they carry in their purses. I laid down some snow and partially buried them, feathering the edges with more snow.
But then I wanted a larger ice-covered swamp or pond, and here comes the cheapest solution of all: I headed to the kitchen, ripped off a good-sized sheet of food clingwrap (like Saran Wrap), painted the bedsheet in the colors I wanted to show through, and laid the wrap on top with a little landscape cement. You can make it smooth or rippled, and it looks great!
I hope these help.
Bill”
Thanks to Bill, Joseph and to Mickael for sharing his HO scale rock tunnel forms.
I thought his tunnel entrance looked great. So simple as well (all the best ideas are!).
That’s all for today folks.
Please do keep ’em coming.
And if today is the day you get started on your layout, the Beginner’s Guide is here.
