what is the best way to cut out doors on a resin car??seen sewing thread used on plastic, but what about resin??body looks like it is 1/16 to 1/8 thick..thanks oldr-n-drt

You can use the back of a #11 blade just like a plastic body, or you can use a scribing tool . But ( there's always a but ) you need to go slowly and lightly  with resin. Too fast and a heavy hand will cause problems.

I would think you could also use a photoetch sawblade, like anything slow and easy is the way to go.

The old standby #11 blade, either the tip or the back of the tip, or the tip of a razor saw, or my favorite, a PE saw blade...as already mentioned. 

The PE blades from MCG are only .007" thick, so they make a thinner cut than some other methods.

The problem is that they're somewhat flexible due to the thinness of the material they're made of, so you do indeed need to work slowly and carefully.

Opening doors on resin models that are thick can be a real bugger, and if you get the gaps too wide, they're harder to correct than styrene. You'll find it's more difficult to get a good, strong edge that you can re-work with resin.

While correcting a buggered opening on a styrene body is relatively easily achieved by simply gluing in strip-stock and filing to shape, with resin, you'll have to rebuild the bad part with thickened CA, most likely.

Might I suggest you wear a mask when cutting resin.

Where's the fun in that ?

Use the #11 blade as suggested. It will cut the resin easily.

Make a template of the door opening out of a file card. Cut it so the "door" is missing, leaving the outside shape to trace along. Start with a new blade and very lightly scribe the opening, tracing the template as you go. Once you get a decent  groove going switch over to an old blade. I will break the tip off to create a sharp edge to drag through the cut. The sharp edge should peel the resin out very quickly.

Once the door is cut out you can reduce the gap, which is a scale 1/2 inch now, by gluing .010 strip stock to the edge of the door and sanding it flush to the outside and inside.

Also think about creating the door jamb and relieving the door so it shuts against the jamb.

was gonna say the same thing Ray, resin is easy to work with and cut but not something you want to inhale!!!!!!

Sanding should be kept to a minimum also.  Your skin can become sensitized.  Wet sanding is best.
