I've found my original purchase, both 30 and 60. I think the 30 is about right for Falcon's mesh, and also for the Westerns.

Mine is copper. The stuff on his site at the mo, labelled "coarse" would give a hole of 1" square, with approx 0.5" dia wires.

I don't think that JeffP meant for the frost screens on the sides of the locos (these were a honeycomb pattern) he was thinking about the mesh above the roof fan. Looking at the web site I think that I'd be looking at 20 or 30 mesh for that.

OzzyO.

And they're (body side) etched/laser cut/punched out/ on the real thing, not woven strands.

It was the Western detail photos on Brian Daniels' website that showed me that an etched roof grille wouldn't look right.

Hello Tom,

I'm sure that's what I said, I don't think that they would have etched out the real things being that the frost grills were about 1/8" thick. more like punched out. All you have to think is when the locos were built.

You have to take scale into account. The woven wire pattern shrunken down to 1:43.5 is surprisingly tiny but to take account for the fact it's woken the Shawplan etch is carefully layered with half etches to simulate the woven effect.
How thick are the actual wire strands on the mesh you bought, and does it cut easily?

Cheers

Depending on the size of the mesh it varies from 20swg down to 49swg.
If your thinking of the 30 mesh it's 32swg or approx. 0.28mm.
Or the 40 mesh it's 34swg or approx. 0.23mm

I'll have to find the micrometer and check on wire strand thickness for the stuff I have.

I remember buying it because it was almost dead scale both in wire thickness, and in hole size, for the works drawings I have for Falcon. I was surprised it was so close, and bought stock immediately.

It can be cut to shape and size with my modelling scissors. Being copper it takes solder and the edges can be strengthened using solder or superglue if necessary, but will be under the support flange anyway.

I have been away for while on business and holiday, I took the California Zephyr from Chicago to Sacramento only 9 hours late ! Then came back on the Empire Builder, its amazing how busy the railways are over there, especially in North Dakota where new track and sidings are going in all over the place to cope with the oil boom from fracking there.

Here's a few things I saw along the way starting with some Metra locos in Chciago

One of our Amtrak locos that went all the way to Emeryville

A freight passing through Salt Lake City

A mixed freight at Albany Oregon

And finally a grain train passing through Albany on Sunday morning

I have been doing a bit more on the 40s, at the DEMU show I bought a Shawplan fan grill it was £20 ! Its their 37 one, unfortunately you need to remove the detail that JLTRT has cast on the roof and then stick on the replacement panel with the grill, you then need to about back a strip. There is a difference in size between them, I don't know who is right but the Shawplan looks good int he end.

Shawplan's was produced after measurements were taken from the real thing.

For those squeaking about the price, is it really that expensive for the base plate, the mesh, the fan blades and boss, the research costs, the production costs, etc. etc. for something that is accurate. Don't forget it's someone's livelihood. Put it in context - other suppliers charge £20+ for a set of nameplates...

You can't expect a Rolls-Royce for a Passat price!

Ah......I thought it was just the grille.
My apologies to Shawplan.

Brian's parts are really superb - if he was supplying military modellers he'd be able to charge a lot more! For what you get with the more complex grilles and parts, they're really great value :) For 4mm diesel modelling, Brian has really advanced things beyond all recognition! Even if you don't need anything from him, it's worth looking at his stand at shows just to have a look at the standard of the etchings!
