Thanks for all the answers and suggestions. I e-mailed Testor's and they told me that their enamel-based semi gloss clear (FS-3) is still available and that is what they suggest I use to be safe. They have an on-line store that you can order from if you can't get it any other way. I think that woul...

That adapter fits an Iwata airbrush to a Paasche hose. The OP needed an adapter to go the other way.

If there's any way you can put a 2-part automotive urethane clear coat on it, I'd suggest you do it. There are 2-pack aerosol cans available that cost about $20 that will do the trick. It's...

I think Ken nailed it. I use small plastic cups for casting, and any excess resin that is left in the cup gets dumped into another cup. Over the course of a little time, that excess resin from all those pours makes a nice little chunk of resin. I once thought it would be a good idea just to use that...

Re: LED Voltage Question

My question is, can I use 4 of these in series (with the correct resistor of course)? Yes. But they might be a little bit brighter if you split them into two parallel series of two, and give each series its own resistor. Calculate your resistor value based on giving the LED's about 3.3 to 3.5 volts...

A milliamp is one-thousandth of an amp. 1400 milliamps equals 1.4 amps. The power requirements of your LED array is determined by the way they are connected to the power source, i.e. series or parallel. Your three C or D cells can power that many LEDs but you can't just string them up in series and ...

Also check for any damage at the end of the nozzle. If you have some beeswax, rub a little on the threads before y...

As long as you have a good, solid clear over the decals you can weather them with filters. Be mindful of the chemistry, though; the thinner you use with your oils should not soften the clear coat.

The leads on all the LED's I've bought in the past few years are square, so no problem there. I also have no problem using wire-wrapping on the round leads on resistors. You can always put a little solder on the wrapped connection for insurance.
