The Dr. Grunge Advanced Wood Clinic

edited January 2017 in Working with Wood
Following much procrastination, I call it detail planning, I am kicking off the Dr. Grunge Advanced Wood Clinic. It was suggested that I contribute to this clinic, as I would not have been so presumptuous to have started this on my own. There are so many wonderful modelers here on the forum that I am humbled to be able to "knock elbows" with you guys and talk some shop.

First and foremost, and please remember, the techniques and methods are not "how to do it", but rather just "how I do it". We are all unique in how we go about detailing stripwood. There is no right or wrong, success or failure, however, to achieve a desired result there are some guidelines.

I cannot over emphasize the contribution Brett has made to this hobby and to the "science" of detailing stripwood. If I don't have anything else, I have enthusiasm! I studied Brett's manuals and his methods for detailing stripwood and came to the realization early on that if I could, in my mind, master the art of detailing the wood I would be well on my way to achieving the results I envisioned. Brett instilled in me the concept that the coloring, detailing, and general care of the stripwood is the single, most important, factor to a realistic and quality model. I took this to heart and spend more time and get more enjoyment out of working with wood than anything else. It lays the foundation to the character and story your model will betray.

I stated "Advanced Wood Clinic" which I believe warrants some clarification. Brett provides comprehensive instructions for detailing stripwood in two main formats:

1. The manuals included in each and every SWSM kit. My advice is study these manuals carefully. They are tried and true methods and if followed will result in a superior, beautifully detailed structure.

2. The Craftsman Kit University, accessible from the SWSM Home Page. Go to Online Clinics and then select
"Adding Texture and Details to Stripwood". This is an excellent tutorial that compliments the manual instructions. This tutorial is supported by the video link "Adding Details to Stripwood".

With this plethora of detailed information Brett provides on detailing and finishing stripwood, it begs the question; why have the clinic presented here?

Brett lays the foundation for quality, highly detailed, stripwood in the above tutorials. However, the modeler will develop his or her own variations, techniques, and styles. This clinic will explore what I like to do with my wood and how I achieve the results that you've may have seen here on the forum. We are attempting to do in an afternoon what nature and the elements take years to do. So, if we are able to achieve this type of weathering and detail in a short time...that's some powerful stuff and creates a structure full of character and realism. So off we go...


This is our first glimpse of our beloved SierraWest Scale Models stripwood. This gathering happens to be from the Loco and Service Shops kit. Brett carefully packages and sorts the stripwood and seals them in individual labeled bags. In my experience his wood is always of high quality, details beautifully, and is sorted and packaged for ease of use and assembly.


So...grab a fist full and lets grain and stain some wood!

Is that a BlueSky Company Warehouse manual?...more on that later.


  • Ken,
    As you know, I am always asking you how did you achieve that look? Your weathered wood is exceptional and the results are, in my opinion, what we are all trying to achieve. Is the magician going to let us see how he does it? I hope so.
  • Oh yea Mitch...this is just a preamble...much, much, more to come...
  • Doc G... well lets sit back and enjoy the way this grunge master makes his stripwood look so fantastic. I asked Ken to create a forum clinic for us detailing his award winning methods for creating the grungiest wood around. He graciously agreed to share his secrets. Very excited to watch this clinic progress!
  • Ah Ken, thanks so much for starting this clinic. This is a perfect time. I am so looking forward to it. It is going to be great!

    Thank you Ken for providing your expertise. Brett's techniques really got me to appreciate the finer art of this hobby since I started buying his creations, and with your input, I can only hope to gain more valuable lessons. I have learned so much from the artists on this forum. Thank you to you all.
  • Looking forward to this Ken
  • Thanks Brett for the intro. and look forward to getting into the subject at hand. Thanks guys for your support of this thread, should be fun...Ken
  • Carl, This is going to be real cool. I want you to pay attention, and please be very respectful of Ken in your comments.

    Ken, I hope that helps control Carl. I will give this the same attention I gave my instructors at jump school. Brett has chosen a special person to conduct this clinic.
    Should your enjoyment be equal to ours.

  • Ken, thanks for doing this. I can't wait to see your version of preparing wood. Also, I'm going to hold you to another clinic about "rust." That's where I really struggle.

    Happy New Year. Phil
  • Yes Phil, I agree "Rust" would be another excellent clinic for Ken to do.

    Hey Kenny...I'll be following along. Cant wait to see if you share your "special ingredient" with everyone or you decide to still keep that a secret. As they say, a Great Magician never reveals all of his secrets.

  • I'm sure it will be fun and entertaining at the same a trip to Epcot.
  • I'm following along Ken. Looks like it'll be a great tutorial.
  • I am lost here who am I going to follow and where are we going?
  • Well looks like we have a decent following with everyone poised for some miraculous, astounding, revelation in stripwood! Sorry to disappoint, as a good bit of this will be review of information Brett has provided since the first SWSM kit hit the market back in 1995. Brett knew then what we all know now, thanks to his tutelage, that texture is the secret to realistic modeling.

