      I've been asked by Management to show you the ancient art of styrene How to make anything out of styrene sculpting, so here goes. Today we're building an exhaust system with lots of curves, clamps and of course a muffler. These same techniques can be used to make any part, and in fact were used to make the engine.



      First, figure out where you want the pipe to go. In this case, it needs to make a 90 degree bend out of the turbo. Start by cutting a flat sheet to the shape you need. I used .060 styrene How to make anything out of styrene sheet here.



      Then cut a bunch of squares that fit the piece you just made. Glue one to the back...





      ... and trim around it. Don't worry about precision cuts, just get it in the ballpark.



      Repeat until the part is as thick as it needs to be.



      Rough cut with a Dremel How to make anything out of styrene sanding How to make anything out of styrene drum and X-Acto



      Final finish with an emery board or sanding How to make anything out of styrene stick.



      Test fit often during sanding How to make anything out of styrene .



      An exhaust that falls off the car is no good, so you need clamps. Two layers of .040 makes the back of the clamp...



      ... and a wrap of 1/32 half-round makes the band. Clothespins are real good for holding parts while the glue sets up.



      Now for the nuts & bolts. Roll some 1/8 hex rod under your knife to make a shallow cut all the way around.



      I hope you can see the cut. Next, make some cuts from the end to reduce the diameter down to the line you just cut. Once you've gone all the way around, you'll have:



      A nut with some "threads" sticking out. I suppose you could run a 00-90 How to make anything out of styrene die down there and really thread them if you wanted to, but since these parts are going to get rusted anyway, a rough cut is good enough.



      Assembled clamp.



      Now do it again. The elbow fits a 7/32 styrene How to make anything out of styrene tube that goes down along the firewall, but we need to transition again to the rocker panel.



      Same as before, build up enough layers to rough out the part, and fire up the Dremel How to make anything out of styrene .



      And now you've got this. I decided to make it one of those cheeseball flex pipes, but the camera battery died while I was documenting it. You can see in the final pic how it looks with some .005 strip wrapped around to simulate the flex pipe construction.



      You don't want to get a ticket, so we need a muffler. End panels are .060 and the wrap is .010, just go around until it's together. You could sculpt the muffler using layers, too, but making it hollow makes for a lighter part that uses a lot less material.



      Add more clamps, a cut-out pipe and a hanger, and now we've got a street-legal exhaust.

    Did I mention you could make anything?



    These letters are less than 1/8 inch high, made from .010 so I'm about blind right now.

  7. Three days ago this was a pile of styrene How to make anything out of styrene sheets.

    The biggest part of styrene How to make anything out of styrene modeling is being able to see in your head what shape you need to cut out.



    One thing you can do with metal that you can't do with styrene How to make anything out of styrene is shrink and stretch. While styrene How to make anything out of styrene has a little give to it, something like the roof panel of a Firebird needs a little extra work. Here you can see the pie cuts I made to pull the back corners down and in. The peak at the center of the roof, not much you can do about it except sand How to make anything out of styrene it down. The roof panel is .080 thick, so there's plenty of material there for sanding How to make anything out of styrene .

    Hi OBH, Watching that plastic stock become a car is inspiring. A question that you may have answered some time ago - what is your filler? It looks like the automotive glazing putty How to make anything out of styrene that I use.

  10. Putty How to make anything out of styrene 's putty How to make anything out of styrene for the most part. This time I had some Bondo glazing putty How to make anything out of styrene left over, so that's what I used. Squadron How to make anything out of styrene Green is similar, solvent-based and easy to work with.

    The less putty How to make anything out of styrene you use, the better. If you need more than 1/16, go back and lay some more styrene How to make anything out of styrene on it. It'll be stronger and won't shrink when you paint it. I've found that big putty How to make anything out of styrene blobs will re-liquefy slightly when the paint hits it, and shrinks down leaving cracks.

    If you can't fill in the gap with styrene How to make anything out of styrene (like on a metal part) then use a 2-part polyester putty How to make anything out of styrene . USC Icing is my current favorite, but the more I do this the less putty How to make anything out of styrene I use. There's less than a teaspoon in the Firebird.

    I guess putty How to make anything out of styrene ain't putty How to make anything out of styrene after all!

    Here are some photo's of all scratch built How to make anything out of styrene model's that a friend of mine built.
    The tire's are the only thing that was not scratch built How to make anything out of styrene .
    I'm not tring to over ride your post.

    I'm just showing more of what can be done when you set your mind to it.

    There's some serious backyard engineering going on here!!

    But, your engine "weathering" is quite amazing.
