Re: How to re-scale an existing item used in S.S?

Yeah, I can send you a photo. I'm not sure if I will be able to upload the picture in here or not? Maybe if I send it to your e-mail if you want to PM that to me? I think the Koolshade is laid flat anyway when it was used to fit on the studio models, so no angle unless you need the angle? It is alum...

How to re-scale an existing item used in S.S?

So, this might sound weird.It's certainly an odd subject so I'll get right to it. So, what I'm going to attempt to do is re-scale and hopefully scratch build something used on multiple S.S miniatures. Koolshade. Yes the window screen louver material used to cover the S.S Tie Fighter, but it was used...

Re: Styrene cements and construction

I can't get "real MEK" in California let alone Acetone, White/Mineral sprits, Lacquer thinner and other solvents that would be useful They have EPA approved replacements and I am doubting their use or effectiveness. I'd have to drive to Nevada to get it or Oregon.

Re: Favorite scribing tool MIA

You can make a scribing tool out of allot of things. One would be a very small flat(or phillips) screw driver used for "glasses". You can grind it on a pedistal grinder (if you have one) or you could use K&S brass flat stock. You can file it to make it a little narrower. So you can scr...

Re: Plastic options for making a large-ish sign

No...you can't machine styrene. You would have better luck with ABS, but acrylic would be better(cast acrylic, not extruded). The cast acrylic is better.

Not to my knowledge. Your "standard" ping pong ball is made of styrene, but you can use MEK to melt both styrene and ABS plastics.

No, I've no plans of painting any vinyl kits with artist oils or enamels. I was told by someone anyway that is doesn't matter if you have acrylics down as a base over your vinyl kit. It won't protect or keep the oil(or enamel paint) from reacting weird and basically effing up your project. I'm refer...

Re: Aliens Dropship Paint scheme

I'd say its a military green/drab, or olive drab/brown drab color and who knows if they didn't use more than one color(change it in between painting it) or due to weathering changes the color entirely, plus there's all the blue screen film, lighting, whatever else they used for cinemaphotography.

Re: Dust! How to vanquish it?

A tac cloth is good for smooth surfaces, but if your kit has allot of raised and recessed surface detail...not so good.That's why(if you can) washing the kit is better and does two things.Removed any dust/dirt and also removes the mold releases.

Its not just the cement. I think you need to "wash the kit parts". That "waxy feel" to the plastic is probably mold release. Strong mold releases are used in injection molds. Get a dish washing tub, fill it with warm warm water and dish washing detergent(not scalding hot, you'll ...

Re: working with ABS

I might give that a try. So, ifPVC cement is 30% MEK, is it just a slower cure, or it doesn't melt the plastic as much? I still may be able to get it (and a number of other solvents I am in need of) from someone, but it depends on what it costs and how big a risk there might be.