    So, am I going to move right to adding texture to our stripwood?! If you're looking for a thread on stripwood detailing that's a few paragraphs long, this isn't the one. My plan is to take you through my entire process including my thoughts, philosophy, methods and peculiarities as it pertains to detailing my wood. Very little is my own and anything that appears to be my own was likely spawned from others work. I do however, hope I have developed my own style and many of you have expressed satisfaction with the results I have obtained. All techniques are within the scope of SierraWest Scale Models materials. No mysterious solutions with "eye of newt", or any concoction that will take a dedicated internet search to obtain. Any errors are my own but I take no responsibility for shoddy modeling! A phenomenon I have yet to see on this forum. I don't rush my modeling, as most of you know, so I'm not going to rush through this.

    So, have I lost a good number of you?...good...then we're down to the serious modelers.

    I'll get into what I do before actually working with the wood tomorrow...

  • Carl, It's all aboard the night train. Conductor Mr. Ken Karns and his magic show.
    This will be a trip. Better than Easy Rider.
  • Wow! I'm back from vacation just in time for this to get underway!
    Your structures (and specifically the wood) have qualities that are different and unique, making them unmistakable as a "Ken Karns" project. I'm SO looking forward to this.

    If you're taking attendance, mark me as "present"!
  • Here's another Bill that will be present!! And a front row seat for my poor hearing.

  • This is coming along at the right time. I have been building a new layout this past year and I need a change of pace so within the month, I was going to start work on Shelby's Marine. You have another person who is looking forward to your tutorial.
  • ED Do you have your ticket yet I think Alan is selling them.
  • Present!!!
  • Carl, Have no fear. Ken says we are so cool, he is not going to charge us.
    Plus between you and me, he is charging Alan so much, it makes up for it.
    I got my Packer tickets.
  • Ken, do I get in for half price seeing Carl and Ed get in free?? Besides they are outstanding modelers whereas I am not and really need the help. I'll even bring you a Washington apple every day.

  • Bill, Dude you are in. I know I speak for Ken, but age has it's rewards. Plus for calling me an outstanding modeler, if you get a bill, I got you covered. And we all need help. That's what this forum is all about. Sharing, because we give a damn.

    Don't take the Lions for granted. Seattle better show up.

  • Apples you here that Ed. Teachers pet.
  • I've got my pencil in hand so I can take notes. Hmmmmmmm, maybe I don't need notes, it's going to be here for all to refer to at any time.
  • Sounds like the class size is sufficient to continue...thanks for the support guys and hope you find some useful material here and there. Things will go slow and more of a review but will heat up later on.

    The first thing I do, following my studying of the manual and kit contents, is make a decision as to how much texture I want to put into my wood. This is a personal decision based on how I want my structure to look and the character it will posess. This is actually a big deal, as it is easy to add more texture but much harder, if not impossible, to remove it if you go too far. Stands to reason that the more texture that is put into the wood the more weathered it will appear. At least that's what it will look like was being done, which is why the level of texture and weathering should fit the overall structure age and level of deterioration.

    So I have decided how much texture I want and I have my stripwood sitting in front of me. The next thing I reach for is the tool(s) used to create the initial texture. This initial texture is followed by the coloring of the wood which is then followed by the really fun stuff...the individual board details...more on that later.

    So for now the word "texture" will be replaced with "wood graining". Bare stripwood is just that bare. We want to create the illusion that the wood at least somewhat old and weathered. Keep in mind that not everything prototypical looks good once scaled to 1:87 (my medium). I perform wood graining as the initial step for ALL my stripwood regardless of how it will be used, unless of course it's being used where it won't show for some reason. The only tool I use for my initial wood grain work is a small steel wire scratch brush. There are many steel brushes out there and every modeler has their favorite which is perfectly fine. Mine is shown hired hand model is showcasing the type I use.


    This wire brush has the following attributes that makes it my choice for 1:87 scale grain work:

    1. Bristles are not overly stiff. Now this aint science but here's my theory on why that may or may not be important. Stripwood already has wood grain. The wire brush shouldn't create the grain rather enhance and define it...make it pronounced in a hurry like nature does over time. If the bristles are too stiff they tend to make the grain where as the more pliable bristles follow the original grain removing material as it goes. The extreme example is a razor saw that totally ignores the original grain and makes uniform grooves in the wood. We'll discuss this more later.

    2. This brush is very easy to control due to it's small size. I am able to "feel" the brush working the wood, which I like.

    3. The brush is readily available from numerous sources and is fairly cheap to purchase. They don't however, last all that long. This is not a life long tool!

    You guys modeling larger scales, and bigger wood, may want a larger brush. I work with only 2-3 pieces of wood at a time. Any more than that and I feel I don't have the control I need. So I place the pieces on my bench. I use a piece of solid oak wood to lay my stripwood on to brush. I then brush the wood back and forth until I get the grain pop that I want. I have done this enough I just have a good feel for when I've got the level of detail I want. If you're not sure on how much texture you want, perform some work on some test pieces first.

    The following is some stripwood I grained as described above. This wood is from the classic BlueSky kit...more on that later.



    This close up shows the wonderful natural grain that has been worked into the wood. The next step involves fine tuning this wood in preparation for "Staining". I will use the word "staining" to include any method used to color the wood. More next time...
  • I like your take on texture: "enhancing rather than creating" grain.
  • Appreciate your thoughts Bill and really glad to have your wisdom and insight here. Keep an eye on me as I go through this and interject at will.
  • You have beautiful hands. What shade nail stain is that?
