representing cast steel
|
Bud Rindfleisch
Hello again,
Well, OK, my caboose question from a week or so ago was probably sent to the wrong list, so am trying this "modeling" question. Has anyone tried to simulate the rough finish of cast steel on styrene? I saw a couple Krylon spray paints that might have some potential in their "Fusion" line. Made to spray on plastics, one is just a texture and the other more of a mottled finish, forget what they call it offhand. I realize that Krylon is not your average modeler's paint source so am looking to see if anyone else tried a better way. BTW, I'm trying to represent a cast steel tender underframe as used on (oh, oh, here's that caboose word again)a Lackawanna 900 series steel caboose......as used in the steam era behind steam era freight cars. <G> Bud Rindfleisch

From: bud9351 Well, OK, my caboose question from a week or so ago was probably sent to the wrong list, so am trying this "modeling" question. Has anyone tried to simulate the rough finish of cast steel on styrene? ----- Original Message ----- Yes. There are several ways. 1. At the hobby look for Mr Surfacer 500 and Mr Surfacer 1000. These are primer-surfacer compounds similar to very thick paint. The 500 uses a coarser filler than the 1000 and gives a correspondingly rougher finish. Just paint them on the plastic and work it a little bit with the brush and/or stipple it. If it gets too rough you can smooth it out with liquid cement or fine sandpaper. In this photo the gray areas have been covered with Mr Surfacer: http://www.missing-lynx.com/gallery/usa/t10_zaloga4.jpg And you can see the effect here: http://www.missing-lynx.com/gallery/usa/t10_zaloga1.jpg 2. Liquid cement. Paint it on and either leave it or stipple it. 3. Testors or Squadron plastic putty thinned with liquid cement. Paint it on and either leave it or stipple it. The blue areas are thinned putty: http://www.missing-lynx.com/gallery/usa/szm4a1-1.jpg Painted: http://www.missing-lynx.com/gallery/usa/szm4a1-5.jpg HTH, KL

Kurt,
Thanks for the tips! What scale are those tanks? Fantastic finish on them. Exactly the appearance I'm looking for! Its not so much the "finish" itself but the way light reflects on those surfaces as opposed to surrounding areas. Bud Rindfleisch

I'm not sure you want to go overboard on texture in smaller scales -
my view is that no texture is better than one that is overscale If you look at a steel casting the texture is that of the foundry sand - very fine grains whih woudl disappear at all but magnifying glass distances. If you need to suggest the effect then the approach I would favour is the use of matt paint as a ground colour followed by light drybrushing with a slighly lighter colour. This is easy to overdo; go too far and you end up with a caricature like some of the over textured military vehicles or some "quirky but fun" narrow gauge layouts In larger scales you may be able to use talcum powder as an additive to your paint to add a little texture or use the Mr Surfacer primers from Gunze menioned in another reply Aidrian

I agree for all but small areas where you might want to show massive
rust and/or surface deteriation. Many of the "heavy weathering" guys (you know - the ones who sell $15 models for $200 on ebay) do this. I have blown baking soda on wet paint to give texture to concrete and this might work for what you want.

Reflective variation is one of the techniques Steve highlights in his seminars and books. If you look at real objects there will be differences in gloss visible (even on things painted the same color) due to weathering, dust, and wear. I can confirm that the texture shown on Steve's models is quite realistic for the subjects, for example, this Sherman tank turret cast by General Steel Castings of Granite City IL: http://www.usarmymodels.com/AFV%20PHOTOS/M4%20SHERMAN/M4%20Sherman%20Left%20Turret.jpg Cast texture did have quite a variation depending on the part and the foundry making it. It ranged from quite smooth to generally coarse along with some that looked like they had been carved, either as a result of grinding off scale or hand working the molds with a trowel. American parts (cast by many of the same foundries as RR parts) were unifirmly smoother than those of other countries, notably the Soviet Union. If anyone would be interested, I wrote an article on foundry symbols of the WW II era that I could place in the files section. It is definitely tank related but there is a lot of overlap with the foundries making railroad equipment. KL

Funny you brought this up. I was reading Tamiya's magazine last night
and they were talking about this product. It's called cast-a-coat. Here's a review of it. http://misc.kitreview.com/tools/castacoatreviewcs_1.htm You might want to try it. Also, Krylon which you mentioned has several different textured paints. Make It Stone! Metallic Textured Paints, Fusion for Plastic Fusion Hammered, Krylon Contractor Tread & Grip, Krylon Rust Tough Hamm-R Finishes. I'm not sure of their suitability for models. They might be far too coarse. Check their website, Krylon.com Eric Petersson Bud Rindfleischwrote: "Well, OK, my caboose question from a week or so ago was probably sent to the wrong list, so am trying this "modeling" question.

Eric,
Thanks for the heads up on the Tamiya product coming out. Sounds like another "safe, easier to breathe" way of doing this. I like the Tamiya line of paints and have had good success using their clear paints as well as gunmetal for turned off marker lenses. The Krylon products might also be worth a look at, not having to worry too much about heavy pigment here. Bud Rindfleisch

Is there a sense of the scale of the finish roughness with this product?

A couple coats of paint mopped on over the years long ago covered any surface roughness. The distinctive thing about castings is their smooth, rounded forms; all outside corners are slightly rounded, and all inside corners have fillets. Often times the fillets have multiple little gussets worked into them. Note the details in the image in the link. http://www.irm.org/gallery/AMOX9499/aaf The plate and bar stock items all have square edges and sharp corners. The castings, such as the poling pockets, have radii everywhere. The structural steel is somewhere in between, as it has fillets in the inside corners. As to surface finish, it all looks the same.

Kurt,
I'm fascinated with the modeling shown in the photos - and would like to try my hand at the military modeling - are there any sites you would recommend or info you could pass on?
