log-44_0.jpg  This month I have a little progress on a few different things:

I have finally completed my AC Static Grass Flocker Mark I

I have practiced painting my bridge abutments

I have begun to ballast my track.

This is kinda silly, with the magazine coming out tomorrow my timing is poor, but here we go..

 

 

HBlog-47.jpg Becoming a Flocker

My static flocker is made from a length of PVC pipe. I didn't use the flanged pipe that is used in a lot of the online tutorials but rather a pipe I had sitting around from another project.

I used a sour cream container to be the business end of the flocker. I chose it because I like dip! I made locking rings by cutting pieces of the pipe and slitting them in one place. These could be snapped over the pipe and super glued in place. I put rings on either side of the sour cream container to lock it in. On top I used them to lock in the power switch. It's a dpdt switch because that's what I had. The top was made from a circular cardboard cutout taped on.

This was done with the AC version of the static generator on Electronic Goldmine. I used a three prong cord and cut the "computer power supply" end off. The black went through the switch which was connected to the static generator's black lead. The white was joined with the white lead of the static generator with a wire nut. The green (Ground)  wire was fed through a hole on the side of the pipe and connected to a terminal. That in turn is connected to the grounding wire I use to attach to the scenery.

Strain relief was provided by tie wrapping the power cord to the side of the pipe and by knotting the green ground wire inside as well. The red wire from the static generator was attached to a small screen in the lid of the sour cream container. I used a smaller screen then most people seem to have. Its what I had from a screen patch kit. It seems to work fine. I attached it by soldering a brass PC board stand-off to the wire. I drove a machine screw into that trapping the screen between them.

I don't have a lot of images because this is really a throw together. Other then to say the AC version seems to work I don't have a lot to add to the art of making a flocker except to encourage folks not to sweat the details of how you put the pipe and such together.

Below is an example of a test I did using 2mm flock graciously given to me by our own Scarpia. It works as it should. I am very pleased. I used one tip from Mike Confalone (you may remember his Woodsville Terminal from Model Railroader..) I picked up at the Collinsville CT RPM meet this year to use a shop vac to help tease up some of the flock after it set.

HBlog-45.jpg Hit and Run

Another thing I have been working on is painting my bridge abutments. This is a piece that came out my mold poorly. The plaster was too dry and left bubbles on the bottom. I have already cast the two I plan to use that came out properly. However, until I know the final height of my bridge I won't know how high to make the abutments. These will have to be cut down quite a lot (see the track to the left and right...). Meanwhile, I am practicing painting them.

With this one I used the "hit and run" method described in a hand out from New England Brownstone I received at a local NMRA meeting. The other side of the handout was tips from BEST Trains which was the actual presenter. Anyway, its a method where you keep tagging individual stones with various colors of wash building them up in layers over time. I also hit them with a sponge dipped in variations of my base color (Delta Ceramcoat Hippo Grey). I was very pleased with how it came out. 

I also found that by mixing my washes on plastic lid.. the washes got into the rim and mixed together. These made new washes based on my primary washes (Delta Hippo Gray, Delta Burnt Umber, FolkArt Medium Gray, FolkArt Dark Gray, and FolkArt Wrought Iron). Once I get the shoes for my bridge and can measure the height I will cut down and install a couple of these. Then my scene will really start to take shape!

Btw- yes.. these are Chooch N-scale bridge abutments. I love the detail in them. However, I did not like the resin material for painting and cutting. I also can't afford to burn through them practicing my painting. I made a latex mold and made some in plaster of paris castings which paint up real nice.

The Lamentation of the Ballast

This is my initial attempt at ballasting. Its ok. Not what I wanted. The one on top is not done yet. I am holding off until I get some more materials. I want to get some cinders to be a base and I want to mix in a little brown here and there. I got the brown at a miniature store that had not gotten rid of all their stock. I am hoping to get the cinders at the national train show. There is a real dearth of good hobby shops close to me, and I hate to pay shipping on one bag of ballast..

 I lamented my ballasting woes in another thread on the message board.. I wont belabor them here. I am hoping with practice and some new materials it will improve. I will post back more after I get some more time on it in and have more to talk about besides "man this is harder then I thought it would be".

Regards,

Chris

Very Nice

Chris,

I really like the static flock.... remember, its just a game flocker!

Your static grass applicator looks like it could make the hairs on the back of your neck stand on end when using it. You got really nice results. I also like your bridge abutments a lot.

I can see what you are saying about your ballast. My only criticisim of it is that its too perfect a color. I would look at a prototype photo, figure out how much of each rock color is represented in a given area then mix together equivalent percentages of similar colours, then apply. I think it could add some "depth" to the ballast. Anyways, its a great start and you have laid more ballast than I have so take my advice with a grain fo salt... er...ballast!

Thanks for the comments!

I agree. I have some brown which will be mixed in about 20:1 I am thinking to give that occasional rock with some iron content. Also, I have not painted or weathered the ballast yet. My plan is to tone it all down with an india ink wash then paint the middle with a grimy oil wash and paint the edges and around the rail with a rust color.

I think adding a base of cinders will go a long way to making the ballast look more complete as well.

Improving on you ballasting.

Hey Chris,

 

I'm a real fanatic about ballasting, but when I started out, it would come

out all lumpy, and uneven, and looked more like calm water than true to

prototype.

