Some modeling techniques

Excellent!

That method of spacing the blades like that also works great for cutting strips of masking tape to mask off waterlines, cheat lines on airliners and stripes. I had forgotten about that until Scott posted his tip.

I made a rolling cutter some years ago with the same method to cut 1/4" wide striping for a 1/1 airplane, then forgot the whole idea until the other night!

This is so good idea

Masking camouflage demarkation lines can sometimes be difficult. Some schemes call for a "hard" line and this is easy, just use masking tape or other mask fixed tightly to the surface. Then there are the blended type where an airbrush can be used freehand. The third, and for me hardest, is a combination of the two, a rather hard line but with some overspray evident.

The method I've chosen to use with my own modification is to place a small spacer on the sticky side of the tape to keep the masked edge up off the surface. Others have used thread or string for this but I decided to try stretched sprue. Simply cut the tape to the shape desired and then add the sprue, sticking it on a little bit from the edge.By changing the thickness of the sprue and its place on the tape you can achieve quite a nice hard line with a blended look to it.

Some modeling techniques

When applying the tape to the model, make sure that the tape does not stick to the surface on the area you're going to paint, and a nice result is easily accomplished. When painting, spray straight down on the edge of the tape and just a tiny bit will dust under the raised tape.

Good method Faster and more precise then to make small self adhesive roles and put it under tape for distance

[Second Air Force]

Exactly so! I don't have any BluTack here at all and had to come up with something. The sprue is easily made to whatever thickness one requires and we have plenty of that material lying about!

Even coper wire (or tin) is great to use

[Second Air Force]

Oh, I hadn't thought of that! I have a large roll of copper wire for scratchbuilding that will work great.

Good one!!

I'm not big into weathering but here is one technique I tried last year for paint chipping. 

You start with a base coat of silver to replicate the bare aluminum that will show through.

You then apply a small amount of water in the areas that you want your paint chips.  Using household table salt and the water to hold it, apply the salt and water in the areas and shapes that you want your paint chips.  Allow it to dry thoroughly overnight.

Some modeling techniques

After it's dry then paint your color coat(s).  When those are thoroughly dry then go back and pop off all the salt that's now under the paint.  When you pop the salt off you'll expose the silver underneath.

Nice Last days I think about making post of chipping method and in followings days I will arrange this

A little thing to add to the painting tips, really not important but handy to do: When I was getting ready to mottle the sides of the Me-262 this morning I decided to use another partially-built kit to set up my airbrush correctly and to practice a bit before painting the "important" model. Not much of a tip, but the practice does get one's mind in the right place for spraying mottled camouflage!
