I can tell you how NOT to do it- so far!
1. round off the end of a dowel with sandpaper and attempt to press the brakewheel into a soft pad ( self healing cutting pad)
2. Same with a blunt end of a drill bit!
3. pressing the etch down over the said drill bit with your finger.
3 for 3 on destroying etched ones that way!

Possibly a bending device like this could be made of wood or metal. Then a bit pre-heating the brake wheel and a careful knocking should suffice.

The other thing that comes to mind is to use different filter screens for grills and mesh.

Not to mention some fabrics that can be stiffened with paint and/or CA.


i've looked into this but never found any filters, nor any fabric with rectangular slots.

not saying they don't exist, i am sure somewhere in manufacturing, someone makes rectangular mesh for some purpose, i just haven't found it yet.

as the 'apex' pattern seems the most common in north america (or at least it's the one all the RTR manufacturers did) i think that may be a bit of a problem.

let me tell you it is kind of funny when you go to the costumemaker shops in london's west end theatre area. they see you poring over huge rolls of cloth, and think they have some kind of professional dressmaker or fabric expert on their hands, and ask how much you want, and you say 'oh, about a square foot . . .' one elderly woman wearing more makeup than gene simmons almost threw me out.

i also tried scribing clear styrene with an apex pattern and lightly rubbing artists pastels over the top so the colour would lodge in the grooves. the effect is ok, certainly no less prototypical than solid roofwalk castings used in most HO and N, but it wasn't uniform enough, and i prefer the the see through look of the etch.

i think one of plano's current etches will solve my problems, but i'm prepared to throw the might of my purchasing power (ie, not much) behind marquette's bulk order.

I'm almost crazy enough to weave my own out of fine wire...

Almost.

Anybody brave enough to order something like this, in different gauges, to see if it would work? http://www.twpinc.com/twpinc/products/C ... /TWPCAT_33
or http://www.twpinc.com/twpinc/products/CATALOG1/TWPCAT_9
or http://www.twpinc.com/twpinc/products/C ... /TWPCAT_11
I wonder if some types could be used for walways (insect ones seem to have rectangular pattern) ans some can be cut to make ladders...

I am definitely interested - when the time comes. Right now the #1 priority is to get a shell and chassis solution. All the details will be deal with after that. Thanks for the link!

In regards to the mesh like materials, there are some etched products already available from companies like K&S Metals (http://www.ksmetals.com/) and Special Shapes (http://www.specialshapes.com/). The ones in the picture have both square and diamond patterns.