From what I see, it appears that your sub-roadbed is slightly wavey, and not flat

enough. For heavy mainline ballast where it is maintained to look almost geometrically

perfect, I like an overall look to be almost an exact trapazoid if you were to view it

as a 'section.' Spurs, and unused branch lines don't have that pristine look, but if

you can practice on your 'mainline' ballasting, you've pretty much tackled the hard part.

Try practicing on a 3' foot section of tangent (straight) track at first. You can worry about

the curves later. Make sure your 'practice section' comes with roadbed!!!!!

You don't want to glue it down, because you can retrieve the ballast again,

and start over. Practice, practice, and practice some more. Work from prototype photographs

as your guide. I use cheap foam brushes with beveled edges, and a plastic spoon. Get a foam

brush that is just slightly larger than the width of the inside between the rails. I like to tackle a

12"-18" section at a time, and move on to the next section. Start by pouring your ballast in the

center of the rails with your plastic spoon. Take your sponge brush and work your ballast

in between the ties until the ballast is just slightly below the ties. Don't worry about the edges, but

make sure you're happy with the center area first. If all looks good, and like your photo guide then

move onto the edges which is the easiest part, and finally the shoulders, which is the hardest part,

and where most modelers fail. And finally, you want the shoulders' edges to be parallel to the adjacent

rail for a professional look. If you're unhappy with the results, shop-vac your ballast using a nylon screen

to trap the ballast, and start over. You're not worried about the gluing stage at this point. I use a combination

of the foam brush, and my good ol' fingers to get the look I'm after. Some people use soft paint brushes, too.

But once you start to see nice evenly flowing ballast that looks like your photo, then you've done

the hard part, and the rest is cakewalk.

Hope this helps!

Thanks for the tips

Larry, thanks for the tips! The line I am modeling is actually a branch line. Still.. any raggedness was by accident, not design. The subroadbed in this section is level (I went down and double checked after reading your comment..). Any appearance otherwise is an artifact of the landscape and the photograph angle.

I actually have no problem making a nice delightfully even and well shaped shoulder when the ballast is dry. What I found with the WS fine ballast in an N scale application is that after it got glued down it got lumpy. I  found that I could do a little shaping after the ballast got wet by using a sculpting tool. However, at the end, it still looked like hell.

I just got some foam brushes to do some rock painting with. I will try cutting one down to use as a spreader. I had some success with a block of foam but at the end I was still fussing with getting the ballast off the ties and having the light material lose its nice shape and jump around as I did it. Using a toothpick to move things helped a little.

Still.. it is encouraging that with practice I can get it right although I would like to know how you are able to get those perfectly groomed shoulders to hold their position when wetted down.. also.. what kind of ballast material do you use?

Thanks.

Chris

This might help...............

I 'cut my teeth' learning at a large model railroad club of which I

was a member of for 11 years. I just had this 'passion' for ballasting that

I felt most modelers were lacking in.

What I was taught to use, and still have success at, is:

1. Get the ballast looking correct BEFORE using any gluing mediums.

    I cannot stress the importance of using prototype photos enough to

get the look 'just right.' Once you're happy with your 'test section,' go to

to the next step.

2. Now, this is where you need a well ventilated area otherwise you are playing

with DANGER! Use a respirator, or if that's not possible, get a fan to blow out the

fumes and open all possible windows!

Get a quart of lacquer, and lacquer thinner at your local hardware store, and a small

'oil can' type of applicator with a long nose. Mix equal parts lacquer to lacquer thinner with wooden sticks,

at a 1:1 ratio, and lightly squirt it in between the tracks, the ends, and finally the shoulders.

The beauty of this method is that will not ball-up your ballast like other methods can, and will

look exactly like your ballast prior to gluing. There are other techniques out there, but this

one has worked for me. Use very light pressure with your applicator.

3. Let your ballast dry for 24 hours minimum. Now, take some Elmer's white glue, and mix

it at a 1:1 ratio with water, and add just a few drops of dish detergent to act as a wetting agent,

and to help break the surface tension. I like to use water-based artists brushes for this step.

But make sure you clean your rails of the lacquer thinner first, otherwise the combination of

both the lacquer, and the white glue will be a real pain to clean up.

4. Make sure you remember which section needs the white glue fixative, otherwise the lacquer

mixture by itself will begin to break up over time.

5. And finally, let the white glue fixative dry 24 hours before cleaning the rail heads,

BUT, DO REMEMBER TO CLEAN UP THOSE RAILS WITHIN 24 HOURS, otherwise it adds

to the clean up time as white glue is amazingly strong stuff after it dries.

5. I will then blend the scenery up to  the shoulders' edges, because you can get this

unsightly 'wet mark' just at the edges, and this looks like some hobos just peed all over your

right of way.

Good luck to you!

Progress

Chris, it's looking good from my house! You're flocker is a success, and the abutments look great.

You've already gotten  a ton of good advice on the ballast, but truth be told I'm having a hard time seeing the lumpiness, at least from your photo. For what it's worth in HO, i run my hand over it after the glue has dried, and break off any offending pieces, vacuum, and redo, I'm not sure if that would help you here.

Odds once the scenery creeps up to the edge, the issues you have with it may be less visible (read noticeable) even to your trained eye. I wouldn't get too hung up on it at this stage, a lot of this comes from practice.
