HI RR!
Welllllll, you are loking at one very tedious job!! I do brickwork in my trade. I've done circular stuff and it is actually easier in the "real" world doing 8 inches at a time. The perimeter will be the easiest but as the radius decreases it gets tough. I think you know this. A real brick pattern, a "running bond" staggers the mortar joint exactly in half in relation to the preceding course. Unfortunetly the bricks need cut, usually on one side, at a slight angle to keep everything in line. the angle gets stronger as the radius grows smaller. OR the mortar joint absorbs the angle and the joint looks triangular. I am somewhat curious as to how they did the real one and how long ago it was done. The old masters knew a lot of tricks and also had a lot of time. To do it in scale would be mind numbing!! What material would you use??
Thin styrene sheet, brick embossed, could be cut into strips and maybe softened with heat. or, plain styrene sheet scribed with an xacto knife and compass.
Drywall guys have a tool like a large campass that holds a utility knife blade. Good luck to you in this. It will be quite an accomplishment!!!

Did you think about printing one? Of course laying out the pattern on the computer is no piece of cake either.

I would either make it in clay and cast it, or lay down a surface you could score (joint compound?) Measure off the concentric courses with a ruler from the center and then score them with dividers or a compass (or make a trammel) with one point on the center. Then put a pin in the center and holding a ruler against it at one end, score the grout lines between the bricks in a radiating pattern. You could measure these or carefully do it by eye.

Careful paint the top only (bricks) stain the grout and voila!
Would you notice a curve. Most brick today is a little short of 8" (.166"scale) X a little short of 2 2/3" (.0556"scale) I'm thinking to do this you would probably want to simulate bricks at least twice that size which would still be interesting.

Anywho. This is how the pit looked NS Conway yard, Beaver County Pennsylvania.






The pit is used as a collection basin for all water and other fluids from the engine facility. Collected waste water then is treated at an on site plant to remove all that wonderful stuff you see.

We, Anthony, (Lurker 2004), and I got a really good tour that day. We were asked if we wanted to go down in the pit, but declined. Eek






We eventually did a gravel/fine ballast base in both model TT I am responsible for.

You could do it using individual bricks -- 1/35 scale bricks used to be available from the 135th Construction Battalion. They are what I used to build the chimney on this store/home.



I will confess and advice however that your health insurance be fully paid and cover mental illnesses since pursuing this using individual bricks may impact your well-being, Wink

What I am going to suggest is tedious, but I find very rewarding.

I use Evergree stryene strips #123 for alll my brick work. I perfer crisp edges and deep morter joints and like the iregular look of hand layed brick work, I use light weight weight joint compound as grouting. Look at my work in proces section of my web site for examples.

Thanks guys,

I just heated the pen to give it a squared off shape. I think I inserted the handle end of a file. To do bricks, you would have to use something smaller than a pen to get the right shape and size.

I just pressed the end of the pen into the wet spackling. If I recall, I used two different brands and the optimum wait time was different for each one so you will have to experiment. The color is then just dry brushed on.

Pete,

It has that Smallman St feel to it!

It would be very tedious and it might not give you the texture and depth you want, but you could paint the base the mortar color and cut the bricks out of brick paper. This would allow you to easily trim the "bricks" to get the circle pattern you need. You would cut out a lot of bricks and you might need a marker the color of your mortar to run along the edges, but you can get brick paper printed on thick stock from Fred Dole that might work for you.

If you have unlimited time you could make a template and lay the bricks out on it to see how it would work.
Jim,

One possibility might be to lay down a layer of drywall compound and then use a compass with a scribe type point on it to scribe the circles. You could then scribe each of the brick ends individually. As others have already said this would definitely be a tedious job but I think the result should be just what you are looking for.

If you end up doing the brick in some fashion I'd love to see pictures.

Thanks,
Ed

Vulcan,

Got the paper.

When I was in HO, I bricked the floor of a turntable pit by cutting brick sheets into pie shaped wedges. Laying them out was tedious, but the effect was terrific. Today I would use a computer cad or drawing program. I think using a paint program like PhotoShop would be extremely difficult.
I've made individual bricks, stamped, etc and found the fastest, most versitile way is to lay down the medium (mortar, cement, plaster, whatever) and before it dries, scrib brick lines. If you want 2 tone, lay it down dyed white, let dry, lay second coat in whatever color and scrib to the white
