Hi all
This is my very 1st post on this fantastic site which i have been "visitin" basically every day. Im part of a very small modelling group in PE and am the first of my age to buy an airbrush. The model I purchased was the badger 100LG medium nozzle and i was wondering whether anyone who has one or has used one can comment on it? ive ordered it from the states and its now en route..so im holding thumbs! all comments welcome and thanks in advance

Well, I've been using a 100G for a while, and have had no problems with it.
The only difference between the 100G and the 100LG is the size of the cup on top. Yours' will have the larger cup.
It uses the same heads and needles as the Badger 150, so you shouldn't have any problems getting hold of replacement parts if and when needed, as the majority of the parts are the same for both airbrushes.
You can use any of the heads and needles for the 100LG, the Fine, Medium and Large heads and needles will all work with no problems. (I can use the Large set up on my 100G, with no problems except it sucks the smaller color cup dry really fast, but I normally keep the fine head and needle on mine) My Badger 150 I normally keep as a Medium head and needle set up.
Cleaning the 100LG is a pretty easy job. Just remember to 1. remove the head assembly first and then remove the needle from the front, to avoid any dried paint from scoring your Teflon needle bearing. It will last a lot longer doing this. Also do not lose the small Teflon Gasket on the head assembly, and make sure it's there when you reinstall the head. Use the wrench the comes with the airbrush to tighten it and it really only needs to be snug. If you over tighen it you run the chance of 1. splitting the gasket, and 2. stripping the threads. Install the needle form the rear after you have installed the head assembly. Really is a simple brush to clean and maintain, and really doesn't take me longer than a few minutes to do a good complete cleaning on. The cleaner you keep it, the better it will perform, and the longer it will last. The Medium and Large heads and needles are pretty robust. Have fun, enjoy it, and practice a lot.

hey grumpyoldman thanks for the advice! ive used an airbrush before but it was an aztec single action and the compressor was notoriously poor, so results varied.. but now i have a compressor with a pressure regulator and moisture trap? i was wondering what is the best pressure to operate on? do you use different pressures for different affects or does it not make a difference? im specifficaly interested in pre and post shading techniques and the pressure needed there

Well most suggest thinning paints to the consistency of milk. What ever that is. :-) :-) I usually start with 2/3 thinner 1/3 paint, and take it from there.
Just remember the thinner the paint, the lower the pressure you'll need.
Since I have such an exacting mind (What's left of it!) I just use one eye dropper of paint to two eye droppers of thinner. My normal (Again what ever that is!) pressure ranges from 15 psi down to 7 psi.
Just experiment on a scrap model or two, and do a lot of practice on some illustration board or something similar.
I also use 90+% enamels or lacquer base paints, so have no suggestions on using or thinning acrylics- sorry- can't help in that area.
