It's right alright. The tube has sat for awhile, and the parts have separated. You need to shake it up, and squish it around inside the tube to get it all mixed up again. If you squeeze out too much of the runner red stuff, the rest of the putty in the tube will be too dry, and thick. But it will st...

Always put decals on a smooth gloss surface. :) Even if the final colour needs to be flat. Use the gloss version of the colour you want, clear coat, decal, clear coat, and then dull coat if needed. The reason for clear coating before decals is give you a barrier in case you mess up the decals and yo...

Get the biggest, most powerful one you can afford. Really. Since you are a Canuckian, Canadian Tire has sales all the time. Look for something in the 3.5 SCFM @ 40psi (casting pressure) or greater. They should have all the other bits you will need as well. AND, if you don't have one near you, they d...

Cardboard is fine. The coated stuff (like cereal boxes) is better. Some of the surface paper may come off, and stick to the mold. To reduce that, just spray it with mold release, or grease it up with Vaseline. Or, you could line the box with white printer laser paper. I use old paper (print outs tha...

Anyone know of a place in Canada that sells these pressure pots? I'd rather not import it and deal with the duty if possible. Importing (with duty and taxes) is still cheaper than getting one in Canada. I just picked up a 10 gallon pot for $100.00 from the US. The exact same pot here in Canada can'...

How long are you letting the cast sit before demolding?? SC305 is the SLOOOOOWWWW set stuff. It calls for 30 minute demold time, leave it for at least one hour. As modelnutz mentioned, temp is a factor. As well as something called cross sectional area. Or, in layman's terms; the thicker the piece, t...

Re: Gentle Peoples....I seek inspiration!!!!
Do you design by building or design on paper? Do you use a CAD design program? Yes, and yes. It all depends... Randomly open threes kits, and put the parts on the bench. See how they might fit together. It may not be the design you will build, but it might inspire you with shapes, and patterns and ...

No problem. Glad I could help. If you use your resin quickly, or semi-fast, you don't need to do that. Just make sure you can seal the containers well. For your vacuum pump, how much air it can move is not all that important. How strongly it can pull that air, that is what you need to know. For dega...

This gas system, or any inert gas, is designed to minimize the amount of moisture than can leech into the resin BEFORE casting. Once you break the seal on the containers of Part A, and Part B, the resin begins to absorb moisture from the air. By removing the air, and replacing it with an inert gas, ...

Resin will stick to resin. But... Surface prep, like with paint, is important. Any contaminants on the surface must be removed. Best way is to sand the surface with 220. As for gluing the metal... Did you use epoxy?? That's the way to go. CA, and others will/can fail over time depending on the stres...

OK folks, I switched from my trusty GI-1000 to Smooth-On's Mold Max 30. I have now poured my first set of molds. I am both delighted, and disappointed. It's mixing/pouring quality is great, feels no different than GI-1000. The cured MM30 is great. Feels and behaves just like GI-1000. But... That lit...

How much curve?? It has a bit of a memory. So you can just bend it (gently). It will spring back, but not all the way. Repeat as needed. As far as the oven outside issue... Not an issue. The only time you have to worry about it is if you do catch it on fire. But if you keep the heat down below it's ...

Yes, you can do that. The melting point of styrene is 240 °C (460 Fahrenheit). So, you can do a lot with it BEFORE it melts. It's the main plastic used in vacu-forming. The main issue with heating styrene, at least with sheet styrene, it has a tendency to curl. A lot depends on what kind of forming ...

Something thin, and slow setting. While an epoxy isn't thin, the slow set time allows you to add just the amount you need, and time to place it properly. In many cases, I don't even use glue. I have set the PE parts into a wet coat of primer, and then once dried, apply a second coat to seal the part...

Does it have an AC outlet on the end?? If so, then the third wire runs power from one end to the other so you can plug another set into it.
