No. It's the RTV silicon mold making material that's the expense. The Alumilite kit is really the best value as a starter kit at about $80. It includes every thing needed to start casting including an invaluable instructional booklet. Hobby Lobby and Hobbytown sell this product.

It is around $70 at Hobby Lobby for the kit (everything in it). Get your 40% off coupon and your only paying around $42 plus tax. Not a bad deal. I will be getting mine next week.

Aeromarine Products also has good prices on mold making and casting stock, and their staff are really helpful. They can be found at www.aeromarineproducts.com/ .

This is the company from which I get my materials:

 

http://www.smooth-on.com/

 

They have a wide selection of products and kits, as well as being very helpful.

 

Whichever company you go with be sure (if you don't have a vacuum chamber and pressure pot) that the silicone/resin you purchase will perform up to expectations without de-airing and pressure casting. Otherwise, air bubbles can form and ruin your effort.

I have been following this topic, and want to know how difficult it is to cast something. I have a howitzer with vinyl wheels (argh), and want to replace them with resin versions, but there are 8 tires. Is this hard to do? How do I make the mold and then fill it 8x? Help!

Bill, making molds is no trouble at all. I suggest you check out the Alumilite site as they have short videos on how to make molds as well as cast. They also sell all the supplies you will need and to make mold boxes, find an old leggo set and go from there.. I have been mold making and casting for years and can provide any assistance you may need. The only thing I do not know is how vinyl tires will react with silicone rubber.

 

IF there is no problem with vinal and silcone, you can make one mold of one tire, or two ties or the whole 8 if you wish. I would suggest mor more than four and casting time after mold is made is generally 24 hours, so in 48 hours you could have all 8 tires cast.

 

Good luck

The Alumilite starter kit is a solid choice if you're just getting into resin casting because it includes most of what you need and takes some of the guesswork out of the process. Another thing to consider is the shelf life of the materials—if you're only making a few molds, smaller kits can be more economical since RTV silicone and casting resin have limited storage life once opened. Whichever brand you choose, I'd recommend spending a little extra on a good quality silicone for the mold, as that's usually what has the biggest impact on capturing fine detail and producing durable molds. Starting with a simple one-piece mold is also a great way to build confidence before moving on to more complex projects.
