I have done that before. I actually prefer to do it that way, because there is no brushing resin, and no warping. There should always be bondo, if you are trying to get a perfect product.

How would I go about pepping a piece of sintra? Should I cut out each and every small piece and put it together individually? Should I cut it out in sets and score it to make the folds? What kind of glue should I use; two-part epoxy, normal superglue, etc.?
Any help would be hot. Thanks.
JUSTINIAN 117 said:I built the entire model, and then cut it into large sections to be cut out of the sintra, and then I bent the sintra to the correct angle. I have used just about every kind of glue, but hot glue seems to work the fastest, and it holds well enough for you to reinforce it with fiberglass or bondo.
When building out of sintra it is best to make the basic shape, sanded and perfect, and then go back and add each detail.
I sometimes use acrylic and other plastics, that I cut by laser, and then use Weld On to glue it together. The laser cut edges come out perfect, and the Weld On has a chemical in it (methylene chloride) that melts the plastic pieces together. I try to make most of my detail stuff out of layered pieces of plastic. The plus side of this method is that the parts are completely fused together within 30 seconds and within a few minutes it is completely set up and stronger than the original plastic. Only try it if you have extra time and money, because it will take some practice to get it to work well
The same basic idea should work with sintra, but super glue would probably work the best for the detail.
Hope this helps, and welcome to the 405th.
If you have any other questions, just let me know.

As for cutting... I have a box cutter and a ruler. Unfortunately, I am too poor to do anything with laser cutting. The best I could do is to order some pieces from a local sign shop, but I could probably do something similar with what I have for way less.
Thanks for the hot glue idea. I will definitely use it to put the model together, though I might also reinforce it with some super glue or two-part epoxy (devcon) to reinforce the pieces after it is completely shaped and put together. I'm just a creature of habit like that.
Oh, I also believe in the liberal use of the dremmel. Shaping, sanding, making holes, detail cuts, etc.
Thanks for the Weld On idea, though. When I put together my Mjolnir armor, I will use the Weld On to put the various clear pieces on with.
Thank you so much and could I have permission to repost this conversation into my "Crawl, Walk, Run, Sprint" thread?

Lasers are expensive, but I still use a box cutter and a jig saw and especially a dremmel all the time. The only reason I can use a laser is because I run a sign business. If you make friends with a sign shop near you, they may let you cut some stuff out, as long as you design it.
Weld On only works with acrylics and polycarbonates (most motorcycle lenses are made out of this) and some other plastics. It doesn't work on sintra or resin, unfortunately.
Sure, you can repost any of this.
Just checking for another of you're great updates....Any news?
Yes,
Work sucks...
Sorry about the lack of updates, but Darth Real Life has been hounding me something terrible...
