models  showing the cross section of the planet earth Show difference soil depth  to the core of the earth.Its material is fiberglassFirst I started by carving the foam sphericaThen I lathe model for captive smooth roundI spent about an hour on lathing.Then I took the model to dry by sunlight. If the strong sun, it takes about a day more dry much better.lThis makes it easy to customize polished plaster. When I polished plaster models and the dust does not stick to sandpaper. I do not waste money on paper, with You should scrub to smooth and round models very much as I can. This process will take approximately 1 day.Then, create a the details of the cross section of the model sphere Done this time to create a mold. Prototype made ​​of foam coated plaster. Models made ​​of solid surface materials and more detailed.To be cast as fiberglass, a hard material. Therefore, the material used to make molds, it should be a soft material for easy removal from the mold and get all details. This option has two points, rubber and silicone.The advantage of rubber is cheap it is unfortunate. Short-lifetime decay easily. Even if the air is heated. Or heat from the resin will melt and sticky as Thomas. And a lot of shrinkage. Running time is quite long because

It must apply, and then blow dry layers about 20-30 layer if you do not have the patience I do not recommend. Silicone advantage is robust to degradation and heat. Not shrink as well. Do not apply individual layers paint just about 2-3 layer, and it can dry yourself with a chemical reaction without blowing hot air to dry it properly to people who have money but no patience (remember all the patience of the people will interpret inversely with the amount in his pocket.) Analysis of the advantages and disadvantages compared to the situation now, that is, 1. We are not worried about shrinkage of the workpiece.
2. We have enough time to work, because we manage time and work well. Not sluggish Wake up early. To bed late, not any drink after work. Not like drama series after the evening news (works like a machine) wake up in the morning. I work. Stop when eat only 3. We have patience. Not tired of having to paint, rubber and blow dry each layer 4, we are left with a budget because we have good financial management. Do not squander Accounting and revenue expenditure have savings every month. Money invested in funds in order to profit Or invest in stocks.Or investing in property  To provide cash flow. But we do not need to use silicone, because it is not necessary. Finally, we will use rubber as a mold material, so I paint then blow dryer blowing about 20-30 level will take about 2-3 days if you want to own a number of layers and the less time they use the Scottish fabric. It  make latex rubber’s thickness quickly. And stable.
When mold finish.It’s time to cast fiberglass fiberglass cast will not have to explain much because
Everyone is good at casting fiberglass.

However, I will ask a few tricks in the fiberglass casting. Because much of what I find is often cast a ton of heavy fiberglass.Some thick Some very thin Irregular Surface inside the glass fiber, it is not right.Like a crumpled cloth.The trick, nothing at all.You should only work with complete resolution just that.This works well with all types of work at all. When the fiberglass cast finish.
Later, the painted decoration.I detailed terrain with poly putty not intended to apply to flat(Most of the work of art.The trick is do not intend to do it too much Sometimes.leave it to emotionust Just let your hands do by itself  and it will come out well.)
When finished working on detail, I painted with  acrylic painting using airbrush or sometime brushes Alternating back and forth.Finally it done Prepare to pack and send to customer
