Today I am just working on a gondola with a broken section.

I start off with a mold on the good side. Construction paper and blue tape.

A few hours later. I chipped the edges to free the shell up.

Neat, do you use plaster of Paris for this, or a secret recipe? Last time I was at Hobby Lobby I saw a resin casting kit but it was around $70 but they have 40% off coupons all the time.

Construction paper and tape make a box around the object.

Plaster is mixed with water and poured. Dry time about three hours I may add heat with a heat gun to warm it up.

Intricate surfaces are difficult because of breakage. On the mold I do paint it with craft paint and that helps the epoxy separate.

This is the good side to the gondola. I molded this then I flipped it over to the bad side and added epoxy to the hole.

When I started I bought a small package at Lowes or Home Depot and practiced on box cars, caboose and gondolas.

I came across many broken roofs using this method the cars were improved. The only other method is to cut a piece out of a scrap shell and epoxy it to the new.

Mold and epoxy

The molds were old and reused.

This corner was a little thin after sanding and I had to add support it from the bottom.

A little detour, frame and trucks.

Some wire action was needed. Primed and painted. The lamp socket was cleaned with a small Dremel brush.

It is brush painted. I could of added a little shine but it is close.

The other caboose is the same number but more red in color.

It is hard to resist a caboose with a light and battery box.

The tower of dots have the edit button. For a moment I thought I would have to delete and rewrite the post if I could not edit. Also this is a full size picture. The rest of the post shows thumbnails that you can enlarge to see.

You are right Ed, full size is better. The dark mode is better. I am still getting confused with the screen. There just is not enough boarders. I view a thread then I jump to more threads?
