What tool should I use?

Yea Im working on a genset project and it's to make this GP38 shell into a BL20CG.

I was using a electric sander/file to file down the filters and fans and such but it was working only so much.

What should I use to file down the radiator grills and cut off the turbo hatch?

A dremel? file?

power tools are too fast and create too much heat for working styrene.

use a razor knife to remove most of the material bit by bit, then file or sandpaper stick to finish.

I've gotten to enjoy using my Dremel, which offers just about any accesory possible for any job. It's a tool that any model maker should not be without.

For the DB fan and grids,Athearn(if you can find it) made a part that replaced that part of the roof with a plain roof and exh stack,slice+
dice a SD-45 shell for the flared radiator section on the roof.
go easy with power tools,and finish with files and sandpaper,take the time needed to do it right.

you could just cut them out and fill with styrene. Or if you keep sanding till its decently flat, then use putty to try and smooth as best as possible.

Ok, Thanks guys. I have a tube of putty I never used sitting around here somewhere.

Take it easy there! Models are sensitive, no need to use the "big guns" on them.

If you want something removed, drill a series of holes around the perimeter (make sure that none of the holes pass the "border"), and then cut between the holes, "connecting the dots". This is the best way to cut out a particular section, whether its a radiator or a fan. you can use a pinvise for small sections, or a dremel for larger jobs.

remember to use common sense!
